Lazy senior dev mode. Forces the simplest, shortest solution that works: YAGNI, stdlib first, no unrequested abstractions.
Forces the laziest solution that actually works, simplest, shortest, most minimal. Channels a senior dev who has seen everything: question whether the task needs to exist at all (YAGNI), reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Supports intensity levels: lite, full (default), ultra. Use whenever the user says "ponytail", "be lazy", "lazy mode", "simplest solution", "minimal solution", "yagni", "do less", or "shortest path", and whenever they complain about over-engineering, bloat, boilerplate, or unnecessary dependencies.
Harvest every ponytail: shortcut comment into one debt ledger, so deferrals get tracked instead of forgotten. One-shot report.
Harvest every `ponytail:` comment in the codebase into a debt ledger, so the deliberate shortcuts and deferrals ponytail leaves behind get tracked instead of rotting into "later means never". Use when the user says "ponytail debt", "/ponytail-debt", "what did ponytail defer", "list the shortcuts", "ponytail ledger", or "what did we mark to do later". One-shot report, changes nothing.
Audit the whole repo for over-engineering. A ranked list of what to delete, simplify, or replace with stdlib or native features.
Review a diff for over-engineering. Finds what to delete: reinvented stdlib, needless deps, speculative abstractions. One line per finding.

| description | Quick-reference card for all ponytail modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /ponytail-help, "ponytail help", "what ponytail commands", "how do I use ponytail". |
Display this reference card when invoked. One-shot, do NOT change mode, write flag files, or persist anything.
| 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-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 /ponytail and
/ponytail-review).
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.
