AutoGen Multi-Agent Development
You are an expert in Microsoft AutoGen, a framework for building multi-agent AI systems with Python, focusing on agent orchestration, tool integration, and scalable AI applications.
Key Principles
- Write concise, technical responses with accurate Python examples
- Use async/await patterns for agent communication
- Implement proper error handling and logging
- Follow event-driven architecture patterns
- Use type hints for all function signatures
Setup and Installation
Environment Setup
# Install AutoGen
# pip install autogen-agentchat autogen-ext
from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.teams import RoundRobinGroupChat
from autogen_ext.models.openai import OpenAIChatCompletionClient
### Model Configuration
import os
Configure the model client
model_client = OpenAIChatCompletionClient(
model="gpt-4o",
api_key=os.environ.get("OPENAI_API_KEY")
)
## Core Concepts
### Agent Types
AutoGen provides several agent types:
- **AssistantAgent**: AI-powered agent for conversations and task completion
- **UserProxyAgent**: Represents human users, can execute code
- **GroupChat**: Orchestrates multi-agent conversations
- **ConversableAgent**: Base class for custom agents
## Creating Agents
### Basic Assistant Agent
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
model_client = OpenAIChatCompletionClient(model="gpt-4o")
assistant = AssistantAgent(
name="assistant",
model_client=model_client,
system_message="""You are a helpful AI assistant.
Provide clear, concise responses.
Ask clarifying questions when needed."""
)
### Agent with Tools
from autogen_agentchat.agents import AssistantAgent
from autogen_core.tools import FunctionTool
def search_database(query: str) -> str:
"""Search the database for information.
Args:
query: The search query string
Returns:
Search results as a string
"""
# Implementation
return f"Results for: {query}"
def calculate(expression: str) -> str:
"""Evaluate a mathematical expression.
Args:
expression: Mathematical expression to evaluate
Returns:
The result of the calculation
"""
try:
result = eval(expression)
return str(result)
except Exception as e:
return f"Error: {str(e)}"
Create tools
search_tool = FunctionTool(search_database, description="Search the database")
calc_tool = FunctionTool(calculate, description="Perform calculations")
Create agent with tools
agent = AssistantAgent(
name="tool_agent",
model_client=model_client,
tools=[search_tool, calc_tool],
system_message="You are an assistant with access to search and calculation tools."
)
## Multi-Agent Conversations
### Two-Agent Chat
from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.conditions import TextMentionTermination
from autogen_agentchat.teams import RoundRobinGroupChat
Create agents
researcher = AssistantAgent(
name="researcher",
model_client=model_client,
system_message="You are a research assistant. Gather and analyze information."
)
writer = AssistantAgent(
name="writer",
model_client=model_client,
system_message="You are a technical writer. Create clear documentation."
)
Create termination condition
termination = TextMentionTermination("TASK_COMPLETE")
Create group chat
team = RoundRobinGroupChat(
[researcher, writer],
termination_condition=termination
)
Run the conversation
async def run_team():
result = await team.run(task="Research and document Python best practices")
return result
### Group Chat with Multiple Agents
from autogen_agentchat.teams import SelectorGroupChat
from autogen_agentchat.conditions import MaxMessageTermination
Create specialized agents
planner = AssistantAgent(
name="planner",
model_client=model_client,
system_message="You are a project planner. Break down tasks and create plans."
)
coder = AssistantAgent(
name="coder",
model_client=model_client,
system_message="You are a software developer. Write clean, efficient code."
)
reviewer = AssistantAgent(
name="reviewer",
model_client=model_client,
system_message="You are a code reviewer. Review code for quality and best practices."
)
Selector-based group chat
team = SelectorGroupChat(
[planner, coder, reviewer],
model_client=model_client,
termination_condition=MaxMessageTermination(20)
)
## Code Execution
### Setting Up Code Execution
from autogen_ext.code_executors.local import LocalCommandLineCodeExecutor
from autogen_agentchat.agents import AssistantAgent
Create code executor
code_executor = LocalCommandLineCodeExecutor(
work_dir="./workspace",
timeout=60
)
Agent that can execute code
coding_agent = AssistantAgent(
name="coder",
model_client=model_client,
code_executor=code_executor,
system_message="""You are a Python developer.
Write code to solve problems.
Test your code before providing final answers."""
)
### Docker-Based Execution
from autogen_ext.code_executors.docker import DockerCommandLineCodeExecutor
Secure code execution in Docker
docker_executor = DockerCommandLineCodeExecutor(
image="python:3.11-slim",
timeout=120,
work_dir="./workspace"
)
## Conversation Patterns
### Sequential Workflow
from autogen_agentchat.teams import Swarm
from autogen_agentchat.agents import AssistantAgent
Define agents for each step
analyst = AssistantAgent(
name="analyst",
model_client=model_client,
handoffs=["developer"],
system_message="Analyze requirements and hand off to developer."
)
developer = AssistantAgent(
name="developer",
model_client=model_client,
handoffs=["tester"],
system_message="Implement the solution and hand off to tester."
)
tester = AssistantAgent(
name="tester",
model_client=model_client,
system_message="Test the implementation and report results."
)
Create swarm for handoff-based workflow
team = Swarm([analyst, developer, tester])
### Hierarchical Structure
Manager agent that coordinates others
manager = AssistantAgent(
name="manager",
model_client=model_client,
system_message="""You are a project manager.
Coordinate between team members.
Delegate tasks appropriately.
Synthesize results into final deliverables."""
)
Worker agents
workers = [
AssistantAgent(name="researcher", model_client=model_client, ...),
AssistantAgent(name="analyst", model_client=model_client, ...),
AssistantAgent(name="writer", model_client=model_client, ...)
]
## Memory and State
### Conversation Memory
from autogen_agentchat.messages import TextMessage
Agents maintain conversation history automatically
Access through the team's message history
async def run_with_memory():
result = await team.run(task="Initial task")
# Continue with context
result = await team.run(task="Follow-up question")
# Access message history
for message in result.messages:
print(f"{message.source}: {message.content}")
## Event-Driven Architecture
### Custom Event Handling
from autogen_core import Event
Subscribe to events
async def on_message_received(event: Event):
print(f"Message received: {event.data}")
Events enable reactive patterns
- Agent activation
- Tool execution
- Error handling
- State changes
## Error Handling
### Robust Agent Design
from autogen_agentchat.agents import AssistantAgent
import logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)
async def safe_run_team(team, task: str, max_retries: int = 3):
"""Run team with error handling and retries."""
for attempt in range(max_retries):
try:
result = await team.run(task=task)
return result
except Exception as e:
logger.error(f"Attempt {attempt + 1} failed: {e}")
if attempt == max_retries - 1:
raise
return None
## Best Practices
### Agent Design
- Give agents clear, focused responsibilities
- Use descriptive system messages
- Implement proper tool descriptions
- Set appropriate termination conditions
- Use handoffs for complex workflows
### Performance
- Use async patterns for concurrent operations
- Implement caching for repeated queries
- Set reasonable timeouts
- Monitor token usage
- Use appropriate model sizes for each agent
### Security
- Never execute untrusted code directly
- Use Docker for code execution
- Validate tool inputs
- Implement rate limiting
- Log all agent actions
### Testing
- Unit test individual agents
- Integration test multi-agent workflows
- Test termination conditions
- Validate tool execution
- Monitor conversation quality
## Dependencies
- autogen-agentchat
- autogen-core
- autogen-ext
- openai (or other LLM providers)
- python-dotenv
- docker (for secure code execution)
