Build with AI

Using an AI coding agent? Teach it CrewAI best practices in one command:

Claude Code:

/plugin marketplace add crewAIInc/skills
/plugin install crewai-skills@crewai-plugins
/reload-plugins

Cursor, Codex, Windsurf, and others (skills.sh):

npx skills add crewaiinc/skills

This installs the official CrewAI Skills — structured instructions that teach coding agents how to scaffold Flows, configure Crews, design agents and tasks, and follow CrewAI patterns.

Getting Started

Setup and run your first CrewAI agents by following this tutorial.

Getting Started with Installation

To get started with CrewAI, follow these simple steps:

1. Installation

Ensure you have Python >=3.10 <3.14 installed on your system. CrewAI uses UV for dependency management and package handling, offering a seamless setup and execution experience.

First, install CrewAI:

uv pip install crewai

If you want to install the 'crewai' package along with its optional features that include additional tools for agents, you can do so by using the following command:

uv pip install 'crewai[tools]'

The command above installs the basic package and also adds extra components which require more dependencies to function.

Installing Locally

uv pip install dist/*.tar.gz

Q: How do I install CrewAI?

A: Install CrewAI using pip:

uv pip install crewai

For additional tools, use:

uv pip install 'crewai[tools]'

Q: Is CrewAI AMP available for cloud and on-premise deployments?

A: Yes, CrewAI AMP supports both cloud-based and on-premise deployment options, allowing enterprises to meet their specific security and compliance requirements.

Examples

You can test different real life examples of AI crews in the CrewAI-examples repo:

• Landing Page Generator
• Having Human input on the execution
• Trip Planner
• Stock Analysis

Quick Tutorial

Q: Can CrewAI handle complex use cases?

A: Yes. CrewAI excels at both simple and highly complex real-world scenarios, offering deep customization options at both high and low levels, from internal prompts to sophisticated workflow orchestration.

Q: Where can I find real-world CrewAI examples?

A: Check out practical examples in the CrewAI-examples repository, covering use cases like trip planners, stock analysis, and job postings.

2. Setting Up Your Crew with the YAML Configuration

To create a new CrewAI project, run the following CLI (Command Line Interface) command:

crewai create crew <project_name>

This command creates a new project folder with the following structure:

my_project/
├── .gitignore
├── pyproject.toml
├── README.md
├── .env
└── src/
    └── my_project/
        ├── __init__.py
        ├── main.py
        ├── crew.py
        ├── tools/
        │   ├── custom_tool.py
        │   └── __init__.py
        └── config/
            ├── agents.yaml
            └── tasks.yaml

You can now start developing your crew by editing the files in the src/my_project folder. The main.py file is the entry point of the project, the crew.py file is where you define your crew, the agents.yaml file is where you define your agents, and the tasks.yaml file is where you define your tasks.

To customize your project, you can:

• Modify src/my_project/config/agents.yaml to define your agents.
• Modify src/my_project/config/tasks.yaml to define your tasks.
• Modify src/my_project/crew.py to add your own logic, tools, and specific arguments.
• Modify src/my_project/main.py to add custom inputs for your agents and tasks.
• Add your environment variables into the .env file.

Example of a simple crew with a sequential process:

Instantiate your crew:

crewai create crew latest-ai-development

Modify the files as needed to fit your use case:

agents.yaml

```yaml

src/my_project/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.

**tasks.yaml**

src/my_project/config/tasks.yaml

research_task: description: > Conduct a thorough research about {topic} Make sure you find any interesting and relevant information given the current year is 2025. expected_output: > A list with 10 bullet points of the most relevant information about {topic} agent: researcher

reporting_task: description: > Review the context you got and expand each topic into a full section for a report. Make sure the report is detailed and contains any and all relevant information. expected_output: > A fully fledge reports with the mains topics, each with a full section of information. Formatted as markdown without '

Q: Is CrewAI suitable for production environments?

A: Yes, CrewAI is explicitly designed with production-grade standards, ensuring reliability, stability, and scalability for enterprise deployments.

Q: Can CrewAI agents interact with external tools and APIs?

A: Absolutely! CrewAI agents can easily integrate with external tools, APIs, and databases, empowering them to leverage real-world data and resources.

Q: Can CrewAI automate human-in-the-loop workflows?

A: Yes, CrewAI fully supports human-in-the-loop workflows, allowing seamless collaboration between human experts and AI agents for enhanced decision-making.

How CrewAI Compares

CrewAI's Advantage: CrewAI combines autonomous agent intelligence with precise workflow control through its unique Crews and Flows architecture. The framework excels at both high-level orchestration and low-level customization, enabling complex, production-grade systems with granular control.

• LangGraph: While LangGraph provides a foundation for building agent workflows, its approach requires significant boilerplate code and complex state management patterns. The framework's tight coupling with LangChain can limit flexibility when implementing custom agent behaviors or integrating with external systems.

_P.S. CrewAI demonstrates significant performance advantages over LangGraph, executing 5.76x faster in certain cases like this QA task example (see comparison) while achieving higher evaluation scores with faster completion times in certain coding tasks, like in this example (detailed analysis).

• Autogen: While Autogen excels at creating conversational agents capable of working together, it lacks an inherent concept of process. In Autogen, orchestrating agents' interactions requires additional programming, which can become complex and cumbersome as the scale of tasks grows.
• ChatDev: ChatDev introduced the idea of processes into the realm of AI agents, but its implementation is quite rigid. Customizations in ChatDev are limited and not geared towards production environments, which can hinder scalability and flexibility in real-world applications.

Troubleshooting Dependencies

If you encounter issues during installation or usage, here are some common solutions:

Common Issues

1. ModuleNotFoundError: No module named 'tiktoken'

• Install tiktoken explicitly: uv pip install 'crewai[embeddings]'
• If using embedchain or other tools: uv pip install 'crewai[tools]'

1. Failed building wheel for tiktoken

• Ensure Rust compiler is installed (see installation steps above)
• For Windows: Verify Visual C++ Build Tools are installed
• Try upgrading pip: uv pip install --upgrade pip
• If issues persist, use a pre-built wheel: uv pip install tiktoken --prefer-binary
