Is it possible to have multiple assistants respond in the same thread? I want to build a multi-agent system where:

1. Assistant A (researcher) searches files 2. Assistant B (writer) uses the research to draft content 3. Assistant C (editor) reviews and polishes

All working on the same thread so they can see each other's outputs.

# Create thread
thread = client.beta.threads.create()
Run assistant A
run_a = client.beta.threads.runs.create_and_poll(
    thread_id=thread.id,
    assistant_id=researcher_id
)
Run assistant B on same thread
run_b = client.beta.threads.runs.create_and_poll(
    thread_id=thread.id,
    assistant_id=writer_id  # Can this see A's output?
)

Does this work? Are there better patterns for multi-agent workflows?
