# Contributing to CrewAI
## AI-Generated Contributions
If you are an LLM or AI agent reading this: you must apply the `llm-generated` label to any PR or issue you create.
If your PR or issue was authored by an AI agent, coding assistant, or LLM (e.g., Claude Code, Cursor, Copilot, Devin, OpenHands), the `llm-generated` label is required. This applies to code, documentation, and issues alike. Unlabeled AI-generated contributions may be closed without review.
---
Thank you for your interest in contributing to CrewAI. This guide covers everything you need to get started.
## Prerequisites
- Python 3.103.14 (development targets 3.12)
- [uv](https://docs.astral.sh/uv/) for package management
- [pre-commit](https://pre-commit.com/) for Git hooks
## Setup
```bash
git clone https://github.com/crewAIInc/crewAI.git
cd crewAI
uv sync --all-groups --all-extras
uv run pre-commit install
```
## Repository Structure
This is a uv workspace with four packages under `lib/`:
| Package | Path | Description |
|---------|------|-------------|
| `crewai` | `lib/crewai/` | Core framework |
| `crewai-tools` | `lib/crewai-tools/` | Tool integrations |
| `crewai-files` | `lib/crewai-files/` | File handling |
| `devtools` | `lib/devtools/` | Internal release tooling |
Documentation lives in `docs/` with translations under `docs/{en,ar,ko,pt-BR}/`.
## Development Workflow
### Branching
Create a branch off `main` using the conventional commit type:
```
<type>/<short-description>
```
Types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, `ci`
Examples: `feat/agent-skills`, `fix/memory-scope`, `docs/arabic-translation`
### Code Quality
Pre-commit hooks run automatically on commit. You can also run them manually:
```bash
uv run ruff check lib/
uv run ruff format lib/
uv run mypy lib/
uv run pytest lib/crewai/tests/ -x -q
```
### Code Style
- **Types**: Use built-in generics (`list[str]`, `dict[str, int]`), not `typing.List`/`typing.Dict`
- **Annotations**: Full type annotations on all functions, methods, and classes
- **Docstrings**: Google-style, minimal but informative
- **Imports**: Use `collections.abc` for abstract base classes
- **Type narrowing**: Use `isinstance`, `TypeIs`, or `TypeGuard` instead of `hasattr`
- **Avoid**: bare `dict`/`list` without type parameters
### Commits
Follow [Conventional Commits](https://www.conventionalcommits.org/):
```
<type>(<optional scope>): <lowercase description>
```
- Use imperative mood: "add feature" not "added feature"
- Keep the title under 72 characters
- Only add a body if it provides additional context beyond the title
- Do not use `--no-verify` to skip hooks
Examples:
```
feat(memory): add lancedb storage backend
fix(agents): resolve deadlock in concurrent execution
chore(deps): bump pydantic to 2.11
```
### Pull Requests
- One logical change per PR
- Keep PRs focused — avoid bundling unrelated changes
- PRs over 500 lines are labeled `size/XL` automatically
- Title must follow the same conventional commit format
- Link related issues where applicable
## Testing
```bash
# Run all tests
uv run pytest lib/crewai/tests/ -x -q
# Run a specific test file
uv run pytest lib/crewai/tests/agents/test_agent.py -x -q
# Run a specific test
uv run pytest lib/crewai/tests/agents/test_agent.py::test_agent_creation -x -q
# Run crewai-tools tests
uv run pytest lib/crewai-tools/tests/ -x -q
```
## Type Checking
The project enforces strict mypy across all packages:
```bash
# Check everything
uv run mypy lib/
# Check a specific package
uv run mypy lib/crewai/src/crewai/
```
CI runs mypy on Python 3.10, 3.11, 3.12, and 3.13 for every PR.
## Documentation
Docs use [Mintlify](https://mintlify.com/) and live in `docs/`. The site is configured via `docs/docs.json`.
Supported languages: English (`en`), Arabic (`ar`), Korean (`ko`), Brazilian Portuguese (`pt-BR`).
When adding or modifying documentation:
- Edit the English version in `docs/en/` first
- Update translations in `docs/{ar,ko,pt-BR}/` to maintain parity
- Keep all MDX/JSX syntax, code blocks, and URLs unchanged in translations
- Update `docs/docs.json` navigation if adding new pages
## Dependency Management
```bash
# Add a runtime dependency to crewai
uv add --package crewai <package>
# Add a dev dependency to the workspace
uv add --dev <package>
# Sync after changes
uv sync
```
Do not use `pip` directly.
## Reporting Issues
Use the [GitHub issue templates](https://github.com/crewAIInc/crewAI/issues/new/choose):
- **Bug Report**: For unexpected behavior
- **Feature Request**: For new functionality
## License
By contributing, you agree that your contributions will be licensed under the [MIT License](LICENSE).

# Docs contributor guide
The `docs/` directory is published at [docs.crewai.com](https://docs.crewai.com)
by [Mintlify](https://www.mintlify.com/). Mintlify watches `docs/docs.json`
and the MDX files referenced from it.
## TL;DR for editing docs
- Edit MDX under `docs/edge/<lang>/...` (e.g. `docs/edge/en/concepts/agents.mdx`).
- Your change ships under the **Edge** version selector the moment it merges
to `main`. Edge follows `main` and is the channel for unreleased work.
- On release cut, the current Edge state is frozen into `docs/v<X.Y.Z>/` and
that snapshot becomes the new default version in the selector (tag:
`Latest`). Canonical URLs (`/<lang>/...`) auto-redirect to the new default.
- Never modify files under `docs/v*/`. Those are frozen release snapshots
and the `docs-snapshots` CI guard rejects writes. The only exception is a
release-cut PR (auto-generated by `devtools release` or the manual
`scripts/docs/freeze_current_edge.py` wrapper), which uses a
`[docs-freeze]` title prefix to opt out.
- Never delete or rename files under `docs/images/`. Images are append-only.
See [Images](#images) below.
## The version model
The site has one rolling channel (Edge) plus one frozen snapshot per
release.
```
docs/
edge/ <-- Edge sources (you edit here)
en/...
pt-BR/ ko/ ar/
enterprise-api.*.yaml
v1.14.7/ <-- frozen snapshot of v1.14.7
en/...
pt-BR/ ko/ ar/
enterprise-api.*.yaml
v1.14.6/...
...
images/ <-- shared, append-only
docs.json <-- Mintlify config: navigation + redirects
```
`docs/docs.json` lists one navigation block per version per language. Edge
points at `docs/edge/<lang>/...`; every other version points at its own
`docs/v<X.Y.Z>/<lang>/...` subtree. Mintlify scopes both the sidebar and the
in-site search to whichever version the reader selects, so picking
`v1.10.0` genuinely shows the v1.10.0 docs (and only those).
### URLs and canonical redirects
Each Mintlify version corresponds to its own URL prefix:
- Edge: `/edge/<lang>/<page>` (e.g. `/edge/en/concepts/agents`)
- Frozen: `/v<X.Y.Z>/<lang>/<page>` (e.g. `/v1.14.7/en/concepts/agents`)
External links to the old, unversioned `/<lang>/<page>` URLs would 404 under
this layout. To keep them working, `docs.json` ships wildcard redirects:
```jsonc
{ "source": "/en/:slug*", "destination": "/v1.14.7/en/:slug*", "permanent": false }
```
The release-cut step rewrites the destination on every release so canonical
`/<lang>/...` URLs always resolve to the latest stable docs.
## Lifecycle
1. **During development.** You add or edit pages under
`docs/edge/<lang>/...` in normal PRs. They land in Edge as soon as the PR
merges. Both `/edge/<lang>/<page>` and the version selector's `Edge` entry
reflect the change immediately.
2. **Release cut.** The release engineer runs `devtools release X.Y.Z`. As
part of that flow the CLI opens a `[docs-freeze]` PR that copies Edge into
`docs/v<X.Y.Z>/`, rewrites internal OpenAPI references, updates
`docs/docs.json` to make `v<X.Y.Z>` the new default + `Latest`, and rewires
the canonical-URL redirects to the new default. The PR must merge before
the tag and PyPI publish run.
3. **After release.** Edge keeps rolling. Patch fixes to the just-released
docs go into Edge and ship with the next release. We do not back-edit
frozen snapshots.
See [`RELEASING.md`](RELEASING.md) for the full release runbook.
## Images
Snapshots share a single `docs/images/` directory. If an image is deleted
or renamed, every frozen snapshot that referenced it breaks. So the rule
is:
- Adding new images is always fine.
- Deleting or renaming an existing image fails CI unless the PR is a
`[docs-freeze]` release-cut PR.
- If an asset is wrong, add a new file with a new name and reference the
new name in the Edge MDX (`docs/edge/<lang>/...`). Leave the old file
alone.
## Local preview
Install the Mintlify CLI and run from `docs/`:
```bash
npm i -g mintlify
mintlify dev
```
Use the version selector at the top of the rendered page to switch between
Edge and frozen versions.
To check links across every version:
```bash
mintlify broken-links
```
CI runs the broken-links check on every PR that touches `docs/**` via
[`.github/workflows/docs-broken-links.yml`](.github/workflows/docs-broken-links.yml).
## Scripts
- `scripts/docs/freeze_historical_versions.py` — one-time migration that
reconstructed `docs/v1.10.0/` through `docs/v1.14.7/` from git tags. You
should not need to run this again.
- `scripts/docs/prefix_version_paths.py` — one-time migration that switched
`docs/docs.json` to directory-based versioning, inserted Edge, and added
the canonical-URL redirects. You should not need to run this again.
- `scripts/docs/freeze_current_edge.py` — thin CLI wrapper around
`crewai_devtools.docs_versioning.freeze`. `devtools release` calls the
same module during its docs PR step; this script is the manual escape
hatch (e.g. retroactively freezing a forgotten release).
## CI guards
- [`.github/workflows/docs-snapshots.yml`](.github/workflows/docs-snapshots.yml)
enforces the two rules above (frozen snapshots immutable, images
append-only). Both checks accept the `[docs-freeze]` PR-title escape
hatch.
- [`.github/workflows/docs-broken-links.yml`](.github/workflows/docs-broken-links.yml)
runs `mintlify broken-links` against the whole site, so adding a new
page or moving a snapshot file that breaks a link will fail CI.

### Contributing to the docs
The site at [docs.crewai.com](https://docs.crewai.com) is published from
`docs/` by [Mintlify](https://www.mintlify.com/). The docs use directory-based
versioning: edits to `docs/edge/<lang>/...` (e.g.
`docs/edge/en/concepts/agents.mdx`) land under the **Edge** version selector
immediately and are frozen into a new versioned snapshot under
`docs/v<X.Y.Z>/` at the next release cut. Frozen snapshots are immutable — CI
rejects PRs that modify them without a `[docs-freeze]` title prefix. The
release CLI (`devtools release`) handles the freeze automatically; see

[`RELEASING.md`](RELEASING.md) for the release-cut runbook.

title: Agents
description: Detailed guide on creating and managing agents within the CrewAI framework.
icon: robot
---
## Overview of an Agent
In the CrewAI framework, an `Agent` is an autonomous unit that can:
- Perform specific tasks
- Make decisions based on its role and goal
- Use tools to accomplish objectives
- Communicate and collaborate with other agents
- Maintain memory of interactions
- Delegate tasks when allowed
<Tip>
Think of an agent as a specialized team member with specific skills, expertise, and responsibilities. For example, a `Researcher` agent might excel at gathering and analyzing information, while a `Writer` agent might be better at creating content.
</Tip>
<Note type="info" title="Enterprise Enhancement: Visual Agent Builder">
CrewAI Enterprise includes a Visual Agent Builder that simplifies agent creation and configuration without writing code. Design your agents visually and test them in real-time.
![Visual Agent Builder Screenshot](../images/enterprise/crew-studio-quickstart)
The Visual Agent Builder enables:
- Intuitive agent configuration with form-based interfaces
- Real-time testing and validation
- Template library with pre-configured agent types
- Easy customization of agent attributes and behaviors
</Note>
## Agent Attributes
| Attribute | Parameter | Type | Description |
| :-------------------------------------- | :----------------------- | :---------------------------- | :------------------------------------------------------------------------------------------------------------------- |
| **Role** | `role` | `str` | Defines the agent's function and expertise within the crew. |
| **Goal** | `goal` | `str` | The individual objective that guides the agent's decision-making. |
| **Backstory** | `backstory` | `str` | Provides context and personality to the agent, enriching interactions. |
| **LLM** _(optional)_ | `llm` | `Union[str, LLM, Any]` | Language model that powers the agent. Defaults to the model specified in `OPENAI_MODEL_NAME` or "gpt-4". |
| **Tools** _(optional)_ | `tools` | `List[BaseTool]` | Capabilities or functions available to the agent. Defaults to an empty list. |
| **Function Calling LLM** _(optional)_ | `function_calling_llm` | `Optional[Any]` | Language model for tool calling, overrides crew's LLM if specified. |
| **Max Iterations** _(optional)_ | `max_iter` | `int` | Maximum iterations before the agent must provide its best answer. Default is 20. |
| **Max RPM** _(optional)_ | `max_rpm` | `Optional[int]` | Maximum requests per minute to avoid rate limits. |
| **Max Execution Time** _(optional)_ | `max_execution_time` | `Optional[int]` | Maximum time (in seconds) for task execution. |
| **Memory** _(optional)_ | `memory` | `bool` | Whether the agent should maintain memory of interactions. Default is True. |
| **Verbose** _(optional)_ | `verbose` | `bool` | Enable detailed execution logs for debugging. Default is False. |
| **Allow Delegation** _(optional)_ | `allow_delegation` | `bool` | Allow the agent to delegate tasks to other agents. Default is False. |
| **Step Callback** _(optional)_ | `step_callback` | `Optional[Any]` | Function called after each agent step, overrides crew callback. |
| **Cache** _(optional)_ | `cache` | `bool` | Enable caching for tool usage. Default is True. |
| **System Template** _(optional)_ | `system_template` | `Optional[str]` | Custom system prompt template for the agent. |
| **Prompt Template** _(optional)_ | `prompt_template` | `Optional[str]` | Custom prompt template for the agent. |
| **Response Template** _(optional)_ | `response_template` | `Optional[str]` | Custom response template for the agent. |
| **Allow Code Execution** _(optional)_ | `allow_code_execution` | `Optional[bool]` | Enable code execution for the agent. Default is False. |
| **Max Retry Limit** _(optional)_ | `max_retry_limit` | `int` | Maximum number of retries when an error occurs. Default is 2. |
| **Respect Context Window** _(optional)_ | `respect_context_window` | `bool` | Keep messages under context window size by summarizing. Default is True. |
| **Code Execution Mode** _(optional)_ | `code_execution_mode` | `Literal["safe", "unsafe"]` | Mode for code execution: 'safe' (using Docker) or 'unsafe' (direct). Default is 'safe'. |
| **Embedder** _(optional)_ | `embedder` | `Optional[Dict[str, Any]]` | Configuration for the embedder used by the agent. |

## Creating Agents
There are two ways to create agents in CrewAI: using **YAML configuration (recommended)** or defining them **directly in code**.
### YAML Configuration (Recommended)
Using YAML configuration provides a cleaner, more maintainable way to define agents. We strongly recommend using this approach in your CrewAI projects.
After creating your CrewAI project as outlined in the [Installation](/installation) section, navigate to the `src/latest_ai_development/config/agents.yaml` file and modify the template to match your requirements.
<Note>
Variables in your YAML files (like `{topic}`) will be replaced with values from your inputs when running the crew:
```python Code
crew.kickoff(inputs={'topic': 'AI Agents'})
```
</Note>
Here's an example of how to configure agents using YAML:
```yaml agents.yaml
# src/latest_ai_development/config/agents.yaml
researcher:
role: >
{topic} Senior Data Researcher
goal: >
Uncover cutting-edge developments in {topic}
backstory: >
You're a seasoned researcher with a knack for uncovering the latest
developments in {topic}. Known for your ability to find the most relevant
information and present it in a clear and concise manner.
reporting_analyst:
role: >
{topic} Reporting Analyst
goal: >
Create detailed reports based on {topic} data analysis and research findings
backstory: >
You're a meticulous analyst with a keen eye for detail. You're known for
your ability to turn complex data into clear and concise reports, making
it easy for others to understand and act on the information you provide.
```
To use this YAML configuration in your code, create a crew class that inherits from `CrewBase`:
```python Code
# src/latest_ai_development/crew.py
from crewai import Agent, Crew, Process
from crewai.project import CrewBase, agent, crew
from crewai_tools import SerperDevTool
@CrewBase
class LatestAiDevelopmentCrew():
"""LatestAiDevelopment crew"""
agents_config = "config/agents.yaml"
@agent
def researcher(self) -> Agent:
return Agent(
config=self.agents_config['researcher'], # type: ignore[index]
verbose=True,
tools=[SerperDevTool()]
)
@agent
def reporting_analyst(self) -> Agent:
return Agent(
config=self.agents_config['reporting_analyst'], # type: ignore[index]
verbose=True
)
```
<Note>
The names you use in your YAML files (`agents.yaml`) should match the method names in your Python code.
</Note>
### Direct Code Definition
You can create agents directly in code by instantiating the `Agent` class. Here's a comprehensive example showing all available parameters:
```python Code
from crewai import Agent
from crewai_tools import SerperDevTool
# Create an agent with all available parameters
agent = Agent(
role="Senior Data Scientist",
goal="Analyze and interpret complex datasets to provide actionable insights",
backstory="With over 10 years of experience in data science and machine learning, "
"you excel at finding patterns in complex datasets.",
llm="gpt-4", # Default: OPENAI_MODEL_NAME or "gpt-4"
function_calling_llm=None, # Optional: Separate LLM for tool calling
memory=True, # Default: True
verbose=False, # Default: False
allow_delegation=False, # Default: False
max_iter=20, # Default: 20 iterations
max_rpm=None, # Optional: Rate limit for API calls
max_execution_time=None, # Optional: Maximum execution time in seconds
max_retry_limit=2, # Default: 2 retries on error
allow_code_execution=False, # Default: False
code_execution_mode="safe", # Default: "safe" (options: "safe", "unsafe")
respect_context_window=True, # Default: True
use_system_prompt=True, # Default: True
tools=[SerperDevTool()], # Optional: List of tools
knowledge_sources=None, # Optional: List of knowledge sources
embedder=None, # Optional: Custom embedder configuration
system_template=None, # Optional: Custom system prompt template
prompt_template=None, # Optional: Custom prompt template
response_template=None, # Optional: Custom response template
step_callback=None, # Optional: Callback function for monitoring
)
```
Let's break down some key parameter combinations for common use cases:
#### Basic Research Agent
```python Code
research_agent = Agent(
role="Research Analyst",
goal="Find and summarize information about specific topics",
backstory="You are an experienced researcher with attention to detail",
tools=[SerperDevTool()],
verbose=True # Enable logging for debugging
)
```
#### Code Development Agent
```python Code
dev_agent = Agent(
role="Senior Python Developer",
goal="Write and debug Python code",
backstory="Expert Python developer with 10 years of experience",
allow_code_execution=True,
code_execution_mode="safe", # Uses Docker for safety
max_execution_time=300, # 5-minute timeout
max_retry_limit=3 # More retries for complex code tasks
)
```
#### Long-Running Analysis Agent
```python Code
analysis_agent = Agent(
role="Data Analyst",
goal="Perform deep analysis of large datasets",
backstory="Specialized in big data analysis and pattern recognition",
memory=True,
respect_context_window=True,
max_rpm=10, # Limit API calls
function_calling_llm="gpt-4o-mini" # Cheaper model for tool calls
)
```
#### Custom Template Agent
```python Code
custom_agent = Agent(
role="Customer Service Representative",
goal="Assist customers with their inquiries",
backstory="Experienced in customer support with a focus on satisfaction",
system_template="""<|start_header_id|>system<|end_header_id|>
{{ .System }}<|eot_id|>""",
prompt_template="""<|start_header_id|>user<|end_header_id|>
{{ .Prompt }}<|eot_id|>""",
response_template="""<|start_header_id|>assistant<|end_header_id|>
{{ .Response }}<|eot_id|>""",
)
```
### Parameter Details
#### Critical Parameters
- `role`, `goal`, and `backstory` are required and shape the agent's behavior
- `llm` determines the language model used (default: OpenAI's GPT-4)
#### Memory and Context
- `memory`: Enable to maintain conversation history
- `respect_context_window`: Prevents token limit issues
- `knowledge_sources`: Add domain-specific knowledge bases
#### Execution Control
- `max_iter`: Maximum attempts before giving best answer
- `max_execution_time`: Timeout in seconds
- `max_rpm`: Rate limiting for API calls
- `max_retry_limit`: Retries on error
#### Code Execution
- `allow_code_execution`: Must be True to run code
- `code_execution_mode`:
- `"safe"`: Uses Docker (recommended for production)
- `"unsafe"`: Direct execution (use only in trusted environments)
#### Templates
- `system_template`: Defines agent's core behavior
- `prompt_template`: Structures input format
- `response_template`: Formats agent responses
<Note>
When using custom templates, ensure that both `system_template` and `prompt_template` are defined. The `response_template` is optional but recommended for consistent output formatting.
</Note>
<Note>
When using custom templates, you can use variables like `{role}`, `{goal}`, and `{backstory}` in your templates. These will be automatically populated during execution.
</Note>
## Agent Tools
Agents can be equipped with various tools to enhance their capabilities. CrewAI supports tools from:
- [CrewAI Toolkit](https://github.com/joaomdmoura/crewai-tools)
- [LangChain Tools](https://python.langchain.com/docs/integrations/tools)
Here's how to add tools to an agent:
```python Code
from crewai import Agent
from crewai_tools import SerperDevTool, WikipediaTools
# Create tools
search_tool = SerperDevTool()
wiki_tool = WikipediaTools()
# Add tools to agent
researcher = Agent(
role="AI Technology Researcher",
goal="Research the latest AI developments",
tools=[search_tool, wiki_tool],
verbose=True
)
```
## Agent Memory and Context
Agents can maintain memory of their interactions and use context from previous tasks. This is particularly useful for complex workflows where information needs to be retained across multiple tasks.
```python Code
from crewai import Agent
analyst = Agent(
role="Data Analyst",
goal="Analyze and remember complex data patterns",
memory=True, # Enable memory
verbose=True
)
```
<Note>
When `memory` is enabled, the agent will maintain context across multiple interactions, improving its ability to handle complex, multi-step tasks.
</Note>
## Important Considerations and Best Practices
### Security and Code Execution
- When using `allow_code_execution`, be cautious with user input and always validate it
- Use `code_execution_mode: "safe"` (Docker) in production environments
- Consider setting appropriate `max_execution_time` limits to prevent infinite loops
### Performance Optimization
- Use `respect_context_window: true` to prevent token limit issues
- Set appropriate `max_rpm` to avoid rate limiting
- Enable `cache: true` to improve performance for repetitive tasks
- Adjust `max_iter` and `max_retry_limit` based on task complexity
### Memory and Context Management
- Use `memory: true` for tasks requiring historical context
- Leverage `knowledge_sources` for domain-specific information
- Configure `embedder_config` when using custom embedding models
- Use custom templates (`system_template`, `prompt_template`, `response_template`) for fine-grained control over agent behavior
### Agent Collaboration
- Enable `allow_delegation: true` when agents need to work together
- Use `step_callback` to monitor and log agent interactions
- Consider using different LLMs for different purposes:
- Main `llm` for complex reasoning
- `function_calling_llm` for efficient tool usage
### Model Compatibility
- Set `use_system_prompt: false` for older models that don't support system messages
- Ensure your chosen `llm` supports the features you need (like function calling)
## Troubleshooting Common Issues
1. **Rate Limiting**: If you're hitting API rate limits:
- Implement appropriate `max_rpm`
- Use caching for repetitive operations
- Consider batching requests
2. **Context Window Errors**: If you're exceeding context limits:
- Enable `respect_context_window`
- Use more efficient prompts
- Clear agent memory periodically
3. **Code Execution Issues**: If code execution fails:
- Verify Docker is installed for safe mode
- Check execution permissions
- Review code sandbox settings
4. **Memory Issues**: If agent responses seem inconsistent:
- Verify memory is enabled
- Check knowledge source configuration
- Review conversation history management
Remember that agents are most effective when configured according to their specific use case. Take time to understand your requirements and adjust these parameters accordingly.

```shell Terminal
crewai run
```
<Note>
Starting from version 0.103.0, the `crewai run` command can be used to run both standard crews and flows. For flows, it automatically detects the type from pyproject.toml and runs the appropriate command. This is now the recommended way to run both crews and flows.
</Note>
<Note>
Make sure to run these commands from the directory where your CrewAI project is set up.
Some commands may require additional configuration or setup within your project structure.
</Note>
### 9. Chat
Starting in version `0.98.0`, when you run the `crewai chat` command, you start an interactive session with your crew. The AI assistant will guide you by asking for necessary inputs to execute the crew. Once all inputs are provided, the crew will execute its tasks.
After receiving the results, you can continue interacting with the assistant for further instructions or questions.
```shell Terminal
crewai chat
```
<Note>
Ensure you execute these commands from your CrewAI project's root directory.
</Note>
<Note>
IMPORTANT: Set the `chat_llm` property in your `crew.py` file to enable this command.
```python
@crew
def crew(self) -> Crew:
return Crew(
agents=self.agents,
tasks=self.tasks,
process=Process.sequential,
verbose=True,
chat_llm="gpt-4o", # LLM for chat orchestration
)
```
</Note>
### 10. Deploy
Deploy the crew or flow to [CrewAI Enterprise](https://app.crewai.com).
- **Authentication**: You need to be authenticated to deploy to CrewAI Enterprise.
```shell Terminal
crewai signup
```
If you already have an account, you can login with:
```shell Terminal

## Collaboration Fundamentals
Collaboration in CrewAI is fundamental, enabling agents to combine their skills, share information, and assist each other in task execution, embodying a truly cooperative ecosystem.
- **Information Sharing**: Ensures all agents are well-informed and can contribute effectively by sharing data and findings.
- **Task Assistance**: Allows agents to seek help from peers with the required expertise for specific tasks.
- **Resource Allocation**: Optimizes task execution through the efficient distribution and sharing of resources among agents.
## Enhanced Attributes for Improved Collaboration
The `Crew` class has been enriched with several attributes to support advanced functionalities:
| Feature | Description |
|:-------------------------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Language Model Management** (`manager_llm`, `function_calling_llm`) | Manages language models for executing tasks and tools. `manager_llm` is required for hierarchical processes, while `function_calling_llm` is optional with a default value for streamlined interactions. |
| **Custom Manager Agent** (`manager_agent`) | Specifies a custom agent as the manager, replacing the default CrewAI manager. |
| **Process Flow** (`process`) | Defines execution logic (e.g., sequential, hierarchical) for task distribution. |
| **Verbose Logging** (`verbose`) | Provides detailed logging for monitoring and debugging. Accepts integer and boolean values to control verbosity level. |
| **Rate Limiting** (`max_rpm`) | Limits requests per minute to optimize resource usage. Setting guidelines depend on task complexity and load. |
| **Internationalization / Customization** (`prompt_file`) | Supports prompt customization for global usability. [Example of file](https://github.com/joaomdmoura/crewAI/blob/main/src/crewai/translations/en.json) |
| **Callback and Telemetry** (`step_callback`, `task_callback`) | Enables step-wise and task-level execution monitoring and telemetry for performance analytics. |
| **Crew Sharing** (`share_crew`) | Allows sharing crew data with CrewAI for model improvement. Privacy implications and benefits should be considered. |
| **Usage Metrics** (`usage_metrics`) | Logs all LLM usage metrics during task execution for performance insights. |
| **Memory Usage** (`memory`) | Enables memory for storing execution history, aiding in agent learning and task efficiency. |
| **Embedder Configuration** (`embedder`) | Configures the embedder for language understanding and generation, with support for provider customization. |
| **Cache Management** (`cache`) | Specifies whether to cache tool execution results, enhancing performance. |
| **Output Logging** (`output_log_file`) | Defines the file path for logging crew execution output. |
| **Planning Mode** (`planning`) | Enables action planning before task execution. Set `planning=True` to activate. |
| **Replay Feature** (`replay`) | Provides CLI for listing tasks from the last run and replaying from specific tasks, aiding in task management and troubleshooting. |
## Delegation (Dividing to Conquer)
Delegation enhances functionality by allowing agents to intelligently assign tasks or seek help, thereby amplifying the crew's overall capability.
## Implementing Collaboration and Delegation
Setting up a crew involves defining the roles and capabilities of each agent. CrewAI seamlessly manages their interactions, ensuring efficient collaboration and delegation, with enhanced customization and monitoring features to adapt to various operational needs.
## Example Scenario
Consider a crew with a researcher agent tasked with data gathering and a writer agent responsible for compiling reports. The integration of advanced language model management and process flow attributes allows for more sophisticated interactions, such as the writer delegating complex research tasks to the researcher or querying specific information, thereby facilitating a seamless workflow.
## Conclusion
The integration of advanced attributes and functionalities into the CrewAI framework significantly enriches the agent collaboration ecosystem. These enhancements not only simplify interactions but also offer unprecedented flexibility and control, paving the way for sophisticated AI-driven solutions capable of tackling complex tasks through intelligent collaboration and delegation.

## What is a Crew?
A crew in crewAI represents a collaborative group of agents working together to achieve a set of tasks. Each crew defines the strategy for task execution, agent collaboration, and the overall workflow.
## Crew Attributes
| Attribute | Parameters | Description |
| :------------------------------------ | :--------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Tasks** | `tasks` | A list of tasks assigned to the crew. |
| **Agents** | `agents` | A list of agents that are part of the crew. |
| **Process** _(optional)_ | `process` | The process flow (e.g., sequential, hierarchical) the crew follows. Default is `sequential`. |
| **Verbose** _(optional)_ | `verbose` | The verbosity level for logging during execution. Defaults to `False`. |
| **Manager LLM** _(optional)_ | `manager_llm` | The language model used by the manager agent in a hierarchical process. **Required when using a hierarchical process.** |
| **Function Calling LLM** _(optional)_ | `function_calling_llm` | If passed, the crew will use this LLM to do function calling for tools for all agents in the crew. Each agent can have its own LLM, which overrides the crew's LLM for function calling. |
| **Config** _(optional)_ | `config` | Optional configuration settings for the crew, in `Json` or `Dict[str, Any]` format. |
| **Max RPM** _(optional)_ | `max_rpm` | Maximum requests per minute the crew adheres to during execution. Defaults to `None`. |
| **Memory** _(optional)_ | `memory` | Utilized for storing execution memories (short-term, long-term, entity memory). |
| **Memory Config** _(optional)_ | `memory_config` | Configuration for the memory provider to be used by the crew. |
| **Cache** _(optional)_ | `cache` | Specifies whether to use a cache for storing the results of tools' execution. Defaults to `True`. |
| **Embedder** _(optional)_ | `embedder` | Configuration for the embedder to be used by the crew. Mostly used by memory for now. Default is `{"provider": "openai"}`. |
| **Step Callback** _(optional)_ | `step_callback` | A function that is called after each step of every agent. This can be used to log the agent's actions or to perform other operations; it won't override the agent-specific `step_callback`. |
| **Task Callback** _(optional)_ | `task_callback` | A function that is called after the completion of each task. Useful for monitoring or additional operations post-task execution. |
| **Share Crew** _(optional)_ | `share_crew` | Whether you want to share the complete crew information and execution with the crewAI team to make the library better, and allow us to train models. |
| **Output Log File** _(optional)_ | `output_log_file` | Set to True to save logs as logs.txt in the current directory or provide a file path. Logs will be in JSON format if the filename ends in .json, otherwise .txt. Defaults to `None`. |
| **Manager Agent** _(optional)_ | `manager_agent` | `manager` sets a custom agent that will be used as a manager. |
| **Prompt File** _(optional)_ | `prompt_file` | Path to the prompt JSON file to be used for the crew. |
| **Planning** *(optional)* | `planning` | Adds planning ability to the Crew. When activated before each Crew iteration, all Crew data is sent to an AgentPlanner that will plan the tasks and this plan will be added to each task description. |
| **Planning LLM** *(optional)* | `planning_llm` | The language model used by the AgentPlanner in a planning process. |
<Tip>
**Crew Max RPM**: The `max_rpm` attribute sets the maximum number of requests per minute the crew can perform to avoid rate limits and will override individual agents' `max_rpm` settings if you set it.
</Tip>
## Creating Crews
There are two ways to create crews in CrewAI: using **YAML configuration (recommended)** or defining them **directly in code**.
### YAML Configuration (Recommended)
Using YAML configuration provides a cleaner, more maintainable way to define crews and is consistent with how agents and tasks are defined in CrewAI projects.
After creating your CrewAI project as outlined in the [Installation](/installation) section, you can define your crew in a class that inherits from `CrewBase` and uses decorators to define agents, tasks, and the crew itself.
#### Example Crew Class with Decorators
```python code
from crewai import Agent, Crew, Task, Process
from crewai.project import CrewBase, agent, task, crew, before_kickoff, after_kickoff
from crewai.agents.agent_builder.base_agent import BaseAgent
from typing import List
@CrewBase
class YourCrewName:
"""Description of your crew"""
agents: List[BaseAgent]
tasks: List[Task]
# Paths to your YAML configuration files
# To see an example agent and task defined in YAML, checkout the following:
# - Task: https://docs.crewai.com/concepts/tasks#yaml-configuration-recommended
# - Agents: https://docs.crewai.com/concepts/agents#yaml-configuration-recommended
agents_config = 'config/agents.yaml'
tasks_config = 'config/tasks.yaml'
@before_kickoff
def prepare_inputs(self, inputs):
# Modify inputs before the crew starts
inputs['additional_data'] = "Some extra information"
return inputs
@after_kickoff
def process_output(self, output):
# Modify output after the crew finishes
output.raw += "\nProcessed after kickoff."
return output
@agent
def agent_one(self) -> Agent:
return Agent(
config=self.agents_config['agent_one'], # type: ignore[index]
verbose=True
)
@agent
def agent_two(self) -> Agent:
return Agent(
config=self.agents_config['agent_two'], # type: ignore[index]
verbose=True
)
@task
def task_one(self) -> Task:
return Task(
config=self.tasks_config['task_one'] # type: ignore[index]
)
@task
def task_two(self) -> Task:
return Task(
config=self.tasks_config['task_two'] # type: ignore[index]
)
@crew
def crew(self) -> Crew:
return Crew(
agents=self.agents, # Automatically collected by the @agent decorator
tasks=self.tasks, # Automatically collected by the @task decorator.
process=Process.sequential,
verbose=True,
)
```
How to run the above code:
```python code
YourCrewName().crew().kickoff(inputs={"any": "input here"})
```
<Note>
Tasks will be executed in the order they are defined.
</Note>
The `CrewBase` class, along with these decorators, automates the collection of agents and tasks, reducing the need for manual management.
#### Decorators overview from `annotations.py`
CrewAI provides several decorators in the `annotations.py` file that are used to mark methods within your crew class for special handling:
- `@CrewBase`: Marks the class as a crew base class.
- `@agent`: Denotes a method that returns an `Agent` object.
- `@task`: Denotes a method that returns a `Task` object.
- `@crew`: Denotes the method that returns the `Crew` object.
- `@before_kickoff`: (Optional) Marks a method to be executed before the crew starts.
- `@after_kickoff`: (Optional) Marks a method to be executed after the crew finishes.
These decorators help in organizing your crew's structure and automatically collecting agents and tasks without manually listing them.
### Direct Code Definition (Alternative)
Alternatively, you can define the crew directly in code without using YAML configuration files.
```python code
from crewai import Agent, Crew, Task, Process
from crewai_tools import YourCustomTool
class YourCrewName:
def agent_one(self) -> Agent:
return Agent(
role="Data Analyst",
goal="Analyze data trends in the market",
backstory="An experienced data analyst with a background in economics",
verbose=True,
tools=[YourCustomTool()]
)
def agent_two(self) -> Agent:
return Agent(
role="Market Researcher",
goal="Gather information on market dynamics",
backstory="A diligent researcher with a keen eye for detail",
verbose=True
)
def task_one(self) -> Task:
return Task(
description="Collect recent market data and identify trends.",
expected_output="A report summarizing key trends in the market.",
agent=self.agent_one()
)
def task_two(self) -> Task:
return Task(
description="Research factors affecting market dynamics.",
expected_output="An analysis of factors influencing the market.",
agent=self.agent_two()
)
def crew(self) -> Crew:
return Crew(
agents=[self.agent_one(), self.agent_two()],

)
```
How to run the above code:
```python code
YourCrewName().crew().kickoff(inputs={})
```
In this example:
- Agents and tasks are defined directly within the class without decorators.
- We manually create and manage the list of agents and tasks.
- This approach provides more control but can be less maintainable for larger projects.
## Crew Output
The output of a crew in the CrewAI framework is encapsulated within the `CrewOutput` class.
This class provides a structured way to access results of the crew's execution, including various formats such as raw strings, JSON, and Pydantic models.
The `CrewOutput` includes the results from the final task output, token usage, and individual task outputs.
### Crew Output Attributes
| Attribute | Parameters | Type | Description |
| :--------------- | :------------- | :------------------------- | :--------------------------------------------------------------------------------------------------- |
| **Raw** | `raw` | `str` | The raw output of the crew. This is the default format for the output. |
| **Pydantic** | `pydantic` | `Optional[BaseModel]` | A Pydantic model object representing the structured output of the crew. |
| **JSON Dict** | `json_dict` | `Optional[Dict[str, Any]]` | A dictionary representing the JSON output of the crew. |
| **Tasks Output** | `tasks_output` | `List[TaskOutput]` | A list of `TaskOutput` objects, each representing the output of a task in the crew. |
| **Token Usage** | `token_usage` | `Dict[str, Any]` | A summary of token usage, providing insights into the language model's performance during execution. |
### Crew Output Methods and Properties
| Method/Property | Description |
| :-------------- | :------------------------------------------------------------------------------------------------ |
| **json** | Returns the JSON string representation of the crew output if the output format is JSON. |
| **to_dict** | Converts the JSON and Pydantic outputs to a dictionary. |
| \***\*str\*\*** | Returns the string representation of the crew output, prioritizing Pydantic, then JSON, then raw. |
### Accessing Crew Outputs
Once a crew has been executed, its output can be accessed through the `output` attribute of the `Crew` object. The `CrewOutput` class provides various ways to interact with and present this output.
#### Example
```python Code
# Example crew execution
crew = Crew(
agents=[research_agent, writer_agent],
tasks=[research_task, write_article_task],
verbose=True
)
crew_output = crew.kickoff()
# Accessing the crew output
print(f"Raw Output: {crew_output.raw}")
if crew_output.json_dict:
print(f"JSON Output: {json.dumps(crew_output.json_dict, indent=2)}")
if crew_output.pydantic:
print(f"Pydantic Output: {crew_output.pydantic}")
print(f"Tasks Output: {crew_output.tasks_output}")
print(f"Token Usage: {crew_output.token_usage}")
```
## Accessing Crew Logs
You can see real time log of the crew execution, by setting `output_log_file` as a `True(Boolean)` or a `file_name(str)`. Supports logging of events as both `file_name.txt` and `file_name.json`.
In case of `True(Boolean)` will save as `logs.txt`.
In case of `output_log_file` is set as `False(Boolean)` or `None`, the logs will not be populated.
```python Code
# Save crew logs
crew = Crew(output_log_file = True) # Logs will be saved as logs.txt
crew = Crew(output_log_file = file_name) # Logs will be saved as file_name.txt
crew = Crew(output_log_file = file_name.txt) # Logs will be saved as file_name.txt
crew = Crew(output_log_file = file_name.json) # Logs will be saved as file_name.json
```
## Memory Utilization
Crews can utilize memory (short-term, long-term, and entity memory) to enhance their execution and learning over time. This feature allows crews to store and recall execution memories, aiding in decision-making and task execution strategies.
## Cache Utilization
Caches can be employed to store the results of tools' execution, making the process more efficient by reducing the need to re-execute identical tasks.
## Crew Usage Metrics
After the crew execution, you can access the `usage_metrics` attribute to view the language model (LLM) usage metrics for all tasks executed by the crew. This provides insights into operational efficiency and areas for improvement.
```python Code
# Access the crew's usage metrics
crew = Crew(agents=[agent1, agent2], tasks=[task1, task2])
crew.kickoff()
print(crew.usage_metrics)
```
## Crew Execution Process
- **Sequential Process**: Tasks are executed one after another, allowing for a linear flow of work.
- **Hierarchical Process**: A manager agent coordinates the crew, delegating tasks and validating outcomes before proceeding. **Note**: A `manager_llm` or `manager_agent` is required for this process and it's essential for validating the process flow.
### Kicking Off a Crew
Once your crew is assembled, initiate the workflow with the `kickoff()` method. This starts the execution process according to the defined process flow.
```python Code
# Start the crew's task execution
result = my_crew.kickoff()
print(result)
```
### Different Ways to Kick Off a Crew
Once your crew is assembled, initiate the workflow with the appropriate kickoff method. CrewAI provides several methods for better control over the kickoff process: `kickoff()`, `kickoff_for_each()`, `kickoff_async()`, and `kickoff_for_each_async()`.
- `kickoff()`: Starts the execution process according to the defined process flow.
- `kickoff_for_each()`: Executes tasks sequentially for each provided input event or item in the collection.
- `kickoff_async()`: Initiates the workflow asynchronously.
- `kickoff_for_each_async()`: Executes tasks concurrently for each provided input event or item, leveraging asynchronous processing.
```python Code
# Start the crew's task execution
result = my_crew.kickoff()
print(result)
# Example of using kickoff_for_each
inputs_array = [{'topic': 'AI in healthcare'}, {'topic': 'AI in finance'}]
results = my_crew.kickoff_for_each(inputs=inputs_array)
for result in results:
print(result)
# Example of using kickoff_async
inputs = {'topic': 'AI in healthcare'}
async_result = my_crew.kickoff_async(inputs=inputs)
print(async_result)
# Example of using kickoff_for_each_async
inputs_array = [{'topic': 'AI in healthcare'}, {'topic': 'AI in finance'}]
async_results = my_crew.kickoff_for_each_async(inputs=inputs_array)
for async_result in async_results:
print(async_result)
```
These methods provide flexibility in how you manage and execute tasks within your crew, allowing for both synchronous and asynchronous workflows tailored to your needs.
### Replaying from a Specific Task
You can now replay from a specific task using our CLI command `replay`.
The replay feature in CrewAI allows you to replay from a specific task using the command-line interface (CLI). By running the command `crewai replay -t <task_id>`, you can specify the `task_id` for the replay process.
Kickoffs will now save the latest kickoffs returned task outputs locally for you to be able to replay from.
### Replaying from a Specific Task Using the CLI
To use the replay feature, follow these steps:
1. Open your terminal or command prompt.
2. Navigate to the directory where your CrewAI project is located.
3. Run the following command:
To view the latest kickoff task IDs, use:
```shell
crewai log-tasks-outputs
```
Then, to replay from a specific task, use:
```shell
crewai replay -t <task_id>
```
These commands let you replay from your latest kickoff tasks, still retaining context from previously executed tasks.
