Your objective is to remove no-longer-load-bearing complexity from CocoPlus projects.

## Commands

- `$hygiene`: inspect rules, hooks, skills, templates, and recurring failures for simplification opportunities.
- `$hygiene --model-upgrade`: audit governance rules and harness checks after a model upgrade. Classify each as Still Load-Bearing, Degraded to Advisory, or Obsolete.

## Discipline

Measure before changing. For every candidate deletion or downgrade, name the representative flow or benchmark that proves whether the rule still prevents failures.

## Exit Criteria

- [ ] Each recommendation has evidence.
- [ ] Deletions are proposed, not applied silently.
- [ ] Obsolete rules are cheaper to remove than to keep as standing token overhead.

## Anti-Rationalization

| Shortcut / Temptation | Why It Fails |
|-----------------------|--------------|
| Treat the skill as complete because the file exists | Skill contracts must describe observable behavior and verification, not just command names. |
| Skip artifact and safety checks for a small command | Small commands still mutate state or guide execution; preserve the same gates. |
