Use this skill when a Leader needs to identify the current Matrix room or prepare the Matrix task room before Quick Task or Project Work state exists.
Describe Room
Call roomflow describe_room when a Matrix room's purpose is unclear.
Classify from Matrix state:
- Source channel / requester room: external channel, or Matrix room whose name indicates DM or Team room.
- Task room: Matrix room whose name starts with
TASK：<projectId>, or whose topic/tags carry a Project/Task marker.
Do not infer room purpose from joined-room IDs alone.
Create Or Reuse Task Room
From a Source channel / requester room, call roomflow create_task_room before
creating project or task state.
Pass a stable projectId. The tool normalizes the Matrix room name to
TASK：<projectId> and reuses task rooms only by that project id.
Pass the current source metadata exactly as received, such as DingTalk
sourceRoomId and sender, so project state can keep the requester route.
Do not use source room or sender identity to decide task-room reuse. Different
projects from the same DingTalk group or same person still get different task
rooms.
Pass the complete Matrix user IDs for Workers who must receive or observe work in the task room. Use the returned Matrix room as the task room for the handoff, project state, task delegation, and Worker completion reports.
