## CrewAI Security Policy
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.
We are committed to protecting the confidentiality, integrity, and availability of the CrewAI ecosystem. This policy explains how to report potential vulnerabilities and what you can expect from us when you do.
## 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
### Scope
- 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
We welcome reports for vulnerabilities that could impact:
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.
- CrewAI-maintained source code and repositories
- CrewAI-operated infrastructure and services
- Official CrewAI releases, packages, and distributions
Issues affecting clearly unaffiliated third-party services or user-generated content are out of scope, unless you can demonstrate a direct impact on CrewAI systems or customers.
### How to Report
- **Please do not** disclose vulnerabilities via public GitHub issues, pull requests, or social media.
- Email detailed reports to **security@crewai.com** with the subject line `Security Report`.
- If you need to share large files or sensitive artifacts, mention it in your email and we will coordinate a secure transfer method.
### What to Include
Providing comprehensive information enables us to validate the issue quickly:
- **Vulnerability overview** — a concise description and classification (e.g., RCE, privilege escalation)
- **Affected components** — repository, branch, tag, or deployed service along with relevant file paths or endpoints
- **Reproduction steps** — detailed, step-by-step instructions; include logs, screenshots, or screen recordings when helpful
- **Proof-of-concept** — exploit details or code that demonstrates the impact (if available)
- **Impact analysis** — severity assessment, potential exploitation scenarios, and any prerequisites or special configurations
### Our Commitment
- **Acknowledgement:** We aim to acknowledge your report within two business days.
- **Communication:** We will keep you informed about triage results, remediation progress, and planned release timelines.
- **Resolution:** Confirmed vulnerabilities will be prioritized based on severity and fixed as quickly as possible.
- **Recognition:** We currently do not run a bug bounty program; any rewards or recognition are issued at CrewAI's discretion.
### Coordinated Disclosure
We ask that you allow us a reasonable window to investigate and remediate confirmed issues before any public disclosure. We will coordinate publication timelines with you whenever possible.
### Safe Harbor
We will not pursue or support legal action against individuals who, in good faith:
- Follow this policy and refrain from violating any applicable laws
- Avoid privacy violations, data destruction, or service disruption
- Limit testing to systems in scope and respect rate limits and terms of service
If you are unsure whether your testing is covered, please contact us at **security@crewai.com** before proceeding.
At this time, we are not offering a bug bounty program. Any rewards will be at our discretion.

### 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:
```python
from crewai.flow.flow import Flow, listen, start, router, or_
from crewai import Crew, Agent, Task, Process
from pydantic import BaseModel
# Define structured state for precise control
class MarketState(BaseModel):
sentiment: str = "neutral"
confidence: float = 0.0
recommendations: list = []
class AdvancedAnalysisFlow(Flow[MarketState]):
@start()
def fetch_market_data(self):
# Demonstrate low-level control with structured state
self.state.sentiment = "analyzing"
return {"sector": "tech", "timeframe": "1W"} # These parameters match the task description template
@listen(fetch_market_data)
def analyze_with_crew(self, market_data):
# Show crew agency through specialized roles
analyst = Agent(
role="Senior Market Analyst",
goal="Conduct deep market analysis with expert insight",
backstory="You're a veteran analyst known for identifying subtle market patterns"
)
researcher = Agent(
role="Data Researcher",
goal="Gather and validate supporting market data",
backstory="You excel at finding and correlating multiple data sources"
)
analysis_task = Task(
description="Analyze {sector} sector data for the past {timeframe}",
expected_output="Detailed market analysis with confidence score",
agent=analyst
)
research_task = Task(
description="Find supporting data to validate the analysis",
expected_output="Corroborating evidence and potential contradictions",
agent=researcher
)
# Demonstrate crew autonomy
analysis_crew = Crew(
agents=[analyst, researcher],
tasks=[analysis_task, research_task],
process=Process.sequential,
verbose=True
)
return analysis_crew.kickoff(inputs=market_data) # Pass market_data as named inputs
@router(analyze_with_crew)
def determine_next_steps(self):
# Show flow control with conditional routing
if self.state.confidence > 0.8:
return "high_confidence"
elif self.state.confidence > 0.5:
return "medium_confidence"
return "low_confidence"
@listen("high_confidence")
def execute_strategy(self):
# Demonstrate complex decision making
strategy_crew = Crew(
agents=[
Agent(role="Strategy Expert",
goal="Develop optimal market strategy")
],
tasks=[
Task(description="Create detailed strategy based on analysis",
expected_output="Step-by-step action plan")
]
)
return strategy_crew.kickoff()
@listen(or_("medium_confidence", "low_confidence"))
def request_additional_analysis(self):
self.state.recommendations.append("Gather more data")
return "Additional analysis required"
```
This example demonstrates how to:
1. Use Python code for basic data operations
2. Create and execute Crews as steps in your workflow
3. Use Flow decorators to manage the sequence of operations
4. Implement conditional branching based on Crew results
## 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 your agents' connections to models.
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 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.
**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.
- **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.
- **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.
*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.

## 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>
## Direct Agent Interaction with `kickoff()`
Agents can be used directly without going through a task or crew workflow using the `kickoff()` method. This provides a simpler way to interact with an agent when you don't need the full crew orchestration capabilities.
### How `kickoff()` Works
The `kickoff()` method allows you to send messages directly to an agent and get a response, similar to how you would interact with an LLM but with all the agent's capabilities (tools, reasoning, etc.).
```python Code
from crewai import Agent
from crewai_tools import SerperDevTool
# Create an agent
researcher = Agent(
role="AI Technology Researcher",
goal="Research the latest AI developments",
tools=[SerperDevTool()],
verbose=True
)
# Use kickoff() to interact directly with the agent
result = researcher.kickoff("What are the latest developments in language models?")
# Access the raw response
print(result.raw)
```
### Parameters and Return Values
| Parameter | Type | Description |
| :---------------- | :---------------------------------- | :------------------------------------------------------------------------ |
| `messages` | `Union[str, List[Dict[str, str]]]` | Either a string query or a list of message dictionaries with role/content |
| `response_format` | `Optional[Type[Any]]` | Optional Pydantic model for structured output |
The method returns a `LiteAgentOutput` object with the following properties:
- `raw`: String containing the raw output text
- `pydantic`: Parsed Pydantic model (if a `response_format` was provided)
- `agent_role`: Role of the agent that produced the output
- `usage_metrics`: Token usage metrics for the execution
### Structured Output
You can get structured output by providing a Pydantic model as the `response_format`:
```python Code
from pydantic import BaseModel
from typing import List
class ResearchFindings(BaseModel):
main_points: List[str]
key_technologies: List[str]
future_predictions: str
# Get structured output
result = researcher.kickoff(
"Summarize the latest developments in AI for 2025",
response_format=ResearchFindings
)
# Access structured data
print(result.pydantic.main_points)
print(result.pydantic.future_predictions)
```
### Multiple Messages
You can also provide a conversation history as a list of message dictionaries:
```python Code
messages = [
{"role": "user", "content": "I need information about large language models"},
{"role": "assistant", "content": "I'd be happy to help with that! What specifically would you like to know?"},
{"role": "user", "content": "What are the latest developments in 2025?"}
]
result = researcher.kickoff(messages)
```
### Async Support
An asynchronous version is available via `kickoff_async()` with the same parameters:
```python Code
import asyncio
async def main():
result = await researcher.kickoff_async("What are the latest developments in AI?")
print(result.raw)
asyncio.run(main())
```
<Note>
The `kickoff()` method uses a `LiteAgent` internally, which provides a simpler execution flow while preserving all of the agent's configuration (role, goal, backstory, tools, etc.).

## Collaboration Fundamentals
Collaboration in CrewAI is fundamental, enabling agents to combine their skills, share information, and assist each other in task execution, embodying a truly cooperative ecosystem.
- **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
The `Crew` class has been enriched with several attributes to support advanced functionalities:
| Feature | Description |
|:-------------------------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Language Model Management** (`manager_llm`, `function_calling_llm`) | Manages language models for executing tasks and tools. `manager_llm` is required for hierarchical processes, while `function_calling_llm` is optional with a default value for streamlined interactions. |
| **Custom Manager Agent** (`manager_agent`) | Specifies a custom agent as the manager, replacing the default CrewAI manager. |
| **Process Flow** (`process`) | Defines execution logic (e.g., sequential, hierarchical) for task distribution. |
| **Verbose Logging** (`verbose`) | Provides detailed logging for monitoring and debugging. Accepts integer and boolean values to control verbosity level. |
| **Rate Limiting** (`max_rpm`) | Limits requests per minute to optimize resource usage. Setting guidelines depend on task complexity and load. |
| **Internationalization / Customization** (`language`, `prompt_file`) | Supports prompt customization for global usability. [Example of file](https://github.com/joaomdmoura/crewAI/blob/main/src/crewai/translations/en.json) |
| **Execution and Output Handling** (`full_output`) | Controls output granularity, distinguishing between full and final outputs. |
| **Callback and Telemetry** (`step_callback`, `task_callback`) | Enables step-wise and task-level execution monitoring and telemetry for performance analytics. |
| **Crew Sharing** (`share_crew`) | Allows sharing crew data with CrewAI for model improvement. Privacy implications and benefits should be considered. |
| **Usage Metrics** (`usage_metrics`) | Logs all LLM usage metrics during task execution for performance insights. |
| **Memory Usage** (`memory`) | Enables memory for storing execution history, aiding in agent learning and task efficiency. |
| **Embedder Configuration** (`embedder`) | Configures the embedder for language understanding and generation, with support for provider customization. |
| **Cache Management** (`cache`) | Specifies whether to cache tool execution results, enhancing performance. |
| **Output Logging** (`output_log_file`) | Defines the file path for logging crew execution output. |
| **Planning Mode** (`planning`) | Enables action planning before task execution. Set `planning=True` to activate. |
| **Replay Feature** (`replay`) | Provides CLI for listing tasks from the last run and replaying from specific tasks, aiding in task management and troubleshooting. |
## Delegation (Dividing to Conquer)
Delegation enhances functionality by allowing agents to intelligently assign tasks or seek help, thereby amplifying the crew's overall capability.
## Implementing Collaboration and Delegation
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.
## Example Scenario
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.
## Conclusion
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.

![Flow Visual image](/images/crewai-flow-1.png)
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.
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.
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.
**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.
### @start()
The `@start()` decorator marks entry points for a Flow. You can:
- Declare multiple unconditional starts: `@start()`
- Gate a start on a prior method or router label: `@start("method_or_label")`
- Provide a callable condition to control when a start should fire
All satisfied `@start()` methods will execute (often in parallel) when the Flow begins or resumes.
The `@start()` decorator is used to mark a method as the starting point of a Flow. When a Flow is started, all the methods decorated with `@start()` are executed in parallel. You can have multiple start methods in a Flow, and they will all be executed when the Flow is started.

In unstructured state management, all state is stored in the `state` attribute of the `Flow` class.

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.

## 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.

# Using Knowledge in CrewAI
## What is Knowledge?
Knowledge in CrewAI is a powerful system that allows AI agents to access and utilize external information sources during their tasks.
Think of it as giving your agents a reference library they can consult while working.
<Info>
Key benefits of using Knowledge:
- Enhance agents with domain-specific information
- Support decisions with real-world data
- Maintain context across conversations
- Ground responses in factual information
</Info>
## Supported Knowledge Sources
CrewAI supports various types of knowledge sources out of the box:
<CardGroup cols={2}>
<Card title="Text Sources" icon="text">
- Raw strings
- Text files (.txt)
- PDF documents
</Card>
<Card title="Structured Data" icon="table">
- CSV files
- Excel spreadsheets
- JSON documents
</Card>
</CardGroup>
## Quick Start
Here's an example using string-based knowledge:
```python Code
from crewai import Agent, Task, Crew, Process, LLM
from crewai.knowledge.source.string_knowledge_source import StringKnowledgeSource
# Create a knowledge source
content = "Users name is John. He is 30 years old and lives in San Francisco."
string_source = StringKnowledgeSource(
content=content,
)
# Create an LLM with a temperature of 0 to ensure deterministic outputs
llm = LLM(model="gpt-4o-mini", temperature=0)
# Create an agent with the knowledge store
agent = Agent(
role="About User",
goal="You know everything about the user.",
backstory="""You are a master at understanding people and their preferences.""",
verbose=True,
allow_delegation=False,
llm=llm,
)
task = Task(
description="Answer the following questions about the user: {question}",
expected_output="An answer to the question.",
agent=agent,
)
crew = Crew(
agents=[agent],
tasks=[task],
verbose=True,
process=Process.sequential,
knowledge_sources=[string_source], # Enable knowledge by adding the sources here. You can also add more sources to the sources list.
)
result = crew.kickoff(inputs={"question": "What city does John live in and how old is he?"})
```
## Knowledge Configuration
### Chunking Configuration
Control how content is split for processing by setting the chunk size and overlap.
```python Code
knowledge_source = StringKnowledgeSource(
content="Long content...",
chunk_size=4000, # Characters per chunk (default)
chunk_overlap=200 # Overlap between chunks (default)
)
```
## Embedder Configuration
You can also configure the embedder for the knowledge store. This is useful if you want to use a different embedder for the knowledge store than the one used for the agents.
```python Code
...
string_source = StringKnowledgeSource(
content="Users name is John. He is 30 years old and lives in San Francisco.",
)
crew = Crew(
...
knowledge_sources=[string_source],
embedder={
"provider": "openai",
"config": {"model": "text-embedding-3-small"},
},
)
```
## Clearing Knowledge
If you need to clear the knowledge stored in CrewAI, you can use the `crewai reset-memories` command with the `--knowledge` option.
```bash Command
crewai reset-memories --knowledge
```
This is useful when you've updated your knowledge sources and want to ensure that the agents are using the most recent information.
## Custom Knowledge Sources
CrewAI allows you to create custom knowledge sources for any type of data by extending the `BaseKnowledgeSource` class. Let's create a practical example that fetches and processes space news articles.
#### Space News Knowledge Source Example
<CodeGroup>
```python Code
from crewai import Agent, Task, Crew, Process, LLM
from crewai.knowledge.source.base_knowledge_source import BaseKnowledgeSource
import requests
from datetime import datetime
from typing import Dict, Any
from pydantic import BaseModel, Field
class SpaceNewsKnowledgeSource(BaseKnowledgeSource):
"""Knowledge source that fetches data from Space News API."""
api_endpoint: str = Field(description="API endpoint URL")
limit: int = Field(default=10, description="Number of articles to fetch")
def load_content(self) -> Dict[Any, str]:
"""Fetch and format space news articles."""
try:
response = requests.get(
f"{self.api_endpoint}?limit={self.limit}"
)
response.raise_for_status()
data = response.json()
articles = data.get('results', [])
formatted_data = self._format_articles(articles)
return {self.api_endpoint: formatted_data}
except Exception as e:
raise ValueError(f"Failed to fetch space news: {str(e)}")
def _format_articles(self, articles: list) -> str:
"""Format articles into readable text."""
formatted = "Space News Articles:\n\n"
for article in articles:
formatted += f"""
Title: {article['title']}
Published: {article['published_at']}
Summary: {article['summary']}
News Site: {article['news_site']}
URL: {article['url']}
-------------------"""
return formatted
def add(self) -> None:
"""Process and store the articles."""
content = self.load_content()
for _, text in content.items():
chunks = self._chunk_text(text)
self.chunks.extend(chunks)
self._save_documents()
# Create knowledge source
recent_news = SpaceNewsKnowledgeSource(
api_endpoint="https://api.spaceflightnewsapi.net/v4/articles",
limit=10,
)
# Create specialized agent
space_analyst = Agent(
role="Space News Analyst",
goal="Answer questions about space news accurately and comprehensively",
backstory="""You are a space industry analyst with expertise in space exploration,
satellite technology, and space industry trends. You excel at answering questions
about space news and providing detailed, accurate information.""",
knowledge_sources=[recent_news],
llm=LLM(model="gpt-4", temperature=0.0)
)
# Create task that handles user questions
analysis_task = Task(
description="Answer this question about space news: {user_question}",
expected_output="A detailed answer based on the recent space news articles",
agent=space_analyst
)
# Create and run the crew
crew = Crew(
agents=[space_analyst],
tasks=[analysis_task],
verbose=True,
process=Process.sequential
)
# Example usage
result = crew.kickoff(
inputs={"user_question": "What are the latest developments in space exploration?"}
)
```
```output Output
# Agent: Space News Analyst
## Task: Answer this question about space news: What are the latest developments in space exploration?
# Agent: Space News Analyst

#### Key Components Explained
1. **Custom Knowledge Source (`SpaceNewsKnowledgeSource`)**:
- Extends `BaseKnowledgeSource` for integration with CrewAI
- Configurable API endpoint and article limit
- Implements three key methods:
- `load_content()`: Fetches articles from the API
- `_format_articles()`: Structures the articles into readable text
- `add()`: Processes and stores the content
2. **Agent Configuration**:
- Specialized role as a Space News Analyst
- Uses the knowledge source to access space news
3. **Task Setup**:
- Takes a user question as input through `{user_question}`
- Designed to provide detailed answers based on the knowledge source
4. **Crew Orchestration**:
- Manages the workflow between agent and task
- Handles input/output through the kickoff method
This example demonstrates how to:
- Create a custom knowledge source that fetches real-time data
- Process and format external data for AI consumption
- Use the knowledge source to answer specific user questions
- Integrate everything seamlessly with CrewAI's agent system
#### About the Spaceflight News API
The example uses the [Spaceflight News API](https://api.spaceflightnewsapi.net/v4/docs/), which:
- Provides free access to space-related news articles
- Requires no authentication
- Returns structured data about space news
- Supports pagination and filtering
You can customize the API query by modifying the endpoint URL:
```python
# Fetch more articles
recent_news = SpaceNewsKnowledgeSource(
api_endpoint="https://api.spaceflightnewsapi.net/v4/articles",
limit=20, # Increase the number of articles
)
# Add search parameters
recent_news = SpaceNewsKnowledgeSource(
api_endpoint="https://api.spaceflightnewsapi.net/v4/articles?search=NASA", # Search for NASA news
limit=10,
)
```

title: 'LLMs'
description: 'A comprehensive guide to configuring and using Large Language Models (LLMs) in your CrewAI projects'
icon: 'microchip-ai'
---
<Note>
CrewAI integrates with multiple LLM providers through LiteLLM, giving you the flexibility to choose the right model for your specific use case. This guide will help you understand how to configure and use different LLM providers in your CrewAI projects.
</Note>
## What are LLMs?
Large Language Models (LLMs) are the core intelligence behind CrewAI agents. They enable agents to understand context, make decisions, and generate human-like responses. Here's what you need to know:
<CardGroup cols={2}>
<Card title="LLM Basics" icon="brain">
Large Language Models are AI systems trained on vast amounts of text data. They power the intelligence of your CrewAI agents, enabling them to understand and generate human-like text.
</Card>
<Card title="Context Window" icon="window">
The context window determines how much text an LLM can process at once. Larger windows (e.g., 128K tokens) allow for more context but may be more expensive and slower.
</Card>
<Card title="Temperature" icon="temperature-three-quarters">
Temperature (0.0 to 1.0) controls response randomness. Lower values (e.g., 0.2) produce more focused, deterministic outputs, while higher values (e.g., 0.8) increase creativity and variability.
</Card>
<Card title="Provider Selection" icon="server">
Each LLM provider (e.g., OpenAI, Anthropic, Google) offers different models with varying capabilities, pricing, and features. Choose based on your needs for accuracy, speed, and cost.
</Card>
</CardGroup>
## Available Models and Their Capabilities
Here's a detailed breakdown of supported models and their capabilities:

</Info>
</Tab>
</Tabs>
## Setting Up Your LLM
There are three ways to configure LLMs in CrewAI. Choose the method that best fits your workflow:
<Tabs>
<Tab title="1. Environment Variables">
The simplest way to get started. Set these variables in your environment:
```bash
# Required: Your API key for authentication
OPENAI_API_KEY=<your-api-key>
# Optional: Default model selection
OPENAI_MODEL_NAME=gpt-4o-mini # Default if not set
# Optional: Organization ID (if applicable)
OPENAI_ORGANIZATION_ID=<your-org-id>
```
<Warning>
Never commit API keys to version control. Use environment files (.env) or your system's secret management.
</Warning>
</Tab>
<Tab title="2. YAML Configuration">
Create a YAML file to define your agent configurations. This method is great for version control and team collaboration:
```yaml

<Info>
The YAML configuration allows you to:
- Version control your agent settings
- Easily switch between different models
- Share configurations across team members
- Document model choices and their purposes
</Info>
</Tab>
<Tab title="3. Direct Code">
For maximum flexibility, configure LLMs directly in your Python code:

title: Memory
description: Leveraging memory systems in the CrewAI framework to enhance agent capabilities.
icon: database
---
## Introduction to Memory Systems in CrewAI
The crewAI framework introduces a sophisticated memory system designed to significantly enhance the capabilities of AI agents.
This system comprises `short-term memory`, `long-term memory`, `entity memory`, and `contextual memory`, each serving a unique purpose in aiding agents to remember,
reason, and learn from past interactions.
## Memory System Components
| Component | Description |
| :------------------- | :---------------------------------------------------------------------------------------------------------------------- |
| **Short-Term Memory**| Temporarily stores recent interactions and outcomes using `RAG`, enabling agents to recall and utilize information relevant to their current context during the current executions.|
| **Long-Term Memory** | Preserves valuable insights and learnings from past executions, allowing agents to build and refine their knowledge over time. |
| **Entity Memory** | Captures and organizes information about entities (people, places, concepts) encountered during tasks, facilitating deeper understanding and relationship mapping. Uses `RAG` for storing entity information. |
| **Contextual Memory**| Maintains the context of interactions by combining `ShortTermMemory`, `LongTermMemory`, and `EntityMemory`, aiding in the coherence and relevance of agent responses over a sequence of tasks or a conversation. |
| **User Memory** | Stores user-specific information and preferences, enhancing personalization and user experience. |
## How Memory Systems Empower Agents
1. **Contextual Awareness**: With short-term and contextual memory, agents gain the ability to maintain context over a conversation or task sequence, leading to more coherent and relevant responses.
2. **Experience Accumulation**: Long-term memory allows agents to accumulate experiences, learning from past actions to improve future decision-making and problem-solving.
3. **Entity Understanding**: By maintaining entity memory, agents can recognize and remember key entities, enhancing their ability to process and interact with complex information.
## Implementing Memory in Your Crew
When configuring a crew, you can enable and customize each memory component to suit the crew's objectives and the nature of tasks it will perform.
By default, the memory system is disabled, and you can ensure it is active by setting `memory=True` in the crew configuration.
The memory will use OpenAI embeddings by default, but you can change it by setting `embedder` to a different model.
It's also possible to initialize the memory instance with your own instance.
The 'embedder' only applies to **Short-Term Memory** which uses Chroma for RAG.
The **Long-Term Memory** uses SQLite3 to store task results. Currently, there is no way to override these storage implementations.
The data storage files are saved into a platform-specific location found using the appdirs package,
and the name of the project can be overridden using the **CREWAI_STORAGE_DIR** environment variable.
### Example: Configuring Memory for a Crew
```python Code
from crewai import Crew, Agent, Task, Process
# Assemble your crew with memory capabilities
my_crew = Crew(
agents=[...],
tasks=[...],
process=Process.sequential,
memory=True,
verbose=True
)
```
### Example: Use Custom Memory Instances e.g FAISS as the VectorDB
```python Code
from crewai import Crew, Agent, Task, Process
# Assemble your crew with memory capabilities
my_crew = Crew(
agents=[...],
tasks=[...],
process="Process.sequential",
memory=True,
long_term_memory=EnhanceLongTermMemory(
storage=LTMSQLiteStorage(
db_path="/my_data_dir/my_crew1/long_term_memory_storage.db"
)
),
short_term_memory=EnhanceShortTermMemory(
storage=CustomRAGStorage(
crew_name="my_crew",
storage_type="short_term",
data_dir="//my_data_dir",
model=embedder["model"],
dimension=embedder["dimension"],
),
),
entity_memory=EnhanceEntityMemory(
storage=CustomRAGStorage(
crew_name="my_crew",
storage_type="entities",
data_dir="//my_data_dir",
model=embedder["model"],
dimension=embedder["dimension"],
),
),
verbose=True,
)
```
## Integrating Mem0 for Enhanced User Memory
[Mem0](https://mem0.ai/) is a self-improving memory layer for LLM applications, enabling personalized AI experiences.
To include user-specific memory you can get your API key [here](https://app.mem0.ai/dashboard/api-keys) and refer the [docs](https://docs.mem0.ai/platform/quickstart#4-1-create-memories) for adding user preferences.
```python Code
import os
from crewai import Crew, Process
from mem0 import MemoryClient
# Set environment variables for Mem0
os.environ["MEM0_API_KEY"] = "m0-xx"
# Step 1: Record preferences based on past conversation or user input
client = MemoryClient()
messages = [
{"role": "user", "content": "Hi there! I'm planning a vacation and could use some advice."},
{"role": "assistant", "content": "Hello! I'd be happy to help with your vacation planning. What kind of destination do you prefer?"},
{"role": "user", "content": "I am more of a beach person than a mountain person."},
{"role": "assistant", "content": "That's interesting. Do you like hotels or Airbnb?"},
{"role": "user", "content": "I like Airbnb more."},
]
client.add(messages, user_id="john")
# Step 2: Create a Crew with User Memory
crew = Crew(
agents=[...],
tasks=[...],
verbose=True,
process=Process.sequential,
memory=True,
memory_config={
"provider": "mem0",
"config": {"user_id": "john"},
},
)
```
## Additional Embedding Providers

## 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.

## 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.
Guardrails are implemented as Python functions that contain custom validation logic, giving you complete control over the validation process and ensuring reliable, deterministic results.
### Function-Based Guardrails
To add a function-based 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")`
### 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 (`guardrail_max_retries`)
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,
guardrail_max_retries=3 # Limit retry attempts
)
```
## Getting Structured Consistent Outputs from Tasks
When you need to ensure that a task outputs a structured and consistent format, you can use the `output_pydantic` or `output_json` properties on a task. These properties allow you to define the expected output structure, making it easier to parse and utilize the results in your application.

## Creating Directories when Saving Files
The `create_directory` parameter controls whether CrewAI should automatically create directories when saving task outputs to files. This feature is particularly useful for organizing outputs and ensuring that file paths are correctly structured, especially when working with complex project hierarchies.
### Default Behavior
By default, `create_directory=True`, which means CrewAI will automatically create any missing directories in the output file path:
You can now specify if a task should create directories when saving its output to a file. This is particularly useful for organizing outputs and ensuring that file paths are correctly structured.
```python Code
# Default behavior - directories are created automatically
report_task = Task(
description='Generate a comprehensive market analysis report',
expected_output='A detailed market analysis with charts and insights',
agent=analyst_agent,
output_file='reports/2025/market_analysis.md', # Creates 'reports/2025/' if it doesn't exist
markdown=True
# ...
save_output_task = Task(
description='Save the summarized AI news to a file',
expected_output='File saved successfully',
agent=research_agent,
tools=[file_save_tool],
output_file='outputs/ai_news_summary.txt',
create_directory=True
)
#...
```
### Disabling Directory Creation
If you want to prevent automatic directory creation and ensure that the directory already exists, set `create_directory=False`:
```python Code
# Strict mode - directory must already exist
strict_output_task = Task(
description='Save critical data that requires existing infrastructure',
expected_output='Data saved to pre-configured location',
agent=data_agent,
output_file='secure/vault/critical_data.json',
create_directory=False # Will raise RuntimeError if 'secure/vault/' doesn't exist
)
```
### YAML Configuration
You can also configure this behavior in your YAML task definitions:
```yaml tasks.yaml
analysis_task:
description: >
Generate quarterly financial analysis
expected_output: >
A comprehensive financial report with quarterly insights
agent: financial_analyst
output_file: reports/quarterly/q4_2024_analysis.pdf
create_directory: true # Automatically create 'reports/quarterly/' directory
audit_task:
description: >
Perform compliance audit and save to existing audit directory
expected_output: >
A compliance audit report
agent: auditor
output_file: audit/compliance_report.md
create_directory: false # Directory must already exist
```
### Use Cases
**Automatic Directory Creation (`create_directory=True`):**
- Development and prototyping environments
- Dynamic report generation with date-based folders
- Automated workflows where directory structure may vary
- Multi-tenant applications with user-specific folders
**Manual Directory Management (`create_directory=False`):**
- Production environments with strict file system controls
- Security-sensitive applications where directories must be pre-configured
- Systems with specific permission requirements
- Compliance environments where directory creation is audited
### Error Handling
When `create_directory=False` and the directory doesn't exist, CrewAI will raise a `RuntimeError`:
```python Code
try:
result = crew.kickoff()
except RuntimeError as e:
# Handle missing directory error
print(f"Directory creation failed: {e}")
# Create directory manually or use fallback location
```

# Your tool's logic here
return "Tool's result"
# Implementation goes here
return "Result from custom tool"
```
## 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.

### Structured Tools
The `StructuredTool` class wraps functions as tools, providing flexibility and validation while reducing boilerplate. It supports custom schemas and dynamic logic for seamless integration of complex functionalities.
#### Example:
Using `StructuredTool.from_function`, you can wrap a function that interacts with an external API or system, providing a structured interface. This enables robust validation and consistent execution, making it easier to integrate complex functionalities into your applications as demonstrated in the following example:
```python
from crewai.tools.structured_tool import CrewStructuredTool
from pydantic import BaseModel
# Define the schema for the tool's input using Pydantic
class APICallInput(BaseModel):
endpoint: str
parameters: dict
# Wrapper function to execute the API call
def tool_wrapper(*args, **kwargs):
# Here, you would typically call the API using the parameters
# For demonstration, we'll return a placeholder string
return f"Call the API at {kwargs['endpoint']} with parameters {kwargs['parameters']}"
# Create and return the structured tool
def create_structured_tool():
return CrewStructuredTool.from_function(
name='Wrapper API',
description="A tool to wrap API calls with structured input.",
args_schema=APICallInput,
func=tool_wrapper,
)
# Example usage
structured_tool = create_structured_tool()
# Execute the tool with structured input
result = structured_tool._run(**{
"endpoint": "https://example.com/api",
"parameters": {"key1": "value1", "key2": "value2"}
})

## Introduction
The training feature in CrewAI allows you to train your AI agents using the command-line interface (CLI).
By running the command `crewai train -n <n_iterations>`, you can specify the number of iterations for the training process.
During training, CrewAI utilizes techniques to optimize the performance of your agents along with human feedback.
This helps the agents improve their understanding, decision-making, and problem-solving abilities.
### Training Your Crew Using the CLI
To use the training feature, follow these steps:
1. Open your terminal or command prompt.
2. Navigate to the directory where your CrewAI project is located.
3. Run the following command:
```shell
crewai train -n <n_iterations> <filename> (optional)
```
<Tip>
Replace `<n_iterations>` with the desired number of training iterations and `<filename>` with the appropriate filename ending with `.pkl`.
</Tip>
### Training Your Crew Programmatically
To train your crew programmatically, use the following steps:
1. Define the number of iterations for training.
2. Specify the input parameters for the training process.
3. Execute the training command within a try-except block to handle potential errors.
```python Code
n_iterations = 2
inputs = {"topic": "CrewAI Training"}
filename = "your_model.pkl"
try:
YourCrewName_Crew().crew().train(
n_iterations=n_iterations,
inputs=inputs,
filename=filename
)
except Exception as e:
raise Exception(f"An error occurred while training the crew: {e}")
```
### Key Points to Note
- **Positive Integer Requirement:** Ensure that the number of iterations (`n_iterations`) is a positive integer. The code will raise a `ValueError` if this condition is not met.
- **Filename Requirement:** Ensure that the filename ends with `.pkl`. The code will raise a `ValueError` if this condition is not met.
- **Error Handling:** The code handles subprocess errors and unexpected exceptions, providing error messages to the user.
It is important to note that the training process may take some time, depending on the complexity of your agents and will also require your feedback on each iteration.
Once the training is complete, your agents will be equipped with enhanced capabilities and knowledge, ready to tackle complex tasks and provide more consistent and valuable insights.
Remember to regularly update and retrain your agents to ensure they stay up-to-date with the latest information and advancements in the field.
Happy training with CrewAI! 🚀
