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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00095 | $0.00855 |
| Opus 5.5 | $0.00038 | $0.00342 |
| Sonnet 5.5 | $0.00019 | $0.00171 |
| Haiku 4.5 | $0.00010 | $0.00085 |
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 1mo 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 conalt. - 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.
- 1mo ago First seen · 64 lines · 95 tokens per session scan A 81b9c0476f5c
prototipo is a skill published in the GitHub repository brayandiazc/project-starter-template-es-ai (15 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 855 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-08.
