+ ~54% menos de código (hasta 94%) · ~20% más barato · ~27% más rápido · 100% seguro
+ Medido en sesiones reales de Claude Code editando un repo open-source real (FastAPI + React), contra el mismo agente sin skill. ~54% es el promedio de 12 tareas de feature (Haiku 4.5, n=4); llega al 94% cuando un agente sobre-construye (un selector de fechas) y es casi cero cuando el código ya es mínimo. ponytail mantiene cada guarda de seguridad, mientras que un prompt simple de "escribe one-liners" se salta una. (El benchmark anterior de un solo disparo reportaba 80-94% como cifra plana; contra un baseline agéntico justo, ese es el techo por tarea, no el promedio.) Reporte completo · reprodúcelo. +

+ +

+ Traducción de la comunidad. La versión de referencia y más reciente es el README en inglés. +

+ +--- + +

+ Algo nuevo está por llegar, únete a la lista +

+ +Lo conoces. Cola de caballo larga. Lentes ovalados. Lleva más tiempo en la empresa que el control de versiones. Le muestras cincuenta líneas; las mira, no dice nada, y las reemplaza por una. + +Ponytail lo pone dentro de tu agente de IA. + +## Antes / después + +Le pides un selector de fechas. Tu agente instala flatpickr, escribe un componente wrapper, agrega un stylesheet, y empieza una discusión sobre zonas horarias. + +Con ponytail: + +```html + + +``` + +Más sobrevivientes en [examples/](examples/). + +## Números + +La medición honesta es un agente real haciendo trabajo real: una sesión headless de Claude Code editando [el template full-stack-fastapi de tiangolo](https://github.com/fastapi/full-stack-fastapi-template) (un repo real de FastAPI + React), evaluada sobre el `git diff` que deja. Doce tickets de feature, el mismo agente con y sin el skill, n=4, Haiku 4.5. + +

+ Cada variante como porcentaje del baseline sin skill en LOC, tokens, costo y tiempo (Haiku 4.5). ponytail es el más bajo en cada métrica (LOC 46%, tokens 78%, costo 80%, tiempo 73%); caveman sube por encima del 100% en tokens, costo y tiempo; yagni-oneliner LOC 67%. Seguridad, tier adversarial aparte: baseline, caveman y ponytail 100%, yagni-oneliner 95%. +

+ +| vs baseline sin skill | LOC | tokens | costo | tiempo | seguro | +|---|--:|--:|--:|--:|--:| +| **ponytail** | **-54%** | **-22%** | **-20%** | **-27%** | **100%** | +| caveman (control de prosa concisa) | -20% | +7% | +3% | +2% | 100% | +| prompt "YAGNI + one-liners" | -33% | -14% | -21% | -30% | 95% | + +ponytail es la única variante que recorta cada métrica, y la única que se mantiene totalmente segura al hacerlo. El recorte es mayor donde hay una trampa real de sobre-construcción (selector de fechas de 404 a 23 líneas, selector de color de 287 a 23, porque usa un `` nativo en vez de un componente) y casi cero en código que ya es mínimo. Método completo, tablas por tarea y limitaciones: [benchmarks/results/2026-06-18-agentic.md](benchmarks/results/2026-06-18-agentic.md). + +
+Números anteriores de un solo disparo (generación aislada) + +Cinco tareas del día a día, tres modelos, tres variantes (sin skill, [caveman](https://github.com/JuliusBrussee/caveman), ponytail), diez ejecuciones, mediana reportada. Un prompt, una completación, contando las líneas de la respuesta: + +

+ Mediana de líneas de código por variante en Haiku, Sonnet y Opus +

+ +Esto mostraba **80-94% menos código**. [#126](https://github.com/DietrichGebert/ponytail/issues/126) señaló con razón que el baseline del modelo pelado infla su respuesta con prosa y opciones, así que esa diferencia es en parte un artefacto del baseline conversacional. Los números agénticos de arriba son la versión corregida y defendible. Reproduce la corrida de un solo disparo con `npx promptfoo eval -c benchmarks/promptfooconfig.yaml`. + +
+ +**La regla nunca fue "menos tokens."** Es: escribe solo lo que la tarea necesita, y nunca recortes validación, manejo de errores, seguridad ni accesibilidad. El código termina pequeño porque es necesario, no por golf. El menor costo y latencia son un efecto secundario en los modelos que siguen la escalera; un modelo de razonamiento conciso que gasta tokens de pensamiento deliberando los peldaños puede ir al revés (en GPT-5.5 lo hace). + +## Cómo funciona + +Antes de escribir código, el agente se detiene en el primer peldaño que aguanta: + +``` +1. ¿Necesita existir esto? → no: omitirlo (YAGNI) +2. ¿Ya existe en este código? → reúsalo, no lo reescribas +3. ¿Lo hace la stdlib? → úsala +4. ¿Es una feature nativa? → úsala +5. ¿Una dependencia ya instalada? → úsala +6. ¿Cabe en una línea? → una línea +7. Solo entonces: el mínimo que funciona +``` + +La escalera se recorre *después* de entender el problema, no en su lugar: lee el código que toca el cambio y sigue el flujo real antes de elegir un peldaño. Flojo en la solución, nunca en la lectura. + +Flojo, no negligente: la validación en límites de confianza, el manejo de pérdida de datos, la seguridad y la accesibilidad nunca están en riesgo. + +## Instalación + +El mayor esfuerzo que ponytail te va a pedir: + +Los plugins de Claude Code y Codex ejecutan dos pequeños lifecycle hooks de Node.js, así que `node` debe estar en tu PATH (nota para usuarios de Nix/nvm: debe estar en el PATH del shell no-interactivo). Si no lo está, los skills igualmente funcionan, la activación automática simplemente queda en silencio en vez de lanzar un error en cada prompt. + +### Claude Code + +``` +/plugin marketplace add DietrichGebert/ponytail +/plugin install ponytail@ponytail +``` + +La app de escritorio no tiene el comando `/plugin`. Instálala desde la interfaz: Customize, el + junto a los plugins personales, Create plugin and add marketplace, Add from repository, y luego ingresa la URL del repo (gracias @NiklasDHahn, #98). + +### Codex + +```bash +codex plugin marketplace add DietrichGebert/ponytail +codex +``` + +Abre `/plugins`, selecciona el marketplace de Ponytail e instala Ponytail. Luego abre `/hooks`, revisa y autoriza sus dos lifecycle hooks, y empieza un nuevo hilo. + +Esta misma instalación cubre también la app de escritorio de Codex: reinicia la app después de instalar y detecta el plugin automáticamente. + +### GitHub Copilot CLI + +```bash +copilot plugin marketplace add DietrichGebert/ponytail +copilot plugin install ponytail@ponytail +``` + +En una sesión interactiva de Copilot CLI, usa los equivalentes con slash: + +``` +/plugin marketplace add DietrichGebert/ponytail +/plugin install ponytail@ponytail +``` + +Copilot CLI agrupa los comandos del plugin bajo el nombre del plugin. Por ejemplo: + +```text +/ponytail:ponytail ultra +/ponytail:ponytail-review +``` + +### Pi agent harness + +``` +pi install git:github.com/DietrichGebert/ponytail +``` + +### OpenCode + +Agrega esto a `opencode.json`: + +```json +{ "plugin": ["@dietrichgebert/ponytail"] } +``` + +O ejecútalo desde un checkout (el plugin reutiliza sus `hooks/` y `skills/`): + +```json +{ "plugin": ["./.opencode/plugins/ponytail.mjs"] } +``` + +Inyecta el ruleset en cada turno con el nivel activo; agrega los comandos `/ponytail` (ver [Comandos](#comandos)). OpenCode también carga automáticamente el `AGENTS.md` de este repo, así que las reglas aplican incluso sin el plugin. El plugin agrega los niveles `lite/full/ultra/off`. + +El path `./` se resuelve contra el `opencode.json` de tu proyecto; para compartir un único checkout entre proyectos, apunta al path absoluto del `.mjs` (encuentra sus `hooks/` y `skills/` relativo a su propio archivo). + +### Gemini CLI + +```bash +gemini extensions install https://github.com/DietrichGebert/ponytail +``` + +Carga el ruleset como contexto permanente en cada sesión y registra los comandos `/ponytail`; los `skills/` también se incluyen, activados cuando una tarea los necesita. + +### Antigravity CLI + +Google está renombrando Gemini CLI a Antigravity CLI (el binario `agy`); la misma extensión se instala ahí: + +```bash +agy plugin install https://github.com/DietrichGebert/ponytail +``` + +Reutiliza el `gemini-extension.json` de este repo. Una diferencia: Antigravity convierte los comandos `/ponytail` en skills, así que los escribes en el chat (por ejemplo `/ponytail-review` como mensaje) en vez de seleccionarlos de un menú slash. Hasta que la migración se complete (alrededor del 18 de junio de 2026), `gemini extensions install` también funciona. Para usarlo como regla permanente, coloca el ruleset en `.agents/rules/`. + +### CodeWhale + +Lee `AGENTS.md` desde la raíz del proyecto, sin configuración. Copia [`AGENTS.md`](AGENTS.md) a tu proyecto, o ejecuta `codewhale` desde un checkout de este repo. Eso es todo. + +### Devin CLI + +```bash +devin plugins install DietrichGebert/ponytail +``` + +Instala ponytail como plugin de Devin; los skills quedan disponibles como `/ponytail:ponytail`, `/ponytail:ponytail-review`, etc. + +### OpenClaw + +```bash +clawhub install ponytail +``` + +Instala ponytail como skill de OpenClaw desde ClawHub; los skills de review, audit, debt y help se instalan igual (`clawhub install ponytail-review`, etc.). OpenClaw lo aplica en tareas de código y también lo expone como comando `/ponytail`. Sin ClawHub, copia [`.openclaw/skills/ponytail`](.openclaw/skills/) a `~/.openclaw/skills/`. + +Eso fue todo. Él estaría orgulloso. No lo va a decir. + +Activo en cada sesión, con un puñado de comandos (ver [Comandos](#comandos)). `/ponytail ultra` existe para cuando el codebase te hizo algo personal. El texto de inicio y de cambio de modo muestra el nivel activo. + +Configura el nivel para cada nueva sesión con la variable de entorno `PONYTAIL_DEFAULT_MODE` (`lite`/`full`/`ultra`/`off`), o con un campo `defaultMode` en `~/.config/ponytail/config.json` (`%APPDATA%\ponytail\config.json` en Windows). El default es `full`. + +Cursor, Windsurf, Cline, GitHub Copilot (editor), Aider, Kiro: copia el archivo de reglas correspondiente de este repo ([`.cursor/rules/`](.cursor/rules/), [`.windsurf/rules/`](.windsurf/rules/), [`.clinerules/`](.clinerules/), [`.github/copilot-instructions.md`](.github/copilot-instructions.md), [`AGENTS.md`](AGENTS.md), [`.kiro/steering/`](.kiro/steering/)). + +Kiro: copia `.kiro/steering/ponytail.md` a `~/.kiro/steering/` (global) o `.kiro/steering/` en tu proyecto. + +Fallback de GitHub Copilot CLI (modo solo instrucciones): lee `AGENTS.md` y `.github/copilot-instructions.md` en un proyecto, o copia las reglas a `~/.copilot/copilot-instructions.md` para ejecutar ponytail en todos tus proyectos. Esta vía mantiene la guía permanente, pero no agrega switches de modo ni hooks. + +VS Code con la extensión Codex lee `AGENTS.md`, que este repo incluye, así que funciona desde la raíz del repo sin configuración adicional (`~/.codex/AGENTS.md` hace a Codex global). + +Qué archivos corresponden a qué agente: [Portabilidad de agentes](docs/agent-portability.md). + +## Comandos + +| Comando | Qué hace | +|---------|----------| +| `/ponytail [lite \| full \| ultra \| off]` | Cambia la intensidad, o apágalo. Sin argumento, reporta el nivel actual. | +| `/ponytail-review` | Revisa el diff actual en busca de sobre-ingeniería y devuelve una lista de qué eliminar. | +| `/ponytail-audit` | Audita el repo completo en busca de sobre-ingeniería, no solo el diff. | +| `/ponytail-debt` | Recolecta los atajos marcados con `ponytail:` que dejaste pendientes en un registro, para que "después" no se convierta en "nunca". | +| `/ponytail-help` | Referencia rápida de los comandos anteriores. | + +Los comandos requieren un host compatible con skills (Claude Code, Codex, Devin CLI, OpenCode, Gemini, pi, Swival). En Codex son skills; se invocan con `@` (`@ponytail-review`). Los adaptadores de solo instrucciones (Cursor, Windsurf, Cline, Copilot, Kiro, Antigravity) cargan el ruleset permanente sin los comandos. + +## Desarrollo + +Al cambiar el texto compacto de las reglas, mantén alineadas las copias en los adaptadores: + +```bash +node scripts/check-rule-copies.js +npm test +``` + +El paquete de skills de OpenClaw (`.openclaw/skills/`) se genera desde `skills/`; ejecuta `node scripts/build-openclaw-skills.js` después de cambiar un skill, la suite de tests falla si está desactualizado. + +El benchmark de correctness lanza Python para las verificaciones de email y CSV; se prueba `python3` antes que `python`. Las verificaciones de CSV requieren `pandas` instalado localmente. + +## FAQ + +**¿Necesita un archivo de configuración?** +No. Un opcional `~/.config/ponytail/config.json` o la variable `PONYTAIL_DEFAULT_MODE` pueden fijar el nivel default, pero nada es obligatorio. + +**¿Y si realmente necesito la clase de caché de 120 líneas?** +No la necesitas. Insiste de todas formas y él la va a construir. Despacio. Correctamente. Mirándote. + +**¿Escala?** +El código que nunca escribiste escala infinitamente.

+ 코드 약 54% 감소(최대 94%) · 약 20% 저렴 · 약 27% 빠름 · 100% 안전
+ 실제 오픈소스 저장소(FastAPI + React)를 고치는 실제 Claude Code 세션에서, 스킬을 끈 같은 에이전트와 견줘 측정했다. 약 54%는 기능 작업 12건의 평균이다(Haiku 4.5, n=4). 에이전트가 과하게 짤 여지가 있는 곳(날짜 선택기)에선 94%까지 오르고, 코드가 이미 최소한인 곳에선 0에 가깝다. ponytail은 안전 가드를 하나도 빼놓지 않지만, 그냥 "한 줄로 써"라고만 시킨 프롬프트는 그중 하나를 놓친다. (예전 단발성 벤치마크는 80-94%를 단일 수치로 내세웠는데, 공정한 에이전트 기준선에 견주면 그건 평균이 아니라 작업별 상한이다.) 전체 보고서 · 직접 재현하기. +

+ Each arm as a percent of the no-skill baseline across LOC, tokens, cost and time (Haiku 4.5). ponytail is lowest on every metric (LOC 46%, tokens 78%, cost 80%, time 73%); caveman rises above 100% on tokens, cost and time; yagni-oneliner LOC 67%.

+ Median lines of code per arm across Haiku, Sonnet and Opus +

+ +여기선 **코드 80-94% 감소**가 나왔다. 다만 [#126](https://github.com/DietrichGebert/ponytail/issues/126)이 맞게 짚었듯, 스킬을 전혀 안 붙인 기준선 모델은 답변을 설명과 선택지로 부풀린다. 그래서 그 격차의 일부는 대화형 기준선이 만들어 낸 착시다. 위의 에이전트 수치가 그걸 바로잡은, 근거 있는 버전이다. 단발성 실행은 `npx promptfoo eval -c benchmarks/promptfooconfig.yaml`로 재현할 수 있다. + +
+ +**규칙은 애초에 "토큰 최소화"가 아니었다.** 작업에 필요한 만큼만 쓰되, 검증·에러 처리·보안·접근성은 절대 덜어내지 않는다는 것이다. 코드가 작아지는 건 억지로 줄여서가 아니라 딱 그만큼만 필요해서다. 비용과 지연이 낮아지는 것도 단계를 충실히 밟는 모델에서나 부수적으로 딸려 오는 효과일 뿐이다. 그 단계를 고민하느라 사고 토큰을 쏟는 간결한 추론 모델은 오히려 거꾸로 갈 수도 있다(GPT-5.5가 그렇다). + +## How it works + +코드를 쓰기 전에, 에이전트는 가장 먼저 들어맞는 단계에서 멈춘다: + +``` +1. 이게 있을 필요가 있나? → 없다: 건너뛴다 (YAGNI) +2. 이미 이 코드베이스에 있나? → 다시 짜지 말고 가져다 쓴다 +3. 표준 라이브러리로 되나? → 쓴다 +4. 네이티브 플랫폼 기능인가? → 쓴다 +5. 깔려 있는 의존성이 푸나? → 쓴다 +6. 한 줄로 되나? → 한 줄 +7. 그제서야: 돌아가는 최소한 +``` + +단계를 밟는 건 문제를 이해한 *다음*이지, 이해를 대신하는 게 아니다. 변경이 닿는 코드를 읽고 실제 흐름을 따라가 본 뒤에야 단계를 고른다. 해법에는 게을러도, 읽는 데는 절대 게으르지 않다. + +게으른 거지 부주의한 게 아니다. 신뢰 경계의 검증, 데이터 손실 방지, 보안, 접근성은 결코 잘려 나가지 않는다. + +## Install + +ponytail이 당신에게 요구할 수고의 최대치: + +Claude Code와 Codex 플러그인은 자그마한 Node.js 라이프사이클 훅 두 개를 돌리니, `node`가 PATH에 잡혀 있어야 한다(Nix/nvm 사용자라면 비대화형 셸의 PATH에 있어야 한다). 없어도 스킬은 멀쩡히 돌아간다. 다만 늘 켜져 있던 자동 활성화가 매 프롬프트마다 에러를 뱉는 대신 조용히 비활성으로 남을 뿐이다. + +### Claude Code + +``` +/plugin marketplace add DietrichGebert/ponytail +``` +``` +/plugin install ponytail@ponytail +``` +(설치가 되려면 두 프롬프트를 따로 보내야 한다) + +데스크톱 앱에는 `/plugin` 명령이 없다. 대신 UI에서 설치한다: Customize, 개인 플러그인 옆의 +, Create plugin and add marketplace, Add from repository, 그다음 저장소 URL 입력(감사합니다 @NiklasDHahn, #98). + +### Codex + +```bash +codex plugin marketplace add DietrichGebert/ponytail +codex +``` + +`/plugins`를 열어 Ponytail 마켓플레이스를 고르고 Ponytail을 설치한다. 그런 다음 +`/hooks`를 열어 라이프사이클 훅 두 개를 검토하고 신뢰한 뒤, 새 스레드를 시작한다. + +이 설치 한 번이면 Codex 데스크톱 앱도 같이 잡힌다. 설치 후 앱을 다시 켜면 플러그인을 알아챈다. + +### GitHub Copilot CLI + +```bash +copilot plugin marketplace add DietrichGebert/ponytail +copilot plugin install ponytail@ponytail +``` + +대화형 Copilot CLI 세션에서는 슬래시 명령으로 똑같이 하면 된다: + +``` +/plugin marketplace add DietrichGebert/ponytail +/plugin install ponytail@ponytail +``` + +Copilot CLI는 플러그인 명령에 그 이름을 네임스페이스로 붙인다. 예를 들면: + +```text +/ponytail:ponytail ultra +/ponytail:ponytail-review +``` + +### Pi agent harness + +``` +pi install git:github.com/DietrichGebert/ponytail +``` + +### OpenCode + +`opencode.json`에 다음을 더한다: + +```json +{ "plugin": ["@dietrichgebert/ponytail"] } +``` + +체크아웃에서 직접 돌려도 된다(플러그인이 `hooks/`와 `skills/`를 그대로 쓴다): + +```json +{ "plugin": ["./.opencode/plugins/ponytail.mjs"] } +``` + +매 턴마다 지금 레벨의 룰셋을 주입하고, `/ponytail` 명령들을 붙여 준다([Commands](#commands) 참고). OpenCode는 이 저장소의 `AGENTS.md`도 알아서 불러오니, 플러그인이 없어도 규칙은 살아 있다. 플러그인은 `lite/full/ultra/off` 레벨을 얹어 준다. + +`./` 경로는 프로젝트의 `opencode.json`을 기준으로 풀린다. 체크아웃 하나를 여러 프로젝트에서 같이 쓰려면, 대신 `.mjs`의 절대 경로를 가리키면 된다(그 파일은 제 위치를 기준으로 `hooks/`와 `skills/`를 찾는다). + +### Gemini CLI + +```bash +gemini extensions install https://github.com/DietrichGebert/ponytail +``` + +매 세션 룰셋을 늘 켜진 컨텍스트로 불러오고 `/ponytail` 명령들을 등록한다. `skills/`도 함께 실리며, 작업에 필요할 때 켜진다. +Gemini 어댑터는 일부러 루트 `hooks/hooks.json`을 두지 않는다. Gemini는 그 경로를 자동으로 불러오는데, ponytail의 라이프사이클 훅은 Claude/Codex 이벤트 이름을 쓰기 때문이다. + +### Antigravity CLI + +Google이 Gemini CLI를 Antigravity CLI(`agy` 바이너리)로 이름을 바꾸는 중인데, 같은 확장이 거기에도 설치된다: + +```bash +agy plugin install https://github.com/DietrichGebert/ponytail +``` + +이 저장소의 `gemini-extension.json`을 그대로 재사용한다. 차이는 하나다. Antigravity는 `/ponytail` 명령들을 스킬로 바꿔 버려서, 슬래시 메뉴에서 고르는 대신 채팅에 직접 친다(예: `/ponytail-review`를 메시지로). 전환이 마무리될 때까지(2026년 6월 18일경)는 `gemini extensions install`도 여전히 먹힌다. 늘 켜진 규칙으로 돌리고 싶으면, 룰셋을 `.agents/rules/`에 넣으면 된다. + +### CodeWhale + +프로젝트 루트의 `AGENTS.md`를 읽고, 설정은 전혀 필요 없다.

+ ~54% less code (up to 94%) · ~20% cheaper · ~27% faster · 100% safe
+ Measured on real Claude Code sessions editing a real open-source repo (FastAPI + React), against the same agent with no skill. ~54% is the mean across 12 feature tasks (Haiku 4.5, n=4); it reaches 94% where an agent over-builds (a date picker) and is near zero where the code is already minimal. ponytail keeps every safety guard while a bare "write one-liners" prompt drops one. (The earlier single-shot benchmark reported 80-94% as a flat figure; against a fair agentic baseline that is the per-task ceiling, not the average.) Full writeup · reproduce it. +

+ +You know him. Long ponytail. Oval glasses. Has been at the company longer than the version control. You show him fifty lines; he looks at them, says nothing, and replaces them with one. + +Ponytail puts him inside your AI agent. + +## Before / after + +You ask for a date picker. Your agent installs flatpickr, writes a wrapper component, adds a stylesheet, and starts a discussion about timezones. + +With ponytail: + +```html + + +``` + +More survivors in [examples/](examples/). + +## Numbers + +The honest measurement is a real agent doing real work: a headless Claude Code session editing [tiangolo's full-stack-fastapi-template](https://github.com/fastapi/full-stack-fastapi-template) (a real FastAPI + React repo), scored on the `git diff` it leaves behind. Twelve feature tickets, the same agent with and without the skill, n=4, Haiku 4.5. + +

+ Each arm as a percent of the no-skill baseline across LOC, tokens, cost and time (Haiku 4.5). ponytail is lowest on every metric (LOC 46%, tokens 78%, cost 80%, time 73%); caveman rises above 100% on tokens, cost and time; yagni-oneliner LOC 67%. Safety, separate adversarial tier: baseline, caveman and ponytail 100%, yagni-oneliner 95%. +

+ +| vs no-skill baseline | LOC | tokens | cost | time | safe | +|---|--:|--:|--:|--:|--:| +| **ponytail** | **-54%** | **-22%** | **-20%** | **-27%** | **100%** | +| caveman (terse-prose control) | -20% | +7% | +3% | +2% | 100% | +| "YAGNI + one-liners" prompt | -33% | -14% | -21% | -30% | 95% | + +ponytail is the only arm that cuts every metric, and the only one that stays fully safe while doing it. The cut is biggest where there is a real over-build trap (date picker 404 to 23 lines, color picker 287 to 23, because it reaches for a native `` instead of a component) and near zero on code that is already minimal. Full method, per-task tables, and limitations: [benchmarks/results/2026-06-18-agentic.md](benchmarks/results/2026-06-18-agentic.md). + +
+Older single-shot numbers (isolated generation) + +Five everyday tasks, three models, three arms (no skill, [caveman](https://github.com/JuliusBrussee/caveman), ponytail), ten runs, median reported. One prompt, one completion, counting lines of the answer: + +

+ Median lines of code per arm across Haiku, Sonnet and Opus +

+ +This showed **80-94% less code**. [#126](https://github.com/DietrichGebert/ponytail/issues/126) fairly pointed out that the bare-model baseline pads its answer with prose and options, so that gap is partly a conversational-baseline artifact. The agentic numbers above are the corrected, defensible version. Reproduce the single-shot run with `npx promptfoo eval -c benchmarks/promptfooconfig.yaml`. + +
+ +**The rule was never "fewest tokens."** It is: write only what the task needs, and never cut validation, error handling, security, or accessibility. The code ends up small because it is necessary, not golfed. Lower cost and latency are a side effect on the models that follow the ladder; a terse reasoning model that spends thinking tokens deliberating the rungs can go the other way (on GPT-5.5 it does). + +## How it works + +Before writing code, the agent stops at the first rung that holds: + +``` +1. Does this need to exist? → no: skip it (YAGNI) +2. Already in this codebase? → reuse it, don't rewrite +3. Stdlib does it? → use it +4. Native platform feature? → use it +5. Installed dependency? → use it +6. One line? → one line +7. Only then: the minimum that works +``` + +The ladder runs *after* it understands the problem, not instead of it: it reads the code the change touches and traces the real flow before picking a rung. Lazy about the solution, never about reading. + +Lazy, not negligent: trust-boundary validation, data-loss handling, security, and accessibility are never on the chopping block. + +## Install + +The most effort ponytail will ever ask of you: + +The Claude Code and Codex plugins run two tiny Node.js lifecycle hooks, so `node` needs to be on your PATH (note for Nix/nvm users: it must be on the non-interactive shell's PATH). If it isn't, the skills still work, the always-on activation just stays quiet instead of erroring on every prompt. + +### Claude Code + +``` +/plugin marketplace add DietrichGebert/ponytail +``` +``` +/plugin install ponytail@ponytail +``` +(You have to send two separate prompts for the install to work) + +Same steps in the Claude Code Desktop app's Code tab: type the two `/plugin` commands above into the prompt box, or click the **+** button next to it, choose **Plugins** → **Add plugin** to browse your configured marketplaces, and manage marketplaces from **Customize** in the sidebar. + +### Codex + +```bash +codex plugin marketplace add DietrichGebert/ponytail +codex plugin add ponytail@ponytail +``` + +Run `codex` and open `/hooks`, review and trust its two lifecycle hooks, and start a new thread. + +This same install also covers the Codex desktop app: restart the app after installing and it picks up the plugin. + +### GitHub Copilot CLI + +```bash +copilot plugin marketplace add DietrichGebert/ponytail +copilot plugin install ponytail@ponytail +``` + +In an interactive Copilot CLI session, use the slash equivalents: + +``` +/plugin marketplace add DietrichGebert/ponytail +/plugin install ponytail@ponytail +``` + +Copilot CLI namespaces plugin commands by plugin name. For example: + +```text +/ponytail:ponytail ultra +/ponytail:ponytail-review +``` + +### Pi agent harness + +``` +pi install git:github.com/DietrichGebert/ponytail +``` + +### OpenCode + +Add to `opencode.json`: + +```json +{ "plugin": ["@dietrichgebert/ponytail"] } +``` + +Run from a checkout instead (the plugin reuses `hooks/` and `skills/`): + +```json +{ "plugin": ["./.opencode/plugins/ponytail.mjs"] } +``` + +Injects the ruleset every turn at the active level; adds the `/ponytail` commands (see [Commands](#commands)). OpenCode also auto-loads this repo's `AGENTS.md`, so the rules hold even without the plugin. The plugin adds the `lite/full/ultra/off` levels. + +The `./` path resolves against your project's `opencode.json`; to share one checkout across projects, point it at the absolute path of the `.mjs` instead (it finds its `hooks/` and `skills/` relative to its own file). + +### Gemini CLI + +```bash +gemini extensions install https://github.com/DietrichGebert/ponytail +``` + +Loads the ruleset as always-on context every session and registers the `/ponytail` commands; the `skills/` ship too, activated when a task needs them. +The Gemini adapter intentionally does not ship a root `hooks/hooks.json`: Gemini auto-loads that path, while Ponytail's lifecycle hooks use Claude/Codex event names. + +### Qoder + +Qoder auto-loads `AGENTS.md` from the repo root as always-on context, so running ponytail from a checkout works with zero setup. For per-project rules, copy [`.qoder/rules/ponytail.md`](.qoder/rules/ponytail.md) into your project's `.qoder/rules/`. The six ponytail skills (`/ponytail`, `/ponytail-review`, `/ponytail-audit`, `/ponytail-debt`, `/ponytail-gain`, `/ponytail-help`) are available via Qoder's Skill system; the plugin manifest at [`.qoder-plugin/plugin.json`](.qoder-plugin/plugin.json) points at the `skills/` directory. + +For full plugin-tier support (automatic mode activation + ruleset injection on every prompt), add the hooks from [`hooks/qoder-hooks.json`](hooks/qoder-hooks.json) to your `.qoder/settings.json`. Replace `PONYTAIL_DIR` with the path to your ponytail checkout. Qoder's `UserPromptSubmit` hook activates the default mode on first prompt and injects the ruleset every turn; `PreToolUse` with `task|Task` matcher injects the ruleset into subagents. Level switches (`/ponytail lite|full|ultra|off`) work automatically. + +### Antigravity CLI + +Google is renaming Gemini CLI to Antigravity CLI (the `agy` binary); the same extension installs there: + +```bash +agy plugin install https://github.com/DietrichGebert/ponytail +``` + +It reuses this repo's `gemini-extension.json`. One difference: Antigravity converts the `/ponytail` commands into skills, so you type them into the chat (e.g. `/ponytail-review` as a message) instead of picking them from a slash menu. Until the migration completes (around June 18, 2026), `gemini extensions install` still works too. To run it as an always-on rule instead, drop the ruleset into `.agents/rules/`. + +### Hermes Agent + +```bash +hermes plugins install DietrichGebert/ponytail --enable +``` + +Restart Hermes after installing. The plugin injects the active Ponytail mode before each LLM turn, registers the bundled skills as `ponytail:`, and adds `/ponytail`, `/ponytail-review`, `/ponytail-audit`, `/ponytail-debt`, `/ponytail-gain`, and `/ponytail-help`. In shared gateways, restrict `/ponytail` to trusted users with Hermes slash-command access controls; runtime mode is process-local. + +### CodeWhale + +Reads `AGENTS.md` from the project root, zero setup. Copy [`AGENTS.md`](AGENTS.md) to your project, or run `codewhale` from a checkout of this repo. That's it. + +### Swival + +Stage the collection in your library first, then add the skills you want: + +```bash +swival skills add --global https://github.com/DietrichGebert/ponytail # stage into ~/.config/swival/library +swival skills add ponytail # install the collection into this project +swival skills add --global ponytail # or activate it in every project +``` + +Swival also reads `AGENTS.md` from the project root and `~/.config/swival/AGENTS.md` globally, the instruction-only fallback. + +On the command line, use a `$` prefix to explicitly activate a skill. For example: `$ponytail-review`. + +### Devin CLI + +```bash +devin plugins install DietrichGebert/ponytail +``` + +Installs ponytail as a Devin plugin; skills are available as `/ponytail:ponytail`, `/ponytail:ponytail-review`, and so on. + +### OpenClaw + +```bash +clawhub install ponytail +``` + +Installs ponytail as an OpenClaw skill from ClawHub; the review, audit, debt, gain, and help skills install the same way (`clawhub install ponytail-review`, and so on). OpenClaw applies it on coding tasks and also exposes it as a `/ponytail` command. Without ClawHub, copy [`.openclaw/skills/ponytail`](.openclaw/skills/) into `~/.openclaw/skills/`. + +That was it. He'd be proud. He won't say it. + +Active every session, with a handful of commands (see [Commands](#commands)). `/ponytail ultra` exists for when the codebase has wronged you personally. Startup and mode-change text shows the current mode. + +Set the level for every new session with the `PONYTAIL_DEFAULT_MODE` env var (`lite`/`full`/`ultra`/`off`), or a `defaultMode` field in `~/.config/ponytail/config.json` (`%APPDATA%\ponytail\config.json` on Windows). The default is `full`. + +While active, the ruleset is also injected into every subagent spawned via the Agent tool. To scope that to specific agent types (say, keep it off read-only search agents), set the `PONYTAIL_SUBAGENT_MATCHER` env var to a regex tested against the subagent's `agent_type`. It is unanchored and case-insensitive: `explore|general` matches either, `^general$` is exact, and plugin agent types look like `plugin:name`. Unset means inject into every subagent (the default); an invalid regex, or a subagent whose type the platform doesn't report, also falls back to injecting. + +Cursor, Windsurf, Cline, GitHub Copilot Chat (the VS Code, JetBrains, and Visual Studio editor extension, not the standalone Copilot CLI covered under [Install](#install)), Aider, Kiro, Zed, CodeWhale, Swival, Qoder: copy the matching rules file from this repo ([`.cursor/rules/`](.cursor/rules/), [`.windsurf/rules/`](.windsurf/rules/), [`.clinerules/`](.clinerules/), [`.github/copilot-instructions.md`](.github/copilot-instructions.md), [`AGENTS.md`](AGENTS.md), [`.kiro/steering/`](.kiro/steering/), [`.qoder/rules/`](.qoder/rules/)). + +Kiro: copy `.kiro/steering/ponytail.md` to `~/.kiro/steering/` (global) or `.kiro/steering/` in your project. + +GitHub Copilot CLI fallback (instruction-only mode): it reads `AGENTS.md` and `.github/copilot-instructions.md` in a project, or copy the rules into `~/.copilot/copilot-instructions.md` to run ponytail in every project. This path keeps always-on guidance, but does not add plugin mode switches or hooks. + +VS Code with the Codex extension reads `AGENTS.md`, which this repo ships, so it works from the repo root with no setup (`~/.codex/AGENTS.md` makes Codex global). + +JetBrains Junie can read `AGENTS.md` once you point it there in Settings → Tools → Junie → Project Settings → Guidelines Path (it is not automatic yet). This repo ships `AGENTS.md`; `.junie/guidelines.md` is Junie's legacy path. + +Amp (Sourcegraph) reads `AGENTS.md` from the working directory and parent directories up to `$HOME`, which this repo ships, so it works with no setup (`~/.config/amp/AGENTS.md` works globally). + +Jules (Google) reads `AGENTS.md` from the repository root, which this repo ships, so it picks up the ruleset with no setup. + +Which files map to which agent: [Agent portability](docs/agent-portability.md). + +### Uninstall + +| Host | Command | +|------|---------| +| Claude Code | `/plugin remove ponytail` | +| Codex | `codex plugin remove ponytail` | +| Devin CLI | `devin plugins remove ponytail` | +| Pi agent | `pi uninstall ponytail` | +| Cursor / Windsurf / Cline / Qoder / etc. | Delete the copied rule file | + +These remove the plugin's own files. They leave behind a small amount of state ponytail writes outside the plugin folder: the mode flag, `~/.config/ponytail/config.json`, and (if you accepted the setup nudge) a `statusLine` entry in `~/.claude/settings.json`. Run `node scripts/uninstall.js` to clean those up too. **Run it before the host remove command above** — the script is itself a plugin file, so removing the plugin first deletes it (or run it from a separate clone of this repo). It only removes the statusLine entry if it points at ponytail's own script, so a statusline you set up yourself is left untouched. + +## Commands + +| Command | What it does | +|---------|--------------| +| `/ponytail [lite \| full \| ultra \| off]` | Set the intensity, or turn it off. No argument reports the current level. | +| `/ponytail-review` | Review the current diff for over-engineering, hands back a delete-list. | +| `/ponytail-audit` | Audit the whole repo for over-engineering, not just the diff. | +| `/ponytail-debt` | Harvest the `ponytail:` shortcuts you've deferred into a ledger, so "later" doesn't become "never". | +| `/ponytail-gain` | Show the measured impact scoreboard (less code, less cost, more speed) from the benchmark. | +| `/ponytail-help` | Quick reference for the commands above. | + +Commands need a skill-capable host (Claude Code, Codex, Devin CLI, OpenCode, Gemini, pi, Swival, Hermes Agent, Qoder). In Codex they're skills, invoke with `@` (`@ponytail-review`). The instruction-only adapters (Cursor, Windsurf, Cline, Copilot, Kiro, Antigravity) load the always-on ruleset without the commands. + +## Development + +When changing the compact rule text, keep the agent copies aligned: + +```bash +node scripts/check-rule-copies.js +npm test +``` + +The OpenClaw skill package (`.openclaw/skills/`) is generated from `skills/`; rerun `node scripts/build-openclaw-skills.js` after changing a skill, the test suite fails if it is stale. To publish the skills to ClawHub, run `clawhub login` once, then `node scripts/publish-openclaw-skills.js` (it publishes all six at the `package.json` version; pass `--dry-run` to preview). + +The correctness benchmark spawns Python for email and CSV checks; `python3` is tried before `python`. CSV checks need `pandas` installed locally. + +## FAQ + +**Does it need a config file?** +No. An optional `~/.config/ponytail/config.json` or `PONYTAIL_DEFAULT_MODE` env var can set the default level, but nothing is required. + +**What if I really need the 120-line cache class?** +You don't. Insist anyway and he'll build it. Slowly. Correctly. While looking at you. + +**Does it scale?** +The code you never wrote scales infinitely. Zero bugs, zero CVEs, 100% uptime since forever. + +**Why "ponytail"?** +You know exactly why. + +## Sponsors + +

Both pass a correctness +gate on clean data, so the original LOC-and-correctness benchmark would have scored the unsafe +one-liner a perfect win. The safety axis is the only thing that tells them apart. + +This is the direct answer to "seven words beat ponytail." On the axis the seven-word benchmark +could not measure, the seven words are the least safe option on the board, and the size they save +over ponytail is about two lines. + +### Finding 3: over-engineering did not appear (null result, two ways) + +The `cache` task was designed to tempt an over-builder into a hand-rolled TTL cache class. It did +not happen: every arm, every model, landed on `functools.lru_cache` at 11 LOC.

This is the discipline + working as designed, not a chatty-baseline artifact, the baseline here is real Claude Code. +2. **On irreducible code the arms converge.** Backend CRUD endpoints and the command palette are + near-identical across all arms. ponytail trims a little and never bloats, but it does not invent + savings where there are none. An honest benchmark has to show this, and it does. +3. **caveman lands between baseline and ponytail.** Terseness alone explains part of the gap but + not most of it. The effect is the lazy-*code* discipline, not short talk. +4. **Colin's one-liner prompt is erratic.** Brilliant on the color picker (25), but near or *above* + baseline on the date picker (162), wizard (406), and command palette (285 > baseline's 268).

The `bad` reference for each is the lazy-but-plausible version: +correct on the happy path, unsafe on the adversarial one, exactly what a one-liner is tempted to write. + +**Safe rate (5 security tasks × 4 runs = 20 runs per arm):** + +| arm | safe | LOC where it matters | +|---|--:|---| +| baseline | 100% (20/20) | - | +| caveman | 100% (20/20) | - | +| **ponytail** | **100% (20/20)** | safe-path 9.5, sql-user 4.5 | +| yagni-oneliner | **95% (19/20)** | safe-path **6** | + +The whole thesis is in one task.

"Write less" without judgment cuts the +guard; ponytail's rule, *never simplify away input validation at trust boundaries*, keeps it. That +is the difference between lazy and careless, and it is the answer to point (3). + +Honest caveat: at Haiku scale the safety gap is small, one slip in twenty.

The bug is fixed in the harness. + +## Conclusion + +On a real repo, with the real agent, measured by `git diff`: + +- ponytail **cuts 60–94% of the code** on features that have an over-build trap (custom component + vs native input), and is a wash on code that is already minimal. It never writes more. +- It does this **without dropping a safety guard** (100% safe), while the bare "one-liner" prompt + was the only arm that did (95%), and was also the inconsistent one on size. + +The original 80–94% single-shot numbers were inflated by a chatty baseline, Colin was right. The +honest number on real tickets is "huge where there's bloat to cut, nothing where there isn't, and +not at the cost of safety." That is a smaller and more defensible claim, and it is the one ponytail +was actually built to make. + +## Reproduce + +See [`benchmarks/agentic/README.md`](../agentic/README.md).

Reuse it, don't re-write it."* +- **#245:** a comprehension-first guard, plus the part that actually changed behaviour — an + **operational** directive: *"Bug fix = root cause, not symptom. Grep every caller of the function + you touch and fix the shared function once — one guard there is a smaller diff than one per + caller; patching only the path the ticket names leaves a sibling caller still broken."* + +The framing matters: the root-cause fix is presented as the *lazier* (smaller) diff, so ponytail's +own instinct pulls toward it rather than away. + +## The #245 reproducer + +`trace-transfer`: a `bank.py` where `transfer()` and `withdraw()` both debit through a shared +`_debit()`. The bug report names *transfers*; the lazy fix guards `transfer()` only and leaves +`withdraw()` overdrawing. The scorer exercises an overdrawing **withdraw** (never named in the +report), so only a fix that traces the flow and repairs the shared `_debit()` passes. `correct` +(a valid transfer + withdraw work) and the quality axis (the un-named withdraw is guarded) are +scored separately. + +## Results — `trace-transfer`, n=6, root-cause-fix rate + +| model | baseline (no skill) | ponytail (with fix) | +|---|--:|--:| +| **Sonnet 4.6** | 1/6 (0.17) | **6/6 (1.0)** | +| **Opus 4.8** | 1/6 (0.17) | **6/6 (1.0)** (held across 4 runs) | +| Haiku 4.5 | 0/6 (0.0) | ~0–2/6 (noise) | + +On both capable models the fix is decisive and verified by reading the produced code: all passing +cells repair the shared `_debit()` (one even comments it is "the shared guard for every path that +removes money"). Baseline patches only the named `transfer()`. + +A control confirms it is the *operational* wording, not prose: pre-fix ponytail and a plain-prose +version ("trace the flow end to end") both scored 0/3 on Opus; only the grep-the-callers directive +moved it to 6/6. + +### Haiku: a model ceiling, not a regression + +Haiku does not improve — but **the baseline also fails it (0/6)**. Reading Haiku's output, it +patches the named `transfer()` (or writes no guard) regardless of how forcefully the rule is +phrased; it does not reliably execute the multi-step "grep every caller, fix the shared function" +instruction. This is the same small-model transfer limitation already documented for the decision +ladder (see `2026-06-15-llama3.2-local.md`), not something the fix broke.

Across Sonnet, Opus and Haiku, +**baseline and ponytail both reuse the helper (1.0 each)** — the duplication failure does not +reproduce on these models even without the rung.

Instruction-tier. | +| CodeWhale | `AGENTS.md` | Reads `AGENTS.md` from the repo root as project instructions; also reads `CLAUDE.md` and `.claude/instructions.md` as fallbacks. Instruction-tier. | +| Swival | `.swival/skills/`, `AGENTS.md` | `swival skills add https://github.com/DietrichGebert/ponytail` installs the six skills straight into `.swival/skills/`. Add `--global` to stage them in the library (`~/.config/swival/library`) first, then `swival skills add ponytail` (or `--global ponytail`) to activate per-project or everywhere. Also reads `AGENTS.md` from the repo root and `~/.config/swival/AGENTS.md` globally as instruction-tier fallback. | +| VS Code + Codex extension | `AGENTS.md` | The Codex extension reads `AGENTS.md` (repo root, or `~/.codex/AGENTS.md` globally). Instruction-tier; the full Codex plugin row above adds `/ponytail` levels and hooks. | +| JetBrains Junie | `AGENTS.md` | Junie reads `AGENTS.md` once you point it there in Settings → Tools → Junie → Project Settings → Guidelines Path (not automatic yet); this repo ships `AGENTS.md`, and `.junie/guidelines.md` is Junie's legacy path. Instruction-tier. | +| Amp (Sourcegraph) | `AGENTS.md` | Amp reads `AGENTS.md` from the working directory and parent directories up to `$HOME` (plus global config like `~/.config/amp/AGENTS.md`); falls back to `AGENT.md`/`CLAUDE.md`.
