* [BREAKING] Rename ChatAgent -> Agent, ChatMessage -> Message, ChatClientProtocol -> SupportsChatGetResponse Simplify the public API by removing redundant 'Chat' prefix from core types: - ChatAgent -> Agent - RawChatAgent -> RawAgent - ChatMessage -> Message - ChatClientProtocol -> SupportsChatGetResponse Also renamed internal WorkflowMessage (was Message in _runner_context) to avoid collision. No backward compatibility aliases - this is a clean breaking change. * [BREAKING] Rename Agent chat_client parameter to client * Fix rebase issues: WorkflowMessage references and broken markdown links * Fix formatting and lint issues from code quality checks * Fix import ordering in workflow sample files * fixed rebase * Fix test failures: use WorkflowMessage and A2AMessage after ChatMessage→Message rename - Replace Message(data=..., source_id=...) with WorkflowMessage(...) in workflow tests - Fix isinstance check in A2A agent to use A2AMessage instead of Message - Fix import in test_workflow_observability.py (Message→WorkflowMessage) * Fix lint, fmt, and sample errors after ChatMessage→Message rename - Auto-fix 70+ ruff lint issues across samples (ChatMessage→Message refs) - Fix HostedVectorStoreContent→Content.from_hosted_vector_store in file search sample - Fix _normalize_messages→normalize_messages in custom agent sample - Fix context.terminate→raise MiddlewareTermination in middleware samples - Fix with_update_hook→with_transform_hook in override middleware sample - Add TOptions_co import back to custom_chat_client sample - Add noqa for FastAPI File() default in chatkit sample - Fix B023 loop variable capture in weather agent sample * fix: update Agent constructor calls from chat_client to client in declaration-only tool tests * fix: add register_cleanup to devui lazy-loading proxy and type stub * fixed tests and updated new pieces * fix agui typevar * fix merge errors * fix merge conflicts * fiux merge * Remove unused links --------- Co-authored-by: Evan Mattson <evan.mattson@microsoft.com>

Multi-Agent
This sample demonstrates how to host multiple AI agents with different tools in a single worker-client setup using the Durable Task Scheduler.
Key Concepts Demonstrated
- Hosting multiple agents (WeatherAgent and MathAgent) in a single worker process.
- Each agent with its own specialized tools and instructions.
- Interacting with different agents using separate conversation threads.
- Worker-client architecture for multi-agent systems.
Environment Setup
See the README.md file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
Running the Sample
With the environment setup, you can run the sample using the combined approach or separate worker and client processes:
Option 1: Combined (Recommended for Testing)
cd samples/getting_started/durabletask/02_multi_agent
python sample.py
Option 2: Separate Processes
Start the worker in one terminal:
python worker.py
In a new terminal, run the client:
python client.py
The client will interact with both agents:
Starting Durable Task Multi-Agent Client...
Using taskhub: default
Using endpoint: http://localhost:8080
================================================================================
Testing WeatherAgent
================================================================================
Created weather conversation thread: <guid>
User: What is the weather in Seattle?
🔧 [TOOL CALLED] get_weather(location=Seattle)
✓ [TOOL RESULT] {'location': 'Seattle', 'temperature': 72, 'conditions': 'Sunny', 'humidity': 45}
WeatherAgent: The current weather in Seattle is sunny with a temperature of 72°F and 45% humidity.
================================================================================
Testing MathAgent
================================================================================
Created math conversation thread: <guid>
User: Calculate a 20% tip on a $50 bill
🔧 [TOOL CALLED] calculate_tip(bill_amount=50.0, tip_percentage=20.0)
✓ [TOOL RESULT] {'bill_amount': 50.0, 'tip_percentage': 20.0, 'tip_amount': 10.0, 'total': 60.0}
MathAgent: For a $50 bill with a 20% tip, the tip amount is $10.00 and the total is $60.00.
Viewing Agent State
You can view the state of both agents in the Durable Task Scheduler dashboard:
- Open your browser and navigate to
http://localhost:8082 - In the dashboard, you can view:
- The state of both WeatherAgent and MathAgent entities (dafx-WeatherAgent, dafx-MathAgent)
- Each agent's conversation state across multiple interactions
