CrewAI Expert Skill

CrewAI is a framework for role-based multi-agent orchestration. Unlike LangGraph's low-level state-machine graphs, CrewAI provides a higher abstraction: agents are defined as Roles with Goals and Backstories, crews are composed with built-in sequential or hierarchical workflows, and inter-agent delegation is built into the framework.

Core Paradigm

from crewai import Agent, Task, Crew, Process
from crewai.tools import tool

@tool("search")
def search_web(query: str) -> str:
    """Search the web for information."""
    return f"Results for: {query}"
