Python: Need a handoffbuilder workflow as a agent example

[HelloHaiGG]

Can you provide a demo of how to use HandoffBuilder to create a workflow where an agent processes user input requests?

For example：

workflow = (

HandoffBuilder(

name="customer_support_handoff",

participants=[summary_agent, doc_agent, contact_agent, mail_agent],

)

.set_coordinator("meeting_summary_agent")

.enable_return_to_previous(True)

.build()

)


agent = workflow.as_agent()



    while True:
        print(" user: ",user)
        
        async for chunk in agent.run_stream(
            messages=user,
            thread=thread,
        ):  

            ...

Additional question: When interacting via an agent, how to pass the results of the human-computer interaction to the context?

@HelloHaiGG we have many handoff samples in this directory: https://github.com/microsoft/agent-framework/tree/main/python/samples/getting_started/workflows/orchestration

And one showing a Handoff + checkpointing + HITL: https://github.com/microsoft/agent-framework/blob/main/python/samples/getting_started/workflows/checkpoint/handoff_with_tool_approval_checkpoint_resume.py

Have you had a look at those? If so, is something unclear? The handoff pattern right now always goes back to the human for further input.

Yes, I've reviewed these documents, but they don't solve my problem. My actual issue is:

Custom messages cannot be directly returned in WorkflowAgent mode.

Using the workflow directly, I can pass custom information to the context like this:

await workflow.send_responses_streaming(responses)

If I use workflowagent=workflow.as_agent()

How should I create a custom response for HandoffUserInputRequest?

Hi @HelloHaiGG, I have added a sample in the following PR #2534 showing how to handle this.

PERFECT! Thank you!
