CrewAI Agent 框架

Python 原生多 Agent 协作框架——让多个 AI Agent 像团队一样工作。

功能介绍

CrewAI 是目前最流行的多 Agent 协作框架之一，核心理念是「角色化 Agent + 结构化流程」。

核心概念：

• Agent：定义角色、目标、背景故事和可用工具
• Task：定义具体任务、预期输出和负责 Agent
• Crew：编排多个 Agent 和 Task 的执行流程
• Process：顺序执行（Sequential）或层级管理（Hierarchical）
• Memory：短期记忆、长期记忆和实体记忆
• Tools：集成 LangChain Tools、自定义函数

安装步骤

pip install crewai
pip install 'crewai[tools]'  # 含额外工具集成

使用示例

from crewai import Agent, Task, Crew, Process

researcher = Agent(
    role='Researcher',
    goal='Find and analyze information',
    backstory='Expert at gathering and synthesizing data',
    tools=[search_tool, web_scraper]
)

writer = Agent(
    role='Writer',
    goal='Create compelling content',
    backstory='Skilled at turning research into narratives'
)

research_task = Task(description='Research AI trends in 2026', agent=researcher)
write_task = Task(description='Write a blog post based on research', agent=writer)

crew = Crew(
    agents=[researcher, writer],
    tasks=[research_task, write_task],
    process=Process.sequential
)

result = crew.kickoff()
