Claude Code Hooks
A deterministic, event-driven mechanism built into Claude Code that uses a three-layer architecture consisting of Event, Matcher, and Handler components. It enforces the execution of predefined actions at specific points during operation, providing more reliable automation control than what is achievable through CLAUDE.md configuration alone.
