Bug Description
The SendMessage tool's shutdown_response schema documents an optional reason field but omits that it is rejection-only — a reason accompanying approve: true is silently meaningless. Onesentence in the field description ("reason: rejection only; ignored on approve") would close the gap. Observed on Claude Code 2.1.221.
