Thanks — great question. You're asking whether

shutdown_callback

runs after

AgentSession.aclose()

or after the room is deleted. Here's the concise answer and what that means for cleanup logic. Answer •

shutdown_callback

runs after the

AgentSession

is closed with

await session.aclose()

. • Room deletion (for example via the LiveKit API

delete_room

) is a separate step and happens after the session has been closed and the shutdown callbacks have run. What this means • Call

aclose()

to end the agent session and disconnect I/O. • Any functions you register with

ctx.add_shutdown_callback()

will execute during the session’s post-shutdown processing immediately after

aclose()

completes. • If you delete the room separately, do that only after your shutdown callbacks finish (for example, in a post-callback step). Shutdown callbacks are the right place for final cleanup such as saving state or logging. Timeout note • Shutdown callbacks should finish promptly — they run during the session shutdown window (there is a default timeout for shutdown processing). If you want, tell me how you’re currently using

shutdown_callback

(what cleanup it performs) and whether you delete rooms automatically or manually — I can suggest where to place room-deletion calls safely and an example ordering. Sources: Job lifecycle | LiveKit Documentation
