Multi-agent supervisor¶
The previous example routed messages automatically based on the output of the initial researcher agent.
We can also choose to use an LLM to orchestrate the different agents.
Below, we will create an agent group, with an agent supervisor to help delegate tasks.
To simplify the code in each agent node, we will use LangGraph's prebuilt create_react_agent. This and other "advanced agent" notebooks are designed to show how you can implement certain design patterns in LangGraph. If the pattern suits your needs, we recommend combining it with some of the other fundamental patterns described elsewhere in the docs for best performance.
Setup¶
First, let's install required packages and set our API keys
%%capture --no-stderr
%pip install -U langgraph langchain_community langchain_anthropic langchain_experimental
import getpass
import os
def _set_if_undefined(var: str):
if not os.environ.get(var):
os.environ[var] = getpass.getpass(f"Please provide your {var}")
_set_if_undefined("ANTHROPIC_API_KEY")
_set_if_undefined("TAVILY_API_KEY")
Set up LangSmith for LangGraph development
Sign up for LangSmith to quickly spot issues and improve the performance of your LangGraph projects. LangSmith lets you use trace data to debug, test, and monitor your LLM apps built with LangGraph — read more about how to get started here.
Create tools¶
For this example, you will make an agent to do web research with a search engine, and one agent to create plots. Define the tools they'll use below:
from typing import Annotated
from langchain_community.tools.tavily_search import TavilySearchResults
from langchain_core.tools import tool
from langchain_experimental.utilities import PythonREPL
tavily_tool = TavilySearchResults(max_results=5)
# This executes code locally, which can be unsafe
repl = PythonREPL()
@tool
def python_repl_tool(
code: Annotated[str, "The python code to execute to generate your chart."],
):
"""Use this to execute python code and do math. If you want to see the output of a value,
you should print it out with `print(...)`. This is visible to the user."""
try:
result = repl.run(code)
except BaseException as e:
return f"Failed to execute. Error: {repr(e)}"
result_str = f"Successfully executed:\n\`\`\`python\n{code}\n\`\`\`\nStdout: {result}"
return result_str
Create Agent Supervisor¶
It will use LLM with structured output to choose the next worker node OR finish processing.
# The agent state is the input to each node in the graph
class AgentState(MessagesState):
# The 'next' field indicates where to route to next
next: str
from typing import Literal
from typing_extensions import TypedDict
from langchain_anthropic import ChatAnthropic
members = ["researcher", "coder"]
# Our team supervisor is an LLM node. It just picks the next agent to process
# and decides when the work is completed
options = members + ["FINISH"]
system_prompt = (
"You are a supervisor tasked with managing a conversation between the"
f" following workers: {members}. Given the following user request,"
" respond with the worker to act next. Each worker will perform a"
" task and respond with their results and status. When finished,"
" respond with FINISH."
)
class Router(TypedDict):
"""Worker to route to next. If no workers needed, route to FINISH."""
next: Literal[*options]
llm = ChatAnthropic(model="claude-3-5-sonnet-latest")
def supervisor_node(state: AgentState) -> AgentState:
messages = [
{"role": "system", "content": system_prompt},
] + state["messages"]
response = llm.with_structured_output(Router).invoke(messages)
next_ = response["next"]
if next_ == "FINISH":
next_ = END
return {"next": next_}
API Reference:
ChatAnthropic
Construct Graph¶
We're ready to start building the graph. Below, define the state and worker nodes using the function we just defined.
from langchain_core.messages import HumanMessage
from langgraph.graph import StateGraph, START, END
from langgraph.prebuilt import create_react_agent
research_agent = create_react_agent(
llm, tools=[tavily_tool], state_modifier="You are a researcher. DO NOT do any math."
)
def research_node(state: AgentState) -> AgentState:
result = research_agent.invoke(state)
return {
"messages": [
HumanMessage(content=result["messages"][-1].content, name="researcher")
]
}
# NOTE: THIS PERFORMS ARBITRARY CODE EXECUTION, WHICH CAN BE UNSAFE WHEN NOT SANDBOXED
code_agent = create_react_agent(llm, tools=[python_repl_tool])
def code_node(state: AgentState) -> AgentState:
result = code_agent.invoke(state)
return {
"messages": [HumanMessage(content=result["messages"][-1].content, name="coder")]
}
builder = StateGraph(AgentState)
builder.add_edge(START, "supervisor")
builder.add_node("supervisor", supervisor_node)
builder.add_node("researcher", research_node)
builder.add_node("coder", code_node)
Now connect all the edges in the graph.
for member in members:
# We want our workers to ALWAYS "report back" to the supervisor when done
builder.add_edge(member, "supervisor")
# The supervisor populates the "next" field in the graph state
# which routes to a node or finishes
builder.add_conditional_edges("supervisor", lambda state: state["next"])
# Finally, add entrypoint
builder.add_edge(START, "supervisor")
graph = builder.compile()
Invoke the team¶
With the graph created, we can now invoke it and see how it performs!
for s in graph.stream(
{"messages": [("user", "What's the square root of 42?")]}, subgraphs=True
):
print(s)
print("----")
((), {'supervisor': {'next': 'coder'}})
