| Level | Trigger | What change |
|-------|---------|-------------|
| Lite | /ponytail lite | Build what's asked, name the lazier alternative in one line. |
| Full | /ponytail | The ladder enforced: YAGNI → stdlib → native → one line → minimum. Default. |
| Ultra | /ponytail ultra | YAGNI extremist. Deletion before addition. Challenges requirements before building. |
Level sticks until changed or session end.
| Skill | Trigger | What it does |
|-------|---------|--------------|
| ponytail | /ponytail | Lazy mode itself. Simplest solution that works. |
| ponytail-review | /ponytail-review | Over-engineering review: L42: yagni: factory, one product. Inline. |
| ponytail-audit | /ponytail-audit | Whole-repo over-engineering audit: ranked list of what to delete. |
| ponytail-debt | /ponytail-debt | Harvest ponytail: shortcut comments into a tracked ledger. |
| ponytail-gain | /ponytail-gain | Measured-impact scoreboard: less code, less cost, more speed. |
| ponytail-help | /ponytail-help | This card. |
Codex uses @ponytail, @ponytail-review, and @ponytail-help; Claude Code
and OpenCode use the slash-command forms above (OpenCode ships all six as
slash commands).
Say "stop ponytail" or "normal mode". Resume anytime with /ponytail.
/ponytail off also works.
Default mode = full, auto-active every session. Change it:
Environment variable (highest priority):
export PONYTAIL_DEFAULT_MODE=ultra
Config file (~/.config/ponytail/config.json, Windows: %APPDATA%\ponytail\config.json):
{ "defaultMode": "lite" }
Set "off" to disable auto-activation on session start, activate manually
with /ponytail when wanted.
Resolution: env var > config file > full.
Enable auto-update once: open /plugin, go to Marketplaces, pick ponytail, Enable auto-update. Claude Code then pulls new versions at startup (run /reload-plugins when it prompts). Manual refresh: /plugin marketplace update ponytail then /reload-plugins.
If /plugin is not recognized, your Claude Code is out of date. Update it (npm install -g @anthropic-ai/claude-code@latest, or brew upgrade claude-code) and restart. Other hosts use their own update flow.

Take google/ponytail-help from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference npm.
Without those the skill loads but fails at the first command.
