What
When a hook that runs on your prompt hits its time limit, Claude Code logs a warning naming the hook event and records a timeout event with the event name, the limit and the actual duration. Previously a timed-out prompt hook left no trace. The limit is still 30000ms unless the hook sets its own timeout.
Details
- The evaluator stamps a start time and reports only when its own signal aborts while the session is still running, so ordinary session cancellation is not counted as a hook timeout.
