project-starter-template-es-ai: Skill for Claude Code

.claude/skills/prototipo/SKILL.md

prototipo is a skill for Claude Code from brayandiazc/project-starter-template-es-ai. It costs 95 tokens per session (855 once invoked), scanned A, original, MIT.

A skill for building static, clickable product screens without backend logic. It uses the project's design system and screen map to cover pages such as landing, sign-in, app, legal, and error views.

In plain words
What is it for?
Use it to map and build the product's key screens, including authentication, app flows, legal pages, and error states.
Why use it?
It lets a team check navigation and visual design before implementing server behaviour, while keeping the prototype screens available for later connection.

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

prototipo 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 3d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Construye vistas estáticas clicables — validan flujo y diseño antes de escribir lógica, y luego se conectan (no se tiran).

Paso 1 — Contexto

Lee design/README.md + design/tokens.css (sistema y tokens), el mapa de vistas en docs/architecture/screens.md y el README.md del proyecto. Si no hay mapa de pantallas, constrúyelo primero con la persona. Al terminar, marca en ese mapa las vistas que pasen a estado prototipo.

Paso 2 — Inventario de vistas

Parte del catálogo estándar y márcalo contra el mapa:

  • Públicas: landing/home, precios (si hay pago), sobre/about, contacto, 404 y 500.
  • Legales: términos, privacidad, cookies. La plantilla no trae estos textos — maqueta la estructura de la página y deja el contenido marcado como pendiente.
  • Auth (si hay cuentas): login, registro, recuperar contraseña.
  • App: las vistas propias del recorrido crítico (dashboard, la acción de valor, ajustes/cuenta).

Confirma con la persona cuáles entran en el prototipo (default: todas las del recorrido crítico + landing + legales).

Paso 3 — Construir

Sobre los tokens, no sobre una librería. No hay vistas de ejemplo versionadas a proposito: envejecen y acaban contradiciendo al design system. Se construye con design/tokens.css y primitivas HTML nativas (<dialog>, <details>, popover), que traen foco, teclado y Escape resueltos.

  • Formato según el stack: el sistema de plantillas o de componentes que ya use el proyecto. Si aún no está instanciado, HTML plano importando tokens.css.
  • Si el destino es móvil: la maqueta sirve de spec de contenido y jerarquía, pero el layout, la navegación (tabs, no sidebar) y el catálogo de pantallas son distintos — hay pantallas que solo existen en móvil (onboarding, permisos, sin conexión) y vistas web que no tienen equivalente.
  • Solo tokens semánticos del design system; estados loading/empty/error visibles donde aplique (con datos de ejemplo realistas, no "lorem ipsum").
  • Imágenes/ilustraciones desde las fuentes aprobadas de design/README.md (unDraw, Unsplash, DiceBear…) — optimizadas y con alt.
  • Navegación real entre vistas (links funcionando) — el prototipo se recorre completo.
  • Modo claro y oscuro (prefers-color-scheme + data-theme="dark") y textos para es/en (sin hardcodear cadenas si el preset ya tiene i18n).

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.
