Multi-agent handoff

A run can span a handoff chain — one agent delegating to another mid-run. Both event types carry agent (which agent produced the event), so multi-agent output stays attributable. Label the stream by the agent in control:

from cosmon_agent_sdk import Client, TextChunk

with Client() as client:
    speaker = ""
    for event in client.run("Set up the model, then hand off to COMSOL to solve it", agent="solidworks"):
        if event.agent and event.agent != speaker:   # who's talking now
            speaker = event.agent
            print(f"\n[{speaker}]")
        if isinstance(event, TextChunk):
            print(event.text, end="", flush=True)

In a session, later turns follow the agent in control — so a handoff carries into the next turn, the same as in the app. .text(live=True) prints these [agent] labels for you.
