使用智能体作为工具的多智能体报告生成系统¶

在本笔记本中，我们将探索如何创建一个多智能体系统，该系统使用顶层智能体来协调一组作为工具使用的子智能体。具体而言，我们将构建一个能够研究、撰写并评审给定主题报告的系统。

本笔记本假设您已经阅读过基础智能体工作流程笔记本或通用智能体文档。

安装配置¶

在本示例中，我们将使用 OpenAI 作为我们的 LLM（大语言模型）。如需了解所有支持的 LLM 及其安装使用方法，请查阅 示例文档 或访问 LlamaHub 查看完整列表。

虽然每个智能体都可以配置不同的 LLM，但为了简化演示，本示例中所有智能体将使用相同的 LLM。

from llama_index.llms.openai import OpenAI

sub_agent_llm = OpenAI(model="gpt-4.1-mini", api_key="sk-...")
orchestrator_llm = OpenAI(model="o3-mini", api_key="sk-...")

from llama_index.llms.openai import OpenAI sub_agent_llm = OpenAI(model="gpt-4.1-mini", api_key="sk-...") orchestrator_llm = OpenAI(model="o3-mini", api_key="sk-...")

系统设计¶

我们的系统将包含三个智能体：

1. ResearchAgent：负责在网络上搜索与给定主题相关的信息。
2. WriteAgent：利用ResearchAgent找到的信息撰写报告。
3. ReviewAgent：负责审阅报告并提供反馈意见。

我们将使用一个顶层智能体来协调其他智能体共同完成报告撰写工作。

虽然实现这个系统有多种方式，但在本案例中，我们将使用单一的web_search工具来搜索与主题相关的网络信息。

from tavily import AsyncTavilyClient


async def search_web(query: str) -> str:
    """Useful for using the web to answer questions."""
    client = AsyncTavilyClient(api_key="tvly-...")
    return str(await client.search(query))

from tavily import AsyncTavilyClient async def search_web(query: str) -> str: """Useful for using the web to answer questions.""" client = AsyncTavilyClient(api_key="tvly-...") return str(await client.search(query))

定义好工具后，我们现在可以创建子代理。

如果使用的LLM支持工具调用功能，可以使用FunctionAgent类；否则，可以使用ReActAgent类。

In [ ]:

from llama_index.core.agent.workflow import FunctionAgent, ReActAgent

research_agent = FunctionAgent(
    system_prompt=(
        "You are the ResearchAgent that can search the web for information on a given topic and record notes on the topic. "
        "You should output notes on the topic in a structured format."
    ),
    llm=sub_agent_llm,
    tools=[search_web],
)

write_agent = FunctionAgent(
    system_prompt=(
        "You are the WriteAgent that can write a report on a given topic. "
        "Your report should be in a markdown format. The content should be grounded in the research notes. "
        "Return your markdown report surrounded by <report>...</report> tags."
    ),
    llm=sub_agent_llm,
    tools=[],
)

review_agent = FunctionAgent(
    system_prompt=(
        "You are the ReviewAgent that can review the write report and provide feedback. "
        "Your review should either approve the current report or request changes to be implemented."
    ),
    llm=sub_agent_llm,
    tools=[],
)

from llama_index.core.agent.workflow import FunctionAgent, ReActAgent research_agent = FunctionAgent( system_prompt=( "You are the ResearchAgent that can search the web for information on a given topic and record notes on the topic. " "You should output notes on the topic in a structured format." ), llm=sub_agent_llm, tools=[search_web], ) write_agent = FunctionAgent( system_prompt=( "You are the WriteAgent that can write a report on a given topic. " "Your report should be in a markdown format. The content should be grounded in the research notes. " "Return your markdown report surrounded by ... tags." ), llm=sub_agent_llm, tools=[], ) review_agent = FunctionAgent( system_prompt=( "You are the ReviewAgent that can review the write report and provide feedback. " "Your review should either approve the current report or request changes to be implemented." ), llm=sub_agent_llm, tools=[], )

在我们定义好子代理后，就可以将它们转换为可供顶层代理使用的工具。
