03/21/2026, 4:02 PMctx.shutdown() (or otherwise tear down the session) on every participant disconnect if you expect brief reconnects.
• Instead, allow the session to persist through short network blips by disabling automatic close-on-disconnect and/or using a short reconnection grace period before shutting down.
Why
• If you shut down the context immediately, all I/O is closed and post‑shutdown cleanup begins; the session cannot be recovered if the participant reconnects.
• Letting the session stay alive for a short time avoids unnecessary reinitialization and preserves state (agent session, buffers, etc.) for quick reconnects.
Practical options you can use
• Disable auto-close on disconnect:
◦ Use the close_on_disconnect option (e.g., set close_on_disconnect=False in Room options). This prevents the AgentSession from automatically closing when the linked participant leaves.
• Implement a reconnection grace period:
a. On disconnect, start a short timer (for example, a few seconds — tune to your app's needs).
b. If the participant reconnects before the timer expires, cancel shutdown and continue the session.
c. If the timer expires without reconnection, call ctx.shutdown() and run your cleanup.
• If you prefer server-driven behavior, make the grace window configurable per room/session so different flows can use different timeouts.
What I can help with next
• Suggest a default grace period length based on your use case (low-latency calls vs longer interactive sessions).
• Show sample code for using close_on_disconnect and implementing a reconnection timer in your language (Node.js or Python).
• Review your current shutdown/reconnect logic and recommend adjustments.
Would you like a code example for implementing the reconnection grace period in Node.js or Python?

03/21/2026, 4:05 PMclose_on_disconnect=False) and then use the participant/connection state events LiveKit emits to decide when to shut down.
Recommended approach using LiveKit events
• Disable automatic closure:
◦ Set close_on_disconnect=False so the AgentSession does not automatically close when the participant leaves.
• Rely on connection/participant state events that LiveKit provides:
◦ Listen for the participant leaving/disconnected events to detect the initial disconnect.
◦ Listen for participant rejoined/connected events to detect reconnection.
• Use those events to decide shutdown:
◦ Do not call ctx.shutdown() on the first disconnect event.
◦ If you receive a reconnect event before you decide to close, continue the session.
◦ If you observe definitive end signals (for example, an explicit room close, session end, or a final "participant left and will not return" signal from your app logic), then call ctx.shutdown().
Why this is safer than immediate shutdown
• An immediate shutdown cannot be reversed if the participant quickly reconnects.
• Listening to LiveKit connection/participant events gives you authoritative signals about presence without forcing you to invent low-level reconnection detection.
If you’d like, I can:
• Provide concrete example code showing how to wire the participant/connection events to manage shutdown in Node.js or Python.
• Recommend a small, minimal fallback timer pattern (only a few seconds) that pairs with event listening for edge cases (optional).
Which language would you prefer the example in — Node.js or Python?
