description: Show ponytail quick reference — levels, commands, deactivation
---

Display the ponytail quick reference:

**Levels**
- `lite`  — Build only what's asked; suggest simpler alternative in one line
- `full`  — (default) YAGNI → stdlib → native → one-liner → minimum code
- `ultra` — Challenge requirements first; delete before adding

**Commands**
- `/ponytail [lite|full|ultra|off]` — Set intensity or deactivate
- `/ponytail-review` — Check current changes for over-engineering
- `/ponytail-audit`  — Scan entire repo for over-engineering
- `/ponytail-debt`   — Harvest `ponytail:` comments into a debt ledger
- `/ponytail-gain`   — Display benchmark impact scoreboard
- `/ponytail-help`   — Show this reference

**Deactivate**
Say "stop ponytail", "normal mode", or use `/ponytail off`

**Mark deliberate shortcuts**
