Hierarchical Agent Teams¶
In our previous example (Agent Supervisor), we introduced the concept of a single supervisor node to route work between different worker nodes.
But what if the job for a single worker becomes too complex? What if the number of workers becomes too large?
For some applications, the system may be more effective if work is distributed hierarchically.
You can do this by composing different subgraphs and creating a top-level supervisor, along with mid-level supervisors.
To do this, let's build a simple research assistant! The graph will look something like the following:
This notebook is inspired by the paper AutoGen: Enabling Next-Gen LLM Applications via Multi-Agent Conversation, by Wu, et. al. In the rest of this notebook, you will:
- Define the agents' tools to access the web and write files
- Define some utilities to help create the graph and agents
- Create and define each team (web research + doc writing)
- Compose everything together.
Setup¶
First, let's install our required packages and set our API keys
%%capture --no-stderr
%pip install -U langgraph langchain langchain_openai 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("OPENAI_API_KEY")
_set_if_undefined("TAVILY_API_KEY")
Create Tools¶
Each team will be composed of one or more agents each with one or more tools. Below, define all the tools to be used by your different teams.
We'll start with the research team.
ResearchTeam tools
The research team can use a search engine and url scraper to find information on the web. Feel free to add additional functionality below to boost the team performance!
from typing import Annotated, List
from langchain_community.document_loaders import WebBaseLoader
from langchain_community.tools.tavily_search import TavilySearchResults
from langchain_core.tools import tool
tavily_tool = TavilySearchResults(max_results=5)
@tool
def scrape_webpages(urls: List[str]) -> str:
"""Use requests and bs4 to scrape the provided web pages for detailed information."""
loader = WebBaseLoader(urls)
docs = loader.load()
return "\n\n".join(
[
f'<Document name="{doc.metadata.get("title", "")}">\n{doc.page_content}\n</Document>'
for doc in docs
]
)
Document writing team tools
Next up, we will give some tools for the doc writing team to use. We define some bare-bones file-access tools below.
Note that this gives the agents access to your file-system, which can be unsafe. We also haven't optimized the tool descriptions for performance.
from pathlib import Path
from tempfile import TemporaryDirectory
from typing import Dict, Optional
from langchain_experimental.utilities import PythonREPL
from typing_extensions import TypedDict
_TEMP_DIRECTORY = TemporaryDirectory()
WORKING_DIRECTORY = Path(_TEMP_DIRECTORY.name)
@tool
def create_outline(
points: Annotated[List[str], "List of main points or sections."],
file_name: Annotated[str, "File path to save the outline."],
) -> Annotated[str, "Path of the saved outline file."]:
"""Create and save an outline."""
with (WORKING_DIRECTORY / file_name).open("w") as file:

return f"Outline saved to {file_name}"
@tool

) -> str:

if start is not None:

return "\n".join(lines[start:end])
@tool
def write_document(

file_name: Annotated[str, "File path to save the document."],
) -> Annotated[str, "Path of the saved document file."]:

],
) -> Annotated[str, "Path of the edited document file."]:
"""Edit a document by inserting text at specific line numbers."""
with (WORKING_DIRECTORY / file_name).open("r") as file:
lines = file.readlines()
sorted_inserts = sorted(inserts.items())
for line_number, text in sorted_inserts:
if 1 <= line_number <= len(lines) + 1:
lines.insert(line_number - 1, text + "\n")
else:
return f"Error: Line number {line_number} is out of range."
with (WORKING_DIRECTORY / file_name).open("w") as file:
file.writelines(lines)
return f"Document edited and saved to {file_name}"
# Warning: This executes code locally, which can be unsafe when not sandboxed
repl = PythonREPL()
@tool
def python_repl(
code: Annotated[str, "The python code to execute to generate your chart."],
):
"""Use this to execute python code. 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)}"
return f"Successfully executed:\n```python\n{code}\n```\nStdout: {result}"
Helper Utilities¶
We are going to create a few utility functions to make it more concise when we want to:
- Create a worker agent.
- Create a supervisor for the sub-graph.
These will simplify the graph compositional code at the end for us so it's easier to see what's going on.

" 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.",
["Search", "WebScraper"],
)
Now that we've created the necessary components, defining their interactions is easy. Add the nodes to the team graph, and define the edges, which determine the transition criteria.
research_graph = StateGraph(ResearchTeamState)
research_graph.add_node("Search", search_node)
research_graph.add_node("WebScraper", research_node)

research_graph.add_conditional_edges(
"supervisor",
lambda x: x["next"],
{"Search": "Search", "WebScraper": "WebScraper", "FINISH": END},
)
research_graph.add_edge(START, "supervisor")
chain = research_graph.compile()
# The following functions interoperate between the top level graph state
# and the state of the research sub-graph
# this makes it so that the states of each graph don't get intermixed
def enter_chain(message: str):

"messages": [HumanMessage(content=message)],
}
return results
research_chain = enter_chain | chain
from IPython.display import Image, display
display(Image(chain.get_graph(xray=True).draw_mermaid_png()))
We can give this team work directly. Try it out below.
for s in research_chain.stream(
"when is Taylor Swift's next tour?", {"recursion_limit": 100}
):
if "__end__" not in s:
print(s)
print("---")

Document Writing Team¶
Create the document writing team below using a similar approach. This time, we will give each agent access to different file-writing tools.
Note that we are giving file-system access to our agent here, which is not safe in all cases.

["DocWriter", "NoteTaker", "ChartGenerator"],
)
With the objects themselves created, we can form the graph.
# Create the graph here:
# Note that we have unrolled the loop for the sake of this doc
authoring_graph = StateGraph(DocWritingState)
authoring_graph.add_node("DocWriter", doc_writing_node)

return results
# We reuse the enter/exit functions to wrap the graph

Add Layers¶
In this design, we are enforcing a top-down planning policy. We've created two graphs already, but we have to decide how to route work between the two.
We'll create a third graph to orchestrate the previous two, and add some connectors to define how this top-level state is shared between the different graphs.
