ced3c8f0e0 Unblock LLM(stream=True) to work with tools (#2582)
* feat: unblock LLM(stream=True) to work with tools

* feat: replace pytest-vcr by pytest-recording

1. pytest-vcr does not support httpx - which LiteLLM uses for streaming responses.
2. pytest-vcr is no longer maintained, last commit 6 years ago :fist::skin-tone-4:
3. pytest-recording supports modern request libraries (including httpx) and actively maintained

* refactor: remove @skip_streaming_in_ci

Since we have fixed streaming response issue we can remove this @skip_streaming_in_ci

9dffd42e6d feat: Enhance memory system with isolated memory configuration (#2597)
* feat: support defining any memory in an isolated way

This change makes it easier to use a specific memory type without unintentionally enabling all others.

Previously, setting memory=True would implicitly configure all available memories (like LTM and STM), which might not be ideal in all cases. For example, when building a chatbot that only needs an external memory, users were forced to also configure LTM and STM — which rely on default OpenAPI embeddings — even if they weren’t needed.

With this update, users can now define a single memory in isolation, making the configuration process simpler and more flexible.

* feat: add tests to ensure we are able to use contextual memory by set individual memories

* docs: enhance memory documentation

* feat: warn when long-term memory is defined but entity memory is not

* style: Fix import order in tests/crew_test.py

Co-Authored-By: Joe Moura <joao@crewai.com>

* fix: Rely on validator for memory copy, update test assertions

Removes manual deep copy of memory objects in Crew.copy().
The Pydantic model_validator 'create_crew_memory' handles the
initialization of new memory instances for the copied crew.

Updates test_crew_copy_with_memory assertions to verify that
the private memory attributes (_short_term_memory, etc.) are
correctly initialized as new instances in the copied crew.

Co-Authored-By: Joe Moura <joao@crewai.com>

* Revert "fix: Rely on validator for memory copy, update test assertions"

This reverts commit 8702bf1e34.

* fix: Re-add manual deep copy for all memory types in Crew.copy

Addresses feedback on PR #2594 to ensure all memory objects
(short_term, long_term, entity, external, user) are correctly
deep copied using model_copy(deep=True).

Also simplifies the test case to directly verify the copy behavior
instead of relying on the train method.

5780c3147a fix: correct parameter name in crew template test function (#2567)
This commit resolves an issue in the crew template generator where the test() 
function incorrectly uses 'openai_model_name' as a parameter name when calling 
Crew.test(), while the actual implementation expects 'eval_llm'.

The mismatch causes a TypeError when users run the generated test command:
"Crew.test() got an unexpected keyword argument 'openai_model_name'"

This change ensures that templates generated with 'crewai create crew' will 
produce code that aligns with the framework's API.

d7fa8464c7 Add support for External Memory (the future replacement for UserMemory) (#2510)
* fix: surfacing properly supported types by Mem0Storage

* feat: prepare Mem0Storage to accept config paramenter

We're planning to remove `memory_config` soon. This commit kindly prepare this storage to accept the config provided directly

* feat: add external memory

* fix: cleanup Mem0 warning while adding messages to the memory

* feat: support set the current crew in memory

This can be useful when a memory is initialized before the crew, but the crew might still be a very relevant attribute

* fix: allow to reset only an external_memory from crew

* test: add external memory test

* test: ensure the config takes precedence over memory_config when setting mem0

* fix: support to provide a custom storage to External Memory

* docs: add docs about external memory

* chore: add warning messages about the deprecation of UserMemory

* fix: fix typing check

b6d668fc66 Implement Flow state export method (#2134)
This commit implements a method for exporting the state of a flow into a
JSON-serializable dictionary.

The idea is producing a human-readable version of state that can be
inspected or consumed by other systems, hence JSON and not pickling or
marshalling.

I consider it an export because it's a one-way process, meaning it
cannot be loaded back into Python because of complex types.

d6800d8957 Ensure @start methods emit MethodExecutionStartedEvent (#2114)
Previously, `@start` methods triggered a `FlowStartedEvent` but did not
emit a `MethodExecutionStartedEvent`. This was fine for a single entry
point but caused ambiguity when multiple `@start` methods existed.

This commit (1) emits events for starting points, (2) adds tests
ensuring ordering, (3) adds more fields to events.

90b3145e92 Updated excel_knowledge_source.py to account for excel files with multiple tabs. (#1921)
* Updated excel_knowledge_source.py to account for excel sheets that have multiple tabs. The old implementation contained a single df=pd.read_excel(excel_file_path), which only reads the first or most recently used excel sheet. The updated functionality reads all sheets in the excel workbook.

* updated load_content() function in excel_knowledge_source.py to reduce memory usage and provide better documentation

* accidentally didn't delete the old load_content() function in last commit - corrected this

* Added an override for the content field from the inheritted BaseFileKnowledgeSource to account for the change in the load_content method to support excel files with multiple tabs/sheets. This change should ensure it passes the type check test, as it failed before since content was assigned a different type in BaseFileKnowledgeSource

* Now removed the commented out imports in _import_dependencies, as requested

* Updated excel_knowledge_source to fix linter errors and type errors. Changed inheritence from basefileknowledgesource to baseknowledgesource because basefileknowledgesource's types conflicted (in particular the load_content function and the content class variable.

515478473a Fix : short_term_memory with bedrock - using user defined model(when passed as attribute) rather than default (#1959)

Modified  _configure_bedrock method to use user submitted model_name rather than default  amazon.titan-embed-text-v1.

Sending model_name in short_term_memory (embedder_config/config) was not working.


 # Passing model_name to use model_name provide by user than using default. Added if/else for backward compatibility

* Update embedding_configurator.py

### 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.
- 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

description: 'Tap into CrewAI events to build custom integrations and monitoring'

# Event Listeners
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.
![Prompt Tracing Dashboard](../images/enterprise/prompt-tracing.png)
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
CrewAI provides a wide range of events that you can listen for:
### Crew Events
- **CrewKickoffStartedEvent**: Emitted when a Crew starts execution
- **CrewKickoffCompletedEvent**: Emitted when a Crew completes execution
- **CrewKickoffFailedEvent**: Emitted when a Crew fails to complete execution
- **CrewTestStartedEvent**: Emitted when a Crew starts testing
- **CrewTestCompletedEvent**: Emitted when a Crew completes testing
- **CrewTestFailedEvent**: Emitted when a Crew fails to complete testing
- **CrewTrainStartedEvent**: Emitted when a Crew starts training
- **CrewTrainCompletedEvent**: Emitted when a Crew completes training
- **CrewTrainFailedEvent**: Emitted when a Crew fails to complete training
### Agent Events
- **AgentExecutionStartedEvent**: Emitted when an Agent starts executing a task
- **AgentExecutionCompletedEvent**: Emitted when an Agent completes executing a task
- **AgentExecutionErrorEvent**: Emitted when an Agent encounters an error during execution
### Task Events
- **TaskStartedEvent**: Emitted when a Task starts execution
- **TaskCompletedEvent**: Emitted when a Task completes execution
- **TaskFailedEvent**: Emitted when a Task fails to complete execution
- **TaskEvaluationEvent**: Emitted when a Task is evaluated
### Tool Usage Events
- **ToolUsageStartedEvent**: Emitted when a tool execution is started
- **ToolUsageFinishedEvent**: Emitted when a tool execution is completed
- **ToolUsageErrorEvent**: Emitted when a tool execution encounters an error
- **ToolValidateInputErrorEvent**: Emitted when a tool input validation encounters an error
- **ToolExecutionErrorEvent**: Emitted when a tool execution encounters an error
- **ToolSelectionErrorEvent**: Emitted when there's an error selecting a tool
### Flow Events
- **FlowCreatedEvent**: Emitted when a Flow is created
- **FlowStartedEvent**: Emitted when a Flow starts execution
- **FlowFinishedEvent**: Emitted when a Flow completes execution
- **FlowPlotEvent**: Emitted when a Flow is plotted
- **MethodExecutionStartedEvent**: Emitted when a Flow method starts execution
- **MethodExecutionFinishedEvent**: Emitted when a Flow method completes execution
- **MethodExecutionFailedEvent**: Emitted when a Flow method fails to complete execution
### LLM Events
- **LLMCallStartedEvent**: Emitted when an LLM call starts
- **LLMCallCompletedEvent**: Emitted when an LLM call completes
- **LLMCallFailedEvent**: Emitted when an LLM call fails
- **LLMStreamChunkEvent**: Emitted for each chunk received during streaming LLM responses
## 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.

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.

## Adding Agents to Flows
Agents can be seamlessly integrated into your flows, providing a lightweight alternative to full Crews when you need simpler, focused task execution. Here's an example of how to use an Agent within a flow to perform market research:
```python
import asyncio
from typing import Any, Dict, List
from crewai_tools import SerperDevTool
from pydantic import BaseModel, Field
from crewai.agent import Agent
from crewai.flow.flow import Flow, listen, start
# Define a structured output format
class MarketAnalysis(BaseModel):
key_trends: List[str] = Field(description="List of identified market trends")
market_size: str = Field(description="Estimated market size")
competitors: List[str] = Field(description="Major competitors in the space")
# Define flow state
class MarketResearchState(BaseModel):
product: str = ""
analysis: MarketAnalysis | None = None
# Create a flow class
class MarketResearchFlow(Flow[MarketResearchState]):
@start()
def initialize_research(self) -> Dict[str, Any]:
print(f"Starting market research for {self.state.product}")
return {"product": self.state.product}
@listen(initialize_research)
async def analyze_market(self) -> Dict[str, Any]:
# Create an Agent for market research
analyst = Agent(
role="Market Research Analyst",
goal=f"Analyze the market for {self.state.product}",
backstory="You are an experienced market analyst with expertise in "
"identifying market trends and opportunities.",
tools=[SerperDevTool()],
verbose=True,
)
# Define the research query
query = f"""
Research the market for {self.state.product}. Include:
1. Key market trends
2. Market size
3. Major competitors
Format your response according to the specified structure.
"""
# Execute the analysis with structured output format
result = await analyst.kickoff_async(query, response_format=MarketAnalysis)
if result.pydantic:
print("result", result.pydantic)
else:
print("result", result)
# Return the analysis to update the state
return {"analysis": result.pydantic}
@listen(analyze_market)
def present_results(self, analysis) -> None:
print("\nMarket Analysis Results")
print("=====================")
if isinstance(analysis, dict):
# If we got a dict with 'analysis' key, extract the actual analysis object
market_analysis = analysis.get("analysis")
else:
market_analysis = analysis
if market_analysis and isinstance(market_analysis, MarketAnalysis):
print("\nKey Market Trends:")
for trend in market_analysis.key_trends:
print(f"- {trend}")
print(f"\nMarket Size: {market_analysis.market_size}")
print("\nMajor Competitors:")
for competitor in market_analysis.competitors:
print(f"- {competitor}")
else:
print("No structured analysis data available.")
print("Raw analysis:", analysis)
# Usage example
async def run_flow():
flow = MarketResearchFlow()
result = await flow.kickoff_async(inputs={"product": "AI-powered chatbots"})
return result
# Run the flow
if __name__ == "__main__":
asyncio.run(run_flow())
```
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.

## Security Considerations
When configuring memory storage:
- Use environment variables for storage paths (e.g., `CREWAI_STORAGE_DIR`)
- Never hardcode sensitive information like database credentials
- Consider access permissions for storage directories
- Use relative paths when possible to maintain portability
Example using environment variables:
```python
import os
from crewai import Crew
from crewai.memory import LongTermMemory
from crewai.memory.storage.ltm_sqlite_storage import LTMSQLiteStorage
# Configure storage path using environment variable
storage_path = os.getenv("CREWAI_STORAGE_DIR", "./storage")
crew = Crew(
memory=True,
long_term_memory=LongTermMemory(
storage=LTMSQLiteStorage(
db_path="{storage_path}/memory.db".format(storage_path=storage_path)
)
)
)
```
## Configuration Examples
### Basic Memory Configuration
```python
from crewai import Crew
from crewai.memory import LongTermMemory
# Simple memory configuration
crew = Crew(memory=True) # Uses default storage locations
```
Note that External Memory wont be defined when `memory=True` is set, as we cant infer which external memory would be suitable for your case
### Custom Storage Configuration
```python
from crewai import Crew
from crewai.memory import LongTermMemory
from crewai.memory.storage.ltm_sqlite_storage import LTMSQLiteStorage
# Configure custom storage paths
crew = Crew(
memory=True,
long_term_memory=LongTermMemory(
storage=LTMSQLiteStorage(db_path="./memory.db")
)

### Using Local Mem0 memory
If you want to use local mem0 memory, with a custom configuration, you can set a parameter `local_mem0_config` in the config itself.
If both os environment key is set and local_mem0_config is given, the API platform takes higher priority over the local configuration.

### Using External Memory
External Memory is a powerful feature that allows you to integrate external memory systems with your CrewAI applications. This is particularly useful when you want to use specialized memory providers or maintain memory across different applications.
Since its an external memory, were not able to add a default value to it - unlike with Long Term and Short Term memory.

#### Using External Memory with Custom Storage
You can also create custom storage implementations for External Memory. Here's an example of how to create a custom storage:
```python
from crewai import Agent, Crew, Process, Task
from crewai.memory.external.external_memory import ExternalMemory
from crewai.memory.storage.interface import Storage
class CustomStorage(Storage):
def __init__(self):
self.memories = []
def save(self, value, metadata=None, agent=None):
self.memories.append({"value": value, "metadata": metadata, "agent": agent})
def search(self, query, limit=10, score_threshold=0.5):
# Implement your search logic here
return []
def reset(self):
self.memories = []
# Create external memory with custom storage
external_memory = ExternalMemory(
storage=CustomStorage(),
embedder_config={"provider": "mem0", "config": {"user_id": "U-123"}},
)
agent = Agent(

title: Tool Repository
description: "Using the Tool Repository to manage your tools"
icon: "toolbox"
---
## Overview
The Tool Repository is a package manager for CrewAI tools. It allows users to publish, install, and manage tools that integrate with CrewAI crews and flows.
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
- [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:
`CrewAI Enterprise > Tools > Your Tool > Versions`

title: Traces
description: "Using Traces to monitor your Crews"
icon: "timeline"
---
## 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
<Frame>
![Traces Overview](/images/enterprise/traces-overview.png)
</Frame>
## Accessing Traces
<Steps>
<Step title="Navigate to the Traces Tab">
Once in your CrewAI Enterprise dashboard, click on the **Traces** to view all execution records.
</Step>
<Step title="Select an Execution">
You'll see a list of all crew executions, sorted by date. Click on any execution to view its detailed trace.
</Step>
</Steps>
## 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>
![Execution Summary](/images/enterprise/trace-summary.png)
</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>
![Task List](/images/enterprise/trace-tasks.png)
</Frame>
### 3. Final Output
Displays the final result produced by the crew after all tasks are completed.
<Frame>
![Final Output](/images/enterprise/final-output.png)
</Frame>
### 4. Execution Timeline
A visual representation of when each task started and ended, helping you identify bottlenecks or parallel execution patterns.
<Frame>
![Execution Timeline](/images/enterprise/trace-timeline.png)
</Frame>
### 5. Detailed Task View
When you click on a specific task in the timeline or task list, you'll see:
<Frame>
![Detailed Task View](/images/enterprise/trace-detailed-task.png)
</Frame>
- **Task Key**: Unique identifier for the task
- **Task ID**: Technical identifier in the system
- **Status**: Current state (completed/running/failed)
- **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>
![Failure Points](/images/enterprise/failure.png)
</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
</Step>
</Steps>

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.

description: "Deploy your local CrewAI project to the Enterprise platform"
icon: "cloud-arrow-up"
---
## Option 1: CLI Deployment
<Tip>
This video tutorial walks you through the process of deploying your locally developed CrewAI project to the CrewAI Enterprise platform,
transforming it into a production-ready API endpoint.
</Tip>
<iframe
width="100%"
height="400"
src="https://www.youtube.com/embed/3EqSV-CYDZA"
title="Deploying a Crew to CrewAI Enterprise"
frameborder="0"
style={{ borderRadius: '10px' }}
allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
allowfullscreen
></iframe>
## Prerequisites
Before starting the deployment process, make sure you have:
- A CrewAI project built locally ([follow our quickstart guide](/quickstart) if you haven't created one yet)
- Your code pushed to a GitHub repository
- The latest version of the CrewAI CLI installed (`uv tool install crewai`)
<Note>
For a quick reference project, you can clone our example repository at [github.com/tonykipkemboi/crewai-latest-ai-development](https://github.com/tonykipkemboi/crewai-latest-ai-development).
</Note>
### Step 1: 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 2: 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 3: 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>
### 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
crewai deploy status
# View the logs of your deployment
crewai deploy logs
# Push updates after code changes
crewai deploy push
# Remove a deployment
crewai deploy remove <deployment_id>
```
## 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.
### Step 1: Pushing to GitHub
First, 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 2: Connecting GitHub to CrewAI Enterprise
1. Log in to [CrewAI Enterprise](https://app.crewai.com)
2. Click on the button "Connect GitHub"
<Frame>
![Connect GitHub Button](/images/enterprise/connect-github.png)
</Frame>
### Step 3: Select the Repository
After connecting your GitHub account, you'll be able to select which repository to deploy:
<Frame>
![Select Repository](/images/enterprise/select-repo.png)
</Frame>
### Step 4: 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>
![Set Environment Variables](/images/enterprise/set-env-variables.png)
</Frame>
### Step 5: 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>
![Deploy Progress](/images/enterprise/deploy-progress.png)
</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
### 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

# Kickoff a Crew on CrewAI Enterprise
Once you've deployed your crew to the CrewAI Enterprise platform, you can kickoff executions through the web interface or the API. This guide covers both approaches.
## Method 1: Using the Web Interface
### Step 1: Navigate to Your Deployed Crew
1. Log in to [CrewAI Enterprise](https://app.crewai.com)
2. Click on the crew name from your projects list
3. You'll be taken to the crew's detail page
<Frame>
![Crew Dashboard](/images/enterprise/crew-dashboard.png)
</Frame>
### Step 2: Initiate Execution
From your crew's detail page, you have two options to kickoff an execution:
#### Option A: Quick Kickoff
1. Click the `Kickoff` link in the Test Endpoints section
2. Enter the required input parameters for your crew in the JSON editor
3. Click the `Send Request` button
<Frame>
![Kickoff Endpoint](/images/enterprise/kickoff-endpoint.png)
</Frame>
#### Option B: Using the Visual Interface
1. Click the `Run` tab in the crew detail page
2. Enter the required inputs in the form fields
3. Click the `Run Crew` button
<Frame>
![Run Crew](/images/enterprise/run-crew.png)
</Frame>
### 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>
![Copy Task ID](/images/enterprise/copy-task-id.png)
</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>
![Get Status](/images/enterprise/get-status.png)
</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

title: "Update Crew"
description: "Updating a Crew on CrewAI Enterprise"
icon: "pencil"
---
<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>
![Re-deploy Button](/images/enterprise/redeploy-button.png)
</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>
![Reset Token](/images/enterprise/reset-token.png)
</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>
![Environment Variables Button](/images/enterprise/env-vars-button.png)
</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
<Frame>
![Update Environment Variables](/images/enterprise/update-env-vars.png)
</Frame>
5. Finally, click the `Update Deployment` button at the bottom of the page to apply the changes
<Note>
Updating environment variables will trigger a new deployment, but this will only update the environment configuration and not the code itself.
</Note>
## After Updating
After performing any update:
1. The system will rebuild and redeploy your crew
2. You can monitor the deployment progress in real-time
3. Once complete, test your crew to ensure the changes are working as expected
<Tip>
If you encounter any issues after updating, you can view deployment logs in the platform or contact support for assistance.

title: "Trigger Deployed Crew API"
description: "Using your deployed crew's API on CrewAI Enterprise"
icon: "arrow-up-right-from-square"
---
Once you have deployed your crew to CrewAI Enterprise, it automatically becomes available as a REST API. This guide explains how to interact with your crew programmatically.
## API Basics
Your deployed crew exposes several endpoints that allow you to:
1. Discover required inputs
2. Start crew executions
3. Monitor execution status
4. Receive results
### Authentication
All API requests require a bearer token for authentication, which is generated when you deploy your crew:
```bash
curl -H "Authorization: Bearer YOUR_CREW_TOKEN" https://your-crew-url.crewai.com/...
```
<Tip>
You can find your bearer token in the Status tab of your crew's detail page in the CrewAI Enterprise dashboard.
</Tip>
<Frame>
![Bearer Token](/images/enterprise/bearer-token.png)
</Frame>
## Available Endpoints
Your crew API provides three main endpoints:
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/inputs` | GET | Lists all required inputs for crew execution |
| `/kickoff` | POST | Starts a crew execution with provided inputs |
| `/status/{kickoff_id}` | GET | Retrieves the status and results of an execution |
## GET /inputs
The inputs endpoint allows you to discover what parameters your crew requires:
```bash
curl -X GET \
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
https://your-crew-url.crewai.com/inputs
```
### Response
```json
{
"inputs": ["budget", "interests", "duration", "age"]
}
```
This response indicates that your crew expects four input parameters: `budget`, `interests`, `duration`, and `age`.
## POST /kickoff
The kickoff endpoint starts a new crew execution:
```bash
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
-d '{
"inputs": {
"budget": "1000 USD",
"interests": "games, tech, ai, relaxing hikes, amazing food",
"duration": "7 days",
"age": "35"
}
}' \
https://your-crew-url.crewai.com/kickoff
```
### Request Parameters
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `inputs` | Object | Yes | Key-value pairs of all required inputs |
| `meta` | Object | No | Additional metadata to pass to the crew |
| `taskWebhookUrl` | String | No | Callback URL executed after each task |
| `stepWebhookUrl` | String | No | Callback URL executed after each agent thought |
| `crewWebhookUrl` | String | No | Callback URL executed when the crew finishes |
### Example with Webhooks
```json
{
"inputs": {
"budget": "1000 USD",
"interests": "games, tech, ai, relaxing hikes, amazing food",
"duration": "7 days",
"age": "35"
},
"meta": {
"requestId": "user-request-12345",
"source": "mobile-app"
},
"taskWebhookUrl": "https://your-server.com/webhooks/task",
"stepWebhookUrl": "https://your-server.com/webhooks/step",
"crewWebhookUrl": "https://your-server.com/webhooks/crew"
}
```
### Response
```json
{
"kickoff_id": "abcd1234-5678-90ef-ghij-klmnopqrstuv"
}
```
The `kickoff_id` is used to track and retrieve the execution results.
## GET /status/{kickoff_id}
The status endpoint allows you to check the progress and results of a crew execution:
```bash
curl -X GET \
-H "Authorization: Bearer YOUR_CREW_TOKEN" \
https://your-crew-url.crewai.com/status/abcd1234-5678-90ef-ghij-klmnopqrstuv
```
### Response Structure
The response structure will vary depending on the execution state:
#### In Progress
```json
{
"status": "running",
"current_task": "research_task",
"progress": {
"completed_tasks": 0,
"total_tasks": 2
}
}
```
#### Completed
```json
{
"status": "completed",
"result": {
"output": "Comprehensive travel itinerary...",
"tasks": [
{
"task_id": "research_task",
"output": "Research findings...",
"agent": "Researcher",
"execution_time": 45.2
},
{
"task_id": "planning_task",
"output": "7-day itinerary plan...",
"agent": "Trip Planner",
"execution_time": 62.8
}
]
},
"execution_time": 108.5
}
```
## Webhook Integration
When you provide webhook URLs in your kickoff request, the system will make POST requests to those URLs at specific points in the execution:
### taskWebhookUrl
Called when each task completes:
```json
{
"kickoff_id": "abcd1234-5678-90ef-ghij-klmnopqrstuv",
"task_id": "research_task",
"status": "completed",
"output": "Research findings...",
"agent": "Researcher",
"execution_time": 45.2
}
```
### stepWebhookUrl
Called after each agent thought or action:
```json
{
"kickoff_id": "abcd1234-5678-90ef-ghij-klmnopqrstuv",
"task_id": "research_task",
"agent": "Researcher",
"step_type": "thought",
"content": "I should first search for popular destinations that match these interests..."
}
```
### crewWebhookUrl
Called when the entire crew execution completes:
```json
{
"kickoff_id": "abcd1234-5678-90ef-ghij-klmnopqrstuv",
"status": "completed",
"result": {
"output": "Comprehensive travel itinerary...",
"tasks": [
{
"task_id": "research_task",
"output": "Research findings...",
"agent": "Researcher",
"execution_time": 45.2
},
{
"task_id": "planning_task",
"output": "7-day itinerary plan...",
"agent": "Trip Planner",
"execution_time": 62.8
}
]
},
"execution_time": 108.5,
"meta": {
"requestId": "user-request-12345",
"source": "mobile-app"
}
}
```
## Best Practices
### Handling Long-Running Executions
Crew executions can take anywhere from seconds to minutes depending on their complexity. Consider these approaches:
1. **Webhooks (Recommended)**: Set up webhook endpoints to receive notifications when the execution completes
2. **Polling**: Implement a polling mechanism with exponential backoff
3. **Client-Side Timeout**: Set appropriate timeouts for your API requests
### Error Handling
The API may return various error codes:
| Code | Description | Recommended Action |
|------|-------------|-------------------|
| 401 | Unauthorized | Check your bearer token |
| 404 | Not Found | Verify your crew URL and kickoff_id |
| 422 | Validation Error | Ensure all required inputs are provided |
| 500 | Server Error | Contact support with the error details |
### Sample Code
Here's a complete Python example for interacting with your crew API:
```python
import requests
import time
# Configuration
CREW_URL = "https://your-crew-url.crewai.com"
BEARER_TOKEN = "your-crew-token"
HEADERS = {
"Authorization": f"Bearer {BEARER_TOKEN}",
"Content-Type": "application/json"
}
# 1. Get required inputs
response = requests.get(f"{CREW_URL}/inputs", headers=HEADERS)
required_inputs = response.json()["inputs"]
print(f"Required inputs: {required_inputs}")
# 2. Start crew execution
payload = {
"inputs": {
"budget": "1000 USD",
"interests": "games, tech, ai, relaxing hikes, amazing food",
"duration": "7 days",
"age": "35"
}
}
response = requests.post(f"{CREW_URL}/kickoff", headers=HEADERS, json=payload)
kickoff_id = response.json()["kickoff_id"]
print(f"Execution started with ID: {kickoff_id}")
# 3. Poll for results
MAX_RETRIES = 30
POLL_INTERVAL = 10 # seconds
for i in range(MAX_RETRIES):
print(f"Checking status (attempt {i+1}/{MAX_RETRIES})...")
response = requests.get(f"{CREW_URL}/status/{kickoff_id}", headers=HEADERS)
data = response.json()
if data["status"] == "completed":
print("Execution completed!")
print(f"Result: {data['result']['output']}")
break
elif data["status"] == "error":
print(f"Execution failed: {data.get('error', 'Unknown error')}")
break
else:
print(f"Status: {data['status']}, waiting {POLL_INTERVAL} seconds...")
time.sleep(POLL_INTERVAL)
```

title: FAQs
description: "Frequently asked questions about CrewAI Enterprise"
icon: "code"
---
<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 Suited 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, allowing for efficient resource utilization.
- **Structured validation and oversight**: Manager agent reviews task outputs and ensures task completion, increasing reliability and accuracy.
- **Complex task management**: Assigning tools at the agent level allows for precise control over tool availability, facilitating the execution of intricate tasks.
</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?">
It 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.
</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 to tailor and enhance agent behavior and capabilities:
- **Language Model Customization**: Agents can be customized with specific language models (`llm`) and function-calling language models (`function_calling_llm`), offering advanced control over their processing and decision-making abilities.
- **Performance and Debugging Settings**: Adjust an agent's performance and monitor its operations for efficient task execution.
- **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 for Task Execution**: The `max_iter` attribute allows users to define the maximum number of iterations an agent can perform for a single task, preventing infinite loops or excessively long executions.
- **Delegation and Autonomy**: Control an agent's ability to delegate or ask questions, tailoring its autonomy and collaborative dynamics within the CrewAI framework. By default, the `allow_delegation` attribute is set to True, enabling agents to seek assistance or delegate tasks as needed. This default behavior promotes collaborative problem-solving and efficiency within the CrewAI ecosystem. If needed, delegation can be disabled to suit specific operational requirements.
- **Human Input in Agent Execution**: Human input is critical in several agent execution scenarios, allowing agents to request additional information or clarification when necessary. This feature is especially useful in complex decision-making processes or when agents require more details to complete a task effectively.
</Accordion>
<Accordion title="In what scenarios is human input particularly useful in agent execution?">
Human input is particularly useful in agent execution when:
- **Agents require additional information or clarification**: When agents encounter ambiguity or incomplete data, human input can provide the necessary context to complete the task effectively.
- **Agents need to make complex or sensitive decisions**: Human input can assist agents in ethical or nuanced decision-making, ensuring responsible and informed outcomes.
- **Oversight and validation of agent output**: Human input can help validate the results generated by agents, ensuring accuracy and preventing any misinterpretation or errors.
- **Customizing agent behavior**: Human input can provide feedback on agent responses, allowing users to refine the agent's behavior and responses over time.
- **Identifying and resolving errors or limitations**: Human input can help identify and address any errors or limitations in the agent's capabilities, enabling continuous improvement and optimization.
</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`
- `long-term memory`
- `entity memory`
- `contextual memory`
Learn more about the different types of memory here:
<Card href="https://docs.crewai.com/concepts/memory" icon="brain">CrewAI Memory</Card>
</Accordion>
<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.

</Accordion>
<Accordion title="How do I use Output Pydantic in a Task?">
To use Output Pydantic in a task, you need to define the expected output of the task as a Pydantic model. Here's an example:
<Steps>
<Step title="Define a Pydantic model">
First, you need to define a Pydantic model. For instance, let's create a simple model for a user:
```python
from pydantic import BaseModel
class User(BaseModel):
name: str
age: int
```
</Step>
<Step title="Then, when creating a task, specify the expected output as this Pydantic model:">
```python
from crewai import Task, Crew, Agent
# Import the User model
from my_models import User
# Create a task with Output Pydantic
task = Task(
description="Create a user with the provided name and age",
expected_output=User, # This is the Pydantic model
agent=agent,
tools=[tool1, tool2]
)
```
</Step>
<Step title="In your agent, make sure to set the output_pydantic attribute to the Pydantic model you're using:">
```python
from crewai import Agent
# Import the User model
from my_models import User
# Create an agent with Output Pydantic
agent = Agent(
role='User Creator',
goal='Create users',
backstory='I am skilled in creating user accounts',
tools=[tool1, tool2],
output_pydantic=User
)
```
</Step>
<Step title="When executing the crew, the output of the task will be a User object:">
```python
from crewai import Crew
# Create a crew with the agent and task
crew = Crew(agents=[agent], tasks=[task])
# Kick off the crew
result = crew.kickoff()
# The output of the task will be a User object
print(result.tasks[0].output)
```
</Step>
</Steps>

title: Customizing Prompts
description: Dive deeper into low-level prompt customization for CrewAI, enabling super custom and complex use cases for different models and languages.
icon: message-pen
---
# Customizing Prompts at a Low Level
## 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. Heres 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 agents 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.
## 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 dont have to redefine every prompt. Heres 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 models nuances.
### Example: Llama 3.3 Prompting Template
For instance, when dealing with Metas 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
Heres 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 dont override them.
<Check>
You now have the foundation for advanced prompt customizations in CrewAI. Whether youre adapting for model-specific structures or domain-specific constraints, this low-level approach lets you shape agent interactions in highly specialized ways.

# Fingerprinting in CrewAI
## 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)
uuid_str = fingerprint.uuid_str # e.g., "123e4567-e89b-12d3-a456-426614174000"
# Creation timestamp (auto-generated)
created_at = fingerprint.created_at # A datetime object
# Metadata - for additional information (can be customized)
metadata = fingerprint.metadata # A dictionary, defaults to {}
```

# Crafting Effective Agents
## 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
from typing import List, Dict
# Define structured state
class SupportTicketState(BaseModel):
ticket_id: str = ""
customer_name: str = ""
issue_description: str = ""
category: str = ""
priority: str = "medium"
resolution: str = ""
satisfaction_score: int = 0
class CustomerSupportFlow(Flow[SupportTicketState]):
@start()
def receive_ticket(self):
# In a real app, this might come from an API
self.state.ticket_id = "TKT-12345"
self.state.customer_name = "Alex Johnson"
self.state.issue_description = "Unable to access premium features after payment"
return "Ticket received"
@listen(receive_ticket)
def categorize_ticket(self, _):
# Use a direct LLM call for categorization
from crewai import LLM
llm = LLM(model="openai/gpt-4o-mini")
prompt = f"""
Categorize the following customer support issue into one of these categories:
- Billing
- Account Access
- Technical Issue
- Feature Request
- Other
Issue: {self.state.issue_description}
Return only the category name.
"""
self.state.category = llm.call(prompt).strip()
return self.state.category
@router(categorize_ticket)
def route_by_category(self, category):
# Route to different handlers based on category
return category.lower().replace(" ", "_")
@listen("billing")
def handle_billing_issue(self):
# Handle billing-specific logic
self.state.priority = "high"
# More billing-specific processing...
return "Billing issue handled"
@listen("account_access")
def handle_access_issue(self):
# Handle access-specific logic
self.state.priority = "high"
# More access-specific processing...
return "Access issue handled"
# Additional category handlers...
@listen("billing", "account_access", "technical_issue", "feature_request", "other")
def resolve_ticket(self, resolution_info):
# Final resolution step
self.state.resolution = f"Issue resolved: {resolution_info}"
return self.state.resolution
# 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
# Example: Content Production Pipeline combining Crews and Flows
from crewai.flow.flow import Flow, listen, start
from crewai import Agent, Crew, Process, Task
from pydantic import BaseModel
from typing import List, Dict
class ContentState(BaseModel):
topic: str = ""
target_audience: str = ""

outline_crew = Crew(
agents=[researcher, outliner],
tasks=[research_task, outline_task],
process=Process.sequential,
verbose=True
)
# Run the crew and store the result
result = outline_crew.kickoff()
# Parse the outline (in a real app, you might use a more robust parsing approach)
import json
try:
self.state.outline = json.loads(result.raw)
except:
# Fallback if not valid JSON
self.state.outline = {"sections": result.raw}
return "Outline created"
@listen(create_outline)
def write_content(self, _):
# Use a writing crew to create the content

## 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.

# Build Your First Crew
## 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.
### What You'll Build and Learn
By the end of this guide, you'll have:
1. **Created a specialized AI research team** with distinct roles and responsibilities
2. **Orchestrated collaboration** between multiple AI agents
3. **Automated a complex workflow** that involves gathering information, analysis, and report generation
4. **Built foundational skills** that you can apply to more ambitious projects
While we're building a simple research crew in this guide, the same patterns and techniques can be applied to create much more sophisticated teams for tasks like:
- Multi-stage content creation with specialized writers, editors, and fact-checkers
- Complex customer service systems with tiered support agents
- Autonomous business analysts that gather data, create visualizations, and generate insights
- Product development teams that ideate, design, and plan implementation
Let's get started building your first crew!
### Prerequisites
Before starting, make sure you have:
1. Installed CrewAI following the [installation guide](/installation)
2. Set up your OpenAI API key in your environment variables
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
<Frame caption="CrewAI Framework Overview">
<img src="../../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:
```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: openai/gpt-4o-mini
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: openai/gpt-4o-mini
```
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:
```
OPENAI_API_KEY=your_openai_api_key
SERPER_API_KEY=your_serper_api_key
```
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

# Build Your First Flow
## 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 OpenAI API key in your environment variables
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="../../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:
```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: openai/gpt-4o-mini
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: openai/gpt-4o-mini
```
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
class GuideCreatorState(BaseModel):
topic: str = ""
audience_level: str = ""
guide_outline: GuideOutline = None
sections_content: Dict[str, str] = {}
class GuideCreatorFlow(Flow[GuideCreatorState]):
"""Flow for creating a comprehensive guide on any topic"""
@start()
def get_user_input(self):
"""Get input from the user about the guide topic and audience"""
print("\n=== Create Your Comprehensive Guide ===\n")
# Get user input
self.state.topic = input("What topic would you like to create a guide for? ")
# 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

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:
```
OPENAI_API_KEY=your_openai_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="openai/gpt-4o-mini", 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.

# Mastering Flow State Management
## Understanding the Power of State in Flows
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, persist, start
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, persist, start
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"))
```

# Arize Phoenix Integration
This guide demonstrates how to integrate **Arize Phoenix** with **CrewAI** using OpenTelemetry via the [OpenInference](https://github.com/openinference/openinference) SDK. By the end of this guide, you will be able to trace your CrewAI agents and easily debug your agents.
> **What is Arize Phoenix?** [Arize Phoenix](https://phoenix.arize.com) is an LLM observability platform that provides tracing and evaluation for AI applications.
[![Watch a Video Demo of Our Integration with Phoenix](https://storage.googleapis.com/arize-assets/fixtures/setup_crewai.png)](https://www.youtube.com/watch?v=Yc5q3l6F7Ww)
## Get Started
We'll walk through a simple example of using CrewAI and integrating it with Arize Phoenix via OpenTelemetry using OpenInference.
You can also access this guide on [Google Colab](https://colab.research.google.com/github/Arize-ai/phoenix/blob/main/tutorials/tracing/crewai_tracing_tutorial.ipynb).
### Step 1: Install Dependencies
```bash
pip install openinference-instrumentation-crewai crewai crewai-tools arize-phoenix-otel
```
### Step 2: Set Up Environment Variables
Setup Phoenix Cloud API keys and configure OpenTelemetry to send traces to Phoenix. Phoenix Cloud is a hosted version of Arize Phoenix, but it is not required to use this integration.
You can get your free Serper API key [here](https://serper.dev/).
```python
import os
from getpass import getpass
# Get your Phoenix Cloud credentials
PHOENIX_API_KEY = getpass("🔑 Enter your Phoenix Cloud API Key: ")
# Get API keys for services
OPENAI_API_KEY = getpass("🔑 Enter your OpenAI API key: ")
SERPER_API_KEY = getpass("🔑 Enter your Serper API key: ")
# Set environment variables
os.environ["PHOENIX_CLIENT_HEADERS"] = f"api_key={PHOENIX_API_KEY}"
os.environ["PHOENIX_COLLECTOR_ENDPOINT"] = "https://app.phoenix.arize.com" # Phoenix Cloud, change this to your own endpoint if you are using a self-hosted instance
os.environ["OPENAI_API_KEY"] = OPENAI_API_KEY
os.environ["SERPER_API_KEY"] = SERPER_API_KEY
```
### Step 3: Initialize OpenTelemetry with Phoenix
Initialize the OpenInference OpenTelemetry instrumentation SDK to start capturing traces and send them to Phoenix.
```python
from phoenix.otel import register
tracer_provider = register(
project_name="crewai-tracing-demo",
auto_instrument=True,
)
```
### Step 4: Create a CrewAI Application
We'll create a CrewAI application where two agents collaborate to research and write a blog post about AI advancements.
```python
from crewai import Agent, Crew, Process, Task
from crewai_tools import SerperDevTool
search_tool = SerperDevTool()
# Define your agents with roles and goals
researcher = Agent(
role="Senior Research Analyst",
goal="Uncover cutting-edge developments in AI and data science",
backstory="""You work at a leading tech think tank.
Your expertise lies in identifying emerging trends.
You have a knack for dissecting complex data and presenting actionable insights.""",
verbose=True,
allow_delegation=False,
# You can pass an optional llm attribute specifying what model you wanna use.
# llm=ChatOpenAI(model_name="gpt-3.5", temperature=0.7),
tools=[search_tool],
)
writer = Agent(
role="Tech Content Strategist",
goal="Craft compelling content on tech advancements",
backstory="""You are a renowned Content Strategist, known for your insightful and engaging articles.
You transform complex concepts into compelling narratives.""",
verbose=True,
allow_delegation=True,
)
# Create tasks for your agents
task1 = Task(
description="""Conduct a comprehensive analysis of the latest advancements in AI in 2024.
Identify key trends, breakthrough technologies, and potential industry impacts.""",
expected_output="Full analysis report in bullet points",
agent=researcher,
)
task2 = Task(
description="""Using the insights provided, develop an engaging blog
post that highlights the most significant AI advancements.
Your post should be informative yet accessible, catering to a tech-savvy audience.
Make it sound cool, avoid complex words so it doesn't sound like AI.""",
expected_output="Full blog post of at least 4 paragraphs",
agent=writer,
)
# Instantiate your crew with a sequential process
crew = Crew(
agents=[researcher, writer], tasks=[task1, task2], verbose=1, process=Process.sequential
)
# Get your crew to work!
result = crew.kickoff()
print("######################")
print(result)
```
### Step 5: View Traces in Phoenix
After running the agent, you can view the traces generated by your CrewAI application in Phoenix. You should see detailed steps of the agent interactions and LLM calls, which can help you debug and optimize your AI agents.
Log into your Phoenix Cloud account and navigate to the project you specified in the `project_name` parameter. You'll see a timeline view of your trace with all the agent interactions, tool usages, and LLM calls.

title: Bring your own agent
description: Learn how to bring your own agents that work within a Crew.
icon: robots
---
Interoperability is a core concept in CrewAI. This guide will show you how to bring your own agents that work within a Crew.
## Adapter Guide for Bringing your own agents (Langgraph Agents, OpenAI Agents, etc...)
We require 3 adapters to turn any agent from different frameworks to work within crew.
1. BaseAgentAdapter
2. BaseToolAdapter
3. BaseConverter
## BaseAgentAdapter
This abstract class defines the common interface and functionality that all
agent adapters must implement. It extends BaseAgent to maintain compatibility
with the CrewAI framework while adding adapter-specific requirements.
Required Methods:
1. `def configure_tools`
2. `def configure_structured_output`
## Creating your own Adapter
To integrate an agent from a different framework (e.g., LangGraph, Autogen, OpenAI Assistants) into CrewAI, you need to create a custom adapter by inheriting from `BaseAgentAdapter`. This adapter acts as a compatibility layer, translating between the CrewAI interfaces and the specific requirements of your external agent.
Here's how you implement your custom adapter:
1. **Inherit from `BaseAgentAdapter`**:
```python
from crewai.agents.agent_adapters.base_agent_adapter import BaseAgentAdapter
from crewai.tools import BaseTool
from typing import List, Optional, Any, Dict
class MyCustomAgentAdapter(BaseAgentAdapter):
# ... implementation details ...
```
2. **Implement `__init__`**:
The constructor should call the parent class constructor `super().__init__(**kwargs)` and perform any initialization specific to your external agent. You can use the optional `agent_config` dictionary passed during CrewAI's `Agent` initialization to configure your adapter and the underlying agent.
```python
def __init__(self, agent_config: Optional[Dict[str, Any]] = None, **kwargs: Any):
super().__init__(agent_config=agent_config, **kwargs)
# Initialize your external agent here, possibly using agent_config
# Example: self.external_agent = initialize_my_agent(agent_config)
print(f"Initializing MyCustomAgentAdapter with config: {agent_config}")
```
3. **Implement `configure_tools`**:
This abstract method is crucial. It receives a list of CrewAI `BaseTool` instances. Your implementation must convert or adapt these tools into the format expected by your external agent framework. This might involve wrapping them, extracting specific attributes, or registering them with the external agent instance.
```python
def configure_tools(self, tools: Optional[List[BaseTool]] = None) -> None:
if tools:
adapted_tools = []
for tool in tools:
# Adapt CrewAI BaseTool to the format your agent expects
# Example: adapted_tool = adapt_to_my_framework(tool)
# adapted_tools.append(adapted_tool)
pass # Replace with your actual adaptation logic
# Configure the external agent with the adapted tools
# Example: self.external_agent.set_tools(adapted_tools)
print(f"Configuring tools for MyCustomAgentAdapter: {adapted_tools}") # Placeholder
else:
# Handle the case where no tools are provided
# Example: self.external_agent.set_tools([])
print("No tools provided for MyCustomAgentAdapter.")
```
4. **Implement `configure_structured_output`**:
This method is called when the CrewAI `Agent` is configured with structured output requirements (e.g., `output_json` or `output_pydantic`). Your adapter needs to ensure the external agent is set up to comply with these requirements. This might involve setting specific parameters on the external agent or ensuring its underlying model supports the requested format. If the external agent doesn't support structured output in a way compatible with CrewAI's expectations, you might need to handle the conversion or raise an appropriate error.
```python
def configure_structured_output(self, structured_output: Any) -> None:
# Configure your external agent to produce output in the specified format
# Example: self.external_agent.set_output_format(structured_output)
self.adapted_structured_output = True # Signal that structured output is handled
print(f"Configuring structured output for MyCustomAgentAdapter: {structured_output}")
```
By implementing these methods, your `MyCustomAgentAdapter` will allow your custom agent implementation to function correctly within a CrewAI crew, interacting with tasks and tools seamlessly. Remember to replace the example comments and print statements with your actual adaptation logic specific to the external agent framework you are integrating.
## BaseToolAdapter implementation
The `BaseToolAdapter` class is responsible for converting CrewAI's native `BaseTool` objects into a format that your specific external agent framework can understand and utilize. Different agent frameworks (like LangGraph, OpenAI Assistants, etc.) have their own unique ways of defining and handling tools, and the `BaseToolAdapter` acts as the translator.
Here's how you implement your custom tool adapter:
1. **Inherit from `BaseToolAdapter`**:
```python
from crewai.agents.agent_adapters.base_tool_adapter import BaseToolAdapter
from crewai.tools import BaseTool
from typing import List, Any
class MyCustomToolAdapter(BaseToolAdapter):
# ... implementation details ...
```
2. **Implement `configure_tools`**:
This is the core abstract method you must implement. It receives a list of CrewAI `BaseTool` instances provided to the agent. Your task is to iterate through this list, adapt each `BaseTool` into the format expected by your external framework, and store the converted tools in the `self.converted_tools` list (which is initialized in the base class constructor).
```python
def configure_tools(self, tools: List[BaseTool]) -> None:
"""Configure and convert CrewAI tools for the specific implementation."""
self.converted_tools = [] # Reset in case it's called multiple times
for tool in tools:
# Sanitize the tool name if required by the target framework
sanitized_name = self.sanitize_tool_name(tool.name)
# --- Your Conversion Logic Goes Here ---
# Example: Convert BaseTool to a dictionary format for LangGraph
# converted_tool = {
# "name": sanitized_name,
# "description": tool.description,
# "parameters": tool.args_schema.schema() if tool.args_schema else {},
# # Add any other framework-specific fields
# }
# Example: Convert BaseTool to an OpenAI function definition
# converted_tool = {
# "type": "function",
# "function": {
# "name": sanitized_name,
# "description": tool.description,
# "parameters": tool.args_schema.schema() if tool.args_schema else {"type": "object", "properties": {}},
# }
# }
# --- Replace above examples with your actual adaptation ---
converted_tool = self.adapt_tool_to_my_framework(tool, sanitized_name) # Placeholder
self.converted_tools.append(converted_tool)
print(f"Adapted tool '{tool.name}' to '{sanitized_name}' for MyCustomToolAdapter") # Placeholder
print(f"MyCustomToolAdapter finished configuring tools: {len(self.converted_tools)} adapted.") # Placeholder
# --- Helper method for adaptation (Example) ---
def adapt_tool_to_my_framework(self, tool: BaseTool, sanitized_name: str) -> Any:
# Replace this with the actual logic to convert a CrewAI BaseTool
# to the format needed by your specific external agent framework.
# This will vary greatly depending on the target framework.
adapted_representation = {
"framework_specific_name": sanitized_name,
"framework_specific_description": tool.description,
"inputs": tool.args_schema.schema() if tool.args_schema else None,
"implementation_reference": tool.run # Or however the framework needs to call it
}
# Also ensure the tool works both sync and async
async def async_tool_wrapper(*args, **kwargs):
output = tool.run(*args, **kwargs)
if inspect.isawaitable(output):
return await output
else:
return output
adapted_tool = MyFrameworkTool(
name=sanitized_name,
description=tool.description,
inputs=tool.args_schema.schema() if tool.args_schema else None,
implementation_reference=async_tool_wrapper
)
return adapted_representation
```
3. **Using the Adapter**:
Typically, you would instantiate your `MyCustomToolAdapter` within your `MyCustomAgentAdapter`'s `configure_tools` method and use it to process the tools before configuring your external agent.
```python
# Inside MyCustomAgentAdapter.configure_tools
def configure_tools(self, tools: Optional[List[BaseTool]] = None) -> None:
if tools:
tool_adapter = MyCustomToolAdapter() # Instantiate your tool adapter
tool_adapter.configure_tools(tools) # Convert the tools
adapted_tools = tool_adapter.tools() # Get the converted tools
# Now configure your external agent with the adapted_tools
# Example: self.external_agent.set_tools(adapted_tools)
print(f"Configuring external agent with adapted tools: {adapted_tools}") # Placeholder
else:
# Handle no tools case
print("No tools provided for MyCustomAgentAdapter.")
```
By creating a `BaseToolAdapter`, you decouple the tool conversion logic from the agent adaptation, making the integration cleaner and more modular. Remember to replace the placeholder examples with the actual conversion logic required by your specific external agent framework.
## BaseConverter
The `BaseConverterAdapter` plays a crucial role when a CrewAI `Task` requires an agent to return its final output in a specific structured format, such as JSON or a Pydantic model. It bridges the gap between CrewAI's structured output requirements and the capabilities of your external agent.
Its primary responsibilities are:
1. **Configuring the Agent for Structured Output:** Based on the `Task`'s requirements (`output_json` or `output_pydantic`), it instructs the associated `BaseAgentAdapter` (and indirectly, the external agent) on what format is expected.
2. **Enhancing the System Prompt:** It modifies the agent's system prompt to include clear instructions on *how* to generate the output in the required structure.
3. **Post-processing the Result:** It takes the raw output from the agent and attempts to parse, validate, and format it according to the required structure, ultimately returning a string representation (e.g., a JSON string).
Here's how you implement your custom converter adapter:
1. **Inherit from `BaseConverterAdapter`**:
```python
from crewai.agents.agent_adapters.base_converter_adapter import BaseConverterAdapter
# Assuming you have your MyCustomAgentAdapter defined
# from .my_custom_agent_adapter import MyCustomAgentAdapter
from crewai.task import Task
from typing import Any
class MyCustomConverterAdapter(BaseConverterAdapter):
# Store the expected output type (e.g., 'json', 'pydantic', 'text')
_output_type: str = 'text'
_output_schema: Any = None # Store JSON schema or Pydantic model
# ... implementation details ...
```
2. **Implement `__init__`**:
The constructor must accept the corresponding `agent_adapter` instance it will work with.
```python
def __init__(self, agent_adapter: Any): # Use your specific AgentAdapter type hint
self.agent_adapter = agent_adapter
print(f"Initializing MyCustomConverterAdapter for agent adapter: {type(agent_adapter).__name__}")
```
3. **Implement `configure_structured_output`**:
This method receives the CrewAI `Task` object. You need to check the task's `output_json` and `output_pydantic` attributes to determine the required output structure. Store this information (e.g., in `_output_type` and `_output_schema`) and potentially call configuration methods on your `self.agent_adapter` if the external agent needs specific setup for structured output (which might have been partially handled in the agent adapter's `configure_structured_output` already).
```python
def configure_structured_output(self, task: Task) -> None:
"""Configure the expected structured output based on the task."""
if task.output_pydantic:
self._output_type = 'pydantic'
self._output_schema = task.output_pydantic
print(f"Converter: Configured for Pydantic output: {self._output_schema.__name__}")
elif task.output_json:
self._output_type = 'json'
self._output_schema = task.output_json
print(f"Converter: Configured for JSON output with schema: {self._output_schema}")
else:
self._output_type = 'text'
self._output_schema = None
print("Converter: Configured for standard text output.")
# Optionally, inform the agent adapter if needed
# self.agent_adapter.set_output_mode(self._output_type, self._output_schema)
```
4. **Implement `enhance_system_prompt`**:
This method takes the agent's base system prompt string and should append instructions tailored to the currently configured `_output_type` and `_output_schema`. The goal is to guide the LLM powering the agent to produce output in the correct format.
```python
def enhance_system_prompt(self, base_prompt: str) -> str:
"""Enhance the system prompt with structured output instructions."""
if self._output_type == 'text':
return base_prompt # No enhancement needed for plain text
instructions = "\n\nYour final answer MUST be formatted as "
if self._output_type == 'json':
schema_str = json.dumps(self._output_schema, indent=2)
instructions += f"a JSON object conforming to the following schema:\n```json\n{schema_str}\n```"
elif self._output_type == 'pydantic':
schema_str = json.dumps(self._output_schema.model_json_schema(), indent=2)
instructions += f"a JSON object conforming to the Pydantic model '{self._output_schema.__name__}' with the following schema:\n```json\n{schema_str}\n```"
instructions += "\nEnsure your entire response is ONLY the valid JSON object, without any introductory text, explanations, or concluding remarks."
print(f"Converter: Enhancing prompt for {self._output_type} output.")
return base_prompt + instructions
```
*Note: The exact prompt engineering might need tuning based on the agent/LLM being used.*
5. **Implement `post_process_result`**:
This method receives the raw string output from the agent. If structured output was requested (`json` or `pydantic`), you should attempt to parse the string into the expected format. Handle potential parsing errors (e.g., log them, attempt simple fixes, or raise an exception). Crucially, the method must **always return a string**, even if the intermediate format was a dictionary or Pydantic object (e.g., by serializing it back to a JSON string).
```python
import json
from pydantic import ValidationError
def post_process_result(self, result: str) -> str:
"""Post-process the agent's result to ensure it matches the expected format."""
print(f"Converter: Post-processing result for {self._output_type} output.")
if self._output_type == 'json':
try:
# Attempt to parse and re-serialize to ensure validity and consistent format
parsed_json = json.loads(result)
# Optional: Validate against self._output_schema if it's a JSON schema dictionary
# from jsonschema import validate
# validate(instance=parsed_json, schema=self._output_schema)
return json.dumps(parsed_json)
except json.JSONDecodeError as e:
print(f"Error: Failed to parse JSON output: {e}\nRaw output:\n{result}")
# Handle error: return raw, raise exception, or try to fix
return result # Example: return raw output on failure
# except Exception as e: # Catch validation errors if using jsonschema
# print(f"Error: JSON output failed schema validation: {e}\nRaw output:\n{result}")
# return result
elif self._output_type == 'pydantic':
try:
# Attempt to parse into the Pydantic model
model_instance = self._output_schema.model_validate_json(result)
# Return the model serialized back to JSON
return model_instance.model_dump_json()
except ValidationError as e:
print(f"Error: Failed to validate Pydantic output: {e}\nRaw output:\n{result}")
# Handle error
return result # Example: return raw output on failure
except json.JSONDecodeError as e:
print(f"Error: Failed to parse JSON for Pydantic model: {e}\nRaw output:\n{result}")
return result
else: # 'text'
return result # No processing needed for plain text
```
By implementing these methods, your `MyCustomConverterAdapter` ensures that structured output requests from CrewAI tasks are correctly handled by your integrated external agent, improving the reliability and usability of your custom agent within the CrewAI framework.
## Out of the Box Adapters

title: Custom LLM Implementation
description: Learn how to create custom LLM implementations in CrewAI.
icon: code
---
## Custom LLM Implementations
CrewAI now supports custom LLM implementations through the `BaseLLM` abstract base class. This allows you to create your own LLM implementations that don't rely on litellm's authentication mechanism.
To create a custom LLM implementation, you need to:
1. Inherit from the `BaseLLM` abstract base class
2. Implement the required methods:
- `call()`: The main method to call the LLM with messages
- `supports_function_calling()`: Whether the LLM supports function calling
- `supports_stop_words()`: Whether the LLM supports stop words
- `get_context_window_size()`: The context window size of the LLM
## Example: Basic Custom LLM
```python
from crewai import BaseLLM
from typing import Any, Dict, List, Optional, Union
class CustomLLM(BaseLLM):
def __init__(self, api_key: str, endpoint: str):
super().__init__() # Initialize the base class to set default attributes
if not api_key or not isinstance(api_key, str):
raise ValueError("Invalid API key: must be a non-empty string")
if not endpoint or not isinstance(endpoint, str):
raise ValueError("Invalid endpoint URL: must be a non-empty string")
self.api_key = api_key
self.endpoint = endpoint
self.stop = [] # You can customize stop words if needed
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
"""Call the LLM with the given messages.
Args:
messages: Input messages for the LLM.
tools: Optional list of tool schemas for function calling.
callbacks: Optional list of callback functions.
available_functions: Optional dict mapping function names to callables.
Returns:
Either a text response from the LLM or the result of a tool function call.
Raises:
TimeoutError: If the LLM request times out.
RuntimeError: If the LLM request fails for other reasons.
ValueError: If the response format is invalid.
"""
# Implement your own logic to call the LLM
# For example, using requests:
import requests
try:
headers = {
"Authorization": f"Bearer {self.api_key}",
"Content-Type": "application/json"
}
# Convert string message to proper format if needed
if isinstance(messages, str):
messages = [{"role": "user", "content": messages}]
data = {
"messages": messages,
"tools": tools
}
response = requests.post(
self.endpoint,
headers=headers,
json=data,
timeout=30 # Set a reasonable timeout
)
response.raise_for_status() # Raise an exception for HTTP errors
return response.json()["choices"][0]["message"]["content"]
except requests.Timeout:
raise TimeoutError("LLM request timed out")
except requests.RequestException as e:
raise RuntimeError(f"LLM request failed: {str(e)}")
except (KeyError, IndexError, ValueError) as e:
raise ValueError(f"Invalid response format: {str(e)}")
def supports_function_calling(self) -> bool:
"""Check if the LLM supports function calling.
Returns:
True if the LLM supports function calling, False otherwise.
"""
# Return True if your LLM supports function calling
return True
def supports_stop_words(self) -> bool:
"""Check if the LLM supports stop words.

"""
# Return True if your LLM supports stop words
return True
def get_context_window_size(self) -> int:
"""Get the context window size of the LLM.
Returns:
The context window size as an integer.
"""
# Return the context window size of your LLM
return 8192
```
## Error Handling Best Practices
When implementing custom LLMs, it's important to handle errors properly to ensure robustness and reliability. Here are some best practices:
### 1. Implement Try-Except Blocks for API Calls
Always wrap API calls in try-except blocks to handle different types of errors:
```python
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
try:
# API call implementation
response = requests.post(
self.endpoint,
headers=self.headers,
json=self.prepare_payload(messages),
timeout=30 # Set a reasonable timeout
)
response.raise_for_status() # Raise an exception for HTTP errors
return response.json()["choices"][0]["message"]["content"]
except requests.Timeout:
raise TimeoutError("LLM request timed out")
except requests.RequestException as e:
raise RuntimeError(f"LLM request failed: {str(e)}")
except (KeyError, IndexError, ValueError) as e:
raise ValueError(f"Invalid response format: {str(e)}")
```
### 2. Implement Retry Logic for Transient Failures
For transient failures like network issues or rate limiting, implement retry logic with exponential backoff:
```python
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
import time
max_retries = 3
retry_delay = 1 # seconds
for attempt in range(max_retries):
try:
response = requests.post(
self.endpoint,
headers=self.headers,
json=self.prepare_payload(messages),
timeout=30
)
response.raise_for_status()
return response.json()["choices"][0]["message"]["content"]
except (requests.Timeout, requests.ConnectionError) as e:
if attempt < max_retries - 1:
time.sleep(retry_delay * (2 ** attempt)) # Exponential backoff
continue
raise TimeoutError(f"LLM request failed after {max_retries} attempts: {str(e)}")
except requests.RequestException as e:
raise RuntimeError(f"LLM request failed: {str(e)}")
```
### 3. Validate Input Parameters
Always validate input parameters to prevent runtime errors:
```python
def __init__(self, api_key: str, endpoint: str):
super().__init__()
if not api_key or not isinstance(api_key, str):
raise ValueError("Invalid API key: must be a non-empty string")
if not endpoint or not isinstance(endpoint, str):
raise ValueError("Invalid endpoint URL: must be a non-empty string")
self.api_key = api_key
self.endpoint = endpoint
```
### 4. Handle Authentication Errors Gracefully
Provide clear error messages for authentication failures:
```python
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
try:
response = requests.post(self.endpoint, headers=self.headers, json=data)
if response.status_code == 401:
raise ValueError("Authentication failed: Invalid API key or token")
elif response.status_code == 403:
raise ValueError("Authorization failed: Insufficient permissions")
response.raise_for_status()
# Process response
except Exception as e:
# Handle error
raise
```
## Example: JWT-based Authentication
For services that use JWT-based authentication instead of API keys, you can implement a custom LLM like this:
```python
from crewai import BaseLLM, Agent, Task
from typing import Any, Dict, List, Optional, Union
class JWTAuthLLM(BaseLLM):
def __init__(self, jwt_token: str, endpoint: str):
super().__init__() # Initialize the base class to set default attributes
if not jwt_token or not isinstance(jwt_token, str):
raise ValueError("Invalid JWT token: must be a non-empty string")
if not endpoint or not isinstance(endpoint, str):
raise ValueError("Invalid endpoint URL: must be a non-empty string")
self.jwt_token = jwt_token
self.endpoint = endpoint
self.stop = [] # You can customize stop words if needed
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
"""Call the LLM with JWT authentication.
Args:
messages: Input messages for the LLM.
tools: Optional list of tool schemas for function calling.
callbacks: Optional list of callback functions.
available_functions: Optional dict mapping function names to callables.
Returns:
Either a text response from the LLM or the result of a tool function call.
Raises:
TimeoutError: If the LLM request times out.
RuntimeError: If the LLM request fails for other reasons.
ValueError: If the response format is invalid.
"""
# Implement your own logic to call the LLM with JWT authentication
import requests
try:
headers = {
"Authorization": f"Bearer {self.jwt_token}",
"Content-Type": "application/json"
}
# Convert string message to proper format if needed
if isinstance(messages, str):
messages = [{"role": "user", "content": messages}]
data = {
"messages": messages,
"tools": tools
}
response = requests.post(
self.endpoint,
headers=headers,
json=data,
timeout=30 # Set a reasonable timeout
)
if response.status_code == 401:
raise ValueError("Authentication failed: Invalid JWT token")
elif response.status_code == 403:
raise ValueError("Authorization failed: Insufficient permissions")
response.raise_for_status() # Raise an exception for HTTP errors
return response.json()["choices"][0]["message"]["content"]
except requests.Timeout:
raise TimeoutError("LLM request timed out")
except requests.RequestException as e:
raise RuntimeError(f"LLM request failed: {str(e)}")
except (KeyError, IndexError, ValueError) as e:
raise ValueError(f"Invalid response format: {str(e)}")
def supports_function_calling(self) -> bool:
"""Check if the LLM supports function calling.
Returns:
True if the LLM supports function calling, False otherwise.
"""
return True
def supports_stop_words(self) -> bool:
"""Check if the LLM supports stop words.
Returns:
True if the LLM supports stop words, False otherwise.
"""
return True
def get_context_window_size(self) -> int:
"""Get the context window size of the LLM.
Returns:
The context window size as an integer.
"""
return 8192
```
## Troubleshooting
Here are some common issues you might encounter when implementing custom LLMs and how to resolve them:
### 1. Authentication Failures
**Symptoms**: 401 Unauthorized or 403 Forbidden errors
**Solutions**:
- Verify that your API key or JWT token is valid and not expired
- Check that you're using the correct authentication header format
- Ensure that your token has the necessary permissions
### 2. Timeout Issues
**Symptoms**: Requests taking too long or timing out
**Solutions**:
- Implement timeout handling as shown in the examples
- Use retry logic with exponential backoff
- Consider using a more reliable network connection
### 3. Response Parsing Errors
**Symptoms**: KeyError, IndexError, or ValueError when processing responses
**Solutions**:
- Validate the response format before accessing nested fields
- Implement proper error handling for malformed responses
- Check the API documentation for the expected response format
### 4. Rate Limiting
**Symptoms**: 429 Too Many Requests errors
**Solutions**:
- Implement rate limiting in your custom LLM
- Add exponential backoff for retries
- Consider using a token bucket algorithm for more precise rate control
## Advanced Features
### Logging
Adding logging to your custom LLM can help with debugging and monitoring:
```python
import logging
from typing import Any, Dict, List, Optional, Union
class LoggingLLM(BaseLLM):
def __init__(self, api_key: str, endpoint: str):
super().__init__()
self.api_key = api_key
self.endpoint = endpoint
self.logger = logging.getLogger("crewai.llm.custom")
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
self.logger.info(f"Calling LLM with {len(messages) if isinstance(messages, list) else 1} messages")
try:
# API call implementation
response = self._make_api_call(messages, tools)
self.logger.debug(f"LLM response received: {response[:100]}...")
return response
except Exception as e:
self.logger.error(f"LLM call failed: {str(e)}")
raise
```
### Rate Limiting
Implementing rate limiting can help avoid overwhelming the LLM API:
```python
import time
from typing import Any, Dict, List, Optional, Union
class RateLimitedLLM(BaseLLM):
def __init__(
self,
api_key: str,
endpoint: str,
requests_per_minute: int = 60
):
super().__init__()
self.api_key = api_key
self.endpoint = endpoint
self.requests_per_minute = requests_per_minute
self.request_times: List[float] = []
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
self._enforce_rate_limit()
# Record this request time
self.request_times.append(time.time())
# Make the actual API call
return self._make_api_call(messages, tools)
def _enforce_rate_limit(self) -> None:
"""Enforce the rate limit by waiting if necessary."""
now = time.time()
# Remove request times older than 1 minute
self.request_times = [t for t in self.request_times if now - t < 60]
if len(self.request_times) >= self.requests_per_minute:
# Calculate how long to wait
oldest_request = min(self.request_times)
wait_time = 60 - (now - oldest_request)
if wait_time > 0:
time.sleep(wait_time)
```
### Metrics Collection
Collecting metrics can help you monitor your LLM usage:
```python
import time
from typing import Any, Dict, List, Optional, Union
class MetricsCollectingLLM(BaseLLM):
def __init__(self, api_key: str, endpoint: str):
super().__init__()
self.api_key = api_key
self.endpoint = endpoint
self.metrics: Dict[str, Any] = {
"total_calls": 0,
"total_tokens": 0,
"errors": 0,
"latency": []
}
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
start_time = time.time()
self.metrics["total_calls"] += 1
try:
response = self._make_api_call(messages, tools)
# Estimate tokens (simplified)
if isinstance(messages, str):
token_estimate = len(messages) // 4
else:
token_estimate = sum(len(m.get("content", "")) // 4 for m in messages)
self.metrics["total_tokens"] += token_estimate
return response
except Exception as e:
self.metrics["errors"] += 1
raise
finally:
latency = time.time() - start_time
self.metrics["latency"].append(latency)
def get_metrics(self) -> Dict[str, Any]:
"""Return the collected metrics."""
avg_latency = sum(self.metrics["latency"]) / len(self.metrics["latency"]) if self.metrics["latency"] else 0
return {
**self.metrics,
"avg_latency": avg_latency
}
```
## Advanced Usage: Function Calling
If your LLM supports function calling, you can implement the function calling logic in your custom LLM:
```python
import json
from typing import Any, Dict, List, Optional, Union
def call(
self,
messages: Union[str, List[Dict[str, str]]],
tools: Optional[List[dict]] = None,
callbacks: Optional[List[Any]] = None,
available_functions: Optional[Dict[str, Any]] = None,
) -> Union[str, Any]:
import requests
try:
headers = {
"Authorization": f"Bearer {self.jwt_token}",
"Content-Type": "application/json"
}
# Convert string message to proper format if needed
if isinstance(messages, str):
messages = [{"role": "user", "content": messages}]
data = {
"messages": messages,
"tools": tools
}
response = requests.post(
self.endpoint,
headers=headers,
json=data,
timeout=30
)
response.raise_for_status()
response_data = response.json()
# Check if the LLM wants to call a function
if response_data["choices"][0]["message"].get("tool_calls"):
tool_calls = response_data["choices"][0]["message"]["tool_calls"]
# Process each tool call
for tool_call in tool_calls:
function_name = tool_call["function"]["name"]
function_args = json.loads(tool_call["function"]["arguments"])
if available_functions and function_name in available_functions:
function_to_call = available_functions[function_name]
function_response = function_to_call(**function_args)
# Add the function response to the messages
messages.append({
"role": "tool",
"tool_call_id": tool_call["id"],
"name": function_name,
"content": str(function_response)
})
# Call the LLM again with the updated messages
return self.call(messages, tools, callbacks, available_functions)
# Return the text response if no function call
return response_data["choices"][0]["message"]["content"]
except requests.Timeout:
raise TimeoutError("LLM request timed out")
except requests.RequestException as e:
raise RuntimeError(f"LLM request failed: {str(e)}")
except (KeyError, IndexError, ValueError) as e:
raise ValueError(f"Invalid response format: {str(e)}")
```
## Using Your Custom LLM with CrewAI
Once you've implemented your custom LLM, you can use it with CrewAI agents and crews:
```python
from crewai import Agent, Task, Crew
from typing import Dict, Any
# Create your custom LLM instance
jwt_llm = JWTAuthLLM(
jwt_token="your.jwt.token",
endpoint="https://your-llm-endpoint.com/v1/chat/completions"
)
# Use it with an agent
agent = Agent(
role="Research Assistant",
goal="Find information on a topic",
backstory="You are a research assistant tasked with finding information.",
llm=jwt_llm,
)
# Create a task for the agent
task = Task(
description="Research the benefits of exercise",
agent=agent,
expected_output="A summary of the benefits of exercise",
)
# Execute the task
result = agent.execute_task(task)
print(result)
# Or use it with a crew
crew = Crew(
agents=[agent],
tasks=[task],
manager_llm=jwt_llm, # Use your custom LLM for the manager
)
# Run the crew
result = crew.kickoff()
print(result)
```
## Implementing Your Own Authentication Mechanism
The `BaseLLM` class allows you to implement any authentication mechanism you need, not just JWT or API keys. You can use:
- OAuth tokens
- Client certificates
- Custom headers
- Session-based authentication
- Any other authentication method required by your LLM provider
Simply implement the appropriate authentication logic in your custom LLM class.

# Integrate Langfuse with CrewAI
This notebook demonstrates how to integrate **Langfuse** with **CrewAI** using OpenTelemetry via the **OpenLit** SDK. By the end of this notebook, you will be able to trace your CrewAI applications with Langfuse for improved observability and debugging.
> **What is Langfuse?** [Langfuse](https://langfuse.com) is an open-source LLM engineering platform. It provides tracing and monitoring capabilities for LLM applications, helping developers debug, analyze, and optimize their AI systems. Langfuse integrates with various tools and frameworks via native integrations, OpenTelemetry, and APIs/SDKs.
[![Langfuse Overview Video](https://github.com/user-attachments/assets/3926b288-ff61-4b95-8aa1-45d041c70866)](https://langfuse.com/watch-demo)
## Get Started
We'll walk through a simple example of using CrewAI and integrating it with Langfuse via OpenTelemetry using OpenLit.
### Step 1: Install Dependencies
```python
%pip install langfuse openlit crewai crewai_tools
```
### Step 2: Set Up Environment Variables
Set your Langfuse API keys and configure OpenTelemetry export settings to send traces to Langfuse. Please refer to the [Langfuse OpenTelemetry Docs](https://langfuse.com/docs/opentelemetry/get-started) for more information on the Langfuse OpenTelemetry endpoint `/api/public/otel` and authentication.
```python
import os
import base64
LANGFUSE_PUBLIC_KEY="pk-lf-..."
LANGFUSE_SECRET_KEY="sk-lf-..."
LANGFUSE_AUTH=base64.b64encode(f"{LANGFUSE_PUBLIC_KEY}:{LANGFUSE_SECRET_KEY}".encode()).decode()
os.environ["OTEL_EXPORTER_OTLP_ENDPOINT"] = "https://cloud.langfuse.com/api/public/otel" # EU data region
# os.environ["OTEL_EXPORTER_OTLP_ENDPOINT"] = "https://us.cloud.langfuse.com/api/public/otel" # US data region
os.environ["OTEL_EXPORTER_OTLP_HEADERS"] = f"Authorization=Basic {LANGFUSE_AUTH}"
# your openai key
os.environ["OPENAI_API_KEY"] = "sk-..."
```
### Step 3: Initialize OpenLit
Initialize the OpenLit OpenTelemetry instrumentation SDK to start capturing OpenTelemetry traces.
```python
import openlit
openlit.init()
```
### Step 4: Create a Simple CrewAI Application
We'll create a simple CrewAI application where multiple agents collaborate to answer a user's question.
```python
from crewai import Agent, Task, Crew
from crewai_tools import (
WebsiteSearchTool
)
web_rag_tool = WebsiteSearchTool()
writer = Agent(
role="Writer",
goal="You make math engaging and understandable for young children through poetry",
backstory="You're an expert in writing haikus but you know nothing of math.",
tools=[web_rag_tool],
)
task = Task(description=("What is {multiplication}?"),
expected_output=("Compose a haiku that includes the answer."),
agent=writer)
crew = Crew(
agents=[writer],
tasks=[task],
share_crew=False
)
```
### Step 5: See Traces in Langfuse
After running the agent, you can view the traces generated by your CrewAI application in [Langfuse](https://cloud.langfuse.com). You should see detailed steps of the LLM interactions, which can help you debug and optimize your AI agent.

# MLflow Overview
[MLflow](https://mlflow.org/) is an open-source platform to assist machine learning practitioners and teams in handling the complexities of the machine learning process.
It provides a tracing feature that enhances LLM observability in your Generative AI applications by capturing detailed information about the execution of your applications services.
Tracing provides a way to record the inputs, outputs, and metadata associated with each intermediate step of a request, enabling you to easily pinpoint the source of bugs and unexpected behaviors.
![Overview of MLflow crewAI tracing usage](/images/mlflow-tracing.gif)
### Features
- **Tracing Dashboard**: Monitor activities of your crewAI agents with detailed dashboards that include inputs, outputs and metadata of spans.
- **Automated Tracing**: A fully automated integration with crewAI, which can be enabled by running `mlflow.crewai.autolog()`.
- **Manual Trace Instrumentation with minor efforts**: Customize trace instrumentation through MLflow's high-level fluent APIs such as decorators, function wrappers and context managers.
- **OpenTelemetry Compatibility**: MLflow Tracing supports exporting traces to an OpenTelemetry Collector, which can then be used to export traces to various backends such as Jaeger, Zipkin, and AWS X-Ray.
- **Package and Deploy Agents**: Package and deploy your crewAI agents to an inference server with a variety of deployment targets.
- **Securely Host LLMs**: Host multiple LLM from various providers in one unified endpoint through MFflow gateway.
- **Evaluation**: Evaluate your crewAI agents with a wide range of metrics using a convenient API `mlflow.evaluate()`.

# Opik Overview
With [Comet Opik](https://www.comet.com/docs/opik/), debug, evaluate, and monitor your LLM applications, RAG systems, and agentic workflows with comprehensive tracing, automated evaluations, and production-ready dashboards.
<Frame caption="Opik Agent Dashboard">
<img src="/images/opik-crewai-dashboard.png" alt="Opik agent monitoring example with CrewAI" />
</Frame>
Opik provides comprehensive support for every stage of your CrewAI application development:
- **Log Traces and Spans**: Automatically track LLM calls and application logic to debug and analyze development and production systems. Manually or programmatically annotate, view, and compare responses across projects.
- **Evaluate Your LLM Application's Performance**: Evaluate against a custom test set and run built-in evaluation metrics or define your own metrics in the SDK or UI.
- **Test Within Your CI/CD Pipeline**: Establish reliable performance baselines with Opik's LLM unit tests, built on PyTest. Run online evaluations for continuous monitoring in production.
- **Monitor & Analyze Production Data**: Understand your models' performance on unseen data in production and generate datasets for new dev iterations.
## Setup
Comet provides a hosted version of the Opik platform, or you can run the platform locally.
To use the hosted version, simply [create a free Comet account](https://www.comet.com/signup?utm_medium=github&utm_source=crewai_docs) and grab you API Key.
To run the Opik platform locally, see our [installation guide](https://www.comet.com/docs/opik/self-host/overview/) for more information.
For this guide we will use CrewAIs quickstart example.
<Steps>
<Step title="Install required packages">
```shell
pip install crewai crewai-tools opik --upgrade
```
</Step>
<Step title="Configure Opik">
```python
import opik
opik.configure(use_local=False)
```
</Step>
<Step title="Prepare environment">
First, we set up our API keys for our LLM-provider as environment variables:
```python
import os
import getpass
if "OPENAI_API_KEY" not in os.environ:
os.environ["OPENAI_API_KEY"] = getpass.getpass("Enter your OpenAI API key: ")
```
</Step>
<Step title="Using CrewAI">
The first step is to create our project. We will use an example from CrewAIs documentation:
```python
from crewai import Agent, Crew, Task, Process
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,
)
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(
name="Collect Data 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(
name="Market Research 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,
)
```
Now we can import Opiks tracker and run our crew:
```python
from opik.integrations.crewai import track_crewai
track_crewai(project_name="crewai-integration-demo")
my_crew = YourCrewName().crew()
result = my_crew.kickoff()
print(result)
```
After running your CrewAI application, visit the Opik app to view:
- LLM traces, spans, and their metadata
- Agent interactions and task execution flow
- Performance metrics like latency and token usage
- Evaluation metrics (built-in or custom)
</Step>

# Portkey Integration with CrewAI
<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/main/Portkey-CrewAI.png" alt="Portkey CrewAI Header Image" width="70%" />
[Portkey](https://portkey.ai/?utm_source=crewai&utm_medium=crewai&utm_campaign=crewai) is a 2-line upgrade to make your CrewAI agents reliable, cost-efficient, and fast.
Portkey adds 4 core production capabilities to any CrewAI agent:
1. Routing to **200+ LLMs**
2. Making each LLM call more robust
3. Full-stack tracing & cost, performance analytics
4. Real-time guardrails to enforce behavior
## Getting Started
1. **Install Required Packages:**
```bash
pip install -qU crewai portkey-ai
```
2. **Configure the LLM Client:**
To build CrewAI Agents with Portkey, you'll need two keys:
- **Portkey API Key**: Sign up on the [Portkey app](https://app.portkey.ai/?utm_source=crewai&utm_medium=crewai&utm_campaign=crewai) and copy your API key
- **Virtual Key**: Virtual Keys securely manage your LLM API keys in one place. Store your LLM provider API keys securely in Portkey's vault
```python
from crewai import LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
gpt_llm = LLM(
model="gpt-4",
base_url=PORTKEY_GATEWAY_URL,
api_key="dummy", # We are using Virtual key
extra_headers=createHeaders(
api_key="YOUR_PORTKEY_API_KEY",
virtual_key="YOUR_VIRTUAL_KEY", # Enter your Virtual key from Portkey
)
)
```
3. **Create and Run Your First Agent:**
```python
from crewai import Agent, Task, Crew
# Define your agents with roles and goals
coder = Agent(
role='Software developer',
goal='Write clear, concise code on demand',
backstory='An expert coder with a keen eye for software trends.',
llm=gpt_llm
)
# Create tasks for your agents
task1 = Task(
description="Define the HTML for making a simple website with heading- Hello World! Portkey is working!",
expected_output="A clear and concise HTML code",
agent=coder
)
# Instantiate your crew
crew = Crew(
agents=[coder],
tasks=[task1],
)
result = crew.kickoff()
print(result)
```

</Frame>
### 1. Use 250+ LLMs
Access various LLMs like Anthropic, Gemini, Mistral, Azure OpenAI, and more with minimal code changes. Switch between providers or use them together seamlessly. [Learn more about Universal API](https://portkey.ai/docs/product/ai-gateway/universal-api)
Easily switch between different LLM providers:
```python
# Anthropic Configuration
anthropic_llm = LLM(
model="claude-3-5-sonnet-latest",
base_url=PORTKEY_GATEWAY_URL,
api_key="dummy",
extra_headers=createHeaders(
api_key="YOUR_PORTKEY_API_KEY",
virtual_key="YOUR_ANTHROPIC_VIRTUAL_KEY", #You don't need provider when using Virtual keys
trace_id="anthropic_agent"
)
)
# Azure OpenAI Configuration
azure_llm = LLM(
model="gpt-4",
base_url=PORTKEY_GATEWAY_URL,
api_key="dummy",
extra_headers=createHeaders(
api_key="YOUR_PORTKEY_API_KEY",
virtual_key="YOUR_AZURE_VIRTUAL_KEY", #You don't need provider when using Virtual keys
trace_id="azure_agent"
)
)
```
### 2. Caching
Improve response times and reduce costs with two powerful caching modes:
- **Simple Cache**: Perfect for exact matches
- **Semantic Cache**: Matches responses for requests that are semantically similar
[Learn more about Caching](https://portkey.ai/docs/product/ai-gateway/cache-simple-and-semantic)
```py
config = {
"cache": {
"mode": "semantic", # or "simple" for exact matching
}
}
```
### 3. Production Reliability
Portkey provides comprehensive reliability features:
- **Automatic Retries**: Handle temporary failures gracefully

**Python Version Requirements**
CrewAI requires `Python >=3.10 and <3.13`. Here's how to check your version:
```bash
python3 --version
```
If you need to update Python, visit [python.org/downloads](https://python.org/downloads)
</Note>
# Installing CrewAI
CrewAI uses the `uv` as its dependency management and package handling tool. It simplifies project setup and execution, offering a seamless experience.
CrewAI is a flexible and powerful AI framework that enables you to create and manage AI agents, tools, and tasks efficiently.
Let's get you set up! 🚀
If you haven't installed `uv` yet, follow **step 1** to quickly get it set up on your system, else you can skip to **step 2**.
<Steps>
<Step title="Install CrewAI">
Install CrewAI with all recommended tools using either method:
```shell Terminal
pip install 'crewai[tools]'
<Step title="Install uv">
- **On macOS/Linux:**
Use `curl` to download the script and execute it with `sh`:
```shell
curl -LsSf https://astral.sh/uv/install.sh | sh
```
or
```shell Terminal
pip install crewai crewai-tools
If your system doesn't have `curl`, you can use `wget`:
```shell
wget -qO- https://astral.sh/uv/install.sh | sh
```
<Note>
Both methods install the core package and additional tools needed for most use cases.
</Note>
- **On Windows:**
Use `irm` to download the script and `iex` to execute it:
```shell
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```
If you run into any issues, refer to [UV's installation guide](https://docs.astral.sh/uv/getting-started/installation/) for more information.
</Step>
<Step title="Upgrade CrewAI (Existing Installations Only)">
If you have an older version of CrewAI installed, you can upgrade it:
```shell Terminal
pip install --upgrade crewai crewai-tools
<Step title="Install CrewAI 🚀">
- Run the following command to install `crewai` CLI:
```shell
uv tool install crewai
```
<Warning>
If you see a Poetry-related warning, you'll need to migrate to our new dependency manager:
```shell Terminal
crewai update
<Warning>
If you encounter a `PATH` warning, run this command to update your shell:
```shell
uv tool update-shell
```
This will update your project to use [UV](https://github.com/astral-sh/uv), our new faster dependency manager.
</Warning>
</Warning>
<Note>
Skip this step if you're doing a fresh installation.
</Note>
</Step>
<Step title="Verify Installation">
Check your installed versions:
```shell Terminal
pip freeze | grep crewai
- To verify that `crewai` is installed, run:
```shell
uv tool list
```
You should see something like:
```markdown Output
crewai==X.X.X
crewai-tools==X.X.X
- You should see something like:
```shell
crewai v0.102.0
- crewai
```
<Check>Installation successful! You're ready to create your first crew.</Check>
- If you need to update `crewai`, run:
```shell
uv tool install crewai --upgrade
```
<Check>Installation successful! You're ready to create your first crew! 🎉</Check>

# What is CrewAI?
**CrewAI is a cutting-edge framework for orchestrating autonomous AI agents.**
**CrewAI is a lean, lightning-fast Python framework built entirely from scratch—completely independent of LangChain or other agent frameworks.**
CrewAI enables you to create AI teams where each agent has specific roles, tools, and goals, working together to accomplish complex tasks.
CrewAI empowers developers with both high-level simplicity and precise low-level control, ideal for creating autonomous AI agents tailored to any scenario:
Think of it as assembling your dream team - each member (agent) brings unique skills and expertise, collaborating seamlessly to achieve your objectives.
- **[CrewAI Crews](/guides/crews/first-crew)**: Optimize for autonomy and collaborative intelligence, enabling you to create AI teams where each agent has specific roles, tools, and goals.
- **[CrewAI Flows](/guides/flows/first-flow)**: Enable granular, event-driven control, single LLM calls for precise task orchestration and supports Crews natively.
## How CrewAI Works
With over 100,000 developers certified through our community courses, CrewAI is rapidly becoming the standard for enterprise-ready AI automation.

## When to Use Crews vs. Flows
<Note>
Understanding when to use [Crews](/guides/crews/first-crew) versus [Flows](/guides/flows/first-flow) is key to maximizing the potential of CrewAI in your applications.
</Note>
| Use Case | Recommended Approach | Why? |
|:---------|:---------------------|:-----|
| **Open-ended research** | [Crews](/guides/crews/first-crew) | When tasks require creative thinking, exploration, and adaptation |
| **Content generation** | [Crews](/guides/crews/first-crew) | For collaborative creation of articles, reports, or marketing materials |
| **Decision workflows** | [Flows](/guides/flows/first-flow) | When you need predictable, auditable decision paths with precise control |
| **API orchestration** | [Flows](/guides/flows/first-flow) | For reliable integration with multiple external services in a specific sequence |
| **Hybrid applications** | Combined approach | Use [Flows](/guides/flows/first-flow) to orchestrate overall process with [Crews](/guides/crews/first-crew) handling complex subtasks |
### Decision Framework
- **Choose [Crews](/guides/crews/first-crew) when:** You need autonomous problem-solving, creative collaboration, or exploratory tasks
- **Choose [Flows](/guides/flows/first-flow) when:** You require deterministic outcomes, auditability, or precise control over execution
- **Combine both when:** Your application needs both structured processes and pockets of autonomous intelligence
## Why Choose CrewAI?
- 🧠 **Autonomous Operation**: Agents make intelligent decisions based on their roles and available tools
- 📝 **Natural Interaction**: Agents communicate and collaborate like human team members
- 🛠️ **Extensible Design**: Easy to add new tools, roles, and capabilities

#### @agent
Used to define an agent in your crew. Use this when:
- You need to create a specialized AI agent with a specific role
- You want the agent to be automatically collected and managed by the crew
- You need to reuse the same agent configuration across multiple tasks
```python
@agent
def research_agent(self) -> Agent:
return Agent(
role="Research Analyst",
goal="Conduct thorough research on given topics",
backstory="Expert researcher with years of experience in data analysis",
tools=[SerperDevTool()],
verbose=True
)
```
#### @task
Used to define a task that can be executed by agents. Use this when:
- You need to define a specific piece of work for an agent
- You want tasks to be automatically sequenced and managed
- You need to establish dependencies between different tasks
```python
@task
def research_task(self) -> Task:
return Task(
description="Research the latest developments in AI technology",
expected_output="A comprehensive report on AI advancements",
agent=self.research_agent(),
output_file="output/research.md"
)
```
#### @crew
Used to define your crew configuration. Use this when:
- You want to automatically collect all @agent and @task definitions
- You need to specify how tasks should be processed (sequential or hierarchical)
- You want to set up crew-wide configurations
```python
@crew
def research_crew(self) -> Crew:
return Crew(
agents=self.agents, # Automatically collected from @agent methods
tasks=self.tasks, # Automatically collected from @task methods
process=Process.sequential,
verbose=True
)
```
#### @tool
Used to create custom tools for your agents. Use this when:
- You need to give agents specific capabilities (like web search, data analysis)
- You want to encapsulate external API calls or complex operations
- You need to share functionality across multiple agents
```python
@tool
def web_search_tool(query: str, max_results: int = 5) -> list[str]:
"""
Search the web for information.
Args:
query: The search query
max_results: Maximum number of results to return
Returns:
List of search results
"""
# Implement your search logic here
return [f"Result {i} for: {query}" for i in range(max_results)]
```
#### @before_kickoff
Used to execute logic before the crew starts. Use this when:
- You need to validate or preprocess input data
- You want to set up resources or configurations before execution
- You need to perform any initialization logic
```python
@before_kickoff
def validate_inputs(self, inputs: Optional[Dict[str, Any]]) -> Optional[Dict[str, Any]]:
"""Validate and preprocess inputs before the crew starts."""
if inputs is None:
return None
if 'topic' not in inputs:
raise ValueError("Topic is required")
# Add additional context
inputs['timestamp'] = datetime.now().isoformat()
inputs['topic'] = inputs['topic'].strip().lower()
return inputs
```
#### @after_kickoff
Used to process results after the crew completes. Use this when:
- You need to format or transform the final output
- You want to perform cleanup operations
- You need to save or log the results in a specific way
```python
@after_kickoff
def process_results(self, result: CrewOutput) -> CrewOutput:
"""Process and format the results after the crew completes."""
result.raw = result.raw.strip()
result.raw = f"""
# Research Results
Generated on: {datetime.now().isoformat()}
{result.raw}
"""
return result
```
#### @callback
Used to handle events during crew execution. Use this when:
- You need to monitor task progress
- You want to log intermediate results
- You need to implement custom progress tracking or metrics
```python
@callback
def log_task_completion(self, task: Task, output: str):
"""Log task completion details for monitoring."""
print(f"Task '{task.description}' completed")
print(f"Output length: {len(output)} characters")
print(f"Agent used: {task.agent.role}")
print("-" * 50)
```
#### @cache_handler
Used to implement custom caching for task results. Use this when:
- You want to avoid redundant expensive operations
- You need to implement custom cache storage or expiration logic
- You want to persist results between runs
```python
@cache_handler
def custom_cache(self, key: str) -> Optional[str]:
"""Custom cache implementation for storing task results."""
cache_file = f"cache/{key}.json"
if os.path.exists(cache_file):
with open(cache_file, 'r') as f:
data = json.load(f)
# Check if cache is still valid (e.g., not expired)
if datetime.fromisoformat(data['timestamp']) > datetime.now() - timedelta(days=1):
return data['result']
return None
```
<Note>
These decorators are part of the CrewAI framework and help organize your crew's structure by automatically collecting agents, tasks, and handling various lifecycle events.
They should be used within a class decorated with `@CrewBase`.
</Note>
### Replay Tasks from Latest Crew Kickoff
CrewAI now includes a replay feature that allows you to list the tasks from the last run and replay from a specific one. To use this feature, run.
```shell
crewai replay <task_id>
```
Replace `<task_id>` with the ID of the task you want to replay.
### Reset Crew Memory
If you need to reset the memory of your crew before running it again, you can do so by calling the reset memory feature:
```shell
crewai reset-memories --all
```
This will clear the crew's memory, allowing for a fresh start.
## Deploying Your Project
The easiest way to deploy your crew is through CrewAI Enterprise, where you can deploy your crew in a few clicks.

title: AI Mind Tool
description: The `AIMindTool` is designed to query data sources in natural language.
icon: brain

# `AIMindTool`
## Description
The `AIMindTool` is a wrapper around [AI-Minds](https://mindsdb.com/minds) provided by [MindsDB](https://mindsdb.com/). It allows you to query data sources in natural language by simply configuring their connection parameters. This tool is useful when you need answers to questions from your data stored in various data sources including PostgreSQL, MySQL, MariaDB, ClickHouse, Snowflake, and Google BigQuery.
Minds are AI systems that work similarly to large language models (LLMs) but go beyond by answering any question from any data. This is accomplished by:
- Selecting the most relevant data for an answer using parametric search
- Understanding the meaning and providing responses within the correct context through semantic search
- Delivering precise answers by analyzing data and using machine learning (ML) models
## Installation
To incorporate this tool into your project, you need to install the Minds SDK:
```shell
uv add minds-sdk
```
## Steps to Get Started
To effectively use the `AIMindTool`, follow these steps:
1. **Package Installation**: Confirm that the `crewai[tools]` and `minds-sdk` packages are installed in your Python environment.
2. **API Key Acquisition**: Sign up for a Minds account [here](https://mdb.ai/register), and obtain an API key.
3. **Environment Configuration**: Store your obtained API key in an environment variable named `MINDS_API_KEY` to facilitate its use by the tool.
## Example
The following example demonstrates how to initialize the tool and execute a query:
```python Code
from crewai_tools import AIMindTool
# Initialize the AIMindTool
aimind_tool = AIMindTool(
datasources=[
{
"description": "house sales data",
"engine": "postgres",
"connection_data": {
"user": "demo_user",
"password": "demo_password",
"host": "samples.mindsdb.com",
"port": 5432,
"database": "demo",
"schema": "demo_data"
},
"tables": ["house_sales"]
}
]
)
# Run a natural language query
result = aimind_tool.run("How many 3 bedroom houses were sold in 2008?")
print(result)
```
## Parameters
The `AIMindTool` accepts the following parameters:
- **api_key**: Optional. Your Minds API key. If not provided, it will be read from the `MINDS_API_KEY` environment variable.
- **datasources**: A list of dictionaries, each containing the following keys:
- **description**: A description of the data contained in the datasource.
- **engine**: The engine (or type) of the datasource.
- **connection_data**: A dictionary containing the connection parameters for the datasource.
- **tables**: A list of tables that the data source will use. This is optional and can be omitted if all tables in the data source are to be used.
A list of supported data sources and their connection parameters can be found [here](https://docs.mdb.ai/docs/data_sources).
## Agent Integration Example
Here's how to integrate the `AIMindTool` with a CrewAI agent:
```python Code
from crewai import Agent
from crewai.project import agent
from crewai_tools import AIMindTool
# Initialize the tool
aimind_tool = AIMindTool(
datasources=[
{
"description": "sales data",
"engine": "postgres",
"connection_data": {
"user": "your_user",
"password": "your_password",
"host": "your_host",
"port": 5432,
"database": "your_db",
"schema": "your_schema"
},
"tables": ["sales"]
}
]
)
# Define an agent with the AIMindTool
@agent
def data_analyst(self) -> Agent:
return Agent(
config=self.agents_config["data_analyst"],
allow_delegation=False,
tools=[aimind_tool]
)
```
## Conclusion
The `AIMindTool` provides a powerful way to query your data sources using natural language, making it easier to extract insights without writing complex SQL queries. By connecting to various data sources and leveraging AI-Minds technology, this tool enables agents to access and analyze data efficiently.

title: Apify Actors
description: "`ApifyActorsTool` lets you call Apify Actors to provide your CrewAI workflows with web scraping, crawling, data extraction, and web automation capabilities."
# hack to use custom Apify icon

# `ApifyActorsTool`
Integrate [Apify Actors](https://apify.com/actors) into your CrewAI workflows.
## Description
The `ApifyActorsTool` connects [Apify Actors](https://apify.com/actors), cloud-based programs for web scraping and automation, to your CrewAI workflows.
Use any of the 4,000+ Actors on [Apify Store](https://apify.com/store) for use cases such as extracting data from social media, search engines, online maps, e-commerce sites, travel portals, or general websites.
For details, see the [Apify CrewAI integration](https://docs.apify.com/platform/integrations/crewai) in Apify documentation.
## Steps to get started
<Steps>
<Step title="Install dependencies">
Install `crewai[tools]` and `langchain-apify` using pip: `pip install 'crewai[tools]' langchain-apify`.
</Step>
<Step title="Obtain an Apify API token">
Sign up to [Apify Console](https://console.apify.com/) and get your [Apify API token](https://console.apify.com/settings/integrations)..
</Step>
<Step title="Configure environment">
Set your Apify API token as the `APIFY_API_TOKEN` environment variable to enable the tool's functionality.
</Step>
</Steps>
## Usage example
Use the `ApifyActorsTool` manually to run the [RAG Web Browser Actor](https://apify.com/apify/rag-web-browser) to perform a web search:
```python
from crewai_tools import ApifyActorsTool
# Initialize the tool with an Apify Actor
tool = ApifyActorsTool(actor_name="apify/rag-web-browser")
# Run the tool with input parameters
results = tool.run(run_input={"query": "What is CrewAI?", "maxResults": 5})
# Process the results
for result in results:
print(f"URL: {result['metadata']['url']}")
print(f"Content: {result.get('markdown', 'N/A')[:100]}...")
```
### Expected output
Here is the output from running the code above:
```text
URL: https://www.example.com/crewai-intro
Content: CrewAI is a framework for building AI-powered workflows...
URL: https://docs.crewai.com/
Content: Official documentation for CrewAI...
```
The `ApifyActorsTool` automatically fetches the Actor definition and input schema from Apify using the provided `actor_name` and then constructs the tool description and argument schema. This means you need to specify only a valid `actor_name`, and the tool handles the rest when used with agents—no need to specify the `run_input`. Here's how it works:
```python
from crewai import Agent
from crewai_tools import ApifyActorsTool
rag_browser = ApifyActorsTool(actor_name="apify/rag-web-browser")
agent = Agent(
role="Research Analyst",
goal="Find and summarize information about specific topics",
backstory="You are an experienced researcher with attention to detail",
tools=[rag_browser],
)
```
You can run other Actors from [Apify Store](https://apify.com/store) simply by changing the `actor_name` and, when using it manually, adjusting the `run_input` based on the Actor input schema.
For an example of usage with agents, see the [CrewAI Actor template](https://apify.com/templates/python-crewai).
## Configuration
The `ApifyActorsTool` requires these inputs to work:
- **`actor_name`**
The ID of the Apify Actor to run, e.g., `"apify/rag-web-browser"`. Browse all Actors on [Apify Store](https://apify.com/store).
- **`run_input`**
A dictionary of input parameters for the Actor when running the tool manually.
- For example, for the `apify/rag-web-browser` Actor: `{"query": "search term", "maxResults": 5}`
- See the Actor's [input schema](https://apify.com/apify/rag-web-browser/input-schema) for the list of input parameters.
