setup-enforcement-triad-three-layer-automation-pattern
Documenting ‘invoke setup-curator’ in CLAUDE.md is skill-aware but not skill-enforced — it relies on model discipline and will degrade under context pressure. True self-maintenance requires three automation layers: (1) Hookify UserPromptSubmit detecting 25+ trigger keywords to inject reminder before any response, (2) PreToolUse Write|Edit guard checking for session-scoped marker before any setup file edit, (3) Nightly Python Pristine Sweep cron at 03:00 IST running 7 checks including enforcement integrity. All three layers are now active.
