# Ponytail Gain

> Show ponytail's measured impact as a compact scoreboard: less code, less cost, more speed, from the benchmark medians. One-shot display, not a persistent mode, and not a per-repo number. Trigger: /ponytail-gain, "ponytail gain", "what does ponytail save", "show ponytail impact", "ponytail scoreboard".

## Install

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

## What it does

- Muestra un scoreboard ASCII de una sola vez con el impacto medido de ponytail: líneas de código, costo y velocidad.
- Las cifras son medianas de benchmark publicadas (5 tareas cotidianas, 3 modelos: Haiku, Sonnet, Opus), no calculadas sobre el repo actual.
- Nunca imprime un número de ahorro por-repo, porque no existe una versión "sin skill" real de ese repo para restar.
- Apunta a /ponytail-debt y /ponytail-audit como las únicas cifras reales por-repo disponibles.

## Use it when

- Mostrar el impacto medido de ponytail (scoreboard).
- El usuario pregunta qué ahorra ponytail o pide ver el impacto.

## Don't bother when

- Reportar un ahorro real de este repo específico: el archivo lo prohíbe explícitamente.

## What triggers it

- "/ponytail-gain"
- "qué ahorra ponytail"
- "muéstrame el scoreboard de ponytail"

## Before you install

- Ninguno: despliegue de una sola vez, no cambia modo ni persiste nada.

# Ponytail Gain

Display this scoreboard when invoked. One-shot: do NOT change mode, write flag
files, or persist anything.

The figures are the published benchmark medians (5 everyday tasks: email
validator, debounce, CSV sum, countdown timer, rate limiter; three models:
Haiku, Sonnet, Opus). They are measured, not computed from the current repo.
Source: `benchmarks/` and the README.

## Scoreboard

Render plain ASCII bars. The bar length shows the measured range; the label
carries the exact figure:

```
  ponytail gain                     benchmark median · 5 tasks · 3 models

  Lines of code   no-skill  ████████████████████  100%
                  ponytail  ██▌·················    6–20%   ▼ 80–94%
  Cost            no-skill  ████████████████████  100%
                  ponytail  █████▌··············   23–53%  ▼ 47–77%
  Speed           ponytail  ▸ 3–6× faster

  This repo:  /ponytail-debt  (shortcuts you deferred)
              /ponytail-audit (what's still cuttable)
```

## Honesty boundary

These are benchmark medians, not this repo. NEVER print a per-repo savings
number ("you saved X lines/tokens here"): the unbuilt version was never
written, so there is no real baseline to subtract from in a live repo. The
only real per-repo figures come from `/ponytail-debt` (a counted ledger), and
this card points there instead of inventing one.

## Boundaries

One-shot display. Edits nothing, changes no mode.
"stop ponytail" or "normal mode": revert.
