Multi-Agent Research Workflow with AgentWorkflow¶

In this notebook, we will explore how to use the AgentWorkflow class to create multi-agent systems. Specifically, we will create a system that can generate a report on a given topic.

This notebook will assume that you have already either read the basic agent workflow notebook or the agent workflow documentation.

Setup¶

In this example, we will use OpenAI as our LLM. For all LLMs, check out the examples documentation or LlamaHub for a list of all supported LLMs and how to install/use them.

If we wanted, each agent could have a different LLM, but for this example, we will use the same LLM for all agents.

In [ ]:

%pip install llama-index

%pip install llama-index

In [ ]:

from llama_index.llms.openai import OpenAI

llm = OpenAI(model="gpt-4o", api_key="sk-proj-...")

from llama_index.llms.openai import OpenAI llm = OpenAI(model="gpt-4o", api_key="sk-proj-...")

System Design¶

Our system will have three agents:

1. A ResearchAgent that will search the web for information on the given topic.
2. A WriteAgent that will write the report using the information found by the ResearchAgent.
3. A ReviewAgent that will review the report and provide feedback.

We will use the AgentWorkflow class to create a multi-agent system that will execute these agents in order.

While there are many ways to implement this system, in this case, we will use a few tools to help with the research and writing processes.

1. A web_search tool to search the web for information on the given topic.
2. A write_report tool to write the report using the information found by the ResearchAgent.
3. A review_report tool to review the report and provide feedback.

Utilizing the Context class, we can pass state between agents, and each agent will have access to the current state of the system.

%pip install tavily-python

%pip install tavily-python

from tavily import AsyncTavilyClient
from llama_index.core.workflow import Context


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))


async def record_notes(ctx: Context, notes: str, notes_title: str) -> str:
    """Useful for recording notes on a given topic."""
    current_state = await ctx.get("state")
    if "research_notes" not in current_state:
        current_state["research_notes"] = {}
    current_state["research_notes"][notes_title] = notes
    await ctx.set("state", current_state)
    return "Notes recorded."


async def write_report(ctx: Context, report_content: str) -> str:
    """Useful for writing a report on a given topic."""
    current_state = await ctx.get("state")
    current_state["report_content"] = report_content
    await ctx.set("state", current_state)
    return "Report written."


async def review_report(ctx: Context, review: str) -> str:
    """Useful for reviewing a report and providing feedback."""
    current_state = await ctx.get("state")
    current_state["review"] = review
    await ctx.set("state", current_state)
    return "Report reviewed."

from tavily import AsyncTavilyClient from llama_index.core.workflow import Context 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)) async def record_notes(ctx: Context, notes: str, notes_title: str) -> str: """Useful for recording notes on a given topic.""" current_state = await ctx.get("state") if "research_notes" not in current_state: current_state["research_notes"] = {} current_state["research_notes"][notes_title] = notes await ctx.set("state", current_state) return "Notes recorded." async def write_report(ctx: Context, report_content: str) -> str: """Useful for writing a report on a given topic.""" current_state = await ctx.get("state") current_state["report_content"] = report_content await ctx.set("state", current_state) return "Report written." async def review_report(ctx: Context, review: str) -> str: """Useful for reviewing a report and providing feedback.""" current_state = await ctx.get("state") current_state["review"] = review await ctx.set("state", current_state) return "Report reviewed."

With our tools defined, we can now create our agents.

If the LLM you are using supports tool calling, you can use the FunctionAgent class. Otherwise, you can use the ReActAgent class.

Here, the name and description of each agent is used so that the system knows what each agent is responsible for and when to hand off control to the next agent.

In [ ]:

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

research_agent = FunctionAgent(
    name="ResearchAgent",
    description="Useful for searching the web for information on a given topic and recording notes on the topic.",
    system_prompt=(
        "You are the ResearchAgent that can search the web for information on a given topic and record notes on the topic. "
        "Once notes are recorded and you are satisfied, you should hand off control to the WriteAgent to write a report on the topic."
    ),
    llm=llm,
    tools=[search_web],
    can_handoff_to=["WriteAgent"],
)

write_agent = FunctionAgent(
    name="WriteAgent",
    description="Useful for writing a report on a given topic.",
    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. "
        "Once the report is written, you should get feedback at least once from the ReviewAgent."
    ),
    llm=llm,
    tools=[write_report, record_notes],
    can_handoff_to=["ReviewAgent", "ResearchAgent"],
)

review_agent = FunctionAgent(
    name="ReviewAgent",
    description="Useful for reviewing a report and providing feedback.",
    system_prompt=(
        "You are the ReviewAgent that can review a report and provide feedback. "
        "Your feedback should either approve the current report or request changes for the WriteAgent to implement."
    ),
    llm=llm,
    tools=[review_report],
    can_handoff_to=["WriteAgent"],
)

from llama_index.core.agent.workflow import FunctionAgent, ReActAgent research_agent = FunctionAgent( name="ResearchAgent", description="Useful for searching the web for information on a given topic and recording notes on the topic.", system_prompt=( "You are the ResearchAgent that can search the web for information on a given topic and record notes on the topic.

" "Your report should be in a markdown format. The content should be grounded in the research notes. " "Once the report is written, you should get feedback at least once from the ReviewAgent." ), llm=llm, tools=[write_report, record_notes], can_handoff_to=["ReviewAgent", "ResearchAgent"], ) review_agent = FunctionAgent( name="ReviewAgent", description="Useful for reviewing a report and providing feedback.", system_prompt=( "You are the ReviewAgent that can review a report and provide feedback. " "Your feedback should either approve the current report or request changes for the WriteAgent to implement." ), llm=llm, tools=[review_report], can_handoff_to=["WriteAgent"], )

Running the Workflow¶

With our agents defined, we can create our AgentWorkflow and run it.

In [ ]:

from llama_index.core.agent.workflow import AgentWorkflow

agent_workflow = AgentWorkflow(
    agents=[research_agent, write_agent, review_agent],
    root_agent=write_agent.name,
    initial_state={
        "research_notes": {},
        "report_content": "Not written yet.",
        "review": "Review required.",
    },
)

from llama_index.core.agent.workflow import AgentWorkflow agent_workflow = AgentWorkflow( agents=[research_agent, write_agent, review_agent], root_agent=write_agent.name, initial_state={ "research_notes": {}, "report_content": "Not written yet.", "review": "Review required.", }, )

As the workflow is running, we will stream the events to get an idea of what is happening under the hood.

In [ ]:

from llama_index.core.agent.workflow import (
    AgentInput,
    AgentOutput,
    ToolCall,
    ToolCallResult,
