Thanks — I’m responding to your question about closing a LiveKit voice connection when a Gemini Realtime tool call returns a parameter set to true. Short answer: have the tool return a structured result (e.g.,

{ should_end_call: true }

), check that result in your agent/handler immediately after the tool call, then shut down the agent session and (optionally) delete the LiveKit room to end the call for all participants. Example patterns you can follow: 1) Agent/tool returns the flag • Tool returns JSON like

{ "should_end_call": true, "reason": "safety" }

. 2) Act on the result (Python-style pseudocode)

result = await analyze_user_request(context, query)
if result.get("should_end_call"):
    # optional: send final reply to user
    await context.session.generate_reply(instructions="Ending the call now.")
    # end the LiveKit room for all participants
    await job_ctx.api.room.delete_room(api.DeleteRoomRequest(room=job_ctx.room.name))
    # gracefully shut down the agent session (drain finishes speech)
    await context.session.shutdown(drain=True)

3) Node.js equivalent • Use the agent context/tool result check, call

await ctx.session.generateReply(...)

if needed, call

RoomServiceClient.deleteRoom(...)

to remove the room, then

await ctx.shutdown()

to end the session. Key notes • Return a clear boolean flag from the tool so the agent can react deterministically. • Use

session.shutdown(drain=True)

(or

ctx.shutdown()

in Node) to let in-flight speech finish before closing. • Deleting the room ends the call for everyone; shutting down the session ends the agent’s connection only. If you want, tell me: • which SDK/language you’re using (Python or Node), and • whether you want to end the call for everyone or only disconnect the agent — I’ll provide a concrete code snippet for that environment.
