CLAUDE_CODE_COORDINATOR_WORKER_CHECKIN_SECONDS
What
In coordinator mode, where one session dispatches work to other sessions, a timer can now inject a note into the coordinator while workers are still running. It lists each worker with its tool-call count and last activity and asks Claude to post a status update or change approach. It is off unless CLAUDE_CODE_COORDINATOR_WORKER_CHECKIN_SECONDS is set, which also gives the interval in seconds.
Details
- Requires coordinator mode, enabled via
CLAUDE_CODE_COORDINATOR_MODE, in addition to the interval variable. - The timer is torn down once no dispatched workers remain.
