project-template: Skill for Claude Code

.claude/skills/diagnostico/SKILL.md

diagnostico is a skill for Claude Code from polmarza/project-template. It costs 87 tokens per session (988 once invoked), scanned A, original, MIT.

A read-only project and environment check that reports missing documents, unfinished feature records, configuration problems, available integrations, and test status, with a proposed fix for each issue.

In plain words
What is it for?
Use it when first entering a project, before substantial work, or when something fails unexpectedly; it checks items such as Node, pnpm, environment variables, MCP servers, and tests.
Why use it?
It reveals project or setup problems before they disrupt a longer coding session, without changing anything automatically.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions Claude Code; mentions AGENTS.md.

This is polmarza/project-template's own configuration. It tells Claude Code how to work on project-template itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything project-template configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/verificar-cobertura.mjs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

diagnostico scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 14d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Revisa el estado del proyecto y del entorno, y da un parte de qué está bien, qué falta y cómo arreglarlo. Solo diagnostica: no arregla nada por su cuenta. Al terminar, propón las correcciones y deja que el usuario decida cuáles aplicar.

Ejecútalo cuando alguien entra al proyecto por primera vez, cuando algo falla sin motivo aparente o antes de una sesión larga, para no descubrir a mitad que faltaba media configuración.

No es el /doctor de Claude Code. Ese revisa la instalación de Claude Code, el coste en contexto de skills y MCPs, y la calidad de las instrucciones (/doctor prompt-audit); este revisa el proyecto. Se complementan: si el problema parece del agente y no del repo, sugiere /doctor.

Qué comprobar

1. Documentación

  • ¿Existen todos los archivos de docs/ que son obligatorios para este proyecto? (Depende del tamaño: mira la tabla de la skill /documentacion.)
  • ¿Alguno está vacío — solo comentarios <!-- -->, sin contenido real?
  • ¿Sigue existiendo .template/? Entonces la inicialización quedó a medias.

2. Fichas de feature

Ejecuta la verificación de cobertura y reporta su salida tal cual:

node scripts/verificar-cobertura.mjs

Comprueba las tablas contra docs/prd.md: filas sin validación declarada, excepciones que no explican nada, identificadores inexistentes y tests prometidos que no existen en fichas Verificada. Sus FALLO son FALLO aquí; sus ATENCIÓN son ATENCIÓN.

Añade a mano lo que el script no mira, porque requiere criterio:

  • Fichas en En construcción: son trabajo a medias. Di cuáles y desde cuándo.
  • Tests declarados que existen pero están vacíos o sin aserciones reales. El script solo comprueba que el archivo esté ahí; si te cruzas con uno hueco, es un FALLO aunque la verificación pase.

3. Entorno

  • Versión de Node y de pnpm frente a lo que declare AGENTS.md. Si no coinciden, dilo: la mayoría de fallos raros de instalación son esto.
  • ¿Están las dependencias instaladas (node_modules/)? ¿El lockfile está al día respecto a package.json?
  • Variables: compara los nombres de .env.example con los que hay definidos en el entorno o en .env.local. Reporta solo los nombres que faltan. Nunca imprimas un valor, ni completo ni parcial, ni siquiera para confirmar que es correcto.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
