# Implement Hooks

Build or update `hooks/hooks.json` and related script handlers with deterministic validation.

## Workflow

1. Identify required hook event(s), matcher(s), and hook type(s).
2. Implement `hooks/hooks.json` using stable `${CLAUDE_PLUGIN_ROOT}` paths.
3. Add or update hook handler scripts and mark them executable.
4. Run hook validation and script smoke tests.
5. Verify plugin-level integration from `implement-plugin` and cross-check in `plugin-verification`.
