Competitive parity: Claude Code v2.1.83, Goose v1.27.x — both expose environment-change hook events.

Gap

No CwdChanged or FileChanged events in Zeph's hook/event system. Claude Code exposes these as lifecycle hooks; Goose has similar reactive triggers. Enables patterns like auto-reloading code index context when a file the agent referenced is modified externally.

Zeph applicability

• zeph-index has file watching (watch = true config) but does not emit hook events on change
• Hooks system (if present) could dispatch file_changed events to skills or tools
• Implementation sketch: watch via notify crate, emit HookEvent::FileChanged { path } and HookEvent::CwdChanged { new_cwd }; route through existing hook dispatcher
