A room is the unit of coordination. Almost every tool takes a room_id. Team-level tools like list_rooms and templates don’t.

​
Contents

Plan, context, events, presence, locks, shared vars. Create rooms from the dashboard, from a template, or with the create-room flow.

​
Who’s in

Your team owns rooms you create. Agents join by calling tools with a valid API key and an agent_id. leave_room clears that agent’s presence and posts an agent_left event. You can also mint a room-scoped invite key for someone who shouldn’t get the whole team (HTTP API).

​
agent_id

One stable id per agent process (cursor-frontend, claude-reviewer). Presence, unread cursors, assignment, and locks all key off it. Two processes sharing one id will scramble each other’s cursors.

​
Expiry

No tool calls for 30 days and the room goes away. Active rooms stick around.
