AGDebugger is an interactive system to help you debug your agent teams. It offers interactions to:

1. Send and step through agent messages
2. Edit previously sent agent messages and revert to earlier points in a conversation
3. Navigate agent conversations with an interactive visualization

You can install AGDebugger locally by cloning the repo and installing the python package.

# Install & build frontend
cd frontend
npm install
npm run build
# Install & build agdebugger python package
cd ..
pip install .

AGDebugger is built on top of AutoGen. To use AGDebugger, you provide a python file that exposes a function that creates an AutoGen AgentChat team for debugging. You can then launch AgDebugger with this agent team.

For example, the script below creates a simple agent team with a single WebSurfer agent.

# scenario.py
from autogen_agentchat.teams import MagenticOneGroupChat
from autogen_agentchat.ui import Console
from autogen_ext.agents.web_surfer import MultimodalWebSurfer
from autogen_ext.models.openai import OpenAIChatCompletionClient

async def get_agent_team():
    model_client = OpenAIChatCompletionClient(model="gpt-4o")

    surfer = MultimodalWebSurfer(
        "WebSurfer",
        model_client=model_client,
    )
    team = MagenticOneGroupChat([surfer], model_client=model_client)

    return team

We can then launch the interface with:

 agdebugger scenario:get_agent_team

Once in the interface, you can send a GroupChatStart message to the start the agent conversation and begin debugging!
