CrewAI takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organization.
|
||||
If you believe you have found a security vulnerability in any CrewAI product or service, please report it to us as described below.
|
||||
## CrewAI Security Vulnerability Reporting Policy
|
||||
|
||||
## Reporting a Vulnerability
|
||||
Please do not report security vulnerabilities through public GitHub issues.
|
||||
To report a vulnerability, please email us at security@crewai.com.
|
||||
Please include the requested information listed below so that we can triage your report more quickly
|
||||
CrewAI prioritizes the security of our software products, services, and GitHub repositories. To promptly address vulnerabilities, follow these steps for reporting security issues:
|
||||
|
||||
- Type of issue (e.g. SQL injection, cross-site scripting, etc.)
|
||||
- Full paths of source file(s) related to the manifestation of the issue
|
||||
- The location of the affected source code (tag/branch/commit or direct URL)
|
||||
- Any special configuration required to reproduce the issue
|
||||
- Step-by-step instructions to reproduce the issue (please include screenshots if needed)
|
||||
- Proof-of-concept or exploit code (if possible)
|
||||
- Impact of the issue, including how an attacker might exploit the issue
|
||||
### Reporting Process
|
||||
Do **not** report vulnerabilities via public GitHub issues.
|
||||
|
||||
Once we have received your report, we will respond to you at the email address you provide. If the issue is confirmed, we will release a patch as soon as possible depending on the complexity of the issue.
|
||||
Email all vulnerability reports directly to:
|
||||
**security@crewai.com**
|
||||
|
||||
At this time, we are not offering a bug bounty program. Any rewards will be at our discretion.
|
||||
### Required Information
|
||||
To help us quickly validate and remediate the issue, your report must include:
|
||||
|
||||
- **Vulnerability Type:** Clearly state the vulnerability type (e.g., SQL injection, XSS, privilege escalation).
|
||||
- **Affected Source Code:** Provide full file paths and direct URLs (branch, tag, or commit).
|
||||
- **Reproduction Steps:** Include detailed, step-by-step instructions. Screenshots are recommended.
|
||||
- **Special Configuration:** Document any special settings or configurations required to reproduce.
|
||||
- **Proof-of-Concept (PoC):** Provide exploit or PoC code (if available).
|
||||
- **Impact Assessment:** Clearly explain the severity and potential exploitation scenarios.
|
||||
|
||||
### Our Response
|
||||
- We will acknowledge receipt of your report promptly via your provided email.
|
||||
- Confirmed vulnerabilities will receive priority remediation based on severity.
|
||||
- Patches will be released as swiftly as possible following verification.
|
||||
|
||||
### Reward Notice
|
||||
Currently, we do not offer a bug bounty program. Rewards, if issued, are discretionary.

### Using Crews and Flows Together
|
||||
|
||||
CrewAI's power truly shines when combining Crews with Flows to create sophisticated automation pipelines.
|
||||
CrewAI flows support logical operators like `or_` and `and_` to combine multiple conditions. This can be used with `@start`, `@listen`, or `@router` decorators to create complex triggering conditions.
|
||||
|
||||
- `or_`: Triggers when any of the specified conditions are met.
|
||||
- `and_`Triggers when all of the specified conditions are met.
|
||||
|
||||
Here's how you can orchestrate multiple Crews within a Flow:
|
||||
|
||||

||||

## Connecting Your Crew to a Model
|
||||
|
||||
CrewAI supports using various LLMs through a variety of connection options. By default your agents will use the OpenAI API when querying the model. However, there are several other ways to allow your agents to connect to models. For example, you can configure your agents to use a local model via the Ollama tool.
|
||||
|
||||
Please refer to the [Connect CrewAI to LLMs](https://docs.crewai.com/how-to/LLM-Connections/) page for details on configuring you agents' connections to models.

## How CrewAI Compares
|
||||
|
||||
**CrewAI's Advantage**: CrewAI is built with production in mind. It offers the flexibility of Autogen's conversational agents and the structured process approach of ChatDev, but without the rigidity. CrewAI's processes are designed to be dynamic and adaptable, fitting seamlessly into both development and production workflows.
|
||||
**CrewAI's Advantage**: CrewAI combines autonomous agent intelligence with precise workflow control through its unique Crews and Flows architecture. The framework excels at both high-level orchestration and low-level customization, enabling complex, production-grade systems with granular control.
|
||||
|
||||
- **Autogen**: While Autogen does good in creating conversational agents capable of working together, it lacks an inherent concept of process. In Autogen, orchestrating agents' interactions requires additional programming, which can become complex and cumbersome as the scale of tasks grows.
|
||||
- **LangGraph**: While LangGraph provides a foundation for building agent workflows, its approach requires significant boilerplate code and complex state management patterns. The framework's tight coupling with LangChain can limit flexibility when implementing custom agent behaviors or integrating with external systems.
|
||||
|
||||
*P.S. CrewAI demonstrates significant performance advantages over LangGraph, executing 5.76x faster in certain cases like this QA task example ([see comparison](https://github.com/crewAIInc/crewAI-examples/tree/main/Notebooks/CrewAI%20Flows%20%26%20Langgraph/QA%20Agent)) while achieving higher evaluation scores with faster completion times in certain coding tasks, like in this example ([detailed analysis](https://github.com/crewAIInc/crewAI-examples/blob/main/Notebooks/CrewAI%20Flows%20%26%20Langgraph/Coding%20Assistant/coding_assistant_eval.ipynb)).*
|
||||
|
||||
- **Autogen**: While Autogen excels at creating conversational agents capable of working together, it lacks an inherent concept of process. In Autogen, orchestrating agents' interactions requires additional programming, which can become complex and cumbersome as the scale of tasks grows.
|
||||
- **ChatDev**: ChatDev introduced the idea of processes into the realm of AI agents, but its implementation is quite rigid. Customizations in ChatDev are limited and not geared towards production environments, which can hinder scalability and flexibility in real-world applications.

# CrewAI Enterprise API
|
||||
|
||||
Welcome to the CrewAI Enterprise API reference. This API allows you to programmatically interact with your deployed crews, enabling integration with your applications, workflows, and services.
|
||||
|
||||
## Quick Start
|
||||
|
||||
<Steps>
|
||||
<Step title="Get Your API Credentials">
|
||||
Navigate to your crew's detail page in the CrewAI Enterprise dashboard and copy your Bearer Token from the Status tab.
|
||||
</Step>
|
||||
|
||||
<Step title="Discover Required Inputs">
|
||||
Use the `GET /inputs` endpoint to see what parameters your crew expects.
|
||||
</Step>
|
||||
|
||||
<Step title="Start a Crew Execution">
|
||||
Call `POST /kickoff` with your inputs to start the crew execution and receive a `kickoff_id`.
|
||||
</Step>
|
||||
|
||||
<Step title="Monitor Progress">
|
||||
Use `GET /status/{kickoff_id}` to check execution status and retrieve results.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Authentication
|
||||
|
||||
All API requests require authentication using a Bearer token. Include your token in the `Authorization` header:
|
||||
|
||||
```bash
|
||||
curl -H "Authorization: Bearer YOUR_CREW_TOKEN" \
|
||||
https://your-crew-url.crewai.com/inputs
|
||||
```
|
||||
|
||||
### Token Types
|
||||
|
||||
| Token Type | Scope | Use Case |
|
||||
|:-----------|:--------|:----------|
|
||||
| **Bearer Token** | Organization-level access | Full crew operations, ideal for server-to-server integration |
|
||||
| **User Bearer Token** | User-scoped access | Limited permissions, suitable for user-specific operations |
|
||||
|
||||
<Tip>
|
||||
You can find both token types in the Status tab of your crew's detail page in the CrewAI Enterprise dashboard.
|
||||
</Tip>
|
||||
|
||||
## Base URL
|
||||
|
||||
Each deployed crew has its own unique API endpoint:
|
||||
|
||||
```
|
||||
https://your-crew-name.crewai.com
|
||||
```
|
||||
|
||||
Replace `your-crew-name` with your actual crew's URL from the dashboard.
|
||||
|
||||
## Typical Workflow
|
||||
|
||||
1. **Discovery**: Call `GET /inputs` to understand what your crew needs
|
||||
2. **Execution**: Submit inputs via `POST /kickoff` to start processing
|
||||
3. **Monitoring**: Poll `GET /status/{kickoff_id}` until completion
|
||||
4. **Results**: Extract the final output from the completed response
|
||||
|
||||
## Error Handling
|
||||
|
||||
The API uses standard HTTP status codes:
|
||||
|
||||
| Code | Meaning |
|
||||
|------|:--------|
|
||||
| `200` | Success |
|
||||
| `400` | Bad Request - Invalid input format |
|
||||
| `401` | Unauthorized - Invalid bearer token |
|
||||
| `404` | Not Found - Resource doesn't exist |
|
||||
| `422` | Validation Error - Missing required inputs |
|
||||
| `500` | Server Error - Contact support |
|
||||
|
||||
## Interactive Testing
|
||||
|
||||
<Info>
|
||||
**Why no "Send" button?** Since each CrewAI Enterprise user has their own unique crew URL, we use **reference mode** instead of an interactive playground to avoid confusion. This shows you exactly what the requests should look like without non-functional send buttons.
|
||||
</Info>
|
||||
|
||||
Each endpoint page shows you:
|
||||
- ✅ **Exact request format** with all parameters
|
||||
- ✅ **Response examples** for success and error cases
|
||||
- ✅ **Code samples** in multiple languages (cURL, Python, JavaScript, etc.)
|
||||
- ✅ **Authentication examples** with proper Bearer token format

## What is an agent?
|
||||
## Overview of an Agent
|
||||
|
||||
An agent is an **autonomous unit** programmed to:
|
||||
<ul>
|
||||
<li class='leading-3'>Perform tasks</li>
|
||||
<li class='leading-3'>Make decisions</li>
|
||||
<li class='leading-3'>Communicate with other agents</li>
|
||||
</ul>
|
||||
In the CrewAI framework, an `Agent` is an autonomous unit that can:
|
||||
- Perform specific tasks
|
||||
- Make decisions based on its role and goal
|
||||
- Use tools to accomplish objectives
|
||||
- Communicate and collaborate with other agents
|
||||
- Maintain memory of interactions
|
||||
- Delegate tasks when allowed
|
||||
|
||||
<Tip>
|
||||
Think of an agent as a member of a team, with specific skills and a particular job to do. Agents can have different roles like `Researcher`, `Writer`, or `Customer Support`, each contributing to the overall goal of the crew.
|
||||
Think of an agent as a specialized team member with specific skills, expertise, and responsibilities. For example, a `Researcher` agent might excel at gathering and analyzing information, while a `Writer` agent might be better at creating content.
|
||||
</Tip>
|
||||
|
||||
## Agent attributes
|
||||
<Note type="info" title="Enterprise Enhancement: Visual Agent Builder">
|
||||
CrewAI Enterprise includes a Visual Agent Builder that simplifies agent creation and configuration without writing code. Design your agents visually and test them in real-time.
|
||||
|
||||
| Attribute | Parameter | Description |
|
||||
| :------------------------- | :--------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| **Role** | `role` | Defines the agent's function within the crew. It determines the kind of tasks the agent is best suited for. |
|
||||
| **Goal** | `goal` | The individual objective that the agent aims to achieve. It guides the agent's decision-making process. |
|
||||
| **Backstory** | `backstory`| Provides context to the agent's role and goal, enriching the interaction and collaboration dynamics. |
|
||||
| **LLM** *(optional)* | `llm` | Represents the language model that will run the agent. It dynamically fetches the model name from the `OPENAI_MODEL_NAME` environment variable, defaulting to "gpt-4" if not specified. |
|
||||
| **Tools** *(optional)* | `tools` | Set of capabilities or functions that the agent can use to perform tasks. Expected to be instances of custom classes compatible with the agent's execution environment. Tools are initialized with a default value of an empty list. |
|
||||
| **Function Calling LLM** *(optional)* | `function_calling_llm` | Specifies the language model that will handle the tool calling for this agent, overriding the crew function calling LLM if passed. Default is `None`. |
|
||||
| **Max Iter** *(optional)* | `max_iter` | Max Iter is the maximum number of iterations the agent can perform before being forced to give its best answer. Default is `25`. |
|
||||
| **Max RPM** *(optional)* | `max_rpm` | Max RPM is the maximum number of requests per minute the agent can perform to avoid rate limits. It's optional and can be left unspecified, with a default value of `None`. |
|
||||
| **Max Execution Time** *(optional)* | `max_execution_time` | Max Execution Time is the maximum execution time for an agent to execute a task. It's optional and can be left unspecified, with a default value of `None`, meaning no max execution time. |
|
||||
| **Verbose** *(optional)* | `verbose` | Setting this to `True` configures the internal logger to provide detailed execution logs, aiding in debugging and monitoring. Default is `False`. |
|
||||
| **Allow Delegation** *(optional)* | `allow_delegation` | Agents can delegate tasks or questions to one another, ensuring that each task is handled by the most suitable agent. Default is `False`. |
|
||||
| **Step Callback** *(optional)* | `step_callback` | A function that is called after each step of the agent. This can be used to log the agent's actions or to perform other operations. It will overwrite the crew `step_callback`. |
|
||||
| **Cache** *(optional)* | `cache` | Indicates if the agent should use a cache for tool usage. Default is `True`. |
|
||||
| **System Template** *(optional)* | `system_template` | Specifies the system format for the agent. Default is `None`. |
|
||||
| **Prompt Template** *(optional)* | `prompt_template` | Specifies the prompt format for the agent. Default is `None`. |
|
||||
| **Response Template** *(optional)* | `response_template` | Specifies the response format for the agent. Default is `None`. |
|
||||
| **Allow Code Execution** *(optional)* | `allow_code_execution` | Enable code execution for the agent. Default is `False`. |
|
||||
| **Max Retry Limit** *(optional)* | `max_retry_limit` | Maximum number of retries for an agent to execute a task when an error occurs. Default is `2`. |
|
||||
| **Use System Prompt** *(optional)* | `use_system_prompt` | Adds the ability to not use system prompt (to support o1 models). Default is `True`. |
|
||||
| **Respect Context Window** *(optional)* | `respect_context_window` | Summary strategy to avoid overflowing the context window. Default is `True`. |
|
||||
| **Code Execution Mode** *(optional)* | `code_execution_mode` | Determines the mode for code execution: 'safe' (using Docker) or 'unsafe' (direct execution on the host machine). Default is `safe`. |
|
||||

|
||||
|
||||
## Creating an agent
|
||||
|
||||
<Note>
|
||||
**Agent interaction**: Agents can interact with each other using CrewAI's built-in delegation and communication mechanisms. This allows for dynamic task management and problem-solving within the crew.
|
||||
The Visual Agent Builder enables:
|
||||
- Intuitive agent configuration with form-based interfaces
|
||||
- Real-time testing and validation
|
||||
- Template library with pre-configured agent types
|
||||
- Easy customization of agent attributes and behaviors
|
||||
</Note>
|
||||
|
||||
To create an agent, you would typically initialize an instance of the `Agent` class with the desired properties. Here's a conceptual example including all attributes:
|
||||
## Agent Attributes
|
||||
|
||||
```python Code example
|
||||
| Attribute | Parameter | Type | Description |
|
||||
| :-------------------------------------- | :----------------------- | :---------------------------- | :------------------------------------------------------------------------------------------------------------------- |
|
||||
| **Role** | `role` | `str` | Defines the agent's function and expertise within the crew. |
|
||||
| **Goal** | `goal` | `str` | The individual objective that guides the agent's decision-making. |

## Creating Agents
|
||||
|
||||
There are two ways to create agents in CrewAI: using **YAML configuration (recommended)** or defining them **directly in code**.
|
||||
|
||||
### YAML Configuration (Recommended)
|
||||
|
||||
Using YAML configuration provides a cleaner, more maintainable way to define agents. We strongly recommend using this approach in your CrewAI projects.
|
||||
|
||||
After creating your CrewAI project as outlined in the [Installation](/installation) section, navigate to the `src/latest_ai_development/config/agents.yaml` file and modify the template to match your requirements.
|
||||
|
||||
<Note>
|
||||
Variables in your YAML files (like `{topic}`) will be replaced with values from your inputs when running the crew:
|
||||
```python Code
|
||||
crew.kickoff(inputs={'topic': 'AI Agents'})
|
||||
```
|
||||
</Note>
|
||||
|
||||
Here's an example of how to configure agents using YAML:
|
||||
|
||||
```yaml agents.yaml
|
||||
# src/latest_ai_development/config/agents.yaml
|
||||
researcher:
|
||||
role: >
|
||||
{topic} Senior Data Researcher
|
||||
goal: >
|
||||
Uncover cutting-edge developments in {topic}
|
||||
backstory: >
|
||||
You're a seasoned researcher with a knack for uncovering the latest
|
||||
developments in {topic}. Known for your ability to find the most relevant
|
||||
information and present it in a clear and concise manner.
|
||||
|
||||
reporting_analyst:
|
||||
role: >
|
||||
{topic} Reporting Analyst
|
||||
goal: >
|
||||
Create detailed reports based on {topic} data analysis and research findings
|
||||
backstory: >
|
||||
You're a meticulous analyst with a keen eye for detail. You're known for
|
||||
your ability to turn complex data into clear and concise reports, making
|
||||
it easy for others to understand and act on the information you provide.
|
||||
```
|
||||
|
||||
To use this YAML configuration in your code, create a crew class that inherits from `CrewBase`:
|
||||
|
||||
```python Code
|
||||
# src/latest_ai_development/crew.py
|
||||
from crewai import Agent, Crew, Process
|
||||
from crewai.project import CrewBase, agent, crew
|
||||
from crewai_tools import SerperDevTool
|
||||
|
||||
@CrewBase
|
||||
class LatestAiDevelopmentCrew():
|
||||
"""LatestAiDevelopment crew"""
|
||||
|
||||
agents_config = "config/agents.yaml"
|
||||
|
||||
@agent
|
||||
def researcher(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['researcher'], # type: ignore[index]
|
||||
verbose=True,
|
||||
tools=[SerperDevTool()]
|
||||
)
|
||||
|
||||
@agent
|
||||
def reporting_analyst(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['reporting_analyst'], # type: ignore[index]
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
<Note>
|
||||
The names you use in your YAML files (`agents.yaml`) should match the method names in your Python code.
|
||||
</Note>
|
||||
|
||||
### Direct Code Definition
|
||||
|
||||
You can create agents directly in code by instantiating the `Agent` class. Here's a comprehensive example showing all available parameters:
|
||||
|
||||
```python Code
|
||||
from crewai import Agent
|
||||
from crewai_tools import SerperDevTool
|
||||
|
||||
# Create an agent with all available parameters
|
||||
agent = Agent(
|
||||
role='Data Analyst',
|
||||
goal='Extract actionable insights',
|
||||
backstory="""You're a data analyst at a large company.

|
||||
)
|
||||
```
|
||||
|
||||
## Setting prompt templates
|
||||
Let's break down some key parameter combinations for common use cases:
|
||||
|
||||
Prompt templates are used to format the prompt for the agent. You can use to update the system, regular and response templates for the agent. Here's an example of how to set prompt templates:
|
||||
#### Basic Research Agent
|
||||
```python Code
|
||||
research_agent = Agent(
|
||||
role="Research Analyst",
|
||||
goal="Find and summarize information about specific topics",
|
||||
backstory="You are an experienced researcher with attention to detail",
|
||||
tools=[SerperDevTool()],
|
||||
verbose=True # Enable logging for debugging
|
||||
)
|
||||
```
|
||||
|
||||
```python Code example
|
||||
agent = Agent(
|
||||
role="{topic} specialist",
|
||||
goal="Figure {goal} out",
|
||||
backstory="I am the master of {role}",
|
||||
system_template="""<|start_header_id|>system<|end_header_id|>
|
||||
#### Code Development Agent
|
||||
```python Code
|
||||
dev_agent = Agent(
|
||||
role="Senior Python Developer",
|
||||
goal="Write and debug Python code",
|
||||
backstory="Expert Python developer with 10 years of experience",
|
||||
allow_code_execution=True,
|
||||
code_execution_mode="safe", # Uses Docker for safety
|
||||
max_execution_time=300, # 5-minute timeout
|
||||
max_retry_limit=3 # More retries for complex code tasks
|
||||
)
|
||||
```
|
||||
|
||||
#### Long-Running Analysis Agent
|
||||
```python Code
|
||||
analysis_agent = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Perform deep analysis of large datasets",
|
||||
backstory="Specialized in big data analysis and pattern recognition",
|
||||
memory=True,
|
||||
respect_context_window=True,
|
||||
max_rpm=10, # Limit API calls
|
||||
function_calling_llm="gpt-4o-mini" # Cheaper model for tool calls
|
||||
)
|
||||
```
|
||||
|
||||
#### Custom Template Agent
|
||||
```python Code
|
||||
custom_agent = Agent(
|
||||
role="Customer Service Representative",
|
||||
goal="Assist customers with their inquiries",
|
||||
backstory="Experienced in customer support with a focus on satisfaction",
|
||||
system_template="""<|start_header_id|>system<|end_header_id|>
|
||||
{{ .System }}<|eot_id|>""",
|
||||
prompt_template="""<|start_header_id|>user<|end_header_id|>
|
||||
prompt_template="""<|start_header_id|>user<|end_header_id|>
|
||||
{{ .Prompt }}<|eot_id|>""",
|
||||
response_template="""<|start_header_id|>assistant<|end_header_id|>
|
||||
response_template="""<|start_header_id|>assistant<|end_header_id|>
|
||||
{{ .Response }}<|eot_id|>""",
|
||||
)
|
||||
```
|
||||
|
||||
## Bring your third-party agents
|
||||
|
||||
Extend your third-party agents like LlamaIndex, Langchain, Autogen or fully custom agents using the the CrewAI's `BaseAgent` class.
|
||||
|
||||
<Note>
|
||||
**BaseAgent** includes attributes and methods required to integrate with your crews to run and delegate tasks to other agents within your own crew.
|
||||
</Note>
|
||||
|
||||
CrewAI is a universal multi-agent framework that allows for all agents to work together to automate tasks and solve problems.
|
||||
|
||||
```python Code example
|
||||
from crewai import Agent, Task, Crew
|
||||
from custom_agent import CustomAgent # You need to build and extend your own agent logic with the CrewAI BaseAgent class then import it here.
|
||||
|
||||
from langchain.agents import load_tools
|
||||
|
||||
langchain_tools = load_tools(["google-serper"], llm=llm)
|
||||
|
||||
agent1 = CustomAgent(
|
||||
role="agent role",
|
||||
goal="who is {input}?",
|
||||
backstory="agent backstory",
|
||||
verbose=True,
|
||||
#### Date-Aware Agent with Reasoning
|
||||
```python Code
|
||||
strategic_agent = Agent(
|
||||
role="Market Analyst",
|
||||
goal="Track market movements with precise date references and strategic planning",
|
||||
backstory="Expert in time-sensitive financial analysis and strategic reporting",
|
||||
inject_date=True, # Automatically inject current date into tasks
|
||||
date_format="%B %d, %Y", # Format as "May 21, 2025"
|
||||
reasoning=True, # Enable strategic planning
|
||||
max_reasoning_attempts=2, # Limit planning iterations
|
||||
verbose=True
|
||||
)
|
||||
|
||||
task1 = Task(
|
||||
expected_output="a short biography of {input}",
|
||||
description="a short biography of {input}",
|
||||
agent=agent1,
|
||||
)
|
||||
|
||||
agent2 = Agent(
|
||||
role="agent role",
|
||||
goal="summarize the short bio for {input} and if needed do more research",
|
||||
backstory="agent backstory",
|
||||
verbose=True,
|
||||
)
|
||||
|
||||
task2 = Task(
|
||||
description="a tldr summary of the short biography",
|
||||
expected_output="5 bullet point summary of the biography",
|
||||
agent=agent2,
|
||||
context=[task1],
|
||||
)
|
||||
|
||||
my_crew = Crew(agents=[agent1, agent2], tasks=[task1, task2])
|
||||
crew = my_crew.kickoff(inputs={"input": "Mark Twain"})
|
||||
```
|
||||
|
||||
## Conclusion
|
||||
#### Reasoning Agent
|
||||
```python Code
|
||||
reasoning_agent = Agent(
|
||||
role="Strategic Planner",
|
||||
goal="Analyze complex problems and create detailed execution plans",
|
||||
backstory="Expert strategic planner who methodically breaks down complex challenges",
|
||||
reasoning=True, # Enable reasoning and planning
|
||||
max_reasoning_attempts=3, # Limit reasoning attempts
|
||||
max_iter=30, # Allow more iterations for complex planning
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
Agents are the building blocks of the CrewAI framework. By understanding how to define and interact with agents,
|
||||
you can create sophisticated AI systems that leverage the power of collaborative intelligence. The `code_execution_mode` attribute provides flexibility in how agents execute code, allowing for both secure and direct execution options.
|
||||
#### Multimodal Agent
|
||||
```python Code
|
||||
multimodal_agent = Agent(
|
||||
role="Visual Content Analyst",
|
||||
goal="Analyze and process both text and visual content",
|
||||
backstory="Specialized in multimodal analysis combining text and image understanding",
|
||||
multimodal=True, # Enable multimodal capabilities
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
### Parameter Details
|
||||
|
||||
#### Critical Parameters
|
||||
- `role`, `goal`, and `backstory` are required and shape the agent's behavior
|

||||
#### Execution Control
|
||||
- `max_iter`: Maximum attempts before giving best answer
|
||||
- `max_execution_time`: Timeout in seconds
|
||||
- `max_rpm`: Rate limiting for API calls
|
||||
- `max_retry_limit`: Retries on error
|
||||
|
||||
#### Code Execution

|
||||
</Note>
|
||||
|
||||
<Note>
|
||||
When using custom templates, you can use variables like `{role}`, `{goal}`, and `{backstory}` in your templates. These will be automatically populated during execution.
|
||||
</Note>
|
||||
|
||||
## Agent Tools
|
||||
|
||||
Agents can be equipped with various tools to enhance their capabilities. CrewAI supports tools from:
|
||||
- [CrewAI Toolkit](https://github.com/joaomdmoura/crewai-tools)
|
||||
- [LangChain Tools](https://python.langchain.com/docs/integrations/tools)
|
||||
|
||||
Here's how to add tools to an agent:
|
||||
|
||||
```python Code
|
||||
from crewai import Agent
|
||||
from crewai_tools import SerperDevTool, WikipediaTools
|
||||
|
||||
# Create tools
|
||||
search_tool = SerperDevTool()
|
||||
wiki_tool = WikipediaTools()
|
||||
|
||||
# Add tools to agent
|
||||
researcher = Agent(
|
||||
role="AI Technology Researcher",
|
||||
goal="Research the latest AI developments",
|
||||
tools=[search_tool, wiki_tool],
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
## Agent Memory and Context
|
||||
|
||||
Agents can maintain memory of their interactions and use context from previous tasks. This is particularly useful for complex workflows where information needs to be retained across multiple tasks.
|
||||
|
||||
```python Code
|
||||
from crewai import Agent
|
||||
|
||||
analyst = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze and remember complex data patterns",
|
||||
memory=True, # Enable memory
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
<Note>
|
||||
When `memory` is enabled, the agent will maintain context across multiple interactions, improving its ability to handle complex, multi-step tasks.
|
||||
</Note>
|
||||
|
||||
## Context Window Management
|
||||
|
||||
CrewAI includes sophisticated automatic context window management to handle situations where conversations exceed the language model's token limits. This powerful feature is controlled by the `respect_context_window` parameter.
|
||||
|
||||
### How Context Window Management Works
|
||||
|
||||
When an agent's conversation history grows too large for the LLM's context window, CrewAI automatically detects this situation and can either:
|
||||
|
||||
1. **Automatically summarize content** (when `respect_context_window=True`)
|
||||
2. **Stop execution with an error** (when `respect_context_window=False`)
|
||||
|
||||
### Automatic Context Handling (`respect_context_window=True`)
|
||||
|
||||
This is the **default and recommended setting** for most use cases. When enabled, CrewAI will:
|
||||
|
||||
```python Code
|
||||
# Agent with automatic context management (default)
|
||||
smart_agent = Agent(
|
||||
role="Research Analyst",
|
||||
goal="Analyze large documents and datasets",
|
||||
backstory="Expert at processing extensive information",
|
||||
respect_context_window=True, # 🔑 Default: auto-handle context limits
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
**What happens when context limits are exceeded:**
|
||||
- ⚠️ **Warning message**: `"Context length exceeded. Summarizing content to fit the model context window."`
|
||||
- 🔄 **Automatic summarization**: CrewAI intelligently summarizes the conversation history
|
||||
- ✅ **Continued execution**: Task execution continues seamlessly with the summarized context
|
||||
- 📝 **Preserved information**: Key information is retained while reducing token count
|
||||
|
||||
### Strict Context Limits (`respect_context_window=False`)
|
||||
|
||||
When you need precise control and prefer execution to stop rather than lose any information:
|
||||
|
||||
```python Code
|
||||
# Agent with strict context limits
|
||||
strict_agent = Agent(
|
||||
role="Legal Document Reviewer",
|
||||
goal="Provide precise legal analysis without information loss",
|
||||
backstory="Legal expert requiring complete context for accurate analysis",
|
||||
respect_context_window=False, # ❌ Stop execution on context limit
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
**What happens when context limits are exceeded:**
|
||||
- ❌ **Error message**: `"Context length exceeded. Consider using smaller text or RAG tools from crewai_tools."`
|
||||
- 🛑 **Execution stops**: Task execution halts immediately
|
||||
- 🔧 **Manual intervention required**: You need to modify your approach
|
||||
|
||||
### Choosing the Right Setting
|
||||
|
||||
#### Use `respect_context_window=True` (Default) when:
|
||||
- **Processing large documents** that might exceed context limits
|
||||
- **Long-running conversations** where some summarization is acceptable
|
||||
- **Research tasks** where general context is more important than exact details
|
||||
- **Prototyping and development** where you want robust execution
|
||||
|
||||
```python Code
|
||||
# Perfect for document processing
|
||||
document_processor = Agent(
|
||||
role="Document Analyst",
|
||||
goal="Extract insights from large research papers",
|
||||
backstory="Expert at analyzing extensive documentation",
|
||||
respect_context_window=True, # Handle large documents gracefully
|
||||
max_iter=50, # Allow more iterations for complex analysis
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
#### Use `respect_context_window=False` when:
|
||||
- **Precision is critical** and information loss is unacceptable
|
||||
- **Legal or medical tasks** requiring complete context
|
||||
- **Code review** where missing details could introduce bugs
|
||||
- **Financial analysis** where accuracy is paramount
|
||||
|
||||
```python Code
|
||||
# Perfect for precision tasks
|
||||
precision_agent = Agent(
|
||||
role="Code Security Auditor",
|
||||
goal="Identify security vulnerabilities in code",
|
||||
backstory="Security expert requiring complete code context",
|
||||
respect_context_window=False, # Prefer failure over incomplete analysis
|
||||
max_retry_limit=1, # Fail fast on context issues
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
### Alternative Approaches for Large Data
|
||||
|
||||
When dealing with very large datasets, consider these strategies:
|
||||
|
||||
#### 1. Use RAG Tools
|
||||
```python Code
|
||||
from crewai_tools import RagTool
|
||||
|
||||
# Create RAG tool for large document processing
|
||||
rag_tool = RagTool()
|
||||
|
||||
rag_agent = Agent(
|
||||
role="Research Assistant",
|
||||
goal="Query large knowledge bases efficiently",
|
||||
backstory="Expert at using RAG tools for information retrieval",
|
||||
tools=[rag_tool], # Use RAG instead of large context windows
|
||||
respect_context_window=True,
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
#### 2. Use Knowledge Sources
|
||||
```python Code
|
||||
# Use knowledge sources instead of large prompts
|
||||
knowledge_agent = Agent(
|
||||
role="Knowledge Expert",
|
||||
goal="Answer questions using curated knowledge",
|
||||
backstory="Expert at leveraging structured knowledge sources",
|
||||
knowledge_sources=[your_knowledge_sources], # Pre-processed knowledge
|
||||
respect_context_window=True,
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
### Context Window Best Practices
|
||||
|
||||
1. **Monitor Context Usage**: Enable `verbose=True` to see context management in action
|
||||
2. **Design for Efficiency**: Structure tasks to minimize context accumulation
|
||||
3. **Use Appropriate Models**: Choose LLMs with context windows suitable for your tasks
|
||||
4. **Test Both Settings**: Try both `True` and `False` to see which works better for your use case
|
||||
5. **Combine with RAG**: Use RAG tools for very large datasets instead of relying solely on context windows
|
||||
|
||||
### Troubleshooting Context Issues
|
||||
|
||||
**If you're getting context limit errors:**
|
||||
```python Code
|
||||
# Quick fix: Enable automatic handling
|
||||
agent.respect_context_window = True
|
||||
|
||||
# Better solution: Use RAG tools for large data
|
||||
from crewai_tools import RagTool
|
||||
agent.tools = [RagTool()]
|
||||
|
||||
# Alternative: Break tasks into smaller pieces
|
||||
# Or use knowledge sources instead of large prompts
|
||||
```
|
||||
|
||||
**If automatic summarization loses important information:**
|
||||
```python Code
|
||||
# Disable auto-summarization and use RAG instead
|
||||
agent = Agent(
|
||||
role="Detailed Analyst",
|
||||
goal="Maintain complete information accuracy",
|
||||
backstory="Expert requiring full context",
|
||||
respect_context_window=False, # No summarization
|
||||
tools=[RagTool()], # Use RAG for large data
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
<Note>
|
||||
The context window management feature works automatically in the background. You don't need to call any special functions - just set `respect_context_window` to your preferred behavior and CrewAI handles the rest!
|
||||
</Note>
|
||||
|
||||
## Important Considerations and Best Practices
|
||||
|
||||
### Security and Code Execution
|
||||
- When using `allow_code_execution`, be cautious with user input and always validate it
|
||||
- Use `code_execution_mode: "safe"` (Docker) in production environments
|
||||
- Consider setting appropriate `max_execution_time` limits to prevent infinite loops
|
||||
|
||||
### Performance Optimization
|
||||
- Use `respect_context_window: true` to prevent token limit issues
|
||||
- Set appropriate `max_rpm` to avoid rate limiting
|
||||
- Enable `cache: true` to improve performance for repetitive tasks
|
||||
- Adjust `max_iter` and `max_retry_limit` based on task complexity
|
||||
|
||||
### Memory and Context Management
|
||||
- Leverage `knowledge_sources` for domain-specific information
|
||||
- Configure `embedder` when using custom embedding models
|
||||
- Use custom templates (`system_template`, `prompt_template`, `response_template`) for fine-grained control over agent behavior
|
||||
|
||||
### Advanced Features
|
||||
- Enable `reasoning: true` for agents that need to plan and reflect before executing complex tasks
|
||||
- Set appropriate `max_reasoning_attempts` to control planning iterations (None for unlimited attempts)
|
||||
- Use `inject_date: true` to provide agents with current date awareness for time-sensitive tasks
|
||||
- Customize the date format with `date_format` using standard Python datetime format codes
|
||||
- Enable `multimodal: true` for agents that need to process both text and visual content
|
||||
|
||||
### Agent Collaboration
|
||||
- Enable `allow_delegation: true` when agents need to work together
|
||||
- Use `step_callback` to monitor and log agent interactions
|
||||
- Consider using different LLMs for different purposes:
|
||||
- Main `llm` for complex reasoning
|
||||
- `function_calling_llm` for efficient tool usage
|
||||
|
||||
### Date Awareness and Reasoning
|
||||
- Use `inject_date: true` to provide agents with current date awareness for time-sensitive tasks
|
||||
- Customize the date format with `date_format` using standard Python datetime format codes
|
||||
- Valid format codes include: %Y (year), %m (month), %d (day), %B (full month name), etc.
|
||||
- Invalid date formats will be logged as warnings and will not modify the task description
|
||||
- Enable `reasoning: true` for complex tasks that benefit from upfront planning and reflection
|
||||
|
||||
### Model Compatibility
|
||||
- Set `use_system_prompt: false` for older models that don't support system messages
|
||||
- Ensure your chosen `llm` supports the features you need (like function calling)
|
||||
|
||||
## Troubleshooting Common Issues
|
||||
|
||||
1. **Rate Limiting**: If you're hitting API rate limits:
|
||||
- Implement appropriate `max_rpm`
|
||||
- Use caching for repetitive operations
|
||||
- Consider batching requests
|
||||
|
||||
2. **Context Window Errors**: If you're exceeding context limits:
|
||||
- Enable `respect_context_window`
|
||||
- Use more efficient prompts
|
||||
- Clear agent memory periodically
|
||||
|
||||
3. **Code Execution Issues**: If code execution fails:
|
||||
- Verify Docker is installed for safe mode
|
||||
- Check execution permissions
|
||||
- Review code sandbox settings
|
||||
|
||||
4. **Memory Issues**: If agent responses seem inconsistent:
|
||||
- Check knowledge source configuration
|
||||
- Review conversation history management
|
||||
|
||||
Remember that agents are most effective when configured according to their specific use case. Take time to understand your requirements and adjust these parameters accordingly.

### 9. Chat
|
||||
|
||||
### 9. API Keys
|
||||
Starting in version `0.98.0`, when you run the `crewai chat` command, you start an interactive session with your crew. The AI assistant will guide you by asking for necessary inputs to execute the crew. Once all inputs are provided, the crew will execute its tasks.
|
||||
|
||||
After receiving the results, you can continue interacting with the assistant for further instructions or questions.
|
||||
|
||||
```shell Terminal
|
||||
crewai chat
|
||||
```
|
||||
<Note>
|
||||
Ensure you execute these commands from your CrewAI project's root directory.
|
||||
</Note>
|
||||
<Note>
|
||||
IMPORTANT: Set the `chat_llm` property in your `crew.py` file to enable this command.
|
||||
|
||||
```python
|
||||
@crew
|
||||
def crew(self) -> Crew:
|
||||
return Crew(
|
||||
agents=self.agents,
|
||||
tasks=self.tasks,
|
||||
process=Process.sequential,
|
||||
verbose=True,
|
||||
chat_llm="gpt-4o", # LLM for chat orchestration
|
||||
)
|
||||
```
|
||||
</Note>
|
||||
|
||||
### 10. Deploy
|
||||
|
||||
Deploy the crew or flow to [CrewAI Enterprise](https://app.crewai.com).
|
||||
|
||||
- **Authentication**: You need to be authenticated to deploy to CrewAI Enterprise.
|
||||
```shell Terminal
|
||||
crewai signup
|
||||
```
|
||||
If you already have an account, you can login with:
|
||||
```shell Terminal
|
||||
crewai login
|
||||
```
|
||||
|
||||
- **Create a deployment**: Once you are authenticated, you can create a deployment for your crew or flow from the root of your localproject.
|
||||
```shell Terminal
|
||||
crewai deploy create
|
||||
```
|
||||
- Reads your local project configuration.
|
||||
- Prompts you to confirm the environment variables (like `OPENAI_API_KEY`, `SERPER_API_KEY`) found locally. These will be securely stored with the deployment on the Enterprise platform. Ensure your sensitive keys are correctly configured locally (e.g., in a `.env` file) before running this.
|
||||
|
||||
### 11. Organization Management
|
||||
|
||||
Manage your CrewAI Enterprise organizations.
|
||||
|
||||
```shell Terminal
|
||||
crewai org [COMMAND] [OPTIONS]
|
||||
```
|
||||
|
||||
#### Commands:
|
||||
|
||||
- `list`: List all organizations you belong to
|
||||
```shell Terminal
|
||||
crewai org list
|
||||
```
|
||||
|
||||
- `current`: Display your currently active organization
|
||||
```shell Terminal
|
||||
crewai org current
|
||||
```
|
||||
|
||||
- `switch`: Switch to a specific organization
|
||||
```shell Terminal
|
||||
crewai org switch <organization_id>
|
||||
```
|
||||
|
||||
<Note>
|
||||
You must be authenticated to CrewAI Enterprise to use these organization management commands.
|
||||
</Note>
|
||||
|
||||
- **Create a deployment** (continued):
|
||||
- Links the deployment to the corresponding remote GitHub repository (it usually detects this automatically).
|
||||
|
||||
- **Deploy the Crew**: Once you are authenticated, you can deploy your crew or flow to CrewAI Enterprise.
|
||||
```shell Terminal
|
||||
crewai deploy push
|
||||
```
|
||||
- Initiates the deployment process on the CrewAI Enterprise platform.
|
||||
- Upon successful initiation, it will output the Deployment created successfully! message along with the Deployment Name and a unique Deployment ID (UUID).
|
||||
|
||||
- **Deployment Status**: You can check the status of your deployment with:
|
||||
```shell Terminal
|
||||
crewai deploy status
|
||||
```
|
||||
This fetches the latest deployment status of your most recent deployment attempt (e.g., `Building Images for Crew`, `Deploy Enqueued`, `Online`).
|
||||
|
||||
- **Deployment Logs**: You can check the logs of your deployment with:
|
||||
```shell Terminal
|
||||
crewai deploy logs
|
||||
```
|
||||
This streams the deployment logs to your terminal.
|
||||
|
||||
- **List deployments**: You can list all your deployments with:
|
||||
```shell Terminal
|
||||
crewai deploy list
|
||||
```
|
||||
This lists all your deployments.
|
||||
|
||||
- **Delete a deployment**: You can delete a deployment with:
|
||||
```shell Terminal
|
||||
crewai deploy remove
|
||||
```
|
||||
This deletes the deployment from the CrewAI Enterprise platform.
|
||||
|
||||
- **Help Command**: You can get help with the CLI with:
|
||||
```shell Terminal
|
||||
crewai deploy --help
|
||||
```
|
||||
This shows the help message for the CrewAI Deploy CLI.

Collaboration in CrewAI enables agents to work together as a team by delegating tasks and asking questions to leverage each other's expertise. When `allow_delegation=True`, agents automatically gain access to powerful collaboration tools.
|
||||
|
||||
- **Information Sharing**: Ensures all agents are well-informed and can contribute effectively by sharing data and findings.
|
||||
- **Task Assistance**: Allows agents to seek help from peers with the required expertise for specific tasks.
|
||||
- **Resource Allocation**: Optimizes task execution through the efficient distribution and sharing of resources among agents.
|
||||

|
||||
|
||||
## Enhanced Attributes for Improved Collaboration
|
||||
```python
|
||||
from crewai import Agent, Crew, Task
|
||||
|
||||
The `Crew` class has been enriched with several attributes to support advanced functionalities:
|
||||

||||
role="Content Writer",
|
||||
goal="Create engaging content based on research",
|
||||
backstory="Skilled writer who transforms research into compelling content",
|
||||
allow_delegation=True, # 🔑 Enables asking questions to other agents
|
||||
verbose=True
|
||||
)
|
||||
|
||||
## Delegation (Dividing to Conquer)
|
||||
# Agents can now collaborate automatically
|
||||
crew = Crew(
|
||||
agents=[researcher, writer],
|
||||
tasks=[...],
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
Delegation enhances functionality by allowing agents to intelligently assign tasks or seek help, thereby amplifying the crew's overall capability.
|
||||
## How Agent Collaboration Works
|
||||
|
||||
## Implementing Collaboration and Delegation
|
||||
When `allow_delegation=True`, CrewAI automatically provides agents with two powerful tools:
|
||||
|
||||
Setting up a crew involves defining the roles and capabilities of each agent. CrewAI seamlessly manages their interactions, ensuring efficient collaboration and delegation, with enhanced customization and monitoring features to adapt to various operational needs.
|
||||
### 1. **Delegate Work Tool**
|
||||
Allows agents to assign tasks to teammates with specific expertise.
|
||||
|
||||
## Example Scenario
|
||||
```python
|
||||
# Agent automatically gets this tool:
|
||||
# Delegate work to coworker(task: str, context: str, coworker: str)
|
||||
```
|
||||
|
||||
Consider a crew with a researcher agent tasked with data gathering and a writer agent responsible for compiling reports. The integration of advanced language model management and process flow attributes allows for more sophisticated interactions, such as the writer delegating complex research tasks to the researcher or querying specific information, thereby facilitating a seamless workflow.
|
||||
### 2. **Ask Question Tool**
|
||||
Enables agents to ask specific questions to gather information from colleagues.
|
||||
|
||||
## Conclusion
|
||||
```python
|
||||
# Agent automatically gets this tool:
|
||||
# Ask question to coworker(question: str, context: str, coworker: str)
|
||||
```
|
||||
|
||||
The integration of advanced attributes and functionalities into the CrewAI framework significantly enriches the agent collaboration ecosystem. These enhancements not only simplify interactions but also offer unprecedented flexibility and control, paving the way for sophisticated AI-driven solutions capable of tackling complex tasks through intelligent collaboration and delegation.
|
||||
## Collaboration in Action
|
||||
|
||||
Here's a complete example showing agents collaborating on a content creation task:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
|
||||
# Create collaborative agents
|
||||
researcher = Agent(
|
||||
role="Research Specialist",
|
||||
goal="Find accurate, up-to-date information on any topic",
|
||||
backstory="""You're a meticulous researcher with expertise in finding
|
||||
reliable sources and fact-checking information across various domains.""",
|
||||
allow_delegation=True,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
writer = Agent(
|
||||
role="Content Writer",
|
||||
goal="Create engaging, well-structured content",
|
||||
backstory="""You're a skilled content writer who excels at transforming
|
||||
research into compelling, readable content for different audiences.""",
|
||||
allow_delegation=True,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
editor = Agent(
|
||||
role="Content Editor",
|
||||
goal="Ensure content quality and consistency",
|
||||
backstory="""You're an experienced editor with an eye for detail,
|
||||
ensuring content meets high standards for clarity and accuracy.""",
|
||||
allow_delegation=True,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Create a task that encourages collaboration
|
||||
article_task = Task(
|
||||
description="""Write a comprehensive 1000-word article about 'The Future of AI in Healthcare'.
|
||||
|
||||
The article should include:
|
||||
- Current AI applications in healthcare
|
||||
- Emerging trends and technologies
|
||||
- Potential challenges and ethical considerations
|
||||
- Expert predictions for the next 5 years
|
||||
|
||||
Collaborate with your teammates to ensure accuracy and quality.""",
|
||||
expected_output="A well-researched, engaging 1000-word article with proper structure and citations",
|
||||
agent=writer # Writer leads, but can delegate research to researcher
|
||||
)
|
||||
|
||||
# Create collaborative crew
|
||||
crew = Crew(
|
||||
agents=[researcher, writer, editor],
|
||||
tasks=[article_task],
|
||||
process=Process.sequential,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
result = crew.kickoff()
|
||||
```
|
||||
|
||||
## Collaboration Patterns
|
||||
|
||||
### Pattern 1: Research → Write → Edit
|
||||
```python
|
||||
research_task = Task(
|
||||
description="Research the latest developments in quantum computing",
|
||||
expected_output="Comprehensive research summary with key findings and sources",
|
||||
agent=researcher
|
||||
)
|
||||
|
||||
writing_task = Task(
|
||||
description="Write an article based on the research findings",
|
||||
expected_output="Engaging 800-word article about quantum computing",
|
||||
agent=writer,
|
||||
context=[research_task] # Gets research output as context
|
||||
)
|
||||
|
||||
editing_task = Task(
|
||||
description="Edit and polish the article for publication",
|
||||
expected_output="Publication-ready article with improved clarity and flow",
|
||||
agent=editor,
|
||||
context=[writing_task] # Gets article draft as context
|
||||
)
|
||||
```
|
||||
|
||||
### Pattern 2: Collaborative Single Task
|
||||
```python
|
||||
collaborative_task = Task(
|
||||
description="""Create a marketing strategy for a new AI product.
|
||||
|
||||
Writer: Focus on messaging and content strategy
|
||||
Researcher: Provide market analysis and competitor insights
|
||||
|
||||
Work together to create a comprehensive strategy.""",
|
||||
expected_output="Complete marketing strategy with research backing",
|
||||
agent=writer # Lead agent, but can delegate to researcher
|
||||
)
|
||||
```
|
||||
|
||||
## Hierarchical Collaboration
|
||||
|
||||
For complex projects, use a hierarchical process with a manager agent:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
|
||||
# Manager agent coordinates the team
|
||||
manager = Agent(
|
||||
role="Project Manager",
|
||||
goal="Coordinate team efforts and ensure project success",
|
||||
backstory="Experienced project manager skilled at delegation and quality control",
|
||||
allow_delegation=True,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Specialist agents
|
||||
researcher = Agent(
|
||||
role="Researcher",
|
||||
goal="Provide accurate research and analysis",
|
||||
backstory="Expert researcher with deep analytical skills",
|
||||
allow_delegation=False, # Specialists focus on their expertise
|
||||
verbose=True
|
||||
)
|
||||
|
||||
writer = Agent(
|
||||
role="Writer",
|
||||
goal="Create compelling content",
|
||||
backstory="Skilled writer who creates engaging content",
|
||||
allow_delegation=False,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Manager-led task
|
||||
project_task = Task(
|
||||
description="Create a comprehensive market analysis report with recommendations",
|
||||
expected_output="Executive summary, detailed analysis, and strategic recommendations",
|
||||
agent=manager # Manager will delegate to specialists
|
||||
)
|
||||
|
||||
# Hierarchical crew
|
||||
crew = Crew(
|
||||
agents=[manager, researcher, writer],
|
||||
tasks=[project_task],
|
||||
process=Process.hierarchical, # Manager coordinates everything
|
||||
manager_llm="gpt-4o", # Specify LLM for manager
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
## Best Practices for Collaboration
|
||||
|
||||
### 1. **Clear Role Definition**
|
||||
```python
|
||||
# ✅ Good: Specific, complementary roles
|
||||
researcher = Agent(role="Market Research Analyst", ...)
|
||||
writer = Agent(role="Technical Content Writer", ...)
|
||||
|
||||
# ❌ Avoid: Overlapping or vague roles
|
||||
agent1 = Agent(role="General Assistant", ...)
|
||||
agent2 = Agent(role="Helper", ...)
|
||||
```
|
||||
|
||||
### 2. **Strategic Delegation Enabling**
|
||||
```python
|
||||
# ✅ Enable delegation for coordinators and generalists
|
||||
lead_agent = Agent(
|
||||
role="Content Lead",
|
||||
allow_delegation=True, # Can delegate to specialists
|
||||
...
|
||||
)
|
||||
|
||||
# ✅ Disable for focused specialists (optional)
|
||||
specialist_agent = Agent(
|
||||
role="Data Analyst",
|
||||
allow_delegation=False, # Focuses on core expertise
|
||||
...
|
||||
)
|
||||
```
|
||||
|
||||
### 3. **Context Sharing**
|
||||
```python
|
||||
# ✅ Use context parameter for task dependencies
|
||||
writing_task = Task(
|
||||
description="Write article based on research",
|
||||
agent=writer,
|
||||
context=[research_task], # Shares research results
|
||||
...
|
||||
)
|
||||
```
|
||||
|
||||
### 4. **Clear Task Descriptions**
|
||||
```python
|
||||
# ✅ Specific, actionable descriptions
|
||||
Task(
|
||||
description="""Research competitors in the AI chatbot space.
|
||||
Focus on: pricing models, key features, target markets.
|
||||
Provide data in a structured format.""",
|
||||
...
|
||||
)
|
||||
|
||||
# ❌ Vague descriptions that don't guide collaboration
|
||||
Task(description="Do some research about chatbots", ...)
|
||||
```
|
||||
|
||||
## Troubleshooting Collaboration
|
||||
|
||||
### Issue: Agents Not Collaborating
|
||||
**Symptoms:** Agents work in isolation, no delegation occurs
|
||||
```python
|
||||
# ✅ Solution: Ensure delegation is enabled
|
||||
agent = Agent(
|
||||
role="...",
|
||||
allow_delegation=True, # This is required!
|
||||
...
|
||||
)
|
||||
```
|
||||
|
||||
### Issue: Too Much Back-and-Forth
|
||||
**Symptoms:** Agents ask excessive questions, slow progress
|
||||
```python
|
||||
# ✅ Solution: Provide better context and specific roles
|
||||
Task(
|
||||
description="""Write a technical blog post about machine learning.
|
||||
|
||||
Context: Target audience is software developers with basic ML knowledge.
|
||||
Length: 1200 words
|
||||
Include: code examples, practical applications, best practices
|
||||
|
||||
If you need specific technical details, delegate research to the researcher.""",
|
||||
...
|
||||
)
|
||||
```
|
||||
|
||||
### Issue: Delegation Loops
|
||||
**Symptoms:** Agents delegate back and forth indefinitely
|
||||
```python
|
||||
# ✅ Solution: Clear hierarchy and responsibilities
|
||||
manager = Agent(role="Manager", allow_delegation=True)
|
||||
specialist1 = Agent(role="Specialist A", allow_delegation=False) # No re-delegation
|
||||
specialist2 = Agent(role="Specialist B", allow_delegation=False)
|
||||
```
|
||||
|
||||
## Advanced Collaboration Features
|
||||
|
||||
### Custom Collaboration Rules
|
||||
```python
|
||||
# Set specific collaboration guidelines in agent backstory
|
||||
agent = Agent(
|
||||
role="Senior Developer",
|
||||
backstory="""You lead development projects and coordinate with team members.
|
||||
|
||||
Collaboration guidelines:
|
||||
- Delegate research tasks to the Research Analyst
|
||||
- Ask the Designer for UI/UX guidance
|
||||
- Consult the QA Engineer for testing strategies
|
||||
- Only escalate blocking issues to the Project Manager""",
|
||||
allow_delegation=True
|
||||
)
|
||||
```
|
||||
|
||||
### Monitoring Collaboration
|
||||
```python
|
||||
def track_collaboration(output):
|
||||
"""Track collaboration patterns"""
|
||||
if "Delegate work to coworker" in output.raw:
|
||||
print("🤝 Delegation occurred")
|
||||
if "Ask question to coworker" in output.raw:
|
||||
print("❓ Question asked")
|
||||
|
||||
crew = Crew(
|
||||
agents=[...],
|
||||
tasks=[...],
|
||||
step_callback=track_collaboration, # Monitor collaboration
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
## Memory and Learning
|
||||
|
||||
Enable agents to remember past collaborations:
|
||||
|
||||
```python
|
||||
agent = Agent(
|
||||
role="Content Lead",
|
||||
memory=True, # Remembers past interactions
|
||||
allow_delegation=True,
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
With memory enabled, agents learn from previous collaborations and improve their delegation decisions over time.
|
||||
|
||||
## Next Steps
|
||||
|
||||
- **Try the examples**: Start with the basic collaboration example
|
||||
- **Experiment with roles**: Test different agent role combinations
|
||||
- **Monitor interactions**: Use `verbose=True` to see collaboration in action
|
||||
- **Optimize task descriptions**: Clear tasks lead to better collaboration
|
||||
- **Scale up**: Try hierarchical processes for complex projects
|
||||
|
||||
Collaboration transforms individual AI agents into powerful teams that can tackle complex, multi-faceted challenges together.

|
||||
## Creating Crews
|
||||
|
||||
There are two ways to create crews in CrewAI: using **YAML configuration (recommended)** or defining them **directly in code**.
|
||||
|
||||
### YAML Configuration (Recommended)
|
||||
|
||||
Using YAML configuration provides a cleaner, more maintainable way to define crews and is consistent with how agents and tasks are defined in CrewAI projects.
|
||||
|
||||
After creating your CrewAI project as outlined in the [Installation](/installation) section, you can define your crew in a class that inherits from `CrewBase` and uses decorators to define agents, tasks, and the crew itself.
|
||||
|
||||
#### Example Crew Class with Decorators
|
||||
|
||||
```python code
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
from crewai.project import CrewBase, agent, task, crew, before_kickoff, after_kickoff
|
||||
from crewai.agents.agent_builder.base_agent import BaseAgent
|
||||
from typing import List
|
||||

||||
<Note>
|
||||

|
||||
</Note>
|
||||
|
||||
The `CrewBase` class, along with these decorators, automates the collection of agents and tasks, reducing the need for manual management.
|
||||
|
||||
#### Decorators overview from `annotations.py`
|
||||
|
||||
CrewAI provides several decorators in the `annotations.py` file that are used to mark methods within your crew class for special handling:
|
||||
|
||||
- `@CrewBase`: Marks the class as a crew base class.
|
||||
- `@agent`: Denotes a method that returns an `Agent` object.
|
||||
- `@task`: Denotes a method that returns a `Task` object.
|
||||
- `@crew`: Denotes the method that returns the `Crew` object.
|
||||
- `@before_kickoff`: (Optional) Marks a method to be executed before the crew starts.
|
||||
- `@after_kickoff`: (Optional) Marks a method to be executed after the crew finishes.
|
||||
|
||||
These decorators help in organizing your crew's structure and automatically collecting agents and tasks without manually listing them.
|
||||
|
||||
### Direct Code Definition (Alternative)
|
||||
|
||||
Alternatively, you can define the crew directly in code without using YAML configuration files.
|
||||
|
||||
```python code
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
from crewai_tools import YourCustomTool
|
||||
|
||||
class YourCrewName:
|
||||
def agent_one(self) -> Agent:
|
||||
return Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze data trends in the market",
|
||||
backstory="An experienced data analyst with a background in economics",
|
||||
verbose=True,
|
||||
tools=[YourCustomTool()]
|
||||
)
|
||||
|
||||
def agent_two(self) -> Agent:
|
||||
return Agent(
|
||||
role="Market Researcher",
|
||||
goal="Gather information on market dynamics",
|
||||
backstory="A diligent researcher with a keen eye for detail",
|
||||
verbose=True
|
||||
)
|
||||
|
||||
def task_one(self) -> Task:
|
||||
return Task(
|
||||
description="Collect recent market data and identify trends.",
|
||||
expected_output="A report summarizing key trends in the market.",
|
||||
agent=self.agent_one()
|
||||
)
|
||||
|
||||
def task_two(self) -> Task:
|
||||
return Task(
|
||||
description="Research factors affecting market dynamics.",
|
||||
expected_output="An analysis of factors influencing the market.",
|
||||
agent=self.agent_two()
|
||||
)
|
||||
|
||||
def crew(self) -> Crew:
|
||||
return Crew(
|
||||
agents=[self.agent_one(), self.agent_two()],
|
||||
tasks=[self.task_one(), self.task_two()],
|
||||
process=Process.sequential,
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
How to run the above code:
|
||||
|
||||
```python code
|
||||
YourCrewName().crew().kickoff(inputs={})
|
||||
```
|
||||
|
||||
In this example:
|
||||
|
||||
- Agents and tasks are defined directly within the class without decorators.
|
||||
- We manually create and manage the list of agents and tasks.
|
||||
- This approach provides more control but can be less maintainable for larger projects.

## Accessing Crew Logs
|

|
||||
|
||||
## Overview
|
||||
|
||||
CrewAI provides a powerful event system that allows you to listen for and react to various events that occur during the execution of your Crew. This feature enables you to build custom integrations, monitoring solutions, logging systems, or any other functionality that needs to be triggered based on CrewAI's internal events.
|
||||
|
||||
## How It Works
|
||||
|
||||
CrewAI uses an event bus architecture to emit events throughout the execution lifecycle. The event system is built on the following components:
|
||||
|
||||
1. **CrewAIEventsBus**: A singleton event bus that manages event registration and emission
|
||||
2. **BaseEvent**: Base class for all events in the system
|
||||
3. **BaseEventListener**: Abstract base class for creating custom event listeners
|
||||
|
||||
When specific actions occur in CrewAI (like a Crew starting execution, an Agent completing a task, or a tool being used), the system emits corresponding events. You can register handlers for these events to execute custom code when they occur.
|
||||
|
||||
<Note type="info" title="Enterprise Enhancement: Prompt Tracing">
|
||||
CrewAI Enterprise provides a built-in Prompt Tracing feature that leverages the event system to track, store, and visualize all prompts, completions, and associated metadata. This provides powerful debugging capabilities and transparency into your agent operations.
|
||||
|
||||

|
||||
|
||||
With Prompt Tracing you can:
|
||||
- View the complete history of all prompts sent to your LLM
|
||||
- Track token usage and costs
|
||||
- Debug agent reasoning failures
|
||||
- Share prompt sequences with your team
|
||||
- Compare different prompt strategies
|
||||
- Export traces for compliance and auditing
|
||||
</Note>
|
||||
|
||||
## Creating a Custom Event Listener
|
||||
|
||||
To create a custom event listener, you need to:
|
||||
|
||||
1. Create a class that inherits from `BaseEventListener`
|
||||
2. Implement the `setup_listeners` method
|
||||
3. Register handlers for the events you're interested in
|
||||
4. Create an instance of your listener in the appropriate file
|
||||
|
||||
Here's a simple example of a custom event listener class:
|
||||
|
||||
```python
|
||||
from crewai.utilities.events import (
|
||||
CrewKickoffStartedEvent,
|
||||
CrewKickoffCompletedEvent,
|
||||
AgentExecutionCompletedEvent,
|
||||
)
|
||||
from crewai.utilities.events.base_event_listener import BaseEventListener
|
||||
|
||||
class MyCustomListener(BaseEventListener):
|
||||
def __init__(self):
|
||||
super().__init__()
|
||||
|
||||
def setup_listeners(self, crewai_event_bus):
|
||||
@crewai_event_bus.on(CrewKickoffStartedEvent)
|
||||
def on_crew_started(source, event):
|
||||
print(f"Crew '{event.crew_name}' has started execution!")
|
||||
|
||||
@crewai_event_bus.on(CrewKickoffCompletedEvent)
|
||||
def on_crew_completed(source, event):
|
||||
print(f"Crew '{event.crew_name}' has completed execution!")
|
||||
print(f"Output: {event.output}")
|
||||
|
||||
@crewai_event_bus.on(AgentExecutionCompletedEvent)
|
||||
def on_agent_execution_completed(source, event):
|
||||
print(f"Agent '{event.agent.role}' completed task")
|
||||
print(f"Output: {event.output}")
|
||||
```
|
||||
|
||||
## Properly Registering Your Listener
|
||||
|
||||
Simply defining your listener class isn't enough. You need to create an instance of it and ensure it's imported in your application. This ensures that:
|
||||
|
||||
1. The event handlers are registered with the event bus
|
||||
2. The listener instance remains in memory (not garbage collected)
|
||||
3. The listener is active when events are emitted
|
||||
|
||||
### Option 1: Import and Instantiate in Your Crew or Flow Implementation
|
||||
|
||||
The most important thing is to create an instance of your listener in the file where your Crew or Flow is defined and executed:
|
||||
|
||||
#### For Crew-based Applications
|
||||
|
||||
Create and import your listener at the top of your Crew implementation file:
|
||||
|
||||
```python
|
||||
# In your crew.py file
|
||||
from crewai import Agent, Crew, Task
|
||||
from my_listeners import MyCustomListener
|
||||
|
||||
# Create an instance of your listener
|
||||
my_listener = MyCustomListener()
|
||||
|
||||
class MyCustomCrew:
|
||||
# Your crew implementation...
|
||||
|
||||
def crew(self):
|
||||
return Crew(
|
||||
agents=[...],
|
||||
tasks=[...],
|
||||
# ...
|
||||
)
|
||||
```
|
||||
|
||||
#### For Flow-based Applications
|
||||
|
||||
Create and import your listener at the top of your Flow implementation file:
|
||||
|
||||
```python
|
||||
# In your main.py or flow.py file
|
||||
from crewai.flow import Flow, listen, start
|
||||
from my_listeners import MyCustomListener
|
||||
|
||||
# Create an instance of your listener
|
||||
my_listener = MyCustomListener()
|
||||
|
||||
class MyCustomFlow(Flow):
|
||||
# Your flow implementation...
|
||||
|
||||
@start()
|
||||
def first_step(self):
|
||||
# ...
|
||||
```
|
||||
|
||||
This ensures that your listener is loaded and active when your Crew or Flow is executed.
|
||||
|
||||
### Option 2: Create a Package for Your Listeners
|
||||
|
||||
For a more structured approach, especially if you have multiple listeners:
|
||||
|
||||
1. Create a package for your listeners:
|
||||
|
||||
```
|
||||
my_project/
|
||||
├── listeners/
|
||||
│ ├── __init__.py
|
||||
│ ├── my_custom_listener.py
|
||||
│ └── another_listener.py
|
||||
```
|
||||
|
||||
2. In `my_custom_listener.py`, define your listener class and create an instance:
|
||||
|
||||
```python
|
||||
# my_custom_listener.py
|
||||
from crewai.utilities.events.base_event_listener import BaseEventListener
|
||||
# ... import events ...
|
||||
|
||||
class MyCustomListener(BaseEventListener):
|
||||
# ... implementation ...
|
||||
|
||||
# Create an instance of your listener
|
||||
my_custom_listener = MyCustomListener()
|
||||
```
|
||||
|
||||
3. In `__init__.py`, import the listener instances to ensure they're loaded:
|
||||
|
||||
```python
|
||||
# __init__.py
|
||||
from .my_custom_listener import my_custom_listener
|
||||
from .another_listener import another_listener
|
||||
|
||||
# Optionally export them if you need to access them elsewhere
|
||||
__all__ = ['my_custom_listener', 'another_listener']
|
||||
```
|
||||
|
||||
4. Import your listeners package in your Crew or Flow file:
|
||||
|
||||
```python
|
||||
# In your crew.py or flow.py file
|
||||
import my_project.listeners # This loads all your listeners
|
||||
|
||||
class MyCustomCrew:
|
||||
# Your crew implementation...
|
||||
```
|
||||
|
||||
This is exactly how CrewAI's built-in `agentops_listener` is registered. In the CrewAI codebase, you'll find:
|
||||
|
||||
```python
|
||||
# src/crewai/utilities/events/third_party/__init__.py
|
||||
from .agentops_listener import agentops_listener
|
||||
```
|
||||
|
||||
This ensures the `agentops_listener` is loaded when the `crewai.utilities.events` package is imported.
|
||||
|
||||
## Available Event Types

|
||||
|
||||
## Event Handler Structure
|
||||
|
||||
Each event handler receives two parameters:
|
||||
|
||||
1. **source**: The object that emitted the event
|
||||
2. **event**: The event instance, containing event-specific data
|
||||
|
||||
The structure of the event object depends on the event type, but all events inherit from `BaseEvent` and include:
|
||||
|
||||
- **timestamp**: The time when the event was emitted
|
||||
- **type**: A string identifier for the event type
|
||||
|
||||
Additional fields vary by event type. For example, `CrewKickoffCompletedEvent` includes `crew_name` and `output` fields.
|
||||
|
||||

|
||||
```
|
||||
|
||||
This listener initializes an AgentOps session when a Crew starts, registers agents with AgentOps, tracks tool usage, and ends the session when the Crew completes.
|
||||
|
||||
The AgentOps listener is registered in CrewAI's event system through the import in `src/crewai/utilities/events/third_party/__init__.py`:
|
||||
|
||||
```python
|
||||
from .agentops_listener import agentops_listener
|
||||
```
|
||||
|
||||
This ensures the `agentops_listener` is loaded when the `crewai.utilities.events` package is imported.
|
||||
|
||||
## Advanced Usage: Scoped Handlers
|
||||
|
||||
For temporary event handling (useful for testing or specific operations), you can use the `scoped_handlers` context manager:
|
||||
|
||||
```python
|
||||
from crewai.utilities.events import crewai_event_bus, CrewKickoffStartedEvent
|
||||
|
||||
with crewai_event_bus.scoped_handlers():
|
||||
@crewai_event_bus.on(CrewKickoffStartedEvent)
|
||||
def temp_handler(source, event):
|
||||
print("This handler only exists within this context")
|
||||
|
||||
# Do something that emits events
|
||||
|
||||
# Outside the context, the temporary handler is removed
|
||||
```
|
||||
|
||||
## Use Cases
|
||||
|
||||
Event listeners can be used for a variety of purposes:
|
||||
|
||||
1. **Logging and Monitoring**: Track the execution of your Crew and log important events
|
||||
2. **Analytics**: Collect data about your Crew's performance and behavior
|
||||
3. **Debugging**: Set up temporary listeners to debug specific issues
|
||||
4. **Integration**: Connect CrewAI with external systems like monitoring platforms, databases, or notification services
|
||||
5. **Custom Behavior**: Trigger custom actions based on specific events
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Keep Handlers Light**: Event handlers should be lightweight and avoid blocking operations
|
||||
2. **Error Handling**: Include proper error handling in your event handlers to prevent exceptions from affecting the main execution
|
||||
3. **Cleanup**: If your listener allocates resources, ensure they're properly cleaned up
|
||||
4. **Selective Listening**: Only listen for events you actually need to handle
|
||||
5. **Testing**: Test your event listeners in isolation to ensure they behave as expected
|
||||
|
||||
By leveraging CrewAI's event system, you can extend its functionality and integrate it seamlessly with your existing infrastructure.

|
||||
|
||||

|
||||
In the above example, we have created a simple Flow that generates a random city using OpenAI and then generates a fun fact about that city. The Flow consists of two tasks: `generate_city` and `generate_fun_fact`. The `generate_city` task is the starting point of the Flow, and the `generate_fun_fact` task listens for the output of the `generate_city` task.
|
||||
|
||||
When you run the Flow, it will generate a random city and then generate a fun fact about that city. The output will be printed to the console.
|
||||
Each Flow instance automatically receives a unique identifier (UUID) in its state, which helps track and manage flow executions. The state can also store additional data (like the generated city and fun fact) that persists throughout the flow's execution.
|
||||
|
||||
When you run the Flow, it will:
|
||||
1. Generate a unique ID for the flow state
|
||||
2. Generate a random city and store it in the state
|
||||
3. Generate a fun fact about that city and store it in the state
|
||||
4. Print the results to the console
|
||||
|
||||
The state's unique ID and stored data can be useful for tracking flow executions and maintaining context between tasks.
|
||||
|
||||
**Note:** Ensure you have set up your `.env` file to store your `OPENAI_API_KEY`. This key is necessary for authenticating requests to the OpenAI API.

By providing both unstructured and structured state management options, CrewAI Flows empowers developers to build AI workflows that are both flexible and robust, catering to a wide range of application requirements.
|
||||
|
||||
## Flow Persistence
|
||||
|
||||
The @persist decorator enables automatic state persistence in CrewAI Flows, allowing you to maintain flow state across restarts or different workflow executions. This decorator can be applied at either the class level or method level, providing flexibility in how you manage state persistence.
|
||||
|
||||
### Class-Level Persistence
|
||||
|
||||
When applied at the class level, the @persist decorator automatically persists all flow method states:
|
||||
|
||||
```python
|
||||
@persist # Using SQLiteFlowPersistence by default
|
||||
class MyFlow(Flow[MyState]):
|
||||
@start()
|
||||
def initialize_flow(self):
|
||||
# This method will automatically have its state persisted
|
||||
self.state.counter = 1
|
||||
print("Initialized flow. State ID:", self.state.id)
|
||||
|
||||
@listen(initialize_flow)
|
||||
def next_step(self):
|
||||
# The state (including self.state.id) is automatically reloaded
|
||||
self.state.counter += 1
|
||||
print("Flow state is persisted. Counter:", self.state.counter)
|
||||
```
|
||||
|
||||
### Method-Level Persistence
|
||||
|
||||
For more granular control, you can apply @persist to specific methods:
|
||||
|
||||
```python
|
||||
class AnotherFlow(Flow[dict]):
|
||||
@persist # Persists only this method's state
|
||||
@start()
|
||||
def begin(self):
|
||||
if "runs" not in self.state:
|
||||
self.state["runs"] = 0
|
||||
self.state["runs"] += 1
|
||||
print("Method-level persisted runs:", self.state["runs"])
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Unique State Identification**
|
||||
- Each flow state automatically receives a unique UUID
|
||||
- The ID is preserved across state updates and method calls
|
||||
- Supports both structured (Pydantic BaseModel) and unstructured (dictionary) states
|
||||
|
||||
2. **Default SQLite Backend**
|
||||
- SQLiteFlowPersistence is the default storage backend
|
||||
- States are automatically saved to a local SQLite database
|
||||
- Robust error handling ensures clear messages if database operations fail
|
||||
|
||||
3. **Error Handling**
|
||||
- Comprehensive error messages for database operations
|
||||
- Automatic state validation during save and load
|
||||
- Clear feedback when persistence operations encounter issues
|
||||
|
||||
### Important Considerations
|
||||
|
||||
- **State Types**: Both structured (Pydantic BaseModel) and unstructured (dictionary) states are supported
|
||||
- **Automatic ID**: The `id` field is automatically added if not present
|
||||
- **State Recovery**: Failed or restarted flows can automatically reload their previous state
|
||||
- **Custom Implementation**: You can provide your own FlowPersistence implementation for specialized storage needs
|
||||
|
||||
### Technical Advantages
|
||||
|
||||
1. **Precise Control Through Low-Level Access**
|
||||
- Direct access to persistence operations for advanced use cases
|
||||
- Fine-grained control via method-level persistence decorators
|
||||
- Built-in state inspection and debugging capabilities
|
||||
- Full visibility into state changes and persistence operations
|
||||
|
||||
2. **Enhanced Reliability**
|
||||
- Automatic state recovery after system failures or restarts
|
||||
- Transaction-based state updates for data integrity
|
||||
- Comprehensive error handling with clear error messages
|
||||
- Robust validation during state save and load operations
|
||||
|
||||
3. **Extensible Architecture**
|
||||
- Customizable persistence backend through FlowPersistence interface
|
||||
- Support for specialized storage solutions beyond SQLite
|
||||
- Compatible with both structured (Pydantic) and unstructured (dict) states
|
||||
- Seamless integration with existing CrewAI flow patterns
|
||||
|
||||
The persistence system's architecture emphasizes technical precision and customization options, allowing developers to maintain full control over state management while benefiting from built-in reliability features.

This example demonstrates several key features of using Agents in flows:
|
||||
|
||||
1. **Structured Output**: Using Pydantic models to define the expected output format (`MarketAnalysis`) ensures type safety and structured data throughout the flow.
|
||||
|
||||
2. **State Management**: The flow state (`MarketResearchState`) maintains context between steps and stores both inputs and outputs.
|
||||
|
||||
3. **Tool Integration**: Agents can use tools (like `WebsiteSearchTool`) to enhance their capabilities.

### Adding Additional Crews Using the CLI
|
||||
|
||||
Once you have created your initial flow, you can easily add additional crews to your project using the CLI. This allows you to expand your flow's capabilities by integrating new crews without starting from scratch.
|
||||
|
||||
To add a new crew to your existing flow, use the following command:
|
||||
|
||||
```bash
|
||||
crewai flow add-crew <crew_name>
|
||||
```
|
||||
|
||||
This command will create a new directory for your crew within the `crews` folder of your flow project. It will include the necessary configuration files and a crew definition file, similar to the initial setup.
|
||||
|
||||
#### Folder Structure
|
||||
|
||||
After adding a new crew, your folder structure will look like this:
|
||||
|
||||
name_of_flow/
|
||||
├── crews/
|
||||
│ ├── poem_crew/
|
||||
│ │ ├── config/
|
||||
│ │ │ ├── agents.yaml
|
||||
│ │ │ └── tasks.yaml
|
||||
│ │ └── poem_crew.py
|
||||
│ └── name_of_crew/
|
||||
│ ├── config/
|
||||
│ │ ├── agents.yaml
|
||||
│ │ └── tasks.yaml
|
||||
│ └── name_of_crew.py
|
||||
|
||||
You can then customize the `agents.yaml` and `tasks.yaml` files to define the agents and tasks for your new crew. The `name_of_crew.py` file will contain the crew's logic, which you can modify to suit your needs.
|
||||
|
||||
By using the CLI to add additional crews, you can efficiently build complex AI workflows that leverage multiple crews working together.

### Conclusion
|
||||
|
||||
## Advanced
|
||||
|
||||
In this section, we explore more complex use cases of CrewAI Flows, starting with a self-evaluation loop. This pattern is crucial for developing AI systems that can iteratively improve their outputs through feedback.
|
||||
|
||||
### 1) Self-Evaluation Loop
|
||||
|
||||
The self-evaluation loop is a powerful pattern that allows AI workflows to automatically assess and refine their outputs. This example demonstrates how to set up a flow that generates content, evaluates it, and iterates based on feedback until the desired quality is achieved.
|
||||
|
||||
#### Overview
|
||||
|
||||
The self-evaluation loop involves two main Crews:
|
||||
|
||||
1. **ShakespeareanXPostCrew**: Generates a Shakespearean-style post on a given topic.
|
||||
2. **XPostReviewCrew**: Evaluates the generated post, providing feedback on its validity and quality.
|
||||
|
||||
The process iterates until the post meets the criteria or a maximum retry limit is reached. This approach ensures high-quality outputs through iterative refinement.
|
||||
|
||||
#### Importance
|
||||
|
||||
This pattern is essential for building robust AI systems that can adapt and improve over time. By automating the evaluation and feedback loop, developers can ensure that their AI workflows produce reliable and high-quality results.
|
||||
|
||||
#### Main Code Highlights
|
||||
|
||||
Below is the `main.py` file for the self-evaluation loop flow:
|
||||
|
||||
```python

|
||||

|
||||

|
||||
|
||||
#### Code Highlights
|
||||
|
||||
- **Retry Mechanism**: The flow uses a retry mechanism to regenerate the post if it doesn't meet the criteria, up to a maximum of three retries.
|
||||
- **Feedback Loop**: Feedback from the `XPostReviewCrew` is used to refine the post iteratively.
|
||||
- **State Management**: The flow maintains state using a Pydantic model, ensuring type safety and clarity.

## Running Flows
|
||||
|
||||
There are two ways to run a flow:
|
||||
|
||||
### Using the Flow API
|
||||
|
||||
You can run a flow programmatically by creating an instance of your flow class and calling the `kickoff()` method:
|
||||
|
||||
```python
|
||||
flow = ExampleFlow()
|
||||
result = flow.kickoff()
|
||||
```
|
||||
|
||||
### Using the CLI
|
||||
|
||||
Starting from version 0.103.0, you can run flows using the `crewai run` command:
|
||||
|
||||
```shell
|
||||
crewai run
|
||||
```
|
||||
|
||||
This command automatically detects if your project is a flow (based on the `type = "flow"` setting in your pyproject.toml) and runs it accordingly. This is the recommended way to run flows from the command line.
|
||||
|
||||
For backward compatibility, you can also use:
|
||||
|
||||
```shell
|
||||
crewai flow kickoff
|
||||
```
|
||||
|
||||
However, the `crewai run` command is now the preferred method as it works for both crews and flows.

|
||||
## Overview
|
||||
|
||||
Agent reasoning is a feature that allows agents to reflect on a task and create a plan before execution. This helps agents approach tasks more methodically and ensures they're ready to perform the assigned work.
|
||||
|
||||
## Usage
|
||||
|
||||
To enable reasoning for an agent, simply set `reasoning=True` when creating the agent:
|
||||
|
||||
```python
|
||||
from crewai import Agent
|
||||
|
||||
agent = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze complex datasets and provide insights",
|
||||
backstory="You are an experienced data analyst with expertise in finding patterns in complex data.",
|
||||
reasoning=True, # Enable reasoning
|
||||
max_reasoning_attempts=3 # Optional: Set a maximum number of reasoning attempts
|
||||
)
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
When reasoning is enabled, before executing a task, the agent will:
|
||||
|
||||
1. Reflect on the task and create a detailed plan
|
||||
2. Evaluate whether it's ready to execute the task
|
||||
3. Refine the plan as necessary until it's ready or max_reasoning_attempts is reached
|
||||
4. Inject the reasoning plan into the task description before execution
|
||||
|
||||
This process helps the agent break down complex tasks into manageable steps and identify potential challenges before starting.
|
||||
|
||||
## Configuration Options
|
||||
|
||||
<ParamField body="reasoning" type="bool" default="False">
|
||||
Enable or disable reasoning
|
||||
</ParamField>
|
||||
|
||||
<ParamField body="max_reasoning_attempts" type="int" default="None">
|
||||
Maximum number of attempts to refine the plan before proceeding with execution. If None (default), the agent will continue refining until it's ready.
|
||||
</ParamField>
|
||||
|
||||
## Example
|
||||
|
||||
Here's a complete example:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Task, Crew
|
||||
|
||||
# Create an agent with reasoning enabled
|
||||
analyst = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze data and provide insights",
|
||||
backstory="You are an expert data analyst.",
|
||||
reasoning=True,
|
||||
max_reasoning_attempts=3 # Optional: Set a limit on reasoning attempts
|
||||
)
|
||||
|
||||
# Create a task
|
||||
analysis_task = Task(
|
||||
description="Analyze the provided sales data and identify key trends.",
|
||||
expected_output="A report highlighting the top 3 sales trends.",
|
||||
agent=analyst
|
||||
)
|
||||
|
||||
# Create a crew and run the task
|
||||
crew = Crew(agents=[analyst], tasks=[analysis_task])
|
||||
result = crew.kickoff()
|
||||
|
||||
print(result)
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The reasoning process is designed to be robust, with error handling built in. If an error occurs during reasoning, the agent will proceed with executing the task without the reasoning plan. This ensures that tasks can still be executed even if the reasoning process fails.
|
||||
|
||||
Here's how to handle potential errors in your code:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Task
|
||||
import logging
|
||||
|
||||
# Set up logging to capture any reasoning errors
|
||||
logging.basicConfig(level=logging.INFO)
|
||||
|
||||
# Create an agent with reasoning enabled
|
||||
agent = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze data and provide insights",
|
||||
reasoning=True,
|
||||
max_reasoning_attempts=3
|
||||
)
|
||||
|
||||
# Create a task
|
||||
task = Task(
|
||||
description="Analyze the provided sales data and identify key trends.",
|
||||
expected_output="A report highlighting the top 3 sales trends.",
|
||||
agent=agent
|
||||
)
|
||||
|
||||
# Execute the task
|
||||
# If an error occurs during reasoning, it will be logged and execution will continue
|
||||
result = agent.execute_task(task)
|
||||
```
|
||||
|
||||
## Example Reasoning Output
|
||||
|
||||
Here's an example of what a reasoning plan might look like for a data analysis task:
|
||||
|
||||
```
|
||||
Task: Analyze the provided sales data and identify key trends.
|
||||
|
||||
Reasoning Plan:
|
||||
I'll analyze the sales data to identify the top 3 trends.
|
||||
|
||||
1. Understanding of the task:
|
||||
I need to analyze sales data to identify key trends that would be valuable for business decision-making.
|
||||
|
||||
2. Key steps I'll take:
|
||||
- First, I'll examine the data structure to understand what fields are available
|
||||
- Then I'll perform exploratory data analysis to identify patterns
|
||||
- Next, I'll analyze sales by time periods to identify temporal trends
|
||||
- I'll also analyze sales by product categories and customer segments
|
||||
- Finally, I'll identify the top 3 most significant trends
|
||||
|
||||
3. Approach to challenges:
|
||||
- If the data has missing values, I'll decide whether to fill or filter them
|
||||
- If the data has outliers, I'll investigate whether they're valid data points or errors
|
||||
- If trends aren't immediately obvious, I'll apply statistical methods to uncover patterns
|
||||
|
||||
4. Use of available tools:
|
||||
- I'll use data analysis tools to explore and visualize the data
|
||||
- I'll use statistical tools to identify significant patterns
|
||||
- I'll use knowledge retrieval to access relevant information about sales analysis
|
||||
|
||||
5. Expected outcome:
|
||||
A concise report highlighting the top 3 sales trends with supporting evidence from the data.
|
||||
|
||||
READY: I am ready to execute the task.
|
||||
```
|
||||
|
||||
This reasoning plan helps the agent organize its approach to the task, consider potential challenges, and ensure it delivers the expected output.

## Overview of a Task
|
||||
## Overview
|
||||
|
||||
In the CrewAI framework, a `Task` is a specific assignment completed by an `Agent`.
|
||||
|
||||
They provide all necessary details for execution, such as a description, the agent responsible, required tools, and more, facilitating a wide range of action complexities.

In the CrewAI framework, a `Task` is a specific assignment completed by an `Agent`.
|
||||
|
||||
Tasks provide all necessary details for execution, such as a description, the agent responsible, required tools, and more, facilitating a wide range of action complexities.
|
||||
|
||||
Tasks within CrewAI can be collaborative, requiring multiple agents to work together. This is managed through the task properties and orchestrated by the Crew's process, enhancing teamwork and efficiency.
|
||||
|
||||
<Note type="info" title="Enterprise Enhancement: Visual Task Builder">
|
||||
CrewAI Enterprise includes a Visual Task Builder in Crew Studio that simplifies complex task creation and chaining. Design your task flows visually and test them in real-time without writing code.
|
||||
|
||||

|
||||
|
||||
The Visual Task Builder enables:
|
||||
- Drag-and-drop task creation
|
||||
- Visual task dependencies and flow
|
||||
- Real-time testing and validation
|
||||
- Easy sharing and collaboration
|
||||
</Note>
|
||||
|
||||
### Task Execution Flow
|
||||
|
||||
Tasks can be executed in two ways:
|
||||
- **Sequential**: Tasks are executed in the order they are defined
|
||||
- **Hierarchical**: Tasks are assigned to agents based on their roles and expertise
|
||||
|
||||
The execution flow is defined when creating the crew:
|
||||
```python Code
|
||||
crew = Crew(
|
||||
agents=[agent1, agent2],
|
||||
tasks=[task1, task2],
|
||||
process=Process.sequential # or Process.hierarchical
|
||||
)
|
||||
```
|
||||
|
||||

## Creating a Task
|
||||
## Creating Tasks
|
||||
|
||||
Creating a task involves defining its scope, responsible agent, and any additional attributes for flexibility:
|
||||
There are two ways to create tasks in CrewAI: using **YAML configuration (recommended)** or defining them **directly in code**.
|
||||
|
||||
### YAML Configuration (Recommended)
|
||||
|
||||
Using YAML configuration provides a cleaner, more maintainable way to define tasks. We strongly recommend using this approach to define tasks in your CrewAI projects.
|
||||
|
||||
After creating your CrewAI project as outlined in the [Installation](/installation) section, navigate to the `src/latest_ai_development/config/tasks.yaml` file and modify the template to match your specific task requirements.
|
||||
|
||||
<Note>
|
||||
Variables in your YAML files (like `{topic}`) will be replaced with values from your inputs when running the crew:
|
||||
```python Code
|
||||
crew.kickoff(inputs={'topic': 'AI Agents'})
|
||||
```
|
||||
</Note>
|
||||
|
||||
Here's an example of how to configure tasks using YAML:
|
||||
|
||||
```yaml tasks.yaml
|
||||
research_task:
|
||||
description: >
|
||||
Conduct a thorough research about {topic}
|
||||
Make sure you find any interesting and relevant information given
|
||||
the current year is 2025.
|
||||
expected_output: >
|
||||
A list with 10 bullet points of the most relevant information about {topic}
|
||||
agent: researcher
|
||||
|
||||
reporting_task:
|
||||
description: >
|
||||
Review the context you got and expand each topic into a full section for a report.
|
||||
Make sure the report is detailed and contains any and all relevant information.
|
||||
expected_output: >
|
||||
A fully fledge reports with the mains topics, each with a full section of information.
|
||||
Formatted as markdown without '```'
|
||||
agent: reporting_analyst
|
||||
markdown: true
|
||||
output_file: report.md
|
||||
```
|
||||
|
||||
To use this YAML configuration in your code, create a crew class that inherits from `CrewBase`:
|
||||
|
||||
```python crew.py
|
||||
# src/latest_ai_development/crew.py
|
||||
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from crewai.project import CrewBase, agent, crew, task
|
||||
from crewai_tools import SerperDevTool
|
||||
|
||||
@CrewBase
|
||||
class LatestAiDevelopmentCrew():

|
||||
def researcher(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['researcher'], # type: ignore[index]
|
||||

|
||||

|
||||
)
|
||||
|
||||
@agent
|
||||
def reporting_analyst(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['reporting_analyst'], # type: ignore[index]
|
||||
verbose=True
|
||||
)
|
||||
|
||||
@task
|
||||
def research_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['research_task'] # type: ignore[index]
|
||||
)
|
||||
|
||||
@task
|
||||
def reporting_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['reporting_task'] # type: ignore[index]
|
||||
)
|
||||
|
||||
@crew
|
||||
def crew(self) -> Crew:
|
||||
return Crew(
|
||||
agents=[
|
||||
self.researcher(),
|
||||
self.reporting_analyst()
|
||||
],
|
||||
tasks=[
|
||||
self.research_task(),
|
||||
self.reporting_task()
|
||||
],
|
||||
process=Process.sequential
|
||||
)
|
||||
```
|
||||
|
||||
<Note>
|
||||
The names you use in your YAML files (`agents.yaml` and `tasks.yaml`) should match the method names in your Python code.
|
||||
</Note>
|
||||
|
||||
### Direct Code Definition (Alternative)
|
||||
|
||||
Alternatively, you can define tasks directly in your code without using YAML configuration:
|
||||
|
||||
```python task.py
|
||||
from crewai import Task
|
||||
|
||||

## Task Output
|
||||
|
||||
Understanding task outputs is crucial for building effective AI workflows. CrewAI provides a structured way to handle task results through the `TaskOutput` class, which supports multiple output formats and can be easily passed between tasks.
|
||||
|
||||
The output of a task in CrewAI framework is encapsulated within the `TaskOutput` class. This class provides a structured way to access results of a task, including various formats such as raw output, JSON, and Pydantic models.
|
||||
|
||||
By default, the `TaskOutput` will only include the `raw` output. A `TaskOutput` will only include the `pydantic` or `json_dict` output if the original `Task` object was configured with `output_pydantic` or `output_json`, respectively.
|
||||
@@ -112,6 +259,361 @@ if task_output.pydantic:
|
||||
print(f"Pydantic Output: {task_output.pydantic}")
|
||||
```
|
||||
|
||||
## Markdown Output Formatting
|
||||
|
||||
The `markdown` parameter enables automatic markdown formatting for task outputs. When set to `True`, the task will instruct the agent to format the final answer using proper Markdown syntax.
|
||||
|
||||
### Using Markdown Formatting
|
||||
|
||||
```python Code
|
||||
# Example task with markdown formatting enabled
|
||||
formatted_task = Task(
|
||||
description="Create a comprehensive report on AI trends",
|
||||
expected_output="A well-structured report with headers, sections, and bullet points",
|
||||
agent=reporter_agent,
|
||||
markdown=True # Enable automatic markdown formatting
|
||||
)
|
||||
```
|
||||
|
||||
When `markdown=True`, the agent will receive additional instructions to format the output using:
|
||||
- `#` for headers
|
||||
- `**text**` for bold text
|
||||
- `*text*` for italic text
|
||||
- `-` or `*` for bullet points
|
||||
- `` `code` `` for inline code
|
||||
- ``` ```language ``` for code blocks
|
||||
|
||||
### YAML Configuration with Markdown
|
||||
|
||||
```yaml tasks.yaml
|
||||
analysis_task:
|
||||
description: >
|
||||
Analyze the market data and create a detailed report
|
||||
expected_output: >
|
||||
A comprehensive analysis with charts and key findings
|
||||
agent: analyst
|
||||
markdown: true # Enable markdown formatting
|
||||
output_file: analysis.md
|
||||
```
|
||||
|
||||
### Benefits of Markdown Output
|
||||
|
||||
- **Consistent Formatting**: Ensures all outputs follow proper markdown conventions
|
||||
- **Better Readability**: Structured content with headers, lists, and emphasis
|
||||
- **Documentation Ready**: Output can be directly used in documentation systems
|
||||
- **Cross-Platform Compatibility**: Markdown is universally supported
|
||||
|
||||
<Note>
|
||||
The markdown formatting instructions are automatically added to the task prompt when `markdown=True`, so you don't need to specify formatting requirements in your task description.
|
||||
</Note>
|
||||
|
||||
## Task Dependencies and Context
|
||||
|
||||
Tasks can depend on the output of other tasks using the `context` attribute. For example:
|
||||
|
||||
```python Code
|
||||
research_task = Task(
|
||||
description="Research the latest developments in AI",
|
||||
expected_output="A list of recent AI developments",
|
||||
agent=researcher
|
||||
)
|
||||
|
||||
analysis_task = Task(
|
||||
description="Analyze the research findings and identify key trends",
|
||||
expected_output="Analysis report of AI trends",
|
||||
agent=analyst,
|
||||
context=[research_task] # This task will wait for research_task to complete
|
||||
)
|
||||
```
|
||||
|
||||
## Task Guardrails
|
||||
|
||||
Task guardrails provide a way to validate and transform task outputs before they
|
||||
are passed to the next task. This feature helps ensure data quality and provides
|
||||
feedback to agents when their output doesn't meet specific criteria.
|
||||
|
||||
### Using Task Guardrails
|
||||
|
||||
To add a guardrail to a task, provide a validation function through the `guardrail` parameter:
|
||||
|
||||
```python Code
|
||||
from typing import Tuple, Union, Dict, Any
|
||||
from crewai import TaskOutput
|
||||
|
||||
def validate_blog_content(result: TaskOutput) -> Tuple[bool, Any]:
|
||||
"""Validate blog content meets requirements."""
|
||||
try:
|
||||
# Check word count
|
||||
word_count = len(result.split())
|
||||
if word_count > 200:
|
||||
return (False, "Blog content exceeds 200 words")
|
||||
|
||||
# Additional validation logic here
|
||||
return (True, result.strip())
|
||||
except Exception as e:
|
||||
return (False, "Unexpected error during validation")
|
||||
|
||||
blog_task = Task(
|
||||
description="Write a blog post about AI",
|
||||
expected_output="A blog post under 200 words",
|
||||
agent=blog_agent,
|
||||
guardrail=validate_blog_content # Add the guardrail function
|
||||
)
|
||||
```
|
||||
|
||||
### Guardrail Function Requirements
|
||||
|
||||
1. **Function Signature**:
|
||||
- Must accept exactly one parameter (the task output)
|
||||
- Should return a tuple of `(bool, Any)`
|
||||
- Type hints are recommended but optional
|
||||
|
||||
2. **Return Values**:
|
||||
- On success: it returns a tuple of `(bool, Any)`. For example: `(True, validated_result)`
|
||||
- On Failure: it returns a tuple of `(bool, str)`. For example: `(False, "Error message explain the failure")`
|
||||
|
||||
### LLMGuardrail
|
||||
|
||||
The `LLMGuardrail` class offers a robust mechanism for validating task outputs.
|
||||
|
||||
### Error Handling Best Practices
|
||||
|
||||
1. **Structured Error Responses**:
|
||||
```python Code
|
||||
from crewai import TaskOutput, LLMGuardrail
|
||||
|
||||
def validate_with_context(result: TaskOutput) -> Tuple[bool, Any]:
|
||||
try:
|
||||
# Main validation logic
|
||||
validated_data = perform_validation(result)
|
||||
return (True, validated_data)
|
||||
except ValidationError as e:
|
||||
return (False, f"VALIDATION_ERROR: {str(e)}")
|
||||
except Exception as e:
|
||||
return (False, str(e))
|
||||
```
|
||||
|
||||
2. **Error Categories**:
|
||||
- Use specific error codes
|
||||
- Include relevant context
|
||||
- Provide actionable feedback
|
||||
|
||||
3. **Validation Chain**:
|
||||
```python Code
|
||||
from typing import Any, Dict, List, Tuple, Union
|
||||
from crewai import TaskOutput
|
||||
|
||||
def complex_validation(result: TaskOutput) -> Tuple[bool, Any]:
|
||||
"""Chain multiple validation steps."""
|
||||
# Step 1: Basic validation
|
||||
if not result:
|
||||
return (False, "Empty result")
|
||||
|
||||
# Step 2: Content validation
|
||||
try:
|
||||
validated = validate_content(result)
|
||||
if not validated:
|
||||
return (False, "Invalid content")
|
||||
|
||||
# Step 3: Format validation
|
||||
formatted = format_output(validated)
|
||||
return (True, formatted)
|
||||
except Exception as e:
|
||||
return (False, str(e))
|
||||
```
|
||||
|
||||
### Handling Guardrail Results
|
||||
|
||||
When a guardrail returns `(False, error)`:
|
||||
1. The error is sent back to the agent
|
||||
2. The agent attempts to fix the issue
|
||||
3. The process repeats until:
|
||||
- The guardrail returns `(True, result)`
|
||||
- Maximum retries are reached
|
||||
|
||||
Example with retry handling:
|
||||
```python Code
|
||||
from typing import Optional, Tuple, Union
|
||||
from crewai import TaskOutput, Task
|
||||
|
||||
def validate_json_output(result: TaskOutput) -> Tuple[bool, Any]:
|
||||
"""Validate and parse JSON output."""
|
||||
try:
|
||||
# Try to parse as JSON
|
||||
data = json.loads(result)
|
||||
return (True, data)
|
||||
except json.JSONDecodeError as e:
|
||||
return (False, "Invalid JSON format")
|
||||
|
||||
task = Task(
|
||||
description="Generate a JSON report",
|
||||
expected_output="A valid JSON object",
|
||||
agent=analyst,
|
||||
guardrail=validate_json_output,
|
||||
max_retries=3 # Limit retry attempts
|
||||
)
|
||||
```
|
||||
|
||||
## Getting Structured Consistent Outputs from Tasks
|
||||
|
||||
<Note>
|
||||
It's also important to note that the output of the final task of a crew becomes the final output of the actual crew itself.
|
||||
</Note>
|
||||
|
||||
### Using `output_pydantic`
|
||||
The `output_pydantic` property allows you to define a Pydantic model that the task output should conform to. This ensures that the output is not only structured but also validated according to the Pydantic model.
|
||||
|
||||
Here's an example demonstrating how to use output_pydantic:
|
||||
|
||||
```python Code
|
||||
import json
|
||||
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from pydantic import BaseModel
|
||||
|
||||
|
||||
class Blog(BaseModel):
|
||||
title: str
|
||||
content: str
|
||||
|
||||
|
||||
blog_agent = Agent(
|
||||
role="Blog Content Generator Agent",
|
||||
goal="Generate a blog title and content",
|
||||
backstory="""You are an expert content creator, skilled in crafting engaging and informative blog posts.""",
|
||||
verbose=False,
|
||||
allow_delegation=False,
|
||||
llm="gpt-4o",
|
||||
)
|
||||
|
||||
task1 = Task(
|
||||
description="""Create a blog title and content on a given topic. Make sure the content is under 200 words.""",
|
||||
expected_output="A compelling blog title and well-written content.",
|
||||
agent=blog_agent,
|
||||
output_pydantic=Blog,
|
||||
)
|
||||
|
||||
# Instantiate your crew with a sequential process
|
||||
crew = Crew(
|
||||
agents=[blog_agent],
|
||||
tasks=[task1],
|
||||
verbose=True,
|
||||
process=Process.sequential,
|
||||
)
|
||||
|
||||
result = crew.kickoff()
|
||||
|
||||
# Option 1: Accessing Properties Using Dictionary-Style Indexing
|
||||
print("Accessing Properties - Option 1")
|
||||
title = result["title"]
|
||||
content = result["content"]
|
||||
print("Title:", title)
|
||||
print("Content:", content)
|
||||
|
||||
# Option 2: Accessing Properties Directly from the Pydantic Model
|
||||
print("Accessing Properties - Option 2")
|
||||
title = result.pydantic.title
|
||||
content = result.pydantic.content
|
||||
print("Title:", title)
|
||||
print("Content:", content)
|
||||
|
||||
# Option 3: Accessing Properties Using the to_dict() Method
|
||||
print("Accessing Properties - Option 3")
|
||||
output_dict = result.to_dict()
|
||||
title = output_dict["title"]
|
||||
content = output_dict["content"]
|
||||
print("Title:", title)
|
||||
print("Content:", content)
|
||||
|
||||
# Option 4: Printing the Entire Blog Object
|
||||
print("Accessing Properties - Option 5")
|
||||
print("Blog:", result)
|
||||
|
||||
```
|
||||
In this example:
|
||||
* A Pydantic model Blog is defined with title and content fields.
|
||||
* The task task1 uses the output_pydantic property to specify that its output should conform to the Blog model.
|
||||
* After executing the crew, you can access the structured output in multiple ways as shown.
|
||||
|
||||
#### Explanation of Accessing the Output
|
||||
1. Dictionary-Style Indexing: You can directly access the fields using result["field_name"]. This works because the CrewOutput class implements the __getitem__ method.
|
||||
2. Directly from Pydantic Model: Access the attributes directly from the result.pydantic object.
|
||||
3. Using to_dict() Method: Convert the output to a dictionary and access the fields.
|
||||
4. Printing the Entire Object: Simply print the result object to see the structured output.
|
||||
|
||||
### Using `output_json`
|
||||
The `output_json` property allows you to define the expected output in JSON format. This ensures that the task's output is a valid JSON structure that can be easily parsed and used in your application.
|
||||
|
||||
Here's an example demonstrating how to use `output_json`:
|
||||
|
||||
```python Code
|
||||
import json
|
||||
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from pydantic import BaseModel
|
||||
|
||||
|
||||
# Define the Pydantic model for the blog
|
||||
class Blog(BaseModel):
|
||||
title: str
|
||||
content: str
|
||||
|
||||
|
||||
# Define the agent
|
||||
blog_agent = Agent(
|
||||
role="Blog Content Generator Agent",
|
||||
goal="Generate a blog title and content",
|
||||
backstory="""You are an expert content creator, skilled in crafting engaging and informative blog posts.""",
|
||||
verbose=False,
|
||||
allow_delegation=False,
|
||||
llm="gpt-4o",
|
||||
)
|
||||
|
||||
# Define the task with output_json set to the Blog model
|
||||
task1 = Task(
|
||||
description="""Create a blog title and content on a given topic. Make sure the content is under 200 words.""",
|
||||
expected_output="A JSON object with 'title' and 'content' fields.",
|
||||
agent=blog_agent,
|
||||
output_json=Blog,
|
||||
)
|
||||
|
||||
# Instantiate the crew with a sequential process
|
||||
crew = Crew(
|
||||
agents=[blog_agent],
|
||||
tasks=[task1],
|
||||
verbose=True,
|
||||
process=Process.sequential,
|
||||
)
|
||||
|
||||
# Kickoff the crew to execute the task
|
||||
result = crew.kickoff()
|
||||
|
||||
# Option 1: Accessing Properties Using Dictionary-Style Indexing
|
||||
print("Accessing Properties - Option 1")
|
||||
title = result["title"]
|
||||
content = result["content"]
|
||||
print("Title:", title)
|
||||
print("Content:", content)
|
||||
|
||||
# Option 2: Printing the Entire Blog Object
|
||||
print("Accessing Properties - Option 2")
|
||||
print("Blog:", result)
|
||||
```
|
||||
|
||||
In this example:
|
||||
* A Pydantic model Blog is defined with title and content fields, which is used to specify the structure of the JSON output.
|
||||
* The task task1 uses the output_json property to indicate that it expects a JSON output conforming to the Blog model.
|
||||
* After executing the crew, you can access the structured JSON output in two ways as shown.
|
||||
|
||||
#### Explanation of Accessing the Output
|
||||
|
||||
1. Accessing Properties Using Dictionary-Style Indexing: You can access the fields directly using result["field_name"]. This is possible because the CrewOutput class implements the __getitem__ method, allowing you to treat the output like a dictionary. In this option, we're retrieving the title and content from the result.
|
||||
2. Printing the Entire Blog Object: By printing result, you get the string representation of the CrewOutput object. Since the __str__ method is implemented to return the JSON output, this will display the entire output as a formatted string representing the Blog object.
|
||||
|
||||
---
|
||||
|
||||
By using output_pydantic or output_json, you ensure that your tasks produce outputs in a consistent and structured format, making it easier to process and utilize the data within your application or across multiple tasks.

These validations help in maintaining the consistency and reliability of task executions within the crewAI framework.
|
||||
|
||||
## Task Guardrails
|
||||
|
||||
Task guardrails provide a powerful way to validate, transform, or filter task outputs before they are passed to the next task. Guardrails are optional functions that execute before the next task starts, allowing you to ensure that task outputs meet specific requirements or formats.
|
||||
|
||||
### Basic Usage
|
||||
|
||||
#### Define your own logic to validate
|
||||
|
||||
```python Code
|
||||
from typing import Tuple, Union
|
||||
from crewai import Task
|
||||
|
||||
def validate_json_output(result: str) -> Tuple[bool, Union[dict, str]]:
|
||||
"""Validate that the output is valid JSON."""
|
||||
try:
|
||||
json_data = json.loads(result)
|
||||
return (True, json_data)
|
||||
except json.JSONDecodeError:
|
||||
return (False, "Output must be valid JSON")
|
||||
|
||||
task = Task(
|
||||
description="Generate JSON data",
|
||||
expected_output="Valid JSON object",
|
||||
guardrail=validate_json_output
|
||||
)
|
||||
```
|
||||
|
||||
#### Leverage a no-code approach for validation
|
||||
|
||||
```python Code
|
||||
from crewai import Task
|
||||
|
||||
task = Task(
|
||||
description="Generate JSON data",
|
||||
expected_output="Valid JSON object",
|
||||
guardrail="Ensure the response is a valid JSON object"
|
||||
)
|
||||
```
|
||||
|
||||
#### Using YAML
|
||||
|
||||
```yaml
|
||||
research_task:
|
||||
...
|
||||
guardrail: make sure each bullet contains a minimum of 100 words
|
||||
...
|
||||
```
|
||||
|
||||
```python Code
|
||||
@CrewBase
|
||||
class InternalCrew:
|
||||
agents_config = "config/agents.yaml"
|
||||
tasks_config = "config/tasks.yaml"
|
||||
|
||||
...
|
||||
@task
|
||||
def research_task(self):
|
||||
return Task(config=self.tasks_config["research_task"]) # type: ignore[index]
|
||||
...
|
||||
```
|
||||
|
||||
|
||||
#### Use custom models for code generation
|
||||
|
||||
```python Code
|
||||
from crewai import Task
|
||||
from crewai.llm import LLM
|
||||
|
||||
task = Task(
|
||||
description="Generate JSON data",
|
||||
expected_output="Valid JSON object",
|
||||
guardrail=LLMGuardrail(
|
||||
description="Ensure the response is a valid JSON object",
|
||||
llm=LLM(model="gpt-4o-mini"),
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
### How Guardrails Work
|
||||
|
||||
1. **Optional Attribute**: Guardrails are an optional attribute at the task level, allowing you to add validation only where needed.
|
||||
2. **Execution Timing**: The guardrail function is executed before the next task starts, ensuring valid data flow between tasks.
|
||||
3. **Return Format**: Guardrails must return a tuple of `(success, data)`:
|
||||
- If `success` is `True`, `data` is the validated/transformed result
|
||||
- If `success` is `False`, `data` is the error message
|
||||
4. **Result Routing**:
|
||||
- On success (`True`), the result is automatically passed to the next task
|
||||
- On failure (`False`), the error is sent back to the agent to generate a new answer
|
||||
|
||||
### Common Use Cases
|
||||
|
||||
#### Data Format Validation
|
||||
```python Code
|
||||
def validate_email_format(result: str) -> Tuple[bool, Union[str, str]]:
|
||||
"""Ensure the output contains a valid email address."""
|
||||
import re
|
||||
email_pattern = r'^[\w\.-]+@[\w\.-]+\.\w+$'
|
||||
if re.match(email_pattern, result.strip()):
|
||||
return (True, result.strip())
|
||||
return (False, "Output must be a valid email address")
|
||||
```
|
||||
|
||||
#### Content Filtering
|
||||
```python Code
|
||||
def filter_sensitive_info(result: str) -> Tuple[bool, Union[str, str]]:
|
||||
"""Remove or validate sensitive information."""
|
||||
sensitive_patterns = ['SSN:', 'password:', 'secret:']
|
||||
for pattern in sensitive_patterns:
|
||||
if pattern.lower() in result.lower():
|
||||
return (False, f"Output contains sensitive information ({pattern})")
|
||||
return (True, result)
|
||||
```
|
||||
|
||||
#### Data Transformation
|
||||
```python Code
|
||||
def normalize_phone_number(result: str) -> Tuple[bool, Union[str, str]]:
|
||||
"""Ensure phone numbers are in a consistent format."""
|
||||
import re
|
||||
digits = re.sub(r'\D', '', result)
|
||||
if len(digits) == 10:
|
||||
formatted = f"({digits[:3]}) {digits[3:6]}-{digits[6:]}"
|
||||
return (True, formatted)
|
||||
return (False, "Output must be a 10-digit phone number")
|
||||
```
|
||||
|
||||
### Advanced Features
|
||||
|
||||
#### Chaining Multiple Validations
|
||||
```python Code
|
||||
def chain_validations(*validators):
|
||||
"""Chain multiple validators together."""
|
||||
def combined_validator(result):
|
||||
for validator in validators:
|
||||
success, data = validator(result)
|
||||
if not success:
|
||||
return (False, data)
|
||||
result = data
|
||||
return (True, result)
|
||||
return combined_validator
|
||||
|
||||

|
||||
validate_email_format,
|
||||
filter_sensitive_info
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
#### Custom Retry Logic
|
||||
```python Code

||||
```bash
|
||||
pip install 'crewai[tools]'

There are two main ways for one to create a CrewAI tool:
|
||||
|
||||
### Subclassing `BaseTool`
|
||||
|
||||
```python Code
|
||||
from crewai_tools import BaseTool
|
||||
from crewai.tools import BaseTool
|
||||
from pydantic import BaseModel, Field
|
||||
|
||||
class MyToolInput(BaseModel):
|
||||
"""Input schema for MyCustomTool."""
|
||||
argument: str = Field(..., description="Description of the argument.")
|
||||
|
||||
class MyCustomTool(BaseTool):
|
||||
name: str = "Name of my tool"
|
||||
description: str = "Clear description for what this tool is useful for, your agent will need this information to use it."
|
||||
description: str = "What this tool does. It's vital for effective utilization."
|
||||
args_schema: Type[BaseModel] = MyToolInput
|
||||
|
||||
def _run(self, argument: str) -> str:
|
||||
# Implementation goes here
|
||||
return "Result from custom tool"
|
||||
# Your tool's logic here
|
||||
return "Tool's result"
|
||||
```
|
||||
|
||||
## Asynchronous Tool Support
|
||||
|
||||
CrewAI supports asynchronous tools, allowing you to implement tools that perform non-blocking operations like network requests, file I/O, or other async operations without blocking the main execution thread.
|
||||
|
||||
### Creating Async Tools
|
||||
|
||||
You can create async tools in two ways:
|
||||
|
||||
#### 1. Using the `tool` Decorator with Async Functions
|
||||
|
||||
```python Code
|
||||
from crewai.tools import tool
|
||||
|
||||
@tool("fetch_data_async")
|
||||
async def fetch_data_async(query: str) -> str:
|
||||
"""Asynchronously fetch data based on the query."""
|
||||
# Simulate async operation
|
||||
await asyncio.sleep(1)
|
||||
return f"Data retrieved for {query}"
|
||||
```
|
||||
|
||||
#### 2. Implementing Async Methods in Custom Tool Classes
|
||||
|
||||
```python Code
|
||||
from crewai.tools import BaseTool
|
||||
|
||||
class AsyncCustomTool(BaseTool):
|
||||
name: str = "async_custom_tool"
|
||||
description: str = "An asynchronous custom tool"
|
||||
|
||||
async def _run(self, query: str = "") -> str:
|
||||
"""Asynchronously run the tool"""
|
||||
# Your async implementation here
|
||||
await asyncio.sleep(1)
|
||||
return f"Processed {query} asynchronously"
|
||||
```
|
||||
|
||||
### Using Async Tools
|
||||
|
||||
Async tools work seamlessly in both standard Crew workflows and Flow-based workflows:
|
||||
|
||||
```python Code
|
||||
# In standard Crew
|
||||
agent = Agent(role="researcher", tools=[async_custom_tool])
|
||||
|
||||
# In Flow
|
||||
class MyFlow(Flow):
|
||||
@start()
|
||||
async def begin(self):
|
||||
crew = Crew(agents=[agent])
|
||||
result = await crew.kickoff_async()
|
||||
return result
|
||||
```
|
||||
|
||||
The CrewAI framework automatically handles the execution of both synchronous and asynchronous tools, so you don't need to worry about how to call them differently.
|
||||
|
||||
### Utilizing the `tool` Decorator
|
||||
|
||||
```python Code
|
||||
from crewai_tools import tool
|
||||
from crewai.tools import tool
|
||||
@tool("Name of my tool")
|
||||
def my_tool(question: str) -> str:

### Custom Caching Mechanism
|
||||
|
||||
<Tip>
|
||||
Tools can optionally implement a `cache_function` to fine-tune caching behavior. This function determines when to cache results based on specific conditions, offering granular control over caching logic.

|
||||
description: |
|
||||
REST API for interacting with your deployed CrewAI crews on CrewAI Enterprise.
|
||||
|
||||
## Getting Started
|
||||
|
||||
1. **Find your crew URL**: Get your unique crew URL from the CrewAI Enterprise dashboard
|
||||
2. **Copy examples**: Use the code examples from each endpoint page as templates
|
||||
3. **Replace placeholders**: Update URLs and tokens with your actual values
|
||||
4. **Test with your tools**: Use cURL, Postman, or your preferred API client
|
||||
|
||||
## Authentication
|
||||
|
||||
All API requests require a bearer token for authentication. There are two types of tokens:
|
||||
|
||||
- **Bearer Token**: Organization-level token for full crew operations
|
||||
- **User Bearer Token**: User-scoped token for individual access with limited permissions
|
||||
|
||||
You can find your bearer tokens in the Status tab of your crew's detail page in the CrewAI Enterprise dashboard.
|
||||
|
||||
## Reference Documentation
|
||||
|
||||
This documentation provides comprehensive examples for each endpoint:
|
||||
|
||||
- **Request formats** with all required and optional parameters
|
||||
- **Response examples** for success and error scenarios
|
||||
- **Code samples** in multiple programming languages
|
||||
- **Authentication patterns** with proper Bearer token usage
|
||||
|
||||
Copy the examples and customize them with your actual crew URL and authentication tokens.
|
||||
|
||||
## Workflow
|
||||
|
||||
1. **Discover inputs** using `GET /inputs`
|
||||
2. **Start execution** using `POST /kickoff`
|
||||
3. **Monitor progress** using `GET /status/{kickoff_id}`

|
||||
|
||||
## Overview
|
||||
|
||||
The Hallucination Guardrail is an enterprise feature that validates AI-generated content to ensure it's grounded in facts and doesn't contain hallucinations. It analyzes task outputs against reference context and provides detailed feedback when potentially hallucinated content is detected.
|
||||
|
||||
## What are Hallucinations?
|
||||
|
||||
AI hallucinations occur when language models generate content that appears plausible but is factually incorrect or not supported by the provided context. The Hallucination Guardrail helps prevent these issues by:
|
||||
|
||||
- Comparing outputs against reference context
|
||||
- Evaluating faithfulness to source material
|
||||
- Providing detailed feedback on problematic content
|
||||
- Supporting custom thresholds for validation strictness
|
||||
|
||||
## Basic Usage
|
||||
|
||||
### Setting Up the Guardrail
|
||||
|
||||
```python
|
||||
from crewai.tasks.hallucination_guardrail import HallucinationGuardrail
|
||||
from crewai import LLM
|
||||
|
||||
# Basic usage - will use task's expected_output as context
|
||||
guardrail = HallucinationGuardrail(
|
||||
llm=LLM(model="gpt-4o-mini")
|
||||
)
|
||||
|
||||
# With explicit reference context
|
||||
context_guardrail = HallucinationGuardrail(
|
||||
context="AI helps with various tasks including analysis and generation.",
|
||||
llm=LLM(model="gpt-4o-mini")
|
||||
)
|
||||
```
|
||||
|
||||
### Adding to Tasks
|
||||
|
||||
```python
|
||||
from crewai import Task
|
||||
|
||||
# Create your task with the guardrail
|
||||
task = Task(
|
||||
description="Write a summary about AI capabilities",
|
||||
expected_output="A factual summary based on the provided context",
|
||||
agent=my_agent,
|
||||
guardrail=guardrail # Add the guardrail to validate output
|
||||
)
|
||||
```
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Custom Threshold Validation
|
||||
|
||||
For stricter validation, you can set a custom faithfulness threshold (0-10 scale):
|
||||
|
||||
```python
|
||||
# Strict guardrail requiring high faithfulness score
|
||||
strict_guardrail = HallucinationGuardrail(
|
||||
context="Quantum computing uses qubits that exist in superposition states.",
|
||||
llm=LLM(model="gpt-4o-mini"),
|
||||
threshold=8.0 # Requires score >= 8 to pass validation
|
||||
)
|
||||
```
|
||||
|
||||
### Including Tool Response Context
|
||||
|
||||
When your task uses tools, you can include tool responses for more accurate validation:
|
||||
|
||||
```python
|
||||
# Guardrail with tool response context
|
||||
weather_guardrail = HallucinationGuardrail(
|
||||
context="Current weather information for the requested location",
|
||||
llm=LLM(model="gpt-4o-mini"),
|
||||
tool_response="Weather API returned: Temperature 22°C, Humidity 65%, Clear skies"
|
||||
)
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
### Validation Process
|
||||
|
||||
1. **Context Analysis**: The guardrail compares task output against the provided reference context
|
||||
2. **Faithfulness Scoring**: Uses an internal evaluator to assign a faithfulness score (0-10)
|
||||
3. **Verdict Determination**: Determines if content is faithful or contains hallucinations
|
||||
4. **Threshold Checking**: If a custom threshold is set, validates against that score
|
||||
5. **Feedback Generation**: Provides detailed reasons when validation fails
|
||||
|
||||
### Validation Logic
|
||||
|
||||
- **Default Mode**: Uses verdict-based validation (FAITHFUL vs HALLUCINATED)
|
||||
- **Threshold Mode**: Requires faithfulness score to meet or exceed the specified threshold
|
||||
- **Error Handling**: Gracefully handles evaluation errors and provides informative feedback
|
||||
|
||||
## Guardrail Results
|
||||
|
||||
The guardrail returns structured results indicating validation status:
|
||||
|
||||
```python
|
||||
# Example of guardrail result structure
|
||||
{
|
||||
"valid": False,
|
||||
"feedback": "Content appears to be hallucinated (score: 4.2/10, verdict: HALLUCINATED). The output contains information not supported by the provided context."
|
||||
}
|
||||
```
|
||||
|
||||
### Result Properties
|
||||
|
||||
- **valid**: Boolean indicating whether the output passed validation
|
||||
- **feedback**: Detailed explanation when validation fails, including:
|
||||
- Faithfulness score
|
||||
- Verdict classification
|
||||
- Specific reasons for failure
|
||||
|
||||
## Integration with Task System
|
||||
|
||||
### Automatic Validation
|
||||
|
||||
When a guardrail is added to a task, it automatically validates the output before the task is marked as complete:
|
||||
|
||||
```python
|
||||
# Task output validation flow
|
||||
task_output = agent.execute_task(task)
|
||||
validation_result = guardrail(task_output)
|
||||
|
||||
if validation_result.valid:
|
||||
# Task completes successfully
|
||||
return task_output
|
||||
else:
|
||||
# Task fails with validation feedback
|
||||
raise ValidationError(validation_result.feedback)
|
||||
```
|
||||
|
||||
### Event Tracking
|
||||
|
||||
The guardrail integrates with CrewAI's event system to provide observability:
|
||||
|
||||
- **Validation Started**: When guardrail evaluation begins
|
||||
- **Validation Completed**: When evaluation finishes with results
|
||||
- **Validation Failed**: When technical errors occur during evaluation
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Context Guidelines
|
||||
|
||||
<Steps>
|
||||
<Step title="Provide Comprehensive Context">
|
||||
Include all relevant factual information that the AI should base its output on:
|
||||
|
||||
```python
|
||||
context = """
|
||||
Company XYZ was founded in 2020 and specializes in renewable energy solutions.
|
||||
They have 150 employees and generated $50M revenue in 2023.
|
||||
Their main products include solar panels and wind turbines.
|
||||
"""
|
||||
```
|
||||
</Step>
|
||||
|
||||
<Step title="Keep Context Relevant">
|
||||
Only include information directly related to the task to avoid confusion:
|
||||
|
||||
```python
|
||||
# Good: Focused context
|
||||
context = "The current weather in New York is 18°C with light rain."
|
||||
|
||||
# Avoid: Unrelated information
|
||||
context = "The weather is 18°C. The city has 8 million people. Traffic is heavy."
|
||||
```
|
||||
</Step>
|
||||
|
||||
<Step title="Update Context Regularly">
|
||||
Ensure your reference context reflects current, accurate information.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
### Threshold Selection
|
||||
|
||||
<Steps>
|
||||
<Step title="Start with Default Validation">
|
||||
Begin without custom thresholds to understand baseline performance.
|
||||
</Step>
|
||||
|
||||
<Step title="Adjust Based on Requirements">
|
||||
- **High-stakes content**: Use threshold 8-10 for maximum accuracy
|
||||
- **General content**: Use threshold 6-7 for balanced validation
|
||||
- **Creative content**: Use threshold 4-5 or default verdict-based validation
|
||||
</Step>
|
||||
|
||||
<Step title="Monitor and Iterate">
|
||||
Track validation results and adjust thresholds based on false positives/negatives.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Impact on Execution Time
|
||||
|
||||
- **Validation Overhead**: Each guardrail adds ~1-3 seconds per task
|
||||
- **LLM Efficiency**: Choose efficient models for evaluation (e.g., gpt-4o-mini)
|
||||
|
||||
### Cost Optimization
|
||||
|
||||
- **Model Selection**: Use smaller, efficient models for guardrail evaluation
|
||||
- **Context Size**: Keep reference context concise but comprehensive
|
||||
- **Caching**: Consider caching validation results for repeated content
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
<Accordion title="Validation Always Fails">
|
||||
**Possible Causes:**
|
||||
- Context is too restrictive or unrelated to task output
|
||||
- Threshold is set too high for the content type
|
||||
- Reference context contains outdated information
|
||||
|
||||
**Solutions:**
|
||||
- Review and update context to match task requirements
|
||||
- Lower threshold or use default verdict-based validation
|
||||
- Ensure context is current and accurate
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="False Positives (Valid Content Marked Invalid)">
|
||||
**Possible Causes:**
|
||||
- Threshold too high for creative or interpretive tasks
|
||||
- Context doesn't cover all valid aspects of the output
|
||||
- Evaluation model being overly conservative
|
||||
|
||||
**Solutions:**
|
||||
- Lower threshold or use default validation
|
||||
- Expand context to include broader acceptable content
|
||||
- Test with different evaluation models
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="Evaluation Errors">
|
||||
**Possible Causes:**
|
||||
- Network connectivity issues
|
||||
- LLM model unavailable or rate limited
|
||||
- Malformed task output or context
|
||||
|
||||
**Solutions:**
|
||||
- Check network connectivity and LLM service status
|
||||
- Implement retry logic for transient failures
|
||||
- Validate task output format before guardrail evaluation

|
||||
```
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Usage
|
||||
<Tip>
|
||||
All the services you are authenticated into will be available as tools. So all you need to do is add the `CrewaiEnterpriseTools` to your agent and you are good to go.
|
||||
</Tip>
|
||||
|
||||
```python
|
||||
from crewai import Agent, Task, Crew
|
||||
from crewai_tools import CrewaiEnterpriseTools
|
||||
|
||||
# Get enterprise tools (Gmail tool will be included)
|
||||
enterprise_tools = CrewaiEnterpriseTools(
|
||||
enterprise_token="your_enterprise_token"
|
||||
)
|
||||
# print the tools
|
||||
print(enterprise_tools)
|
||||
|
||||
# Create an agent with Gmail capabilities
|
||||
email_agent = Agent(
|
||||
role="Email Manager",
|
||||
goal="Manage and organize email communications",
|
||||
backstory="An AI assistant specialized in email management and communication.",
|
||||
tools=[enterprise_tools]
|
||||
)
|
||||
|
||||
# Task to send an email
|
||||
email_task = Task(
|
||||
description="Draft and send a follow-up email to john@example.com about the project update",
|
||||
agent=email_agent,
|
||||
expected_output="Confirmation that email was sent successfully"
|
||||
)
|
||||
|
||||
# Run the task
|
||||
crew = Crew(
|
||||
agents=[email_agent],
|
||||
tasks=[email_task]
|
||||
)
|
||||
|
||||
# Run the crew
|
||||
crew.kickoff()
|
||||
```
|
||||
|
||||
### Filtering Tools
|
||||
|
||||
```python
|
||||
from crewai_tools import CrewaiEnterpriseTools
|
||||
|
||||
enterprise_tools = CrewaiEnterpriseTools(
|
||||
actions_list=["gmail_find_email"] # only gmail_find_email tool will be available
|
||||
)
|
||||
gmail_tool = enterprise_tools[0]
|
||||
|
||||
gmail_agent = Agent(
|
||||
role="Gmail Manager",
|
||||
goal="Manage gmail communications and notifications",
|
||||
backstory="An AI assistant that helps coordinate gmail communications.",
|
||||
tools=[gmail_tool]
|
||||
)
|
||||
|
||||
notification_task = Task(
|
||||
description="Find the email from john@example.com",
|
||||
agent=gmail_agent,
|
||||
expected_output="Email found from john@example.com"
|
||||
)
|
||||
|
||||
# Run the task
|
||||
crew = Crew(
|
||||
agents=[slack_agent],
|
||||
tasks=[notification_task]
|
||||
)
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Security
|
||||
- **Principle of Least Privilege**: Only grant the minimum permissions required for your agents' tasks
|
||||
- **Regular Audits**: Periodically review connected integrations and their permissions
|
||||
- **Secure Credentials**: Never hardcode credentials; use CrewAI's secure authentication flow
|
||||
|
||||
|
||||
### Filtering Tools
|
||||
On a deployed crew, you can specify which actions are avialbel for each integration from the settings page of the service you connected to.
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
|
||||
### Scoped Deployments for multi user organizations
|
||||
You can deploy your crew and scope each integration to a specific user. For example, a crew that connects to google can use a specific user's gmail account.
|
||||
|
||||
<Tip>
|
||||
This is useful for multi user organizations where you want to scope the integration to a specific user.
|
||||
</Tip>
|
||||
|
||||
|
||||
Use the `user_bearer_token` to scope the integration to a specific user so that when the crew is kicked off, it will use the user's bearer token to authenticate with the integration. If user is not logged in, then the crew will not use any connected integrations. Use the default bearer token to authenticate with the integrations thats deployed with the crew.

Tools can be:
|
||||
|
||||
- **Private**: accessible only within your organization (default)
|
||||
- **Public**: accessible to all CrewAI users if published with the `--public` flag
|
||||
|
||||
The repository is not a version control system. Use Git to track code changes and enable collaboration.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before using the Tool Repository, ensure you have:
|
||||
|
||||
- A [CrewAI Enterprise](https://app.crewai.com) account
|
||||
- [CrewAI CLI](https://docs.crewai.com/concepts/cli#cli) installed
|
||||
- uv>=0.5.0 installed. Check out [how to upgrade](https://docs.astral.sh/uv/getting-started/installation/#upgrading-uv)
|
||||
- [Git](https://git-scm.com) installed and configured
|
||||
- Access permissions to publish or install tools in your CrewAI Enterprise organization
|
||||
|
||||
## Installing Tools
|
||||
|
||||
To install a tool:
|
||||
|
||||
```bash
|
||||
crewai tool install <tool-name>
|
||||
```
|
||||
|
||||
This installs the tool and adds it to `pyproject.toml`.
|
||||
|
||||
## Creating and Publishing Tools
|
||||
|
||||
To create a new tool project:
|
||||
|
||||
```bash
|
||||
crewai tool create <tool-name>
|
||||
```
|
||||
|
||||
This generates a scaffolded tool project locally.
|
||||
|
||||
After making changes, initialize a Git repository and commit the code:
|
||||
|
||||
```bash
|
||||
git init
|
||||
git add .
|
||||
git commit -m "Initial version"
|
||||
```
|
||||
|
||||
To publish the tool:
|
||||
|
||||
```bash
|
||||
crewai tool publish
|
||||
```
|
||||
|
||||
By default, tools are published as private. To make a tool public:
|
||||
|
||||
```bash
|
||||
crewai tool publish --public
|
||||
```
|
||||
|
||||
For more details on how to build tools, see [Creating your own tools](https://docs.crewai.com/concepts/tools#creating-your-own-tools).
|
||||
|
||||
## Updating Tools
|
||||
|
||||
To update a published tool:
|
||||
|
||||
1. Modify the tool locally
|
||||
2. Update the version in `pyproject.toml` (e.g., from `0.1.0` to `0.1.1`)
|
||||
3. Commit the changes and publish
|
||||
|
||||
```bash
|
||||
git commit -m "Update version to 0.1.1"
|
||||
crewai tool publish
|
||||
```
|
||||
|
||||
## Deleting Tools
|
||||
|
||||
To delete a tool:
|
||||
|
||||
1. Go to [CrewAI Enterprise](https://app.crewai.com)
|
||||
2. Navigate to **Tools**
|
||||
3. Select the tool
|
||||
4. Click **Delete**
|
||||
|
||||
<Warning>
|
||||
Deletion is permanent. Deleted tools cannot be restored or re-installed.
|
||||
</Warning>
|
||||
|
||||
## Security Checks
|
||||
|
||||
Every published version undergoes automated security checks, and are only available to install after they pass.
|
||||
|
||||
You can check the security check status of a tool at:

|
||||
|
||||
## Overview
|
||||
|
||||
Traces provide comprehensive visibility into your crew executions, helping you monitor performance, debug issues, and optimize your AI agent workflows.
|
||||
|
||||
## What are Traces?
|
||||
|
||||
Traces in CrewAI Enterprise are detailed execution records that capture every aspect of your crew's operation, from initial inputs to final outputs. They record:
|
||||
|
||||
- Agent thoughts and reasoning
|
||||
- Task execution details
|
||||
- Tool usage and outputs
|
||||
- Token consumption metrics
|
||||
- Execution times
|
||||
- Cost estimates
|
||||
|
||||

## Understanding the Trace Interface
|
||||
|
||||
The trace interface is divided into several sections, each providing different insights into your crew's execution:
|
||||
|
||||
### 1. Execution Summary
|
||||
|
||||
The top section displays high-level metrics about the execution:
|
||||
|
||||
- **Total Tokens**: Number of tokens consumed across all tasks
|
||||
- **Prompt Tokens**: Tokens used in prompts to the LLM
|
||||
- **Completion Tokens**: Tokens generated in LLM responses
|
||||
- **Requests**: Number of API calls made
|
||||
- **Execution Time**: Total duration of the crew run
|
||||
- **Estimated Cost**: Approximate cost based on token usage
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
### 2. Tasks & Agents
|
||||
|
||||
This section shows all tasks and agents that were part of the crew execution:
|
||||
|
||||
- Task name and agent assignment
|
||||
- Agents and LLMs used for each task
|
||||
- Status (completed/failed)
|
||||
- Individual execution time of the task
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
### 3. Final Output
|
||||
|
||||

|
||||

|
||||
</Frame>
|
||||
|
||||
### 5. Detailed Task View
|
||||
|
||||
When you click on a specific task in the timeline or task list, you'll see:
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
- **Task Key**: Unique identifier for the task

|
||||
- **Agent**: Which agent performed the task
|
||||
- **LLM**: Language model used for this task
|
||||
- **Start/End Time**: When the task began and completed
|
||||
- **Execution Time**: Duration of this specific task
|
||||
- **Task Description**: What the agent was instructed to do
|
||||
- **Expected Output**: What output format was requested
|
||||
- **Input**: Any input provided to this task from previous tasks
|
||||
- **Output**: The actual result produced by the agent
|
||||
|
||||
|
||||
## Using Traces for Debugging
|
||||
|
||||
Traces are invaluable for troubleshooting issues with your crews:
|
||||
|
||||
<Steps>
|
||||
<Step title="Identify Failure Points">
|
||||
When a crew execution doesn't produce the expected results, examine the trace to find where things went wrong. Look for:
|
||||
|
||||
- Failed tasks
|
||||
- Unexpected agent decisions
|
||||
- Tool usage errors
|
||||
- Misinterpreted instructions
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
</Step>
|
||||
|
||||
<Step title="Optimize Performance">
|
||||
Use execution metrics to identify performance bottlenecks:
|
||||
|
||||
- Tasks that took longer than expected
|
||||
- Excessive token usage
|
||||
- Redundant tool operations
|
||||
- Unnecessary API calls
|
||||
</Step>
|
||||
|
||||
<Step title="Improve Cost Efficiency">
|
||||
Analyze token usage and cost estimates to optimize your crew's efficiency:
|
||||
|
||||
- Consider using smaller models for simpler tasks
|
||||
- Refine prompts to be more concise
|
||||
- Cache frequently accessed information
|
||||
- Structure tasks to minimize redundant operations
|
||||

title: Webhook Streaming
|
||||
description: "Using Webhook Streaming to stream events to your webhook"
|
||||
icon: "webhook"
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Enterprise Event Streaming lets you receive real-time webhook updates about your crews and flows deployed to
|
||||
CrewAI Enterprise, such as model calls, tool usage, and flow steps.
|
||||
|
||||
## Usage
|
||||
|
||||
When using the Kickoff API, include a `webhooks` object to your request, for example:
|
||||
|
||||
```json
|
||||
{
|
||||
"inputs": {"foo": "bar"},
|
||||
"webhooks": {
|
||||
"events": ["crew_kickoff_started", "llm_call_started"],
|
||||
"url": "https://your.endpoint/webhook",
|
||||
"realtime": false,
|
||||
"authentication": {
|
||||
"strategy": "bearer",
|
||||
"token": "my-secret-token"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
If `realtime` is set to `true`, each event is delivered individually and immediately, at the cost of crew/flow performance.
|
||||
|
||||
## Webhook Format
|
||||
|
||||
Each webhook sends a list of events:
|
||||
|
||||
```json
|
||||
{
|
||||
"events": [
|
||||
{
|
||||
"id": "event-id",
|
||||
"execution_id": "crew-run-id",
|
||||
"timestamp": "2025-02-16T10:58:44.965Z",
|
||||
"type": "llm_call_started",
|
||||
"data": {
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{"role": "system", "content": "You are an assistant."},
|
||||
{"role": "user", "content": "Summarize this article."}
|
||||
]
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The `data` object structure varies by event type. Refer to the [event list](https://github.com/crewAIInc/crewAI/tree/main/src/crewai/utilities/events) on GitHub.
|
||||
|
||||
As requests are sent over HTTP, the order of events can't be guaranteed. If you need ordering, use the `timestamp` field.
|
||||
|
||||
## Supported Events
|
||||
|
||||
CrewAI supports both system events and custom events in Enterprise Event Streaming. These events are sent to your configured webhook endpoint during crew and flow execution.
|
||||
|
||||
- `crew_kickoff_started`
|
||||
- `crew_step_started`
|
||||
- `crew_step_completed`
|
||||
- `crew_execution_completed`
|
||||
- `llm_call_started`
|
||||
- `llm_call_completed`
|
||||
- `tool_usage_started`
|
||||
- `tool_usage_completed`
|
||||
- `crew_test_failed`
|
||||
- *...and others*
|
||||
|
||||
Event names match the internal event bus. See [GitHub source](https://github.com/crewAIInc/crewAI/tree/main/src/crewai/utilities/events) for the full list.
|
||||
|
||||
You can emit your own custom events, and they will be delivered through the webhook stream alongside system events.

This guide walks you through connecting Azure OpenAI with Crew Studio for seamless enterprise AI operations.
|
||||
|
||||
## Setup Process
|
||||
|
||||
<Steps>
|
||||
<Step title="Access Azure OpenAI Studio">
|
||||
1. In Azure, go to `Azure AI Services > select your deployment > open Azure OpenAI Studio`.
|
||||
2. On the left menu, click `Deployments`. If you don't have one, create a deployment with your desired model.
|
||||
3. Once created, select your deployment and locate the `Target URI` and `Key` on the right side of the page. Keep this page open, as you'll need this information.
|
||||
<Frame>
|
||||
<img src="/images/enterprise/azure-openai-studio.png" alt="Azure OpenAI Studio" />
|
||||
</Frame>
|
||||
</Step>
|
||||
|
||||
<Step title="Configure CrewAI Enterprise Connection">
|
||||
4. In another tab, open `CrewAI Enterprise > LLM Connections`. Name your LLM Connection, select Azure as the provider, and choose the same model you selected in Azure.
|
||||
5. On the same page, add environment variables from step 3:
|
||||
- One named `AZURE_DEPLOYMENT_TARGET_URL` (using the Target URI). The URL should look like this: https://your-deployment.openai.azure.com/openai/deployments/gpt-4o/chat/completions?api-version=2024-08-01-preview
|
||||
- Another named `AZURE_API_KEY` (using the Key).
|
||||
6. Click `Add Connection` to save your LLM Connection.
|
||||
</Step>
|
||||
|
||||
<Step title="Set Default Configuration">
|
||||
7. In `CrewAI Enterprise > Settings > Defaults > Crew Studio LLM Settings`, set the new LLM Connection and model as defaults.
|
||||
</Step>
|
||||
|
||||
<Step title="Configure Network Access">
|
||||
8. Ensure network access settings:
|
||||
- In Azure, go to `Azure OpenAI > select your deployment`.
|
||||
- Navigate to `Resource Management > Networking`.
|
||||
- Ensure that `Allow access from all networks` is enabled. If this setting is restricted, CrewAI may be blocked from accessing your Azure OpenAI endpoint.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Verification
|
||||
|
||||
You're all set! Crew Studio will now use your Azure OpenAI connection. Test the connection by creating a simple crew or task to ensure everything is working properly.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If you encounter issues:
|
||||
- Verify the Target URI format matches the expected pattern
|
||||
- Check that the API key is correct and has proper permissions
|
||||
- Ensure network access is configured to allow CrewAI connections
|
||||
- Confirm the deployment model matches what you've configured in CrewAI

## Option 1: Deploy Using CrewAI CLI
|
||||
|
||||
The CLI provides the fastest way to deploy locally developed crews to the Enterprise platform.
|
||||
|
||||
<Steps>
|
||||
<Step title="Install CrewAI CLI">
|
||||
If you haven't already, install the CrewAI CLI:
|
||||
|
||||
```bash
|
||||
pip install crewai[tools]
|
||||
```
|
||||
|
||||
<Tip>
|
||||
The CLI comes with the main CrewAI package, but the `[tools]` extra ensures you have all deployment dependencies.
|
||||
</Tip>
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Authenticate with the Enterprise Platform">
|
||||
First, you need to authenticate your CLI with the CrewAI Enterprise platform:
|
||||
|
||||
```bash
|
||||
# If you already have a CrewAI Enterprise account
|
||||
crewai login
|
||||
|
||||
# If you're creating a new account
|
||||
crewai signup
|
||||
```
|
||||
|
||||
When you run either command, the CLI will:
|
||||
1. Display a URL and a unique device code
|
||||
2. Open your browser to the authentication page
|
||||
3. Prompt you to confirm the device
|
||||
4. Complete the authentication process
|
||||
|
||||
Upon successful authentication, you'll see a confirmation message in your terminal!
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Create a Deployment">
|
||||
|
||||
From your project directory, run:
|
||||
|
||||
```bash
|
||||
crewai deploy create
|
||||
```
|
||||
|
||||
This command will:
|
||||
1. Detect your GitHub repository information
|
||||
2. Identify environment variables in your local `.env` file
|
||||
3. Securely transfer these variables to the Enterprise platform
|
||||
4. Create a new deployment with a unique identifier
|
||||
|
||||
On successful creation, you'll see a message like:
|
||||
```shell
|
||||
Deployment created successfully!
|
||||
Name: your_project_name
|
||||
Deployment ID: 01234567-89ab-cdef-0123-456789abcdef
|
||||
Current Status: Deploy Enqueued
|
||||
```
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Monitor Deployment Progress">
|
||||
|
||||
Track the deployment status with:
|
||||
|
||||
```bash
|
||||
crewai deploy status
|
||||
```
|
||||
|
||||
For detailed logs of the build process:
|
||||
|
||||
```bash
|
||||
crewai deploy logs
|
||||
```
|
||||
|
||||
<Tip>
|
||||
The first deployment typically takes 10-15 minutes as it builds the container images. Subsequent deployments are much faster.
|
||||
</Tip>
|
||||
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Additional CLI Commands
|
||||
|
||||
The CrewAI CLI offers several commands to manage your deployments:
|
||||
|
||||
```bash
|
||||
# List all your deployments
|
||||
crewai deploy list
|
||||
|
||||
# Get the status of your deployment

```
|
||||
|
||||
## Option 2: Deploy Directly via Web Interface
|
||||
|
||||
You can also deploy your crews directly through the CrewAI Enterprise web interface by connecting your GitHub account. This approach doesn't require using the CLI on your local machine.
|
||||
|
||||
<Steps>
|
||||
|
||||
<Step title="Pushing to GitHub">
|
||||
|
||||
You need to push your crew to a GitHub repository. If you haven't created a crew yet, you can [follow this tutorial](/quickstart).
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Connecting GitHub to CrewAI Enterprise">
|
||||
|
||||
1. Log in to [CrewAI Enterprise](https://app.crewai.com)
|
||||
2. Click on the button "Connect GitHub"
|
||||

|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Select the Repository">
|
||||
|
||||
After connecting your GitHub account, you'll be able to select which repository to deploy:

|
||||

|
||||
</Frame>
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Set Environment Variables">
|
||||
|
||||
Before deploying, you'll need to set up your environment variables to connect to your LLM provider or other services:
|
||||
|
||||
1. You can add variables individually or in bulk
|
||||
2. Enter your environment variables in `KEY=VALUE` format (one per line)
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
</Step>
|
||||
|
||||
<Step title="Deploy Your Crew">
|
||||
|
||||
1. Click the "Deploy" button to start the deployment process
|
||||
2. You can monitor the progress through the progress bar
|
||||
3. The first deployment typically takes around 10-15 minutes; subsequent deployments will be faster
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
Once deployment is complete, you'll see:
|
||||
- Your crew's unique URL
|
||||
- A Bearer token to protect your crew API
|
||||
- A "Delete" button if you need to remove the deployment
|
||||
|
||||
</Step>
|
||||
|
||||
</Steps>
|
||||
|
||||
## ⚠️ Environment Variable Security Requirements
|
||||
|
||||
<Warning>
|
||||
**Important**: CrewAI Enterprise has security restrictions on environment variable names that can cause deployment failures if not followed.
|
||||
</Warning>
|
||||
|
||||
### Blocked Environment Variable Patterns
|
||||
|
||||
For security reasons, the following environment variable naming patterns are **automatically filtered** and will cause deployment issues:
|
||||
|
||||
**Blocked Patterns:**
|
||||
- Variables ending with `_TOKEN` (e.g., `MY_API_TOKEN`)
|
||||
- Variables ending with `_PASSWORD` (e.g., `DB_PASSWORD`)
|
||||
- Variables ending with `_SECRET` (e.g., `API_SECRET`)
|
||||
- Variables ending with `_KEY` in certain contexts
|
||||
|
||||
**Specific Blocked Variables:**
|
||||
- `GITHUB_USER`, `GITHUB_TOKEN`
|
||||
- `AWS_REGION`, `AWS_DEFAULT_REGION`
|
||||
- Various internal CrewAI system variables
|
||||
|
||||
### Allowed Exceptions
|
||||
|
||||
Some variables are explicitly allowed despite matching blocked patterns:
|
||||
- `AZURE_AD_TOKEN`
|
||||
- `AZURE_OPENAI_AD_TOKEN`
|
||||
- `ENTERPRISE_ACTION_TOKEN`
|
||||
- `CREWAI_ENTEPRISE_TOOLS_TOKEN`
|
||||
|
||||
### How to Fix Naming Issues
|
||||
|
||||
If your deployment fails due to environment variable restrictions:
|
||||
|
||||
```bash
|
||||
# ❌ These will cause deployment failures
|
||||
OPENAI_TOKEN=sk-...
|
||||
DATABASE_PASSWORD=mypassword
|
||||
API_SECRET=secret123
|
||||
|
||||
# ✅ Use these naming patterns instead
|
||||
OPENAI_API_KEY=sk-...
|
||||
DATABASE_CREDENTIALS=mypassword
|
||||
API_CONFIG=secret123
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Use standard naming conventions**: `PROVIDER_API_KEY` instead of `PROVIDER_TOKEN`
|
||||
2. **Test locally first**: Ensure your crew works with the renamed variables
|
||||
3. **Update your code**: Change any references to the old variable names
|
||||
4. **Document changes**: Keep track of renamed variables for your team
|
||||
|
||||
<Tip>
|
||||
If you encounter deployment failures with cryptic environment variable errors, check your variable names against these patterns first.
|
||||
</Tip>
|
||||
|
||||
### Interact with Your Deployed Crew
|
||||
|
||||
Once deployment is complete, you can access your crew through:
|
||||
|
||||
1. **REST API**: The platform generates a unique HTTPS endpoint with these key routes:
|
||||
- `/inputs`: Lists the required input parameters
|
||||
- `/kickoff`: Initiates an execution with provided inputs
|
||||
- `/status/{kickoff_id}`: Checks the execution status
|
||||
|
||||
2. **Web Interface**: Visit [app.crewai.com](https://app.crewai.com) to access:
|
||||
- **Status tab**: View deployment information, API endpoint details, and authentication token
|
||||
- **Run tab**: Visual representation of your crew's structure
|
||||
- **Executions tab**: History of all executions
|
||||
- **Metrics tab**: Performance analytics
|
||||
- **Traces tab**: Detailed execution insights
|
||||
|
||||
### Trigger an Execution
|
||||
|
||||
From the Enterprise dashboard, you can:
|
||||
|
||||
1. Click on your crew's name to open its details
|
||||
2. Select "Trigger Crew" from the management interface
|
||||
3. Enter the required inputs in the modal that appears
|
||||
4. Monitor progress as the execution moves through the pipeline
|
||||
|
||||

Human-In-The-Loop (HITL) is a powerful approach that combines artificial intelligence with human expertise to enhance decision-making and improve task outcomes. This guide shows you how to implement HITL within CrewAI.
|
||||
|
||||
## Setting Up HITL Workflows
|
||||
|
||||
<Steps>
|
||||
<Step title="Configure Your Task">
|
||||
Set up your task with human input enabled:
|
||||
<Frame>
|
||||
<img src="/images/enterprise/crew-human-input.png" alt="Crew Human Input" />
|
||||
</Frame>
|
||||
</Step>
|
||||
|
||||
<Step title="Provide Webhook URL">
|
||||
When kicking off your crew, include a webhook URL for human input:
|
||||
<Frame>
|
||||
<img src="/images/enterprise/crew-webhook-url.png" alt="Crew Webhook URL" />
|
||||
</Frame>
|
||||
</Step>
|
||||
|
||||
<Step title="Receive Webhook Notification">
|
||||
Once the crew completes the task requiring human input, you'll receive a webhook notification containing:
|
||||
- **Execution ID**
|
||||
- **Task ID**
|
||||
- **Task output**
|
||||
</Step>
|
||||
|
||||
<Step title="Review Task Output">
|
||||
The system will pause in the `Pending Human Input` state. Review the task output carefully.
|
||||
</Step>
|
||||
|
||||
<Step title="Submit Human Feedback">
|
||||
Call the resume endpoint of your crew with the following information:
|
||||
<Frame>
|
||||
<img src="/images/enterprise/crew-resume-endpoint.png" alt="Crew Resume Endpoint" />
|
||||
</Frame>
|
||||
<Warning>
|
||||
**Feedback Impact on Task Execution**:
|
||||
It's crucial to exercise care when providing feedback, as the entire feedback content will be incorporated as additional context for further task executions.
|
||||
</Warning>
|
||||
This means:
|
||||
- All information in your feedback becomes part of the task's context.
|
||||
- Irrelevant details may negatively influence it.
|
||||
- Concise, relevant feedback helps maintain task focus and efficiency.
|
||||
- Always review your feedback carefully before submission to ensure it contains only pertinent information that will positively guide the task's execution.
|
||||
</Step>
|
||||
<Step title="Handle Negative Feedback">
|
||||
If you provide negative feedback:
|
||||
- The crew will retry the task with added context from your feedback.
|
||||
- You'll receive another webhook notification for further review.
|
||||
- Repeat steps 4-6 until satisfied.
|
||||
</Step>
|
||||
|
||||
<Step title="Execution Continuation">
|
||||
When you submit positive feedback, the execution will proceed to the next steps.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Best Practices
|
||||
|
||||
- **Be Specific**: Provide clear, actionable feedback that directly addresses the task at hand
|
||||
- **Stay Relevant**: Only include information that will help improve the task execution
|
||||
- **Be Timely**: Respond to HITL prompts promptly to avoid workflow delays
|
||||
- **Review Carefully**: Double-check your feedback before submitting to ensure accuracy
|
||||
|
||||
## Common Use Cases
|
||||
|
||||
HITL workflows are particularly valuable for:
|
||||
- Quality assurance and validation
|
||||
- Complex decision-making scenarios
|
||||
- Sensitive or high-stakes operations
|
||||
- Creative tasks requiring human judgment
|
||||
- Compliance and regulatory reviews

### Step 3: Monitor Execution Progress
|
||||
|
||||
After initiating the execution:
|
||||
|
||||
1. You'll receive a response containing a `kickoff_id` - **copy this ID**
|
||||
2. This ID is essential for tracking your execution
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
### Step 4: Check Execution Status
|
||||
|
||||
To monitor the progress of your execution:
|
||||
|
||||
1. Click the "Status" endpoint in the Test Endpoints section
|
||||
2. Paste the `kickoff_id` into the designated field
|
||||
3. Click the "Get Status" button
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
The status response will show:
|
||||
- Current execution state (`running`, `completed`, etc.)
|
||||
- Details about which tasks are in progress
|
||||
- Any outputs produced so far
|
||||
|
||||
### Step 5: View Final Results
|
||||
|
||||
Once execution is complete:
|
||||
|
||||
1. The status will change to `completed`
|
||||
2. You can view the full execution results and outputs
|
||||
3. For a more detailed view, check the `Executions` tab in the crew detail page
|
||||
|
||||
## Method 2: Using the API
|
||||
|
||||
You can also kickoff crews programmatically using the CrewAI Enterprise REST API.
|
||||
|
||||
### Authentication
|
||||
|
||||
All API requests require a bearer token for authentication:
|
||||
|
||||
```bash
|
||||
curl -H "Authorization: Bearer YOUR_CREW_TOKEN" https://your-crew-url.crewai.com
|
||||
```
|
||||
|
||||
Your bearer token is available on the Status tab of your crew's detail page.
|
||||
|
||||
### Checking Crew Health
|
||||
|
||||
Before executing operations, you can verify that your crew is running properly:
|
||||
|
||||
```bash
|
||||
curl -H "Authorization: Bearer YOUR_CREW_TOKEN" https://your-crew-url.crewai.com
|
||||
```
|
||||
|
||||
A successful response will return a message indicating the crew is operational:
|
||||
|
||||
```
|
||||
Healthy%
|
||||
```
|
||||
|
||||
### Step 1: Retrieve Required Inputs
|
||||
|
||||
First, determine what inputs your crew requires:
|
||||
|
||||
```bash
|
||||
curl -X GET \
|
||||
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
|
||||
https://your-crew-url.crewai.com/inputs
|
||||
```
|
||||
|
||||
The response will be a JSON object containing an array of required input parameters, for example:
|
||||
|
||||
```json
|
||||
{"inputs":["topic","current_year"]}
|
||||
```
|
||||
|
||||
This example shows that this particular crew requires two inputs: `topic` and `current_year`.
|
||||
|
||||
### Step 2: Kickoff Execution
|
||||
|
||||
Initiate execution by providing the required inputs:
|
||||
|
||||
```bash
|
||||
curl -X POST \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
|
||||
-d '{"inputs": {"topic": "AI Agent Frameworks", "current_year": "2025"}}' \
|
||||
https://your-crew-url.crewai.com/kickoff
|
||||
```
|
||||
|
||||
The response will include a `kickoff_id` that you'll need for tracking:
|
||||
|
||||
```json
|
||||
{"kickoff_id":"abcd1234-5678-90ef-ghij-klmnopqrstuv"}
|
||||
```
|
||||
|
||||
### Step 3: Check Execution Status
|
||||
|
||||
Monitor the execution progress using the kickoff_id:
|
||||
|
||||
```bash
|
||||
curl -X GET \
|
||||
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
|
||||
https://your-crew-url.crewai.com/status/abcd1234-5678-90ef-ghij-klmnopqrstuv
|
||||
```
|
||||
|
||||
## Handling Executions
|
||||
|
||||
### Long-Running Executions
|
||||
|
||||
For executions that may take a long time:
|
||||
|
||||
1. Consider implementing a polling mechanism to check status periodically
|
||||
2. Use webhooks (if available) for notification when execution completes
|
||||
3. Implement error handling for potential timeouts
|
||||
|
||||
### Execution Context
|
||||
|
||||
The execution context includes:
|
||||
|
||||
- Inputs provided at kickoff
|
||||
- Environment variables configured during deployment
|
||||
- Any state maintained between tasks
|
||||
|
||||
### Debugging Failed Executions
|
||||
|
||||
If an execution fails:
|
||||
|
||||
1. Check the "Executions" tab for detailed logs
|
||||
2. Review the "Traces" tab for step-by-step execution details
|
||||
3. Look for LLM responses and tool usage in the trace details

||||
<img src="/images/enterprise/export-react-component.png" alt="Export React Component" />
|
||||
</Frame>
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Setting Up Your React Environment
|
||||
|
||||
To run this React component locally, you'll need to set up a React development environment and integrate this component into a React project.
|
||||
|
||||
<Steps>
|
||||
<Step title="Install Node.js">
|
||||
- Download and install Node.js from the official website: https://nodejs.org/
|
||||
- Choose the LTS (Long Term Support) version for stability.
|
||||
</Step>
|
||||
|
||||
<Step title="Create a new React project">
|
||||
- Open Command Prompt or PowerShell
|
||||
- Navigate to the directory where you want to create your project
|
||||
- Run the following command to create a new React project:
|
||||
|
||||
```bash
|
||||
npx create-react-app my-crew-app
|
||||
```
|
||||
- Change into the project directory:
|
||||
|
||||
```bash
|
||||
cd my-crew-app
|
||||
```
|
||||
</Step>
|
||||
|
||||
<Step title="Install necessary dependencies">
|
||||
```bash
|
||||
npm install react-dom
|
||||
```
|
||||
</Step>
|
||||
|
||||
<Step title="Create the CrewLead component">
|
||||
- Move the downloaded file `CrewLead.jsx` into the `src` folder of your project,
|
||||
</Step>
|
||||
|
||||
<Step title="Modify your App.js to use the CrewLead component">
|
||||
- Open `src/App.js`
|
||||
- Replace its contents with something like this:
|
||||
|
||||
```jsx
|
||||
import React from 'react';
|
||||
import CrewLead from './CrewLead';
|
||||
|
||||
function App() {
|
||||
return (
|
||||
<div className="App">
|
||||
<CrewLead baseUrl="YOUR_API_BASE_URL" bearerToken="YOUR_BEARER_TOKEN" />
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
export default App;
|
||||
```
|
||||
- Replace `YOUR_API_BASE_URL` and `YOUR_BEARER_TOKEN` with the actual values for your API.
|
||||
</Step>
|
||||
|
||||
<Step title="Start the development server">
|
||||
- In your project directory, run:
|
||||
|
||||
```bash
|
||||
npm start
|
||||
```
|
||||
- This will start the development server, and your default web browser should open automatically to http://localhost:3000, where you'll see your React app running.
|
||||
</Step>
|
||||
</Steps>
|
||||
|
||||
## Customization
|
||||
|
||||
You can then customise the `CrewLead.jsx` to add color, title etc

|
||||
|
||||
<Note>
|
||||
After deploying your crew to CrewAI Enterprise, you may need to make updates to the code, security settings, or configuration.
|
||||
This guide explains how to perform these common update operations.
|
||||
</Note>
|
||||
|
||||
## Why Update Your Crew?
|
||||
|
||||
CrewAI won't automatically pick up GitHub updates by default, so you'll need to manually trigger updates, unless you checked the `Auto-update` option when deploying your crew.
|
||||
|
||||
There are several reasons you might want to update your crew deployment:
|
||||
- You want to update the code with a latest commit you pushed to GitHub
|
||||
- You want to reset the bearer token for security reasons
|
||||
- You want to update environment variables
|
||||
|
||||
## 1. Updating Your Crew Code for a Latest Commit
|
||||
|
||||
When you've pushed new commits to your GitHub repository and want to update your deployment:
|
||||
|
||||
1. Navigate to your crew in the CrewAI Enterprise platform
|
||||
2. Click on the `Re-deploy` button on your crew details page
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
This will trigger an update that you can track using the progress bar. The system will pull the latest code from your repository and rebuild your deployment.
|
||||
|
||||
## 2. Resetting Bearer Token
|
||||
|
||||
If you need to generate a new bearer token (for example, if you suspect the current token might have been compromised):
|
||||
|
||||
1. Navigate to your crew in the CrewAI Enterprise platform
|
||||
2. Find the `Bearer Token` section
|
||||
3. Click the `Reset` button next to your current token
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
<Warning>
|
||||
Resetting your bearer token will invalidate the previous token immediately. Make sure to update any applications or scripts that are using the old token.
|
||||
</Warning>
|
||||
|
||||
## 3. Updating Environment Variables
|
||||
|
||||
To update the environment variables for your crew:
|
||||
|
||||
1. First access the deployment page by clicking on your crew's name
|
||||
|
||||
<Frame>
|
||||

|
||||
</Frame>
|
||||
|
||||
2. Locate the `Environment Variables` section (you will need to click the `Settings` icon to access it)
|
||||
3. Edit the existing variables or add new ones in the fields provided
|
||||
4. Click the `Update` button next to each variable you modify

CrewAI Enterprise allows you to automate your workflow using webhooks. This article will guide you through the process of setting up and using webhooks to kickoff your crew execution, with a focus on integration with ActivePieces, a workflow automation platform similar to Zapier and Make.com.
|
||||
|
||||
## Setting Up Webhooks
|
||||
|
||||
<Steps>
|
||||
<Step title="Accessing the Kickoff Interface">
|
||||
- Navigate to the CrewAI Enterprise dashboard
|
||||
- Look for the `/kickoff` section, which is used to start the crew execution
|
||||
<Frame>
|
||||
<img src="/images/enterprise/kickoff-interface.png" alt="Kickoff Interface" />
|
||||
</Frame>
|
||||
</Step>
|
||||
|
||||
<Step title="Configuring the JSON Content">
|
||||
In the JSON Content section, you'll need to provide the following information:
|
||||
|
||||
- **inputs**: A JSON object containing:
|
||||
- `company`: The name of the company (e.g., "tesla")
|
||||
- `product_name`: The name of the product (e.g., "crewai")
|
||||
- `form_response`: The type of response (e.g., "financial")
|
||||
- `icp_description`: A brief description of the Ideal Customer Profile
|
||||
- `product_description`: A short description of the product
|
||||
- `taskWebhookUrl`, `stepWebhookUrl`, `crewWebhookUrl`: URLs for various webhook endpoints (ActivePieces, Zapier, Make.com or another compatible platform)
|
||||
</Step>
|
||||
|
||||
<Step title="Integrating with ActivePieces">
|
||||
In this example we will be using ActivePieces. You can use other platforms such as Zapier and Make.com
|
||||
|
||||
To integrate with ActivePieces:
|
||||
|
||||
1. Set up a new flow in ActivePieces
|
||||
2. Add a trigger (e.g., `Every Day` schedule)
|
||||
<Frame>
|
||||
<img src="/images/enterprise/activepieces-trigger.png" alt="ActivePieces Trigger" />
|
||||
</Frame>
|
||||
|
||||
3. Add an HTTP action step
|
||||
- Set the action to `Send HTTP request`
|
||||
- Use `POST` as the method
|
||||
- Set the URL to your CrewAI Enterprise kickoff endpoint
|
||||
- Add necessary headers (e.g., `Bearer Token`)
|
||||
<Frame>
|
||||
<img src="/images/enterprise/activepieces-headers.png" alt="ActivePieces Headers" />
|
||||
</Frame>
|
||||
|
||||
- In the body, include the JSON content as configured in step 2
|
||||
<Frame>
|
||||
<img src="/images/enterprise/activepieces-body.png" alt="ActivePieces Body" />
|
||||
</Frame>
|
||||
|
||||
- The crew will then kickoff at the pre-defined time.
|
||||
</Step>
|
||||
|
||||
<Step title="Setting Up the Webhook">
|
||||
1. Create a new flow in ActivePieces and name it
|
||||
<Frame>
|
||||
<img src="/images/enterprise/activepieces-flow.png" alt="ActivePieces Flow" />
|
||||
</Frame>
|
||||
|
||||
2. Add a webhook step as the trigger:
|
||||
- Select `Catch Webhook` as the trigger type
|
||||
- This will generate a unique URL that will receive HTTP requests and trigger your flow
|
||||
<Frame>
|
||||
<img src="/images/enterprise/activepieces-webhook.png" alt="ActivePieces Webhook" />
|
||||
</Frame>
|
||||
|
||||
- Configure the email to use crew webhook body text

<AccordionGroup>
|
||||
<Accordion title="How is task execution handled in the hierarchical process?">
|
||||
In the hierarchical process, a manager agent is automatically created and coordinates the workflow, delegating tasks and validating outcomes for streamlined and effective execution. The manager agent utilizes tools to facilitate task delegation and execution by agents under the manager's guidance. The manager LLM is crucial for the hierarchical process and must be set up correctly for proper function.
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="Where can I get the latest CrewAI documentation?">
|
||||
The most up-to-date documentation for CrewAI is available on our official documentation website: https://docs.crewai.com/
|
||||
<Card href="https://docs.crewai.com/" icon="books">CrewAI Docs</Card>
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What are the key differences between Hierarchical and Sequential Processes in CrewAI?">
|
||||
#### Hierarchical Process:
|
||||
- Tasks are delegated and executed based on a structured chain of command
|
||||
- A manager language model (`manager_llm`) must be specified for the manager agent
|
||||
- Manager agent oversees task execution, planning, delegation, and validation
|
||||
- Tasks are not pre-assigned; the manager allocates tasks to agents based on their capabilities
|
||||
|
||||
#### Sequential Process:
|
||||
- Tasks are executed one after another, ensuring tasks are completed in an orderly progression
|
||||
- Output of one task serves as context for the next
|
||||
- Task execution follows the predefined order in the task list
|
||||
|
||||
#### Which Process is Better for Complex Projects?
|
||||
The hierarchical process is better suited for complex projects because it allows for:
|
||||
- **Dynamic task allocation and delegation**: Manager agent can assign tasks based on agent capabilities
|
||||
- **Structured validation and oversight**: Manager agent reviews task outputs and ensures completion
|
||||
- **Complex task management**: Precise control over tool availability at the agent level
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What are the benefits of using memory in the CrewAI framework?">
|
||||
- **Adaptive Learning**: Crews become more efficient over time, adapting to new information and refining their approach to tasks
|
||||
- **Enhanced Personalization**: Memory enables agents to remember user preferences and historical interactions, leading to personalized experiences
|
||||
- **Improved Problem Solving**: Access to a rich memory store aids agents in making more informed decisions, drawing on past learnings and contextual insights
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What is the purpose of setting a maximum RPM limit for an agent?">
|
||||
Setting a maximum RPM limit for an agent prevents the agent from making too many requests to external services, which can help to avoid rate limits and improve performance.
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What role does human input play in the execution of tasks within a CrewAI crew?">
|
||||
Human input allows agents to request additional information or clarification when necessary. This feature is crucial in complex decision-making processes or when agents require more details to complete a task effectively.
|
||||
|
||||
To integrate human input into agent execution, set the `human_input` flag in the task definition. When enabled, the agent prompts the user for input before delivering its final answer. This input can provide extra context, clarify ambiguities, or validate the agent's output.
|
||||
|
||||
For detailed implementation guidance, see our [Human-in-the-Loop guide](/how-to/human-in-the-loop).
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What advanced customization options are available for tailoring and enhancing agent behavior and capabilities in CrewAI?">
|
||||
CrewAI provides a range of advanced customization options:
|
||||
|
||||
- **Language Model Customization**: Agents can be customized with specific language models (`llm`) and function-calling language models (`function_calling_llm`)
|
||||
- **Performance and Debugging Settings**: Adjust an agent's performance and monitor its operations
|
||||
- **Verbose Mode**: Enables detailed logging of an agent's actions, useful for debugging and optimization
|
||||
- **RPM Limit**: Sets the maximum number of requests per minute (`max_rpm`)
|
||||
- **Maximum Iterations**: The `max_iter` attribute allows users to define the maximum number of iterations an agent can perform for a single task
|
||||
- **Delegation and Autonomy**: Control an agent's ability to delegate or ask questions with the `allow_delegation` attribute (default: True)
|
||||
- **Human Input Integration**: Agents can request additional information or clarification when necessary
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="In what scenarios is human input particularly useful in agent execution?">
|
||||
Human input is particularly useful when:
|
||||
- **Agents require additional information or clarification**: When agents encounter ambiguity or incomplete data
|
||||
- **Agents need to make complex or sensitive decisions**: Human input can assist in ethical or nuanced decision-making
|
||||
- **Oversight and validation of agent output**: Human input can help validate results and prevent errors
|
||||
- **Customizing agent behavior**: Human input can provide feedback to refine agent responses over time
|
||||
- **Identifying and resolving errors or limitations**: Human input helps address agent capability gaps
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="What are the different types of memory that are available in crewAI?">
|
||||
The different types of memory available in CrewAI are:
|
||||
- **Short-term memory**: Temporary storage for immediate context
|
||||
- **Long-term memory**: Persistent storage for learned patterns and information
|
||||
- **Entity memory**: Focused storage for specific entities and their attributes
|
||||
- **Contextual memory**: Memory that maintains context across interactions

<Accordion title="How can I create custom tools for my CrewAI agents?">
|
||||
You can create custom tools by subclassing the `BaseTool` class provided by CrewAI or by using the tool decorator. Subclassing involves defining a new class that inherits from `BaseTool`, specifying the name, description, and the `_run` method for operational logic. The tool decorator allows you to create a `Tool` object directly with the required attributes and a functional logic.

|
||||
|
||||
## Why Customize Prompts?
|
||||
|
||||
Although CrewAI's default prompts work well for many scenarios, low-level customization opens the door to significantly more flexible and powerful agent behavior. Here's why you might want to take advantage of this deeper control:
|
||||
|
||||
1. **Optimize for specific LLMs** – Different models (such as GPT-4, Claude, or Llama) thrive with prompt formats tailored to their unique architectures.
|
||||
2. **Change the language** – Build agents that operate exclusively in languages beyond English, handling nuances with precision.
|
||||
3. **Specialize for complex domains** – Adapt prompts for highly specialized industries like healthcare, finance, or legal.
|
||||
4. **Adjust tone and style** – Make agents more formal, casual, creative, or analytical.
|
||||
5. **Support super custom use cases** – Utilize advanced prompt structures and formatting to meet intricate, project-specific requirements.
|
||||
|
||||
This guide explores how to tap into CrewAI's prompts at a lower level, giving you fine-grained control over how agents think and interact.
|
||||
|
||||
## Understanding CrewAI's Prompt System
|
||||
|
||||
Under the hood, CrewAI employs a modular prompt system that you can customize extensively:
|
||||
|
||||
- **Agent templates** – Govern each agent's approach to their assigned role.
|
||||
- **Prompt slices** – Control specialized behaviors such as tasks, tool usage, and output structure.
|
||||
- **Error handling** – Direct how agents respond to failures, exceptions, or timeouts.
|
||||
- **Tool-specific prompts** – Define detailed instructions for how tools are invoked or utilized.
|
||||
|
||||
Check out the [original prompt templates in CrewAI's repository](https://github.com/crewAIInc/crewAI/blob/main/src/crewai/translations/en.json) to see how these elements are organized. From there, you can override or adapt them as needed to unlock advanced behaviors.
|
||||
|
||||
## Understanding Default System Instructions
|
||||
|
||||
<Warning>
|
||||
**Production Transparency Issue**: CrewAI automatically injects default instructions into your prompts that you might not be aware of. This section explains what's happening under the hood and how to gain full control.
|
||||
</Warning>
|
||||
|
||||
When you define an agent with `role`, `goal`, and `backstory`, CrewAI automatically adds additional system instructions that control formatting and behavior. Understanding these default injections is crucial for production systems where you need full prompt transparency.
|
||||
|
||||
### What CrewAI Automatically Injects
|
||||
|
||||
Based on your agent configuration, CrewAI adds different default instructions:
|
||||
|
||||
#### For Agents Without Tools
|
||||
```text
|
||||
"I MUST use these formats, my job depends on it!"
|
||||
```
|
||||
|
||||
#### For Agents With Tools
|
||||
```text
|
||||
"IMPORTANT: Use the following format in your response:
|
||||
|
||||
Thought: you should always think about what to do
|
||||
Action: the action to take, only one name of [tool_names]
|
||||
Action Input: the input to the action, just a simple JSON object...
|
||||
```
|
||||
|
||||
#### For Structured Outputs (JSON/Pydantic)
|
||||
```text
|
||||
"Ensure your final answer contains only the content in the following format: {output_format}
|
||||
Ensure the final output does not include any code block markers like ```json or ```python."
|
||||
```
|
||||
|
||||
### Viewing the Complete System Prompt
|
||||
|
||||
To see exactly what prompt is being sent to your LLM, you can inspect the generated prompt:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task
|
||||
from crewai.utilities.prompts import Prompts
|
||||
|
||||
# Create your agent
|
||||
agent = Agent(
|
||||
role="Data Analyst",
|
||||
goal="Analyze data and provide insights",
|
||||
backstory="You are an expert data analyst with 10 years of experience.",
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Create a sample task
|
||||
task = Task(
|
||||
description="Analyze the sales data and identify trends",
|
||||
expected_output="A detailed analysis with key insights and trends",
|
||||
agent=agent
|
||||
)
|
||||
|
||||
# Create the prompt generator
|
||||
prompt_generator = Prompts(
|
||||
agent=agent,
|
||||
has_tools=len(agent.tools) > 0,
|
||||
use_system_prompt=agent.use_system_prompt
|
||||
)
|
||||
|
||||
# Generate and inspect the actual prompt
|
||||
generated_prompt = prompt_generator.task_execution()
|
||||
|
||||
# Print the complete system prompt that will be sent to the LLM
|
||||
if "system" in generated_prompt:
|
||||
print("=== SYSTEM PROMPT ===")
|
||||
print(generated_prompt["system"])
|
||||
print("\n=== USER PROMPT ===")
|
||||
print(generated_prompt["user"])
|
||||
else:
|
||||
print("=== COMPLETE PROMPT ===")
|
||||
print(generated_prompt["prompt"])
|
||||
|
||||
# You can also see how the task description gets formatted
|
||||
print("\n=== TASK CONTEXT ===")
|
||||
print(f"Task Description: {task.description}")
|
||||
print(f"Expected Output: {task.expected_output}")
|
||||
```
|
||||
|
||||
### Overriding Default Instructions
|
||||
|
||||
You have several options to gain full control over the prompts:
|
||||
|
||||
#### Option 1: Custom Templates (Recommended)
|
||||
```python
|
||||
from crewai import Agent
|
||||
|
||||
# Define your own system template without default instructions
|
||||
custom_system_template = """You are {role}. {backstory}
|
||||
Your goal is: {goal}
|
||||
|
||||
Respond naturally and conversationally. Focus on providing helpful, accurate information."""
|
||||
|
||||
custom_prompt_template = """Task: {input}
|
||||
|
||||
Please complete this task thoughtfully."""
|
||||
|
||||
agent = Agent(
|
||||
role="Research Assistant",
|
||||
goal="Help users find accurate information",
|
||||
backstory="You are a helpful research assistant.",
|
||||
system_template=custom_system_template,
|
||||
prompt_template=custom_prompt_template,
|
||||
use_system_prompt=True # Use separate system/user messages
|
||||
)
|
||||
```
|
||||
|
||||
#### Option 2: Custom Prompt File
|
||||
Create a `custom_prompts.json` file to override specific prompt slices:
|
||||
|
||||
```json
|
||||
{
|
||||
"slices": {
|
||||
"no_tools": "\nProvide your best answer in a natural, conversational way.",
|
||||
"tools": "\nYou have access to these tools: {tools}\n\nUse them when helpful, but respond naturally.",
|
||||
"formatted_task_instructions": "Format your response as: {output_format}"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then use it in your crew:
|
||||
|
||||
```python
|
||||
crew = Crew(
|
||||
agents=[agent],
|
||||
tasks=[task],
|
||||
prompt_file="custom_prompts.json",
|
||||
verbose=True
|
||||
)
|
||||
```
|
||||
|
||||
#### Option 3: Disable System Prompts for o1 Models
|
||||
```python
|
||||
agent = Agent(
|
||||
role="Analyst",
|
||||
goal="Analyze data",
|
||||
backstory="Expert analyst",
|
||||
use_system_prompt=False # Disables system prompt separation
|
||||
)
|
||||
```
|
||||
|
||||
### Debugging with Observability Tools
|
||||
|
||||
For production transparency, integrate with observability platforms to monitor all prompts and LLM interactions. This allows you to see exactly what prompts (including default instructions) are being sent to your LLMs.
|
||||
|
||||
See our [Observability documentation](/how-to/observability) for detailed integration guides with various platforms including Langfuse, MLflow, Weights & Biases, and custom logging solutions.
|
||||
|
||||
### Best Practices for Production
|
||||
|
||||
1. **Always inspect generated prompts** before deploying to production
|
||||
2. **Use custom templates** when you need full control over prompt content
|
||||
3. **Integrate observability tools** for ongoing prompt monitoring (see [Observability docs](/how-to/observability))
|
||||
4. **Test with different LLMs** as default instructions may work differently across models
|
||||
5. **Document your prompt customizations** for team transparency
|
||||
|
||||
<Tip>
|
||||
The default instructions exist to ensure consistent agent behavior, but they can interfere with domain-specific requirements. Use the customization options above to maintain full control over your agent's behavior in production systems.
|
||||
</Tip>
|
||||
|
||||
## Best Practices for Managing Prompt Files
|
||||
|
||||
When engaging in low-level prompt customization, follow these guidelines to keep things organized and maintainable:
|
||||
|
||||
1. **Keep files separate** – Store your customized prompts in dedicated JSON files outside your main codebase.
|
||||
2. **Version control** – Track changes within your repository, ensuring clear documentation of prompt adjustments over time.
|
||||
3. **Organize by model or language** – Use naming schemes like `prompts_llama.json` or `prompts_es.json` to quickly identify specialized configurations.
|
||||
4. **Document changes** – Provide comments or maintain a README detailing the purpose and scope of your customizations.
|
||||
5. **Minimize alterations** – Only override the specific slices you genuinely need to adjust, keeping default functionality intact for everything else.
|
||||
|
||||
## The Simplest Way to Customize Prompts
|
||||
|
||||
One straightforward approach is to create a JSON file for the prompts you want to override and then point your Crew at that file:
|
||||
|
||||
1. Craft a JSON file with your updated prompt slices.
|
||||
2. Reference that file via the `prompt_file` parameter in your Crew.
|
||||
|
||||
CrewAI then merges your customizations with the defaults, so you don't have to redefine every prompt. Here's how:
|
||||
|
||||
### Example: Basic Prompt Customization
|
||||
|
||||
Create a `custom_prompts.json` file with the prompts you want to modify. Ensure you list all top-level prompts it should contain, not just your changes:
|
||||
|
||||
```json
|
||||
{
|
||||
"slices": {
|
||||
"format": "When responding, follow this structure:\n\nTHOUGHTS: Your step-by-step thinking\nACTION: Any tool you're using\nRESULT: Your final answer or conclusion"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then integrate it like so:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
|
||||
# Create agents and tasks as normal
|
||||
researcher = Agent(
|
||||
role="Research Specialist",
|
||||
goal="Find information on quantum computing",
|
||||
backstory="You are a quantum physics expert",
|
||||
verbose=True
|
||||
)
|
||||
|
||||
research_task = Task(
|
||||
description="Research quantum computing applications",
|
||||
expected_output="A summary of practical applications",
|
||||
agent=researcher
|
||||
)
|
||||
|
||||
# Create a crew with your custom prompt file
|
||||
crew = Crew(
|
||||
agents=[researcher],
|
||||
tasks=[research_task],
|
||||
prompt_file="path/to/custom_prompts.json",
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Run the crew
|
||||
result = crew.kickoff()
|
||||
```
|
||||
|
||||
With these few edits, you gain low-level control over how your agents communicate and solve tasks.
|
||||
|
||||
## Optimizing for Specific Models
|
||||
|
||||
Different models thrive on differently structured prompts. Making deeper adjustments can significantly boost performance by aligning your prompts with a model's nuances.
|
||||
|
||||
### Example: Llama 3.3 Prompting Template
|
||||
|
||||
For instance, when dealing with Meta's Llama 3.3, deeper-level customization may reflect the recommended structure described at:
|
||||
https://www.llama.com/docs/model-cards-and-prompt-formats/llama3_1/#prompt-template
|
||||
|
||||
Here's an example to highlight how you might fine-tune an Agent to leverage Llama 3.3 in code:
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task, Process
|
||||
from crewai_tools import DirectoryReadTool, FileReadTool
|
||||
|
||||
# Define templates for system, user (prompt), and assistant (response) messages
|
||||
system_template = """<|begin_of_text|><|start_header_id|>system<|end_header_id|>{{ .System }}<|eot_id|>"""
|
||||
prompt_template = """<|start_header_id|>user<|end_header_id|>{{ .Prompt }}<|eot_id|>"""
|
||||
response_template = """<|start_header_id|>assistant<|end_header_id|>{{ .Response }}<|eot_id|>"""
|
||||
|
||||
# Create an Agent using Llama-specific layouts
|
||||
principal_engineer = Agent(
|
||||
role="Principal Engineer",
|
||||
goal="Oversee AI architecture and make high-level decisions",
|
||||
backstory="You are the lead engineer responsible for critical AI systems",
|
||||
verbose=True,
|
||||
llm="groq/llama-3.3-70b-versatile", # Using the Llama 3 model
|
||||
system_template=system_template,
|
||||
prompt_template=prompt_template,
|
||||
response_template=response_template,
|
||||
tools=[DirectoryReadTool(), FileReadTool()]
|
||||
)
|
||||
|
||||
# Define a sample task
|
||||
engineering_task = Task(
|
||||
description="Review AI implementation files for potential improvements",
|
||||
expected_output="A summary of key findings and recommendations",
|
||||
agent=principal_engineer
|
||||
)
|
||||
|
||||
# Create a Crew for the task
|
||||
llama_crew = Crew(
|
||||
agents=[principal_engineer],
|
||||
tasks=[engineering_task],
|
||||
process=Process.sequential,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Execute the crew
|
||||
result = llama_crew.kickoff()
|
||||
print(result.raw)
|
||||
```
|
||||
|
||||
Through this deeper configuration, you can exercise comprehensive, low-level control over your Llama-based workflows without needing a separate JSON file.
|
||||
|
||||
## Conclusion
|
||||
|
||||
Low-level prompt customization in CrewAI opens the door to super custom, complex use cases. By establishing well-organized prompt files (or direct inline templates), you can accommodate various models, languages, and specialized domains. This level of flexibility ensures you can craft precisely the AI behavior you need, all while knowing CrewAI still provides reliable defaults when you don't override them.
|
||||
|
||||
<Check>
|
||||
You now have the foundation for advanced prompt customizations in CrewAI. Whether you're adapting for model-specific structures or domain-specific constraints, this low-level approach lets you shape agent interactions in highly specialized ways.

description: Learn how to use CrewAI's fingerprinting system to uniquely identify and track components throughout their lifecycle.
|
||||
icon: fingerprint
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Fingerprints in CrewAI provide a way to uniquely identify and track components throughout their lifecycle. Each `Agent`, `Crew`, and `Task` automatically receives a unique fingerprint when created, which cannot be manually overridden.
|
||||
|
||||
These fingerprints can be used for:
|
||||
- Auditing and tracking component usage
|
||||
- Ensuring component identity integrity
|
||||
- Attaching metadata to components
|
||||
- Creating a traceable chain of operations
|
||||
|
||||
## How Fingerprints Work
|
||||
|
||||
A fingerprint is an instance of the `Fingerprint` class from the `crewai.security` module. Each fingerprint contains:
|
||||
|
||||
- A UUID string: A unique identifier for the component that is automatically generated and cannot be manually set
|
||||
- A creation timestamp: When the fingerprint was generated, automatically set and cannot be manually modified
|
||||
- Metadata: A dictionary of additional information that can be customized
|
||||
|
||||
Fingerprints are automatically generated and assigned when a component is created. Each component exposes its fingerprint through a read-only property.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
### Accessing Fingerprints
|
||||
|
||||
```python
|
||||
from crewai import Agent, Crew, Task
|
||||
|
||||
# Create components - fingerprints are automatically generated
|
||||
agent = Agent(
|
||||
role="Data Scientist",
|
||||
goal="Analyze data",
|
||||
backstory="Expert in data analysis"
|
||||
)
|
||||
|
||||
crew = Crew(
|
||||
agents=[agent],
|
||||
tasks=[]
|
||||
)
|
||||
|
||||
task = Task(
|
||||
description="Analyze customer data",
|
||||
expected_output="Insights from data analysis",
|
||||
agent=agent
|
||||
)
|
||||
|
||||
# Access the fingerprints
|
||||
agent_fingerprint = agent.fingerprint
|
||||
crew_fingerprint = crew.fingerprint
|
||||
task_fingerprint = task.fingerprint
|
||||
|
||||
# Print the UUID strings
|
||||
print(f"Agent fingerprint: {agent_fingerprint.uuid_str}")
|
||||
print(f"Crew fingerprint: {crew_fingerprint.uuid_str}")
|
||||
print(f"Task fingerprint: {task_fingerprint.uuid_str}")
|
||||
```
|
||||
|
||||
### Working with Fingerprint Metadata
|
||||
|
||||
You can add metadata to fingerprints for additional context:
|
||||
|
||||
```python
|
||||
# Add metadata to the agent's fingerprint
|
||||
agent.security_config.fingerprint.metadata = {
|
||||
"version": "1.0",
|
||||
"department": "Data Science",
|
||||
"project": "Customer Analysis"
|
||||
}
|
||||
|
||||
# Access the metadata
|
||||
print(f"Agent metadata: {agent.fingerprint.metadata}")
|
||||
```
|
||||
|
||||
## Fingerprint Persistence
|
||||
|
||||
Fingerprints are designed to persist and remain unchanged throughout a component's lifecycle. If you modify a component, the fingerprint remains the same:
|
||||
|
||||
```python
|
||||
original_fingerprint = agent.fingerprint.uuid_str
|
||||
|
||||
# Modify the agent
|
||||
agent.goal = "New goal for analysis"
|
||||
|
||||
# The fingerprint remains unchanged
|
||||
assert agent.fingerprint.uuid_str == original_fingerprint
|
||||
```
|
||||
|
||||
## Deterministic Fingerprints
|
||||
|
||||
While you cannot directly set the UUID and creation timestamp, you can create deterministic fingerprints using the `generate` method with a seed:
|
||||
|
||||
```python
|
||||
from crewai.security import Fingerprint
|
||||
|
||||
# Create a deterministic fingerprint using a seed string
|
||||
deterministic_fingerprint = Fingerprint.generate(seed="my-agent-id")
|
||||
|
||||
# The same seed always produces the same fingerprint
|
||||
same_fingerprint = Fingerprint.generate(seed="my-agent-id")
|
||||
assert deterministic_fingerprint.uuid_str == same_fingerprint.uuid_str
|
||||
|
||||
# You can also set metadata
|
||||
custom_fingerprint = Fingerprint.generate(
|
||||
seed="my-agent-id",
|
||||
metadata={"version": "1.0"}
|
||||
)
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Fingerprint Structure
|
||||
|
||||
Each fingerprint has the following structure:
|
||||
|
||||
```python
|
||||
from crewai.security import Fingerprint
|
||||
|
||||
fingerprint = agent.fingerprint
|
||||
|
||||
# UUID string - the unique identifier (auto-generated)

## The Art and Science of Agent Design
|
||||
|
||||
At the heart of CrewAI lies the agent - a specialized AI entity designed to perform specific roles within a collaborative framework. While creating basic agents is simple, crafting truly effective agents that produce exceptional results requires understanding key design principles and best practices.
|
||||
|
||||
This guide will help you master the art of agent design, enabling you to create specialized AI personas that collaborate effectively, think critically, and produce high-quality outputs tailored to your specific needs.
|
||||
|
||||
### Why Agent Design Matters
|
||||
|
||||
The way you define your agents significantly impacts:
|
||||
|
||||
1. **Output quality**: Well-designed agents produce more relevant, high-quality results
|
||||
2. **Collaboration effectiveness**: Agents with complementary skills work together more efficiently
|
||||
3. **Task performance**: Agents with clear roles and goals execute tasks more effectively
|
||||
4. **System scalability**: Thoughtfully designed agents can be reused across multiple crews and contexts
|
||||
|
||||
Let's explore best practices for creating agents that excel in these dimensions.
|
||||
|
||||
## The 80/20 Rule: Focus on Tasks Over Agents
|
||||
|
||||
When building effective AI systems, remember this crucial principle: **80% of your effort should go into designing tasks, and only 20% into defining agents**.
|
||||
|
||||
Why? Because even the most perfectly defined agent will fail with poorly designed tasks, but well-designed tasks can elevate even a simple agent. This means:
|
||||
|
||||
- Spend most of your time writing clear task instructions
|
||||
- Define detailed inputs and expected outputs
|
||||
- Add examples and context to guide execution
|
||||
- Dedicate the remaining time to agent role, goal, and backstory
|
||||
|
||||
This doesn't mean agent design isn't important - it absolutely is. But task design is where most execution failures occur, so prioritize accordingly.
|
||||
|
||||
## Core Principles of Effective Agent Design
|
||||
|
||||
### 1. The Role-Goal-Backstory Framework
|
||||
|
||||
The most powerful agents in CrewAI are built on a strong foundation of three key elements:
|
||||
|
||||
#### Role: The Agent's Specialized Function
|
||||
|
||||
The role defines what the agent does and their area of expertise. When crafting roles:
|
||||
|
||||
- **Be specific and specialized**: Instead of "Writer," use "Technical Documentation Specialist" or "Creative Storyteller"
|
||||
- **Align with real-world professions**: Base roles on recognizable professional archetypes
|
||||
- **Include domain expertise**: Specify the agent's field of knowledge (e.g., "Financial Analyst specializing in market trends")
|
||||
|
||||
**Examples of effective roles:**
|
||||
```yaml
|
||||
role: "Senior UX Researcher specializing in user interview analysis"
|
||||
role: "Full-Stack Software Architect with expertise in distributed systems"
|
||||
role: "Corporate Communications Director specializing in crisis management"
|
||||
```
|
||||
|
||||
#### Goal: The Agent's Purpose and Motivation
|
||||
|
||||
The goal directs the agent's efforts and shapes their decision-making process. Effective goals should:
|
||||
|
||||
- **Be clear and outcome-focused**: Define what the agent is trying to achieve
|
||||
- **Emphasize quality standards**: Include expectations about the quality of work
|
||||
- **Incorporate success criteria**: Help the agent understand what "good" looks like
|
||||
|
||||
**Examples of effective goals:**
|
||||
```yaml
|
||||
goal: "Uncover actionable user insights by analyzing interview data and identifying recurring patterns, unmet needs, and improvement opportunities"
|
||||
goal: "Design robust, scalable system architectures that balance performance, maintainability, and cost-effectiveness"
|
||||
goal: "Craft clear, empathetic crisis communications that address stakeholder concerns while protecting organizational reputation"
|
||||
```
|
||||
|
||||
#### Backstory: The Agent's Experience and Perspective
|
||||
|
||||
The backstory gives depth to the agent, influencing how they approach problems and interact with others. Good backstories:
|
||||
|
||||
- **Establish expertise and experience**: Explain how the agent gained their skills
|
||||
- **Define working style and values**: Describe how the agent approaches their work
|
||||
- **Create a cohesive persona**: Ensure all elements of the backstory align with the role and goal
|
||||
|
||||
**Examples of effective backstories:**
|
||||
```yaml
|
||||
backstory: "You have spent 15 years conducting and analyzing user research for top tech companies. You have a talent for reading between the lines and identifying patterns that others miss. You believe that good UX is invisible and that the best insights come from listening to what users don't say as much as what they do say."
|
||||
|
||||
backstory: "With 20+ years of experience building distributed systems at scale, you've developed a pragmatic approach to software architecture. You've seen both successful and failed systems and have learned valuable lessons from each. You balance theoretical best practices with practical constraints and always consider the maintenance and operational aspects of your designs."
|
||||
|
||||
backstory: "As a seasoned communications professional who has guided multiple organizations through high-profile crises, you understand the importance of transparency, speed, and empathy in crisis response. You have a methodical approach to crafting messages that address concerns while maintaining organizational credibility."
|
||||
```
|
||||
|
||||
### 2. Specialists Over Generalists
|
||||
|
||||
Agents perform significantly better when given specialized roles rather than general ones. A highly focused agent delivers more precise, relevant outputs:
|
||||
|
||||
**Generic (Less Effective):**
|
||||
```yaml
|
||||
role: "Writer"
|
||||
```
|
||||
|
||||
**Specialized (More Effective):**
|
||||
```yaml
|
||||
role: "Technical Blog Writer specializing in explaining complex AI concepts to non-technical audiences"
|
||||
```
|
||||
|
||||
**Specialist Benefits:**
|
||||
- Clearer understanding of expected output
|
||||
- More consistent performance
|
||||
- Better alignment with specific tasks
|
||||
- Improved ability to make domain-specific judgments
|
||||
|
||||
### 3. Balancing Specialization and Versatility
|
||||
|
||||
Effective agents strike the right balance between specialization (doing one thing extremely well) and versatility (being adaptable to various situations):
|
||||
|
||||
- **Specialize in role, versatile in application**: Create agents with specialized skills that can be applied across multiple contexts
|
||||
- **Avoid overly narrow definitions**: Ensure agents can handle variations within their domain of expertise
|
||||
- **Consider the collaborative context**: Design agents whose specializations complement the other agents they'll work with
|
||||
|
||||
### 4. Setting Appropriate Expertise Levels
|
||||
|
||||
The expertise level you assign to your agent shapes how they approach tasks:
|
||||
|
||||
- **Novice agents**: Good for straightforward tasks, brainstorming, or initial drafts
|
||||
- **Intermediate agents**: Suitable for most standard tasks with reliable execution
|
||||
- **Expert agents**: Best for complex, specialized tasks requiring depth and nuance
|
||||
- **World-class agents**: Reserved for critical tasks where exceptional quality is needed
|
||||
|
||||
Choose the appropriate expertise level based on task complexity and quality requirements. For most collaborative crews, a mix of expertise levels often works best, with higher expertise assigned to core specialized functions.
|
||||
|
||||
## Practical Examples: Before and After
|
||||
|
||||
Let's look at some examples of agent definitions before and after applying these best practices:
|
||||
|
||||
### Example 1: Content Creation Agent
|
||||
|
||||
**Before:**
|
||||
```yaml
|
||||
role: "Writer"
|
||||
goal: "Write good content"
|
||||
backstory: "You are a writer who creates content for websites."
|
||||
```
|
||||
|
||||
**After:**
|
||||
```yaml
|
||||
role: "B2B Technology Content Strategist"
|
||||
goal: "Create compelling, technically accurate content that explains complex topics in accessible language while driving reader engagement and supporting business objectives"
|
||||
backstory: "You have spent a decade creating content for leading technology companies, specializing in translating technical concepts for business audiences. You excel at research, interviewing subject matter experts, and structuring information for maximum clarity and impact. You believe that the best B2B content educates first and sells second, building trust through genuine expertise rather than marketing hype."
|
||||
```
|
||||
|
||||
### Example 2: Research Agent
|
||||
|
||||
**Before:**
|
||||
```yaml
|
||||
role: "Researcher"
|
||||
goal: "Find information"
|
||||
backstory: "You are good at finding information online."
|
||||
```
|
||||
|
||||
**After:**
|
||||
```yaml
|
||||
role: "Academic Research Specialist in Emerging Technologies"
|
||||
goal: "Discover and synthesize cutting-edge research, identifying key trends, methodologies, and findings while evaluating the quality and reliability of sources"
|
||||
backstory: "With a background in both computer science and library science, you've mastered the art of digital research. You've worked with research teams at prestigious universities and know how to navigate academic databases, evaluate research quality, and synthesize findings across disciplines. You're methodical in your approach, always cross-referencing information and tracing claims to primary sources before drawing conclusions."
|
||||
```
|
||||
|
||||
## Crafting Effective Tasks for Your Agents
|
||||
|
||||
While agent design is important, task design is critical for successful execution. Here are best practices for designing tasks that set your agents up for success:
|
||||
|
||||
### The Anatomy of an Effective Task
|
||||
|
||||
A well-designed task has two key components that serve different purposes:
|
||||
|
||||
#### Task Description: The Process
|
||||
The description should focus on what to do and how to do it, including:
|
||||
- Detailed instructions for execution
|
||||
- Context and background information
|
||||
- Scope and constraints
|
||||
- Process steps to follow
|
||||
|
||||
#### Expected Output: The Deliverable
|
||||
The expected output should define what the final result should look like:
|
||||
- Format specifications (markdown, JSON, etc.)
|
||||
- Structure requirements
|
||||
- Quality criteria
|
||||
- Examples of good outputs (when possible)
|
||||
|
||||
### Task Design Best Practices
|
||||
|
||||
#### 1. Single Purpose, Single Output
|
||||
Tasks perform best when focused on one clear objective:
|
||||
|
||||
**Bad Example (Too Broad):**
|
||||
```yaml
|
||||
task_description: "Research market trends, analyze the data, and create a visualization."
|
||||
```
|
||||
|
||||
**Good Example (Focused):**
|
||||
```yaml
|
||||
# Task 1
|
||||
research_task:
|
||||
description: "Research the top 5 market trends in the AI industry for 2024."
|
||||
expected_output: "A markdown list of the 5 trends with supporting evidence."
|
||||
|
||||
# Task 2
|
||||
analysis_task:
|
||||
description: "Analyze the identified trends to determine potential business impacts."
|
||||
expected_output: "A structured analysis with impact ratings (High/Medium/Low)."
|
||||
|
||||
# Task 3
|
||||
visualization_task:
|
||||
description: "Create a visual representation of the analyzed trends."
|
||||
expected_output: "A description of a chart showing trends and their impact ratings."
|
||||
```
|
||||
|
||||
#### 2. Be Explicit About Inputs and Outputs
|
||||
Always clearly specify what inputs the task will use and what the output should look like:
|
||||
|
||||
**Example:**
|
||||
```yaml
|
||||
analysis_task:
|
||||
description: >
|
||||
Analyze the customer feedback data from the CSV file.
|
||||
Focus on identifying recurring themes related to product usability.
|
||||
Consider sentiment and frequency when determining importance.
|
||||
expected_output: >
|
||||
A markdown report with the following sections:
|
||||
1. Executive summary (3-5 bullet points)
|
||||
2. Top 3 usability issues with supporting data
|
||||
3. Recommendations for improvement
|
||||
```
|
||||
|
||||
#### 3. Include Purpose and Context
|
||||
Explain why the task matters and how it fits into the larger workflow:
|
||||
|
||||
**Example:**
|
||||
```yaml
|
||||
competitor_analysis_task:
|
||||
description: >
|
||||
Analyze our three main competitors' pricing strategies.
|
||||
This analysis will inform our upcoming pricing model revision.
|
||||
Focus on identifying patterns in how they price premium features
|
||||
and how they structure their tiered offerings.
|
||||
```
|
||||
|
||||
#### 4. Use Structured Output Tools
|
||||
For machine-readable outputs, specify the format clearly:
|
||||
|
||||
**Example:**
|
||||
```yaml
|
||||
data_extraction_task:
|
||||
description: "Extract key metrics from the quarterly report."
|
||||
expected_output: "JSON object with the following keys: revenue, growth_rate, customer_acquisition_cost, and retention_rate."
|
||||
```
|
||||
|
||||
## Common Mistakes to Avoid
|
||||
|
||||
Based on lessons learned from real-world implementations, here are the most common pitfalls in agent and task design:
|
||||
|
||||
### 1. Unclear Task Instructions
|
||||
|
||||
**Problem:** Tasks lack sufficient detail, making it difficult for agents to execute effectively.
|
||||
|
||||
**Example of Poor Design:**
|
||||
```yaml
|
||||
research_task:
|
||||
description: "Research AI trends."
|
||||
expected_output: "A report on AI trends."
|
||||
```
|
||||
|
||||
**Improved Version:**
|
||||
```yaml
|
||||
research_task:
|
||||
description: >
|
||||
Research the top emerging AI trends for 2024 with a focus on:
|
||||
1. Enterprise adoption patterns
|
||||
2. Technical breakthroughs in the past 6 months
|
||||
3. Regulatory developments affecting implementation
|
||||
|
||||
For each trend, identify key companies, technologies, and potential business impacts.
|
||||
expected_output: >
|
||||
A comprehensive markdown report with:
|
||||
- Executive summary (5 bullet points)
|
||||
- 5-7 major trends with supporting evidence
|
||||
- For each trend: definition, examples, and business implications
|
||||
- References to authoritative sources
|
||||
```
|
||||
|
||||
### 2. "God Tasks" That Try to Do Too Much
|
||||
|
||||
**Problem:** Tasks that combine multiple complex operations into one instruction set.
|
||||
|
||||
**Example of Poor Design:**
|
||||
```yaml
|
||||
comprehensive_task:
|
||||
description: "Research market trends, analyze competitor strategies, create a marketing plan, and design a launch timeline."
|
||||
```
|
||||
|
||||
**Improved Version:**
|
||||
Break this into sequential, focused tasks:
|
||||
```yaml
|
||||
# Task 1: Research
|
||||
market_research_task:
|
||||
description: "Research current market trends in the SaaS project management space."
|
||||
expected_output: "A markdown summary of key market trends."
|
||||
|
||||
# Task 2: Competitive Analysis
|
||||
competitor_analysis_task:
|
||||
description: "Analyze strategies of the top 3 competitors based on the market research."
|
||||
expected_output: "A comparison table of competitor strategies."
|
||||
context: [market_research_task]
|
||||
|
||||
# Continue with additional focused tasks...
|
||||
```
|
||||
|
||||
### 3. Misaligned Description and Expected Output
|
||||
|
||||
**Problem:** The task description asks for one thing while the expected output specifies something different.
|
||||
|
||||
**Example of Poor Design:**
|
||||
```yaml
|
||||
analysis_task:
|
||||
description: "Analyze customer feedback to find areas of improvement."
|
||||
expected_output: "A marketing plan for the next quarter."
|
||||
```
|
||||
|
||||
**Improved Version:**
|
||||
```yaml
|
||||
analysis_task:
|
||||
description: "Analyze customer feedback to identify the top 3 areas for product improvement."
|
||||
expected_output: "A report listing the 3 priority improvement areas with supporting customer quotes and data points."
|
||||
```
|
||||
|
||||
### 4. Not Understanding the Process Yourself
|
||||
|
||||
**Problem:** Asking agents to execute tasks that you yourself don't fully understand.
|
||||
|
||||
**Solution:**
|
||||
1. Try to perform the task manually first
|
||||
2. Document your process, decision points, and information sources
|
||||
3. Use this documentation as the basis for your task description
|
||||
|
||||
### 5. Premature Use of Hierarchical Structures
|
||||
|
||||
**Problem:** Creating unnecessarily complex agent hierarchies where sequential processes would work better.
|
||||
|
||||
**Solution:** Start with sequential processes and only move to hierarchical models when the workflow complexity truly requires it.
|
||||
|
||||
### 6. Vague or Generic Agent Definitions
|
||||
|
||||
**Problem:** Generic agent definitions lead to generic outputs.
|
||||
|
||||
**Example of Poor Design:**
|
||||
```yaml
|
||||
agent:
|
||||
role: "Business Analyst"
|
||||
goal: "Analyze business data"
|
||||
backstory: "You are good at business analysis."
|
||||
```
|
||||
|
||||
**Improved Version:**
|
||||
```yaml
|
||||
agent:
|
||||
role: "SaaS Metrics Specialist focusing on growth-stage startups"
|
||||
goal: "Identify actionable insights from business data that can directly impact customer retention and revenue growth"
|
||||
backstory: "With 10+ years analyzing SaaS business models, you've developed a keen eye for the metrics that truly matter for sustainable growth. You've helped numerous companies identify the leverage points that turned around their business trajectory. You believe in connecting data to specific, actionable recommendations rather than general observations."
|
||||
```
|
||||
|
||||
## Advanced Agent Design Strategies
|
||||
|
||||
### Designing for Collaboration
|
||||
|
||||
When creating agents that will work together in a crew, consider:
|
||||
|
||||
- **Complementary skills**: Design agents with distinct but complementary abilities
|
||||
- **Handoff points**: Define clear interfaces for how work passes between agents
|
||||
- **Constructive tension**: Sometimes, creating agents with slightly different perspectives can lead to better outcomes through productive dialogue
|
||||
|
||||
For example, a content creation crew might include:
|
||||
|
||||
```yaml
|
||||
# Research Agent
|
||||
role: "Research Specialist for technical topics"
|
||||
goal: "Gather comprehensive, accurate information from authoritative sources"
|
||||
backstory: "You are a meticulous researcher with a background in library science..."
|
||||
|
||||
# Writer Agent
|
||||
role: "Technical Content Writer"
|
||||
goal: "Transform research into engaging, clear content that educates and informs"
|
||||
backstory: "You are an experienced writer who excels at explaining complex concepts..."
|
||||
|
||||
# Editor Agent
|
||||
role: "Content Quality Editor"
|
||||
goal: "Ensure content is accurate, well-structured, and polished while maintaining consistency"
|
||||
backstory: "With years of experience in publishing, you have a keen eye for detail..."
|
||||
```
|
||||
|
||||
### Creating Specialized Tool Users
|
||||
|
||||
Some agents can be designed specifically to leverage certain tools effectively:
|
||||
|
||||
```yaml
|
||||
role: "Data Analysis Specialist"
|
||||
goal: "Derive meaningful insights from complex datasets through statistical analysis"
|
||||
backstory: "With a background in data science, you excel at working with structured and unstructured data..."
|
||||
tools: [PythonREPLTool, DataVisualizationTool, CSVAnalysisTool]
|
||||
```
|
||||
|
||||
### Tailoring Agents to LLM Capabilities
|
||||
|
||||
Different LLMs have different strengths. Design your agents with these capabilities in mind:
|
||||
|
||||
```yaml
|
||||
# For complex reasoning tasks
|
||||
analyst:
|
||||
role: "Data Insights Analyst"
|
||||
goal: "..."
|
||||
backstory: "..."
|
||||
llm: openai/gpt-4o
|
||||
|
||||
# For creative content
|
||||
writer:
|
||||
role: "Creative Content Writer"
|
||||
goal: "..."
|
||||
backstory: "..."
|
||||
llm: anthropic/claude-3-opus
|
||||
```
|
||||
|
||||
## Testing and Iterating on Agent Design
|
||||
|
||||
Agent design is often an iterative process. Here's a practical approach:
|
||||
|
||||
1. **Start with a prototype**: Create an initial agent definition
|
||||
2. **Test with sample tasks**: Evaluate performance on representative tasks
|
||||
3. **Analyze outputs**: Identify strengths and weaknesses
|
||||
4. **Refine the definition**: Adjust role, goal, and backstory based on observations
|
||||
5. **Test in collaboration**: Evaluate how the agent performs in a crew setting
|
||||
|
||||
## Conclusion
|
||||
|
||||
Crafting effective agents is both an art and a science. By carefully defining roles, goals, and backstories that align with your specific needs, and combining them with well-designed tasks, you can create specialized AI collaborators that produce exceptional results.
|
||||
|
||||
Remember that agent and task design is an iterative process. Start with these best practices, observe your agents in action, and refine your approach based on what you learn. And always keep in mind the 80/20 rule - focus most of your effort on creating clear, focused tasks to get the best results from your agents.

## Choosing Between Crews and Flows
|
||||
|
||||
### When to Choose Crews
|
||||
|
||||
Crews are ideal when:
|
||||
|
||||
1. **You need collaborative intelligence** - Multiple agents with different specializations need to work together
|
||||
2. **The problem requires emergent thinking** - The solution benefits from different perspectives and approaches
|
||||
3. **The task is primarily creative or analytical** - The work involves research, content creation, or analysis
|
||||
4. **You value adaptability over strict structure** - The workflow can benefit from agent autonomy
|
||||
5. **The output format can be somewhat flexible** - Some variation in output structure is acceptable
|
||||
|
||||
```python
|
||||
# Example: Research Crew for market analysis
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
|
||||
# Create specialized agents
|
||||
researcher = Agent(
|
||||
role="Market Research Specialist",
|
||||
goal="Find comprehensive market data on emerging technologies",
|
||||
backstory="You are an expert at discovering market trends and gathering data."
|
||||
)
|
||||
|
||||
analyst = Agent(
|
||||
role="Market Analyst",
|
||||
goal="Analyze market data and identify key opportunities",
|
||||
backstory="You excel at interpreting market data and spotting valuable insights."
|
||||
)
|
||||
|
||||
# Define their tasks
|
||||
research_task = Task(
|
||||
description="Research the current market landscape for AI-powered healthcare solutions",
|
||||
expected_output="Comprehensive market data including key players, market size, and growth trends",
|
||||
agent=researcher
|
||||
)
|
||||
|
||||
analysis_task = Task(
|
||||
description="Analyze the market data and identify the top 3 investment opportunities",
|
||||
expected_output="Analysis report with 3 recommended investment opportunities and rationale",
|
||||
agent=analyst,
|
||||
context=[research_task]
|
||||
)
|
||||
|
||||
# Create the crew
|
||||
market_analysis_crew = Crew(
|
||||
agents=[researcher, analyst],
|
||||
tasks=[research_task, analysis_task],
|
||||
process=Process.sequential,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Run the crew
|
||||
result = market_analysis_crew.kickoff()
|
||||
```
|
||||
|
||||
### When to Choose Flows
|
||||
|
||||
Flows are ideal when:
|
||||
|
||||
1. **You need precise control over execution** - The workflow requires exact sequencing and state management
|
||||
2. **The application has complex state requirements** - You need to maintain and transform state across multiple steps
|
||||
3. **You need structured, predictable outputs** - The application requires consistent, formatted results
|
||||
4. **The workflow involves conditional logic** - Different paths need to be taken based on intermediate results
|
||||
5. **You need to combine AI with procedural code** - The solution requires both AI capabilities and traditional programming
|
||||
|
||||
```python
|
||||
# Example: Customer Support Flow with structured processing
|
||||
from crewai.flow.flow import Flow, listen, router, start
|
||||
from pydantic import BaseModel
|

# Run the flow
|
||||
support_flow = CustomerSupportFlow()
|
||||
result = support_flow.kickoff()
|
||||
```
|
||||
|
||||
### When to Combine Crews and Flows
|
||||
|
||||
The most sophisticated applications often benefit from combining Crews and Flows:
|
||||
|
||||
1. **Complex multi-stage processes** - Use Flows to orchestrate the overall process and Crews for complex subtasks
|
||||
2. **Applications requiring both creativity and structure** - Use Crews for creative tasks and Flows for structured processing
|
||||
3. **Enterprise-grade AI applications** - Use Flows to manage state and process flow while leveraging Crews for specialized work
|
||||
|
||||
```python
|

## Practical Evaluation Framework
|
||||
|
||||
To determine the right approach for your specific use case, follow this step-by-step evaluation framework:
|
||||
|
||||
### Step 1: Assess Complexity
|
||||
|
||||
Rate your application's complexity on a scale of 1-10 by considering:
|
||||
|
||||
1. **Number of steps**: How many distinct operations are required?
|
||||
- 1-3 steps: Low complexity (1-3)
|
||||
- 4-7 steps: Medium complexity (4-7)
|
||||
- 8+ steps: High complexity (8-10)
|
||||
|
||||
2. **Interdependencies**: How interconnected are the different parts?
|
||||
- Few dependencies: Low complexity (1-3)
|
||||
- Some dependencies: Medium complexity (4-7)
|
||||
- Many complex dependencies: High complexity (8-10)
|
||||
|
||||
3. **Conditional logic**: How much branching and decision-making is needed?
|
||||
- Linear process: Low complexity (1-3)
|
||||
- Some branching: Medium complexity (4-7)
|
||||
- Complex decision trees: High complexity (8-10)
|
||||
|
||||
4. **Domain knowledge**: How specialized is the knowledge required?
|
||||
- General knowledge: Low complexity (1-3)
|
||||
- Some specialized knowledge: Medium complexity (4-7)
|
||||
- Deep expertise in multiple domains: High complexity (8-10)
|
||||
|
||||
Calculate your average score to determine overall complexity.
|
||||
|
||||
### Step 2: Assess Precision Requirements
|
||||
|
||||
Rate your precision requirements on a scale of 1-10 by considering:
|
||||
|
||||
1. **Output structure**: How structured must the output be?
|
||||
- Free-form text: Low precision (1-3)
|
||||
- Semi-structured: Medium precision (4-7)
|
||||
- Strictly formatted (JSON, XML): High precision (8-10)
|
||||
|
||||
2. **Accuracy needs**: How important is factual accuracy?
|
||||
- Creative content: Low precision (1-3)
|
||||
- Informational content: Medium precision (4-7)
|
||||
- Critical information: High precision (8-10)
|
||||
|
||||
3. **Reproducibility**: How consistent must results be across runs?
|
||||
- Variation acceptable: Low precision (1-3)
|
||||
- Some consistency needed: Medium precision (4-7)
|
||||
- Exact reproducibility required: High precision (8-10)
|
||||
|
||||
4. **Error tolerance**: What is the impact of errors?
|
||||
- Low impact: Low precision (1-3)
|
||||
- Moderate impact: Medium precision (4-7)
|
||||
- High impact: High precision (8-10)
|
||||
|
||||
Calculate your average score to determine overall precision requirements.
|
||||
|
||||
### Step 3: Map to the Matrix
|
||||
|
||||
Plot your complexity and precision scores on the matrix:
|
||||
|
||||
- **Low Complexity (1-4), Low Precision (1-4)**: Simple Crews
|
||||
- **Low Complexity (1-4), High Precision (5-10)**: Flows with direct LLM calls
|
||||
- **High Complexity (5-10), Low Precision (1-4)**: Complex Crews
|
||||
- **High Complexity (5-10), High Precision (5-10)**: Flows orchestrating Crews
|
||||
|
||||
### Step 4: Consider Additional Factors
|
||||
|
||||
Beyond complexity and precision, consider:
|
||||
|
||||
1. **Development time**: Crews are often faster to prototype
|
||||
2. **Maintenance needs**: Flows provide better long-term maintainability
|
||||
3. **Team expertise**: Consider your team's familiarity with different approaches
|
||||
4. **Scalability requirements**: Flows typically scale better for complex applications
|
||||
5. **Integration needs**: Consider how the solution will integrate with existing systems
|
||||
|
||||
## Conclusion
|
||||
|
||||
Choosing between Crews and Flows—or combining them—is a critical architectural decision that impacts the effectiveness, maintainability, and scalability of your CrewAI application. By evaluating your use case along the dimensions of complexity and precision, you can make informed decisions that align with your specific requirements.
|
||||
|
||||
Remember that the best approach often evolves as your application matures. Start with the simplest solution that meets your needs, and be prepared to refine your architecture as you gain experience and your requirements become clearer.

## Unleashing the Power of Collaborative AI
|
||||
|
||||
Imagine having a team of specialized AI agents working together seamlessly to solve complex problems, each contributing their unique skills to achieve a common goal. This is the power of CrewAI - a framework that enables you to create collaborative AI systems that can accomplish tasks far beyond what a single AI could achieve alone.
|
||||
|
||||
In this guide, we'll walk through creating a research crew that will help us research and analyze a topic, then create a comprehensive report. This practical example demonstrates how AI agents can collaborate to accomplish complex tasks, but it's just the beginning of what's possible with CrewAI.

Before starting, make sure you have:
|
||||
|
||||
1. Installed CrewAI following the [installation guide](/installation)
|
||||
2. Set up your LLM API key in your environment, following the [LLM setup
|
||||
guide](/concepts/llms#setting-up-your-llm)
|
||||
3. Basic understanding of Python
|
||||
|
||||
## Step 1: Create a New CrewAI Project
|
||||
|
||||
First, let's create a new CrewAI project using the CLI. This command will set up a complete project structure with all the necessary files, allowing you to focus on defining your agents and their tasks rather than setting up boilerplate code.
|
||||
|
||||
```bash
|
||||
crewai create crew research_crew
|
||||
cd research_crew
|
||||
```
|
||||
|
||||
This will generate a project with the basic structure needed for your crew. The CLI automatically creates:
|
||||
|
||||
- A project directory with the necessary files
|
||||
- Configuration files for agents and tasks
|
||||
- A basic crew implementation
|
||||
- A main script to run the crew
|
||||
|
||||

|
||||
<img src="../../images/crews.png" alt="CrewAI Framework Overview" />
|
||||
</Frame>
|
||||
|
||||
|
||||
## Step 2: Explore the Project Structure
|
||||
|
||||
Let's take a moment to understand the project structure created by the CLI. CrewAI follows best practices for Python projects, making it easy to maintain and extend your code as your crews become more complex.
|
||||
|
||||
```
|
||||
research_crew/
|
||||
├── .gitignore
|
||||
├── pyproject.toml
|
||||
├── README.md
|
||||
├── .env
|
||||
└── src/
|
||||
└── research_crew/
|
||||
├── __init__.py
|
||||
├── main.py
|
||||
├── crew.py
|
||||
├── tools/
|
||||
│ ├── custom_tool.py
|
||||
│ └── __init__.py
|
||||
└── config/
|
||||
├── agents.yaml
|
||||
└── tasks.yaml
|
||||
```
|
||||
|
||||
This structure follows best practices for Python projects and makes it easy to organize your code. The separation of configuration files (in YAML) from implementation code (in Python) makes it easy to modify your crew's behavior without changing the underlying code.
|
||||
|
||||
## Step 3: Configure Your Agents
|
||||
|
||||
Now comes the fun part - defining your AI agents! In CrewAI, agents are specialized entities with specific roles, goals, and backstories that shape their behavior. Think of them as characters in a play, each with their own personality and purpose.
|
||||
|
||||
For our research crew, we'll create two agents:
|
||||
1. A **researcher** who excels at finding and organizing information
|
||||
2. An **analyst** who can interpret research findings and create insightful reports
|
||||
|
||||
Let's modify the `agents.yaml` file to define these specialized agents. Be sure
|
||||
to set `llm` to the provider you are using.
|
||||
|
||||
```yaml
|
||||
# src/research_crew/config/agents.yaml
|
||||
researcher:
|
||||
role: >
|
||||
Senior Research Specialist for {topic}
|
||||
goal: >
|
||||
Find comprehensive and accurate information about {topic}
|
||||
with a focus on recent developments and key insights
|
||||
backstory: >
|
||||
You are an experienced research specialist with a talent for
|
||||
finding relevant information from various sources. You excel at
|
||||
organizing information in a clear and structured manner, making
|
||||
complex topics accessible to others.
|
||||
llm: provider/model-id # e.g. openai/gpt-4o, google/gemini-2.0-flash, anthropic/claude...
|
||||
|
||||
analyst:
|
||||
role: >
|
||||
Data Analyst and Report Writer for {topic}
|
||||
goal: >
|
||||
Analyze research findings and create a comprehensive, well-structured
|
||||
report that presents insights in a clear and engaging way
|
||||
backstory: >
|
||||
You are a skilled analyst with a background in data interpretation
|
||||
and technical writing. You have a talent for identifying patterns
|
||||
and extracting meaningful insights from research data, then
|
||||
communicating those insights effectively through well-crafted reports.
|
||||
llm: provider/model-id # e.g. openai/gpt-4o, google/gemini-2.0-flash, anthropic/claude...
|
||||
```
|
||||
|
||||
Notice how each agent has a distinct role, goal, and backstory. These elements aren't just descriptive - they actively shape how the agent approaches its tasks. By crafting these carefully, you can create agents with specialized skills and perspectives that complement each other.
|
||||
|
||||
## Step 4: Define Your Tasks
|
||||
|
||||
With our agents defined, we now need to give them specific tasks to perform. Tasks in CrewAI represent the concrete work that agents will perform, with detailed instructions and expected outputs.
|
||||
|
||||
For our research crew, we'll define two main tasks:
|
||||
1. A **research task** for gathering comprehensive information
|
||||
2. An **analysis task** for creating an insightful report
|
||||
|
||||
Let's modify the `tasks.yaml` file:
|
||||
|
||||
```yaml
|
||||
# src/research_crew/config/tasks.yaml
|
||||
research_task:
|
||||
description: >
|
||||
Conduct thorough research on {topic}. Focus on:
|
||||
1. Key concepts and definitions
|
||||
2. Historical development and recent trends
|
||||
3. Major challenges and opportunities
|
||||
4. Notable applications or case studies
|
||||
5. Future outlook and potential developments
|
||||
|
||||
Make sure to organize your findings in a structured format with clear sections.
|
||||
expected_output: >
|
||||
A comprehensive research document with well-organized sections covering
|
||||
all the requested aspects of {topic}. Include specific facts, figures,
|
||||
and examples where relevant.
|
||||
agent: researcher
|
||||
|
||||
analysis_task:
|
||||
description: >
|
||||
Analyze the research findings and create a comprehensive report on {topic}.
|
||||
Your report should:
|
||||
1. Begin with an executive summary
|
||||
2. Include all key information from the research
|
||||
3. Provide insightful analysis of trends and patterns
|
||||
4. Offer recommendations or future considerations
|
||||
5. Be formatted in a professional, easy-to-read style with clear headings
|
||||
expected_output: >
|
||||
A polished, professional report on {topic} that presents the research
|
||||
findings with added analysis and insights. The report should be well-structured
|
||||
with an executive summary, main sections, and conclusion.
|
||||
agent: analyst
|
||||
context:
|
||||
- research_task
|
||||
output_file: output/report.md
|
||||
```
|
||||
|
||||
Note the `context` field in the analysis task - this is a powerful feature that allows the analyst to access the output of the research task. This creates a workflow where information flows naturally between agents, just as it would in a human team.
|
||||
|
||||
## Step 5: Configure Your Crew
|
||||
|
||||
Now it's time to bring everything together by configuring our crew. The crew is the container that orchestrates how agents work together to complete tasks.
|
||||
|
||||
Let's modify the `crew.py` file:
|
||||
|
||||
```python
|
||||
# src/research_crew/crew.py
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from crewai.project import CrewBase, agent, crew, task
|
||||
from crewai_tools import SerperDevTool
|
||||
from crewai.agents.agent_builder.base_agent import BaseAgent
|
||||
from typing import List
|
||||
|
||||
@CrewBase
|
||||
class ResearchCrew():
|
||||
"""Research crew for comprehensive topic analysis and reporting"""
|
||||
|
||||
agents: List[BaseAgent]
|
||||
tasks: List[Task]
|
||||
|
||||
@agent
|
||||
def researcher(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['researcher'], # type: ignore[index]
|
||||
verbose=True,
|
||||
tools=[SerperDevTool()]
|
||||
)
|
||||
|
||||
@agent
|
||||
def analyst(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['analyst'], # type: ignore[index]
|
||||
verbose=True
|
||||
)
|
||||
|
||||
@task
|
||||
def research_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['research_task'] # type: ignore[index]
|
||||
)
|
||||
|
||||
@task
|
||||
def analysis_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['analysis_task'], # type: ignore[index]
|
||||
output_file='output/report.md'
|
||||
)
|
||||
|
||||
@crew
|
||||
def crew(self) -> Crew:
|
||||
"""Creates the research crew"""
|
||||
return Crew(
|
||||
agents=self.agents,
|
||||
tasks=self.tasks,
|
||||
process=Process.sequential,
|
||||
verbose=True,
|
||||
)
|
||||
```
|
||||
|
||||
In this code, we're:
|
||||
1. Creating the researcher agent and equipping it with the SerperDevTool to search the web
|
||||
2. Creating the analyst agent
|
||||
3. Setting up the research and analysis tasks
|
||||
4. Configuring the crew to run tasks sequentially (the analyst will wait for the researcher to finish)
|
||||
|
||||
This is where the magic happens - with just a few lines of code, we've defined a collaborative AI system where specialized agents work together in a coordinated process.
|
||||
|
||||
## Step 6: Set Up Your Main Script
|
||||
|
||||
Now, let's set up the main script that will run our crew. This is where we provide the specific topic we want our crew to research.
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python
|
||||
# src/research_crew/main.py
|
||||
import os
|
||||
from research_crew.crew import ResearchCrew
|
||||
|
||||
# Create output directory if it doesn't exist
|
||||
os.makedirs('output', exist_ok=True)
|
||||
|
||||
def run():
|
||||
"""
|
||||
Run the research crew.
|
||||
"""
|
||||
inputs = {
|
||||
'topic': 'Artificial Intelligence in Healthcare'
|
||||
}
|
||||
|
||||
# Create and run the crew
|
||||
result = ResearchCrew().crew().kickoff(inputs=inputs)
|
||||
|
||||
# Print the result
|
||||
print("\n\n=== FINAL REPORT ===\n\n")
|
||||
print(result.raw)
|
||||
|
||||
print("\n\nReport has been saved to output/report.md")
|
||||
|
||||
if __name__ == "__main__":
|
||||
run()
|
||||
```
|
||||
|
||||
This script prepares the environment, specifies our research topic, and kicks off the crew's work. The power of CrewAI is evident in how simple this code is - all the complexity of managing multiple AI agents is handled by the framework.
|
||||
|
||||
## Step 7: Set Up Your Environment Variables
|
||||
|
||||
Create a `.env` file in your project root with your API keys:
|
||||
|
||||
```sh
|
||||
SERPER_API_KEY=your_serper_api_key
|
||||
# Add your provider's API key here too.
|
||||
```
|
||||
|
||||
See the [LLM Setup guide](/concepts/llms#setting-up-your-llm) for details on configuring your provider of choice. You can get a Serper API key from [Serper.dev](https://serper.dev/).
|
||||
|
||||
## Step 8: Install Dependencies
|
||||
|
||||
Install the required dependencies using the CrewAI CLI:
|
||||
|
||||
```bash
|
||||
crewai install
|
||||
```
|
||||
|
||||
This command will:
|
||||
1. Read the dependencies from your project configuration
|
||||
2. Create a virtual environment if needed
|
||||
3. Install all required packages
|
||||
|
||||
## Step 9: Run Your Crew
|
||||
|
||||
Now for the exciting moment - it's time to run your crew and see AI collaboration in action!
|
||||
|
||||
```bash
|
||||
crewai run
|
||||
```
|
||||
|
||||
When you run this command, you'll see your crew spring to life. The researcher will gather information about the specified topic, and the analyst will then create a comprehensive report based on that research. You'll see the agents' thought processes, actions, and outputs in real-time as they work together to complete their tasks.
|
||||
|
||||
## Step 10: Review the Output
|
||||
|
||||
Once the crew completes its work, you'll find the final report in the `output/report.md` file. The report will include:
|
||||
|
||||
1. An executive summary
|
||||
2. Detailed information about the topic
|
||||
3. Analysis and insights
|
||||
4. Recommendations or future considerations
|
||||
|
||||
Take a moment to appreciate what you've accomplished - you've created a system where multiple AI agents collaborated on a complex task, each contributing their specialized skills to produce a result that's greater than what any single agent could achieve alone.
|
||||
|
||||
## Exploring Other CLI Commands
|
||||
|
||||
CrewAI offers several other useful CLI commands for working with crews:
|
||||
|
||||
```bash
|
||||
# View all available commands
|
||||
crewai --help
|
||||
|
||||
# Run the crew
|
||||
crewai run
|
||||
|
||||
# Test the crew
|
||||
crewai test
|
||||
|
||||
# Reset crew memories
|
||||
crewai reset-memories
|
||||
|
||||
# Replay from a specific task
|
||||
crewai replay -t <task_id>
|
||||
```
|
||||
|
||||
## The Art of the Possible: Beyond Your First Crew
|
||||
|
||||
What you've built in this guide is just the beginning. The skills and patterns you've learned can be applied to create increasingly sophisticated AI systems. Here are some ways you could extend this basic research crew:
|
||||
|
||||
### Expanding Your Crew
|
||||
|
||||
You could add more specialized agents to your crew:
|
||||
- A **fact-checker** to verify research findings
|
||||
- A **data visualizer** to create charts and graphs
|
||||
- A **domain expert** with specialized knowledge in a particular area
|
||||
- A **critic** to identify weaknesses in the analysis
|
||||
|
||||
### Adding Tools and Capabilities
|
||||
|
||||
You could enhance your agents with additional tools:
|
||||
- Web browsing tools for real-time research
|
||||
- CSV/database tools for data analysis
|
||||
- Code execution tools for data processing
|
||||
- API connections to external services
|
||||
|
||||
### Creating More Complex Workflows
|
||||
|
||||
You could implement more sophisticated processes:
|
||||
- Hierarchical processes where manager agents delegate to worker agents
|
||||
- Iterative processes with feedback loops for refinement
|
||||
- Parallel processes where multiple agents work simultaneously
|
||||
- Dynamic processes that adapt based on intermediate results
|
||||
|
||||

## Taking Control of AI Workflows with Flows
|
||||
|
||||
CrewAI Flows represent the next level in AI orchestration - combining the collaborative power of AI agent crews with the precision and flexibility of procedural programming. While crews excel at agent collaboration, flows give you fine-grained control over exactly how and when different components of your AI system interact.
|
||||
|
||||
In this guide, we'll walk through creating a powerful CrewAI Flow that generates a comprehensive learning guide on any topic. This tutorial will demonstrate how Flows provide structured, event-driven control over your AI workflows by combining regular code, direct LLM calls, and crew-based processing.
|
||||
|
||||
### What Makes Flows Powerful
|
||||
|
||||
Flows enable you to:
|
||||
|
||||
1. **Combine different AI interaction patterns** - Use crews for complex collaborative tasks, direct LLM calls for simpler operations, and regular code for procedural logic
|
||||
2. **Build event-driven systems** - Define how components respond to specific events and data changes
|
||||
3. **Maintain state across components** - Share and transform data between different parts of your application
|
||||
4. **Integrate with external systems** - Seamlessly connect your AI workflow with databases, APIs, and user interfaces
|
||||
5. **Create complex execution paths** - Design conditional branches, parallel processing, and dynamic workflows
|
||||
|
||||
### What You'll Build and Learn
|
||||
|
||||
By the end of this guide, you'll have:
|
||||
|
||||
1. **Created a sophisticated content generation system** that combines user input, AI planning, and multi-agent content creation
|
||||
2. **Orchestrated the flow of information** between different components of your system
|
||||
3. **Implemented event-driven architecture** where each step responds to the completion of previous steps
|
||||
4. **Built a foundation for more complex AI applications** that you can expand and customize
|
||||
|
||||
This guide creator flow demonstrates fundamental patterns that can be applied to create much more advanced applications, such as:
|
||||
|
||||
- Interactive AI assistants that combine multiple specialized subsystems
|
||||
- Complex data processing pipelines with AI-enhanced transformations
|
||||
- Autonomous agents that integrate with external services and APIs
|
||||
- Multi-stage decision-making systems with human-in-the-loop processes
|
||||
|
||||
Let's dive in and build your first flow!
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before starting, make sure you have:
|
||||
|
||||
1. Installed CrewAI following the [installation guide](/installation)
|
||||
2. Set up your LLM API key in your environment, following the [LLM setup
|
||||
guide](/concepts/llms#setting-up-your-llm)
|
||||
3. Basic understanding of Python
|
||||
|
||||
## Step 1: Create a New CrewAI Flow Project
|
||||
|
||||
First, let's create a new CrewAI Flow project using the CLI. This command sets up a scaffolded project with all the necessary directories and template files for your flow.
|
||||
|
||||
```bash
|
||||
crewai create flow guide_creator_flow
|
||||
cd guide_creator_flow
|
||||
```
|
||||
|
||||
This will generate a project with the basic structure needed for your flow.
|
||||
|
||||
<Frame caption="CrewAI Framework Overview">
|
||||
<img src="../../images/flows.png" alt="CrewAI Framework Overview" />
|
||||
</Frame>
|
||||
|
||||
## Step 2: Understanding the Project Structure
|
||||
|
||||
The generated project has the following structure. Take a moment to familiarize yourself with it, as understanding this structure will help you create more complex flows in the future.
|
||||
|
||||
```
|
||||
guide_creator_flow/
|
||||
├── .gitignore
|
||||
├── pyproject.toml
|
||||
├── README.md
|
||||
├── .env
|
||||
├── main.py
|
||||
├── crews/
|
||||
│ └── poem_crew/
|
||||
│ ├── config/
|
||||
│ │ ├── agents.yaml
|
||||
│ │ └── tasks.yaml
|
||||
│ └── poem_crew.py
|
||||
└── tools/
|
||||
└── custom_tool.py
|
||||
```
|
||||
|
||||
This structure provides a clear separation between different components of your flow:
|
||||
- The main flow logic in the `main.py` file
|
||||
- Specialized crews in the `crews` directory
|
||||
- Custom tools in the `tools` directory
|
||||
|
||||
We'll modify this structure to create our guide creator flow, which will orchestrate the process of generating comprehensive learning guides.
|
||||
|
||||
## Step 3: Add a Content Writer Crew
|
||||
|
||||
Our flow will need a specialized crew to handle the content creation process. Let's use the CrewAI CLI to add a content writer crew:
|
||||
|
||||
```bash
|
||||
crewai flow add-crew content-crew
|
||||
```
|
||||
|
||||
This command automatically creates the necessary directories and template files for your crew. The content writer crew will be responsible for writing and reviewing sections of our guide, working within the overall flow orchestrated by our main application.
|
||||
|
||||
## Step 4: Configure the Content Writer Crew
|
||||
|
||||
Now, let's modify the generated files for the content writer crew. We'll set up two specialized agents - a writer and a reviewer - that will collaborate to create high-quality content for our guide.
|
||||
|
||||
1. First, update the agents configuration file to define our content creation team:
|
||||
|
||||
Remember to set `llm` to the provider you are using.
|
||||
|
||||
```yaml
|
||||
# src/guide_creator_flow/crews/content_crew/config/agents.yaml
|
||||
content_writer:
|
||||
role: >
|
||||
Educational Content Writer
|
||||
goal: >
|
||||
Create engaging, informative content that thoroughly explains the assigned topic
|
||||
and provides valuable insights to the reader
|
||||
backstory: >
|
||||
You are a talented educational writer with expertise in creating clear, engaging
|
||||
content. You have a gift for explaining complex concepts in accessible language
|
||||
and organizing information in a way that helps readers build their understanding.
|
||||
llm: provider/model-id # e.g. openai/gpt-4o, google/gemini-2.0-flash, anthropic/claude...
|
||||
|
||||
content_reviewer:
|
||||
role: >
|
||||
Educational Content Reviewer and Editor
|
||||
goal: >
|
||||
Ensure content is accurate, comprehensive, well-structured, and maintains
|
||||
consistency with previously written sections
|
||||
backstory: >
|
||||
You are a meticulous editor with years of experience reviewing educational
|
||||
content. You have an eye for detail, clarity, and coherence. You excel at
|
||||
improving content while maintaining the original author's voice and ensuring
|
||||
consistent quality across multiple sections.
|
||||
llm: provider/model-id # e.g. openai/gpt-4o, google/gemini-2.0-flash, anthropic/claude...
|
||||
```
|
||||
|
||||
These agent definitions establish the specialized roles and perspectives that will shape how our AI agents approach content creation. Notice how each agent has a distinct purpose and expertise.
|
||||
|
||||
2. Next, update the tasks configuration file to define the specific writing and reviewing tasks:
|
||||
|
||||
```yaml
|
||||
# src/guide_creator_flow/crews/content_crew/config/tasks.yaml
|
||||
write_section_task:
|
||||
description: >
|
||||
Write a comprehensive section on the topic: "{section_title}"
|
||||
|
||||
Section description: {section_description}
|
||||
Target audience: {audience_level} level learners
|
||||
|
||||
Your content should:
|
||||
1. Begin with a brief introduction to the section topic
|
||||
2. Explain all key concepts clearly with examples
|
||||
3. Include practical applications or exercises where appropriate
|
||||
4. End with a summary of key points
|
||||
5. Be approximately 500-800 words in length
|
||||
|
||||
Format your content in Markdown with appropriate headings, lists, and emphasis.
|
||||
|
||||
Previously written sections:
|
||||
{previous_sections}
|
||||
|
||||
Make sure your content maintains consistency with previously written sections
|
||||
and builds upon concepts that have already been explained.
|
||||
expected_output: >
|
||||
A well-structured, comprehensive section in Markdown format that thoroughly
|
||||
explains the topic and is appropriate for the target audience.
|
||||
agent: content_writer
|
||||
|
||||
review_section_task:
|
||||
description: >
|
||||
Review and improve the following section on "{section_title}":
|
||||
|
||||
{draft_content}
|
||||
|
||||
Target audience: {audience_level} level learners
|
||||
|
||||
Previously written sections:
|
||||
{previous_sections}
|
||||
|
||||
Your review should:
|
||||
1. Fix any grammatical or spelling errors
|
||||
2. Improve clarity and readability
|
||||
3. Ensure content is comprehensive and accurate
|
||||
4. Verify consistency with previously written sections
|
||||
5. Enhance the structure and flow
|
||||
6. Add any missing key information
|
||||
|
||||
Provide the improved version of the section in Markdown format.
|
||||
expected_output: >
|
||||
An improved, polished version of the section that maintains the original
|
||||
structure but enhances clarity, accuracy, and consistency.
|
||||
agent: content_reviewer
|
||||
context:
|
||||
- write_section_task
|
||||
```
|
||||
|
||||
These task definitions provide detailed instructions to our agents, ensuring they produce content that meets our quality standards. Note how the `context` parameter in the review task creates a workflow where the reviewer has access to the writer's output.
|
||||
|
||||
3. Now, update the crew implementation file to define how our agents and tasks work together:
|
||||
|
||||
```python
|
||||
# src/guide_creator_flow/crews/content_crew/content_crew.py
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from crewai.project import CrewBase, agent, crew, task
|
||||
from crewai.agents.agent_builder.base_agent import BaseAgent
|
||||
from typing import List
|
||||
|
||||
@CrewBase
|
||||
class ContentCrew():
|
||||
"""Content writing crew"""
|
||||
|
||||
agents: List[BaseAgent]
|
||||
tasks: List[Task]
|
||||
|
||||
@agent
|
||||
def content_writer(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['content_writer'], # type: ignore[index]
|
||||
verbose=True
|
||||
)
|
||||
|
||||
@agent
|
||||
def content_reviewer(self) -> Agent:
|
||||
return Agent(
|
||||
config=self.agents_config['content_reviewer'], # type: ignore[index]
|
||||
verbose=True
|
||||
)
|
||||
|
||||
@task
|
||||
def write_section_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['write_section_task'] # type: ignore[index]
|
||||
)
|
||||
|
||||
@task
|
||||
def review_section_task(self) -> Task:
|
||||
return Task(
|
||||
config=self.tasks_config['review_section_task'], # type: ignore[index]
|
||||
context=[self.write_section_task()]
|
||||
)
|
||||
|
||||
@crew
|
||||
def crew(self) -> Crew:
|
||||
"""Creates the content writing crew"""
|
||||
return Crew(
|
||||
agents=self.agents,
|
||||
tasks=self.tasks,
|
||||
process=Process.sequential,
|
||||
verbose=True,
|
||||
)
|
||||
```
|
||||
|
||||
This crew definition establishes the relationship between our agents and tasks, setting up a sequential process where the content writer creates a draft and then the reviewer improves it. While this crew can function independently, in our flow it will be orchestrated as part of a larger system.
|
||||
|
||||
## Step 5: Create the Flow
|
||||
|
||||
Now comes the exciting part - creating the flow that will orchestrate the entire guide creation process. This is where we'll combine regular Python code, direct LLM calls, and our content creation crew into a cohesive system.
|
||||
|
||||
Our flow will:
|
||||
1. Get user input for a topic and audience level
|
||||
2. Make a direct LLM call to create a structured guide outline
|
||||
3. Process each section sequentially using the content writer crew
|
||||
4. Combine everything into a final comprehensive document
|
||||
|
||||
Let's create our flow in the `main.py` file:
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python
|
||||
import json
|
||||
import os
|
||||
from typing import List, Dict
|
||||
from pydantic import BaseModel, Field
|
||||
from crewai import LLM
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from guide_creator_flow.crews.content_crew.content_crew import ContentCrew
|
||||
|
||||
# Define our models for structured data
|
||||
class Section(BaseModel):
|
||||
title: str = Field(description="Title of the section")
|
||||
description: str = Field(description="Brief description of what the section should cover")
|
||||
|
||||
class GuideOutline(BaseModel):
|
||||
title: str = Field(description="Title of the guide")
|
||||
introduction: str = Field(description="Introduction to the topic")
|
||||
target_audience: str = Field(description="Description of the target audience")
|
||||
sections: List[Section] = Field(description="List of sections in the guide")
|
||||
conclusion: str = Field(description="Conclusion or summary of the guide")
|
||||
|
||||
# Define our flow state
|
||||

|
||||

|
||||

|
||||

|
||||
|
||||

|
||||
|

# Get audience level with validation
|
||||
while True:
|
||||
audience = input("Who is your target audience? (beginner/intermediate/advanced) ").lower()
|
||||
if audience in ["beginner", "intermediate", "advanced"]:
|
||||
self.state.audience_level = audience
|
||||
break
|
||||
print("Please enter 'beginner', 'intermediate', or 'advanced'")
|
||||
|
||||
print(f"\nCreating a guide on {self.state.topic} for {self.state.audience_level} audience...\n")
|
||||
return self.state
|
||||
|
||||
@listen(get_user_input)
|
||||
def create_guide_outline(self, state):

|
||||
print("Creating guide outline...")
|
||||

return "Guide creation completed successfully"

print("\n=== Flow Complete ===")

print("Open output/complete_guide.md to view it.")
|

|
||||
def plot():
|
||||
"""Generate a visualization of the flow"""
|
||||
flow = GuideCreatorFlow()
|
||||
flow.plot("guide_creator_flow")
|
||||
print("Flow visualization saved to guide_creator_flow.html")
|
||||
|
||||
if __name__ == "__main__":
|
||||
kickoff()
|
||||
```
|
||||
|
||||
Let's analyze what's happening in this flow:
|
||||
|
||||
1. We define Pydantic models for structured data, ensuring type safety and clear data representation
|
||||
2. We create a state class to maintain data across different steps of the flow
|
||||
3. We implement three main flow steps:
|
||||
- Getting user input with the `@start()` decorator
|
||||
- Creating a guide outline with a direct LLM call
|
||||
- Processing sections with our content crew
|
||||
4. We use the `@listen()` decorator to establish event-driven relationships between steps
|
||||
|
||||
This is the power of flows - combining different types of processing (user interaction, direct LLM calls, crew-based tasks) into a coherent, event-driven system.
|
||||
|
||||
## Step 6: Set Up Your Environment Variables
|
||||
|
||||
Create a `.env` file in your project root with your API keys. See the [LLM setup
|
||||
guide](/concepts/llms#setting-up-your-llm) for details on configuring a provider.
|
||||
|
||||
```sh .env
|
||||
OPENAI_API_KEY=your_openai_api_key
|
||||
# or
|
||||
GEMINI_API_KEY=your_gemini_api_key
|
||||
# or
|
||||
ANTHROPIC_API_KEY=your_anthropic_api_key
|
||||
```
|
||||
|
||||
## Step 7: Install Dependencies
|
||||
|
||||
Install the required dependencies:
|
||||
|
||||
```bash
|
||||
crewai install
|
||||
```
|
||||
|
||||
## Step 8: Run Your Flow
|
||||
|
||||
Now it's time to see your flow in action! Run it using the CrewAI CLI:
|
||||
|
||||
```bash
|
||||
crewai flow kickoff
|
||||
```
|
||||
|
||||
When you run this command, you'll see your flow spring to life:
|
||||
1. It will prompt you for a topic and audience level
|
||||
2. It will create a structured outline for your guide
|
||||
3. It will process each section, with the content writer and reviewer collaborating on each
|
||||
4. Finally, it will compile everything into a comprehensive guide
|
||||
|
||||
This demonstrates the power of flows to orchestrate complex processes involving multiple components, both AI and non-AI.
|
||||
|
||||
## Step 9: Visualize Your Flow
|
||||
|
||||
One of the powerful features of flows is the ability to visualize their structure:
|
||||
|
||||
```bash
|
||||
crewai flow plot
|
||||
```
|
||||
|
||||
This will create an HTML file that shows the structure of your flow, including the relationships between different steps and the data that flows between them. This visualization can be invaluable for understanding and debugging complex flows.
|
||||
|
||||
## Step 10: Review the Output
|
||||
|
||||
Once the flow completes, you'll find two files in the `output` directory:
|
||||
|
||||
1. `guide_outline.json`: Contains the structured outline of the guide
|
||||
2. `complete_guide.md`: The comprehensive guide with all sections
|
||||
|
||||
Take a moment to review these files and appreciate what you've built - a system that combines user input, direct AI interactions, and collaborative agent work to produce a complex, high-quality output.
|
||||
|
||||
## The Art of the Possible: Beyond Your First Flow
|
||||
|
||||
What you've learned in this guide provides a foundation for creating much more sophisticated AI systems. Here are some ways you could extend this basic flow:
|
||||
|
||||
### Enhancing User Interaction
|
||||
|
||||
You could create more interactive flows with:
|
||||
- Web interfaces for input and output
|
||||
- Real-time progress updates
|
||||
- Interactive feedback and refinement loops
|
||||
- Multi-stage user interactions
|
||||
|
||||
### Adding More Processing Steps
|
||||
|
||||
You could expand your flow with additional steps for:
|
||||
- Research before outline creation
|
||||
- Image generation for illustrations
|
||||
- Code snippet generation for technical guides
|
||||
- Final quality assurance and fact-checking
|
||||
|
||||
### Creating More Complex Flows
|
||||
|
||||
You could implement more sophisticated flow patterns:
|
||||
- Conditional branching based on user preferences or content type
|
||||
- Parallel processing of independent sections
|
||||
- Iterative refinement loops with feedback
|
||||
- Integration with external APIs and services
|
||||
|
||||
### Applying to Different Domains
|
||||
|
||||
The same patterns can be applied to create flows for:
|
||||
- **Interactive storytelling**: Create personalized stories based on user input
|
||||
- **Business intelligence**: Process data, generate insights, and create reports
|
||||
- **Product development**: Facilitate ideation, design, and planning
|
||||
- **Educational systems**: Create personalized learning experiences
|
||||
|
||||
## Key Features Demonstrated
|
||||
|
||||
This guide creator flow demonstrates several powerful features of CrewAI:
|
||||
|
||||
1. **User interaction**: The flow collects input directly from the user
|
||||
2. **Direct LLM calls**: Uses the LLM class for efficient, single-purpose AI interactions
|
||||
3. **Structured data with Pydantic**: Uses Pydantic models to ensure type safety
|
||||
4. **Sequential processing with context**: Writes sections in order, providing previous sections for context
|
||||
5. **Multi-agent crews**: Leverages specialized agents (writer and reviewer) for content creation
|
||||
6. **State management**: Maintains state across different steps of the process
|
||||
7. **Event-driven architecture**: Uses the `@listen` decorator to respond to events
|
||||
|
||||
## Understanding the Flow Structure
|
||||
|
||||
Let's break down the key components of flows to help you understand how to build your own:
|
||||
|
||||
### 1. Direct LLM Calls
|
||||
|
||||
Flows allow you to make direct calls to language models when you need simple, structured responses:
|
||||
|
||||
```python
|
||||
llm = LLM(
|
||||
model="model-id-here", # gpt-4o, gemini-2.0-flash, anthropic/claude...
|
||||
response_format=GuideOutline
|
||||
)
|
||||
response = llm.call(messages=messages)
|
||||
```
|
||||
|
||||
This is more efficient than using a crew when you need a specific, structured output.
|
||||
|
||||
### 2. Event-Driven Architecture
|
||||
|
||||
Flows use decorators to establish relationships between components:
|
||||
|
||||
```python
|
||||
@start()
|
||||
def get_user_input(self):
|
||||
# First step in the flow
|
||||
# ...
|
||||
|
||||
@listen(get_user_input)
|
||||
def create_guide_outline(self, state):
|
||||
# This runs when get_user_input completes
|
||||
# ...
|
||||
```
|
||||
|
||||
This creates a clear, declarative structure for your application.
|
||||
|
||||
### 3. State Management
|
||||
|
||||
Flows maintain state across steps, making it easy to share data:
|
||||
|
||||
```python
|
||||
class GuideCreatorState(BaseModel):
|
||||
topic: str = ""
|
||||
audience_level: str = ""
|
||||
guide_outline: GuideOutline = None
|
||||
sections_content: Dict[str, str] = {}
|
||||
```
|
||||
|
||||
This provides a type-safe way to track and transform data throughout your flow.
|
||||
|
||||
### 4. Crew Integration
|
||||
|
||||
Flows can seamlessly integrate with crews for complex collaborative tasks:
|
||||
|
||||
```python
|
||||
result = ContentCrew().crew().kickoff(inputs={
|
||||
"section_title": section.title,
|
||||
# ...
|
||||
})
|
||||
```
|
||||
|
||||
This allows you to use the right tool for each part of your application - direct LLM calls for simple tasks and crews for complex collaboration.
|
||||
|
||||
## Next Steps
|
||||
|
||||
Now that you've built your first flow, you can:
|
||||
|
||||
1. Experiment with more complex flow structures and patterns
|
||||
2. Try using `@router()` to create conditional branches in your flows
|
||||
3. Explore the `and_` and `or_` functions for more complex parallel execution
|
||||
4. Connect your flow to external APIs, databases, or user interfaces
|
||||
5. Combine multiple specialized crews in a single flow
|
||||
|
||||
<Check>
|
||||
Congratulations! You've successfully built your first CrewAI Flow that combines regular code, direct LLM calls, and crew-based processing to create a comprehensive guide. These foundational skills enable you to create increasingly sophisticated AI applications that can tackle complex, multi-stage problems through a combination of procedural control and collaborative intelligence.

||||
|
||||
State management is the backbone of any sophisticated AI workflow. In CrewAI Flows, the state system allows you to maintain context, share data between steps, and build complex application logic. Mastering state management is essential for creating reliable, maintainable, and powerful AI applications.
|
||||
|
||||
This guide will walk you through everything you need to know about managing state in CrewAI Flows, from basic concepts to advanced techniques, with practical code examples along the way.
|
||||
|
||||
### Why State Management Matters
|
||||
|
||||
Effective state management enables you to:
|
||||
|
||||
1. **Maintain context across execution steps** - Pass information seamlessly between different stages of your workflow
|
||||
2. **Build complex conditional logic** - Make decisions based on accumulated data
|
||||
3. **Create persistent applications** - Save and restore workflow progress
|
||||
4. **Handle errors gracefully** - Implement recovery patterns for more robust applications
|
||||
5. **Scale your applications** - Support complex workflows with proper data organization
|
||||
6. **Enable conversational applications** - Store and access conversation history for context-aware AI interactions
|
||||
|
||||
Let's explore how to leverage these capabilities effectively.
|
||||
|
||||
## State Management Fundamentals
|
||||
|
||||
### The Flow State Lifecycle
|
||||
|
||||
In CrewAI Flows, the state follows a predictable lifecycle:
|
||||
|
||||
1. **Initialization** - When a flow is created, its state is initialized (either as an empty dictionary or a Pydantic model instance)
|
||||
2. **Modification** - Flow methods access and modify the state as they execute
|
||||
3. **Transmission** - State is passed automatically between flow methods
|
||||
4. **Persistence** (optional) - State can be saved to storage and later retrieved
|
||||
5. **Completion** - The final state reflects the cumulative changes from all executed methods
|
||||
|
||||
Understanding this lifecycle is crucial for designing effective flows.
|
||||
|
||||
### Two Approaches to State Management
|
||||
|
||||
CrewAI offers two ways to manage state in your flows:
|
||||
|
||||
1. **Unstructured State** - Using dictionary-like objects for flexibility
|
||||
2. **Structured State** - Using Pydantic models for type safety and validation
|
||||
|
||||
Let's examine each approach in detail.
|
||||
|
||||
## Unstructured State Management
|
||||
|
||||
Unstructured state uses a dictionary-like approach, offering flexibility and simplicity for straightforward applications.
|
||||
|
||||
### How It Works
|
||||
|
||||
With unstructured state:
|
||||
- You access state via `self.state` which behaves like a dictionary
|
||||
- You can freely add, modify, or remove keys at any point
|
||||
- All state is automatically available to all flow methods
|
||||
|
||||
### Basic Example
|
||||
|
||||
Here's a simple example of unstructured state management:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
|
||||
class UnstructuredStateFlow(Flow):
|
||||
@start()
|
||||
def initialize_data(self):
|
||||
print("Initializing flow data")
|
||||
# Add key-value pairs to state
|
||||
self.state["user_name"] = "Alex"
|
||||
self.state["preferences"] = {
|
||||
"theme": "dark",
|
||||
"language": "English"
|
||||
}
|
||||
self.state["items"] = []
|
||||
|
||||
# The flow state automatically gets a unique ID
|
||||
print(f"Flow ID: {self.state['id']}")
|
||||
|
||||
return "Initialized"
|
||||
|
||||
@listen(initialize_data)
|
||||
def process_data(self, previous_result):
|
||||
print(f"Previous step returned: {previous_result}")
|
||||
|
||||
# Access and modify state
|
||||
user = self.state["user_name"]
|
||||
print(f"Processing data for {user}")
|
||||
|
||||
# Add items to a list in state
|
||||
self.state["items"].append("item1")
|
||||
self.state["items"].append("item2")
|
||||
|
||||
# Add a new key-value pair
|
||||
self.state["processed"] = True
|
||||
|
||||
return "Processed"
|
||||
|
||||
@listen(process_data)
|
||||
def generate_summary(self, previous_result):
|
||||
# Access multiple state values
|
||||
user = self.state["user_name"]
|
||||
theme = self.state["preferences"]["theme"]
|
||||
items = self.state["items"]
|
||||
processed = self.state.get("processed", False)
|
||||
|
||||
summary = f"User {user} has {len(items)} items with {theme} theme. "
|
||||
summary += "Data is processed." if processed else "Data is not processed."
|
||||
|
||||
return summary
|
||||
|
||||
# Run the flow
|
||||
flow = UnstructuredStateFlow()
|
||||
result = flow.kickoff()
|
||||
print(f"Final result: {result}")
|
||||
print(f"Final state: {flow.state}")
|
||||
```
|
||||
|
||||
### When to Use Unstructured State
|
||||
|
||||
Unstructured state is ideal for:
|
||||
- Quick prototyping and simple flows
|
||||
- Dynamically evolving state needs
|
||||
- Cases where the structure may not be known in advance
|
||||
- Flows with simple state requirements
|
||||
|
||||
While flexible, unstructured state lacks type checking and schema validation, which can lead to errors in complex applications.
|
||||
|
||||
## Structured State Management
|
||||
|
||||
Structured state uses Pydantic models to define a schema for your flow's state, providing type safety, validation, and better developer experience.
|
||||
|
||||
### How It Works
|
||||
|
||||
With structured state:
|
||||
- You define a Pydantic model that represents your state structure
|
||||
- You pass this model type to your Flow class as a type parameter
|
||||
- You access state via `self.state`, which behaves like a Pydantic model instance
|
||||
- All fields are validated according to their defined types
|
||||
- You get IDE autocompletion and type checking support
|
||||
|
||||
### Basic Example
|
||||
|
||||
Here's how to implement structured state management:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from pydantic import BaseModel, Field
|
||||
from typing import List, Dict, Optional
|
||||
|
||||
# Define your state model
|
||||
class UserPreferences(BaseModel):
|
||||
theme: str = "light"
|
||||
language: str = "English"
|
||||
|
||||
class AppState(BaseModel):
|
||||
user_name: str = ""
|
||||
preferences: UserPreferences = UserPreferences()
|
||||
items: List[str] = []
|
||||
processed: bool = False
|
||||
completion_percentage: float = 0.0
|
||||
|
||||
# Create a flow with typed state
|
||||
class StructuredStateFlow(Flow[AppState]):
|
||||
@start()
|
||||
def initialize_data(self):
|
||||
print("Initializing flow data")
|
||||
# Set state values (type-checked)
|
||||
self.state.user_name = "Taylor"
|
||||
self.state.preferences.theme = "dark"
|
||||
|
||||
# The ID field is automatically available
|
||||
print(f"Flow ID: {self.state.id}")
|
||||
|
||||
return "Initialized"
|
||||
|
||||
@listen(initialize_data)
|
||||
def process_data(self, previous_result):
|
||||
print(f"Processing data for {self.state.user_name}")
|
||||
|
||||
# Modify state (with type checking)
|
||||
self.state.items.append("item1")
|
||||
self.state.items.append("item2")
|
||||
self.state.processed = True
|
||||
self.state.completion_percentage = 50.0
|
||||
|
||||
return "Processed"
|
||||
|
||||
@listen(process_data)
|
||||
def generate_summary(self, previous_result):
|
||||
# Access state (with autocompletion)
|
||||
summary = f"User {self.state.user_name} has {len(self.state.items)} items "
|
||||
summary += f"with {self.state.preferences.theme} theme. "
|
||||
summary += "Data is processed." if self.state.processed else "Data is not processed."
|
||||
summary += f" Completion: {self.state.completion_percentage}%"
|
||||
|
||||
return summary
|
||||
|
||||
# Run the flow
|
||||
flow = StructuredStateFlow()
|
||||
result = flow.kickoff()
|
||||
print(f"Final result: {result}")
|
||||
print(f"Final state: {flow.state}")
|
||||
```
|
||||
|
||||
### Benefits of Structured State
|
||||
|
||||
Using structured state provides several advantages:
|
||||
|
||||
1. **Type Safety** - Catch type errors at development time
|
||||
2. **Self-Documentation** - The state model clearly documents what data is available
|
||||
3. **Validation** - Automatic validation of data types and constraints
|
||||
4. **IDE Support** - Get autocomplete and inline documentation
|
||||
5. **Default Values** - Easily define fallbacks for missing data
|
||||
|
||||
### When to Use Structured State
|
||||
|
||||
Structured state is recommended for:
|
||||
- Complex flows with well-defined data schemas
|
||||
- Team projects where multiple developers work on the same code
|
||||
- Applications where data validation is important
|
||||
- Flows that need to enforce specific data types and constraints
|
||||
|
||||
## The Automatic State ID
|
||||
|
||||
Both unstructured and structured states automatically receive a unique identifier (UUID) to help track and manage state instances.
|
||||
|
||||
### How It Works
|
||||
|
||||
- For unstructured state, the ID is accessible as `self.state["id"]`
|
||||
- For structured state, the ID is accessible as `self.state.id`
|
||||
- This ID is generated automatically when the flow is created
|
||||
- The ID remains the same throughout the flow's lifecycle
|
||||
- The ID can be used for tracking, logging, and retrieving persisted states
|
||||
|
||||
This UUID is particularly valuable when implementing persistence or tracking multiple flow executions.
|
||||
|
||||
## Dynamic State Updates
|
||||
|
||||
Regardless of whether you're using structured or unstructured state, you can update state dynamically throughout your flow's execution.
|
||||
|
||||
### Passing Data Between Steps
|
||||
|
||||
Flow methods can return values that are then passed as arguments to listening methods:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
|
||||
class DataPassingFlow(Flow):
|
||||
@start()
|
||||
def generate_data(self):
|
||||
# This return value will be passed to listening methods
|
||||
return "Generated data"
|
||||
|
||||
@listen(generate_data)
|
||||
def process_data(self, data_from_previous_step):
|
||||
print(f"Received: {data_from_previous_step}")
|
||||
# You can modify the data and pass it along
|
||||
processed_data = f"{data_from_previous_step} - processed"
|
||||
# Also update state
|
||||
self.state["last_processed"] = processed_data
|
||||
return processed_data
|
||||
|
||||
@listen(process_data)
|
||||
def finalize_data(self, processed_data):
|
||||
print(f"Received processed data: {processed_data}")
|
||||
# Access both the passed data and state
|
||||
last_processed = self.state.get("last_processed", "")
|
||||
return f"Final: {processed_data} (from state: {last_processed})"
|
||||
```
|
||||
|
||||
This pattern allows you to combine direct data passing with state updates for maximum flexibility.
|
||||
|
||||
## Persisting Flow State
|
||||
|
||||
One of CrewAI's most powerful features is the ability to persist flow state across executions. This enables workflows that can be paused, resumed, and even recovered after failures.
|
||||
|
||||
### The @persist() Decorator
|
||||
|
||||
The `@persist()` decorator automates state persistence, saving your flow's state at key points in execution.
|
||||
|
||||
#### Class-Level Persistence
|
||||
|
||||
When applied at the class level, `@persist()` saves state after every method execution:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from crewai.flow.persistence import persist
|
||||
from pydantic import BaseModel
|
||||
|
||||
class CounterState(BaseModel):
|
||||
value: int = 0
|
||||
|
||||
@persist() # Apply to the entire flow class
|
||||
class PersistentCounterFlow(Flow[CounterState]):
|
||||
@start()
|
||||
def increment(self):
|
||||
self.state.value += 1
|
||||
print(f"Incremented to {self.state.value}")
|
||||
return self.state.value
|
||||
|
||||
@listen(increment)
|
||||
def double(self, value):
|
||||
self.state.value = value * 2
|
||||
print(f"Doubled to {self.state.value}")
|
||||
return self.state.value
|
||||
|
||||
# First run
|
||||
flow1 = PersistentCounterFlow()
|
||||
result1 = flow1.kickoff()
|
||||
print(f"First run result: {result1}")
|
||||
|
||||
# Second run - state is automatically loaded
|
||||
flow2 = PersistentCounterFlow()
|
||||
result2 = flow2.kickoff()
|
||||
print(f"Second run result: {result2}") # Will be higher due to persisted state
|
||||
```
|
||||
|
||||
#### Method-Level Persistence
|
||||
|
||||
For more granular control, you can apply `@persist()` to specific methods:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from crewai.flow.persistence import persist
|
||||
|
||||
class SelectivePersistFlow(Flow):
|
||||
@start()
|
||||
def first_step(self):
|
||||
self.state["count"] = 1
|
||||
return "First step"
|
||||
|
||||
@persist() # Only persist after this method
|
||||
@listen(first_step)
|
||||
def important_step(self, prev_result):
|
||||
self.state["count"] += 1
|
||||
self.state["important_data"] = "This will be persisted"
|
||||
return "Important step completed"
|
||||
|
||||
@listen(important_step)
|
||||
def final_step(self, prev_result):
|
||||
self.state["count"] += 1
|
||||
return f"Complete with count {self.state['count']}"
|
||||
```
|
||||
|
||||
|
||||
## Advanced State Patterns
|
||||
|
||||
### State-Based Conditional Logic
|
||||
|
||||
You can use state to implement complex conditional logic in your flows:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, router, start
|
||||
from pydantic import BaseModel
|
||||
|
||||
class PaymentState(BaseModel):
|
||||
amount: float = 0.0
|
||||
is_approved: bool = False
|
||||
retry_count: int = 0
|
||||
|
||||
class PaymentFlow(Flow[PaymentState]):
|
||||
@start()
|
||||
def process_payment(self):
|
||||
# Simulate payment processing
|
||||
self.state.amount = 100.0
|
||||
self.state.is_approved = self.state.amount < 1000
|
||||
return "Payment processed"
|
||||
|
||||
@router(process_payment)
|
||||
def check_approval(self, previous_result):
|
||||
if self.state.is_approved:
|
||||
return "approved"
|
||||
elif self.state.retry_count < 3:
|
||||
return "retry"
|
||||
else:
|
||||
return "rejected"
|
||||
|
||||
@listen("approved")
|
||||
def handle_approval(self):
|
||||
return f"Payment of ${self.state.amount} approved!"
|
||||
|
||||
@listen("retry")
|
||||
def handle_retry(self):
|
||||
self.state.retry_count += 1
|
||||
print(f"Retrying payment (attempt {self.state.retry_count})...")
|
||||
# Could implement retry logic here
|
||||
return "Retry initiated"
|
||||
|
||||
@listen("rejected")
|
||||
def handle_rejection(self):
|
||||
return f"Payment of ${self.state.amount} rejected after {self.state.retry_count} retries."
|
||||
```
|
||||
|
||||
### Handling Complex State Transformations
|
||||
|
||||
For complex state transformations, you can create dedicated methods:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from pydantic import BaseModel
|
||||
from typing import List, Dict
|
||||
|
||||
class UserData(BaseModel):
|
||||
name: str
|
||||
active: bool = True
|
||||
login_count: int = 0
|
||||
|
||||
class ComplexState(BaseModel):
|
||||
users: Dict[str, UserData] = {}
|
||||
active_user_count: int = 0
|
||||
|
||||
class TransformationFlow(Flow[ComplexState]):
|
||||
@start()
|
||||
def initialize(self):
|
||||
# Add some users
|
||||
self.add_user("alice", "Alice")
|
||||
self.add_user("bob", "Bob")
|
||||
self.add_user("charlie", "Charlie")
|
||||
return "Initialized"
|
||||
|
||||
@listen(initialize)
|
||||
def process_users(self, _):
|
||||
# Increment login counts
|
||||
for user_id in self.state.users:
|
||||
self.increment_login(user_id)
|
||||
|
||||
# Deactivate one user
|
||||
self.deactivate_user("bob")
|
||||
|
||||
# Update active count
|
||||
self.update_active_count()
|
||||
|
||||
return f"Processed {len(self.state.users)} users"
|
||||
|
||||
# Helper methods for state transformations
|
||||
def add_user(self, user_id: str, name: str):
|
||||
self.state.users[user_id] = UserData(name=name)
|
||||
self.update_active_count()
|
||||
|
||||
def increment_login(self, user_id: str):
|
||||
if user_id in self.state.users:
|
||||
self.state.users[user_id].login_count += 1
|
||||
|
||||
def deactivate_user(self, user_id: str):
|
||||
if user_id in self.state.users:
|
||||
self.state.users[user_id].active = False
|
||||
self.update_active_count()
|
||||
|
||||
def update_active_count(self):
|
||||
self.state.active_user_count = sum(
|
||||
1 for user in self.state.users.values() if user.active
|
||||
)
|
||||
```
|
||||
|
||||
This pattern of creating helper methods keeps your flow methods clean while enabling complex state manipulations.
|
||||
|
||||
## State Management with Crews
|
||||
|
||||
One of the most powerful patterns in CrewAI is combining flow state management with crew execution.
|
||||
|
||||
### Passing State to Crews
|
||||
|
||||
You can use flow state to parameterize crews:
|
||||
|
||||
```python
|
||||
from crewai.flow.flow import Flow, listen, start
|
||||
from crewai import Agent, Crew, Process, Task
|
||||
from pydantic import BaseModel
|
||||
|
||||
class ResearchState(BaseModel):
|
||||
topic: str = ""
|
||||
depth: str = "medium"
|
||||
results: str = ""
|
||||
|
||||
class ResearchFlow(Flow[ResearchState]):
|
||||
@start()
|
||||
def get_parameters(self):
|
||||
# In a real app, this might come from user input
|
||||
self.state.topic = "Artificial Intelligence Ethics"
|
||||
self.state.depth = "deep"
|
||||
return "Parameters set"
|
||||
|
||||
@listen(get_parameters)
|
||||
def execute_research(self, _):
|
||||
# Create agents
|
||||
researcher = Agent(
|
||||
role="Research Specialist",
|
||||
goal=f"Research {self.state.topic} in {self.state.depth} detail",
|
||||
backstory="You are an expert researcher with a talent for finding accurate information."
|
||||
)
|
||||
|
||||
writer = Agent(
|
||||
role="Content Writer",
|
||||
goal="Transform research into clear, engaging content",
|
||||
backstory="You excel at communicating complex ideas clearly and concisely."
|
||||
)
|
||||
|
||||
# Create tasks
|
||||
research_task = Task(
|
||||
description=f"Research {self.state.topic} with {self.state.depth} analysis",
|
||||
expected_output="Comprehensive research notes in markdown format",
|
||||
agent=researcher
|
||||
)
|
||||
|
||||
writing_task = Task(
|
||||
description=f"Create a summary on {self.state.topic} based on the research",
|
||||
expected_output="Well-written article in markdown format",
|
||||
agent=writer,
|
||||
context=[research_task]
|
||||
)
|
||||
|
||||
# Create and run crew
|
||||
research_crew = Crew(
|
||||
agents=[researcher, writer],
|
||||
tasks=[research_task, writing_task],
|
||||
process=Process.sequential,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Run crew and store result in state
|
||||
result = research_crew.kickoff()
|
||||
self.state.results = result.raw
|
||||
|
||||
return "Research completed"
|
||||
|
||||
@listen(execute_research)
|
||||
def summarize_results(self, _):
|
||||
# Access the stored results
|
||||
result_length = len(self.state.results)
|
||||
return f"Research on {self.state.topic} completed with {result_length} characters of results."
|
||||
```
|
||||
|
||||
### Handling Crew Outputs in State
|
||||
|
||||
When a crew completes, you can process its output and store it in your flow state:
|
||||
|
||||
```python
|
||||
@listen(execute_crew)
|
||||
def process_crew_results(self, _):
|
||||
# Parse the raw results (assuming JSON output)
|
||||
import json
|
||||
try:
|
||||
results_dict = json.loads(self.state.raw_results)
|
||||
self.state.processed_results = {
|
||||
"title": results_dict.get("title", ""),
|
||||
"main_points": results_dict.get("main_points", []),
|
||||
"conclusion": results_dict.get("conclusion", "")
|
||||
}
|
||||
return "Results processed successfully"
|
||||
except json.JSONDecodeError:
|
||||
self.state.error = "Failed to parse crew results as JSON"
|
||||
return "Error processing results"
|
||||
```
|
||||
|
||||
## Best Practices for State Management
|
||||
|
||||
### 1. Keep State Focused
|
||||
|
||||
Design your state to contain only what's necessary:
|
||||
|
||||
```python
|
||||
# Too broad
|
||||
class BloatedState(BaseModel):
|
||||
user_data: Dict = {}
|
||||
system_settings: Dict = {}
|
||||
temporary_calculations: List = []
|
||||
debug_info: Dict = {}
|
||||
# ...many more fields
|
||||
|
||||
# Better: Focused state
|
||||
class FocusedState(BaseModel):
|
||||
user_id: str
|
||||
preferences: Dict[str, str]
|
||||
completion_status: Dict[str, bool]
|
||||
```
|
||||
|
||||
### 2. Use Structured State for Complex Flows
|
||||
|
||||
As your flows grow in complexity, structured state becomes increasingly valuable:
|
||||
|
||||
```python
|
||||
# Simple flow can use unstructured state
|
||||
class SimpleGreetingFlow(Flow):
|
||||
@start()
|
||||
def greet(self):
|
||||
self.state["name"] = "World"
|
||||
return f"Hello, {self.state['name']}!"
|
||||
|
||||
# Complex flow benefits from structured state
|
||||
class UserRegistrationState(BaseModel):
|
||||
username: str
|
||||
email: str
|
||||
verification_status: bool = False
|
||||
registration_date: datetime = Field(default_factory=datetime.now)
|
||||
last_login: Optional[datetime] = None
|
||||
|
||||
class RegistrationFlow(Flow[UserRegistrationState]):
|
||||
# Methods with strongly-typed state access
|
||||
```
|
||||
|
||||
### 3. Document State Transitions
|
||||
|
||||
For complex flows, document how state changes throughout the execution:
|
||||
|
||||
```python
|
||||
@start()
|
||||
def initialize_order(self):
|
||||
"""
|
||||
Initialize order state with empty values.
|
||||
|
||||
State before: {}
|
||||
State after: {order_id: str, items: [], status: 'new'}
|
||||
"""
|
||||
self.state.order_id = str(uuid.uuid4())
|
||||
self.state.items = []
|
||||
self.state.status = "new"
|
||||
return "Order initialized"
|
||||
```
|
||||
|
||||
### 4. Handle State Errors Gracefully
|
||||
|
||||
Implement error handling for state access:
|
||||
|
||||
```python
|
||||
@listen(previous_step)
|
||||
def process_data(self, _):
|
||||
try:
|
||||
# Try to access a value that might not exist
|
||||
user_preference = self.state.preferences.get("theme", "default")
|
||||
except (AttributeError, KeyError):
|
||||
# Handle the error gracefully
|
||||
self.state.errors = self.state.get("errors", [])
|
||||
self.state.errors.append("Failed to access preferences")
|
||||
user_preference = "default"
|
||||
|
||||
return f"Used preference: {user_preference}"
|
||||
```
|
||||
|
||||
### 5. Use State for Progress Tracking
|
||||
|
||||
Leverage state to track progress in long-running flows:
|
||||
|
||||
```python
|
||||
class ProgressTrackingFlow(Flow):
|
||||
@start()
|
||||
def initialize(self):
|
||||
self.state["total_steps"] = 3
|
||||
self.state["current_step"] = 0
|
||||
self.state["progress"] = 0.0
|
||||
self.update_progress()
|
||||
return "Initialized"
|
||||
|
||||
def update_progress(self):
|
||||
"""Helper method to calculate and update progress"""
|
||||
if self.state.get("total_steps", 0) > 0:
|
||||
self.state["progress"] = (self.state.get("current_step", 0) /
|
||||
self.state["total_steps"]) * 100
|
||||
print(f"Progress: {self.state['progress']:.1f}%")
|
||||
|
||||
@listen(initialize)
|
||||
def step_one(self, _):
|
||||
# Do work...
|
||||
self.state["current_step"] = 1
|
||||
self.update_progress()
|
||||
return "Step 1 complete"
|
||||
|
||||
# Additional steps...
|
||||
```
|
||||
|
||||
### 6. Use Immutable Operations When Possible
|
||||
|
||||
Especially with structured state, prefer immutable operations for clarity:
|
||||
|
||||
```python
|
||||
# Instead of modifying lists in place:
|
||||
self.state.items.append(new_item) # Mutable operation
|
||||
|
||||
# Consider creating new state:
|
||||
from pydantic import BaseModel
|
||||
from typing import List
|
||||
|
||||
class ItemState(BaseModel):
|
||||
items: List[str] = []
|
||||
|
||||
class ImmutableFlow(Flow[ItemState]):
|
||||
@start()
|
||||
def add_item(self):
|
||||
# Create new list with the added item
|
||||
self.state.items = [*self.state.items, "new item"]
|
||||
return "Item added"
|
||||
```
|
||||
|
||||
## Debugging Flow State
|
||||
|
||||
### Logging State Changes
|
||||
|
||||
When developing, add logging to track state changes:
|
||||
|
||||
```python
|
||||
import logging
|
||||
logging.basicConfig(level=logging.INFO)
|
||||
|
||||
class LoggingFlow(Flow):
|
||||
def log_state(self, step_name):
|
||||
logging.info(f"State after {step_name}: {self.state}")
|
||||
|
||||
@start()
|
||||
def initialize(self):
|
||||
self.state["counter"] = 0
|
||||
self.log_state("initialize")
|
||||
return "Initialized"
|
||||
|
||||
@listen(initialize)
|
||||
def increment(self, _):
|
||||
self.state["counter"] += 1
|
||||
self.log_state("increment")
|
||||
return f"Incremented to {self.state['counter']}"
|
||||
```
|
||||
|
||||
### State Visualization
|
||||
|
||||
You can add methods to visualize your state for debugging:
|
||||
|
||||
```python
|
||||
def visualize_state(self):
|
||||
"""Create a simple visualization of the current state"""
|
||||
import json
|
||||
from rich.console import Console
|
||||
from rich.panel import Panel
|
||||
|
||||
console = Console()
|
||||
|
||||
if hasattr(self.state, "model_dump"):
|
||||
# Pydantic v2
|
||||
state_dict = self.state.model_dump()
|
||||
elif hasattr(self.state, "dict"):
|
||||
# Pydantic v1
|
||||
state_dict = self.state.dict()
|
||||
else:
|
||||
# Unstructured state
|
||||
state_dict = dict(self.state)
|
||||
|
||||
# Remove id for cleaner output
|
||||
if "id" in state_dict:
|
||||
state_dict.pop("id")
|
||||
|
||||
state_json = json.dumps(state_dict, indent=2, default=str)
|
||||
console.print(Panel(state_json, title="Current Flow State"))
|
||||
```
|
||||
|
||||
