CrewAI Skills

A collection of skills for AI coding agents that teach best practices for building with CrewAI. Skills follow the Agent Skills format.

Available Skills

getting-started

CrewAI architecture decisions and project scaffolding. Covers choosing the right abstraction (LLM.call() vs Agent.kickoff() vs Crew.kickoff() vs Flow), CLI scaffolding, YAML configuration, wiring @CrewBase crews, writing Flows with @start/@listen, and variable interpolation.

Use when:

• Starting a new CrewAI project
• Choosing between abstraction levels
• Scaffolding with crewai create flow
• Setting up agents.yaml and tasks.yaml
• Wiring crew.py or main.py
• Debugging common setup issues

design-agent

CrewAI agent design and configuration. Covers the Role-Goal-Backstory framework, LLM selection, tool assignment, execution tuning (max_iter, max_rpm, max_execution_time), memory and knowledge sources, guardrails, and YAML vs code configuration.

Use when:

• Creating or configuring CrewAI agents
• Choosing role, goal, and backstory
• Assigning tools or selecting LLMs
• Tuning agent parameters
• Setting up knowledge sources or memory
• Debugging agent behavior

design-task

CrewAI task design and configuration. Covers writing effective descriptions and expected output, task dependencies with context, structured output (output_pydantic, output_json, output_file), guardrails, human-in-the-loop review, and async execution.

Use when:

• Creating or configuring CrewAI tasks
• Writing task descriptions and expected output
• Setting up task dependencies
• Configuring structured output formats
• Adding guardrails or human review
• Debugging task execution issues

Installation

In Claude Code, add this marketplace and install the plugin:

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

The first command registers the marketplace from this repo's .claude-plugin/marketplace.json. The second installs the crewai-skills plugin from the crewai-plugins marketplace.

To pin to a specific branch or tag:

/plugin marketplace add crewAIInc/skills

Skill Structure

Each skill contains:

• SKILL.md - Instructions for the agent
• references/ - Supporting documentation (tools catalog, MCP servers, structured output patterns, etc.)
