CrewAI

Multi-agent orchestration framework for autonomous AI collaboration. Use when building teams of specialized agents working together on complex tasks, when you need role-based agent collaboration with memory, or for production workflows requiring sequential/hierarchical execution. Built without LangChain dependencies for lean, fast execution.

This skill should be used when designing CrewAI Flows with typed state management, deterministic routing, and event-driven orchestration. Use it for flow architecture, state transitions, control primitives, and production deployment.

This skill should be used when selecting CrewAI built-in tools, composing agent toolchains, or creating production-ready custom tools with BaseTool or @tool, including schema validation, dependency management, caching, async support, and testing.

This skill should be used when designing CrewAI crews with YAML-first architecture. Use it to create crews, configure agents and tasks, select processes, and generate validation-ready outputs.
