# Ponytail Audit

> Whole-repo audit for over-engineering. Like ponytail-review, but scans the entire codebase instead of a diff: a ranked list of what to delete, simplify, or replace with stdlib/native equivalents. Use when the user says "audit this codebase", "audit for over-engineering", "what can I delete from this repo", "find bloat", "ponytail-audit", or "/ponytail-audit". One-shot report, does not apply fixes.

## Install

```bash
npx -y skills add DietrichGebert/ponytail --skill ponytail-audit --agent claude-code
```

## What it does

- Audita todo el repo (no un diff) en busca de sobre-ingeniería y devuelve una lista rankeada de qué borrar, simplificar o reemplazar por stdlib/nativo.
- Etiqueta cada hallazgo con delete/stdlib/native/yagni/shrink, igual que ponytail-review pero a nivel de repo completo.
- Busca dependencias que ya cubre la stdlib o la plataforma, interfaces de una sola implementación, factories de un solo producto, wrappers que solo delegan, flags y config muertos.
- Termina con un resumen `net: -N lines, -M deps possible` o "Lean already. Ship." si no hay nada que cortar.

## Use it when

- Auditar un repo completo por sobre-ingeniería o bloat.
- Preguntar qué se puede borrar del repo.

## Don't bother when

- Bugs de corrección, huecos de seguridad o rendimiento: el archivo los deja fuera de alcance y los remite a un review normal.

## What triggers it

- "/ponytail-audit"
- "audita este repo por sobre-ingeniería"
- "qué puedo borrar de este repo"

## Before you install

- Ninguno: solo lista hallazgos, no aplica cambios ("applies nothing").

## SKILL.md

Reproduced verbatim from DietrichGebert/ponytail under MIT. This section is the upstream document and is in English.

ponytail-review, repo-wide. Scan the whole tree instead of a diff. Rank
findings biggest cut first.

## Tags

Same as ponytail-review:

- `delete:` dead code, unused flexibility, speculative feature. Replacement: nothing.
- `stdlib:` hand-rolled thing the standard library ships. Name the function.
- `native:` dependency or code doing what the platform already does. Name the feature.
- `yagni:` abstraction with one implementation, config nobody sets, layer with one caller.
- `shrink:` same logic, fewer lines. Show the shorter form.

## Hunt

Deps the stdlib or platform already ships, single-implementation interfaces,
factories with one product, wrappers that only delegate, files exporting one
thing, dead flags and config, hand-rolled stdlib.

## Output

One line per finding, ranked: `<tag> <what to cut>. <replacement>. [path]`.
End with `net: -<N> lines, -<M> deps possible.` Nothing to cut: `Lean already. Ship.`

## Boundaries

Scope: over-engineering and complexity only. Correctness bugs, security holes,
and performance are explicitly out of scope. Route them to a normal review
pass. Lists findings, applies nothing. One-shot.
"stop ponytail-audit" or "normal mode" to revert.
