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

seo-audit 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 4d 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.

What it actually says

Audita los metadatos SEO de la página/ruta que indique la persona.

  1. Lee docs/conventions/seo.md para conocer las tags requeridas del proyecto, los formatos de valor (p. ej. longitud del title, longitud de la description), las reglas por tipo de página y qué páginas deben indexarse frente a noindex.
  2. Identifica los archivos fuente de la página/ruta y dónde se define su metadata.
  3. Verifica cada ítem requerido frente al documento de convenciones:
    • <title> — presente, único, dentro de la regla de longitud.
    • meta description — presente, dentro de la longitud, descriptiva.
    • URL canónica — presente y correcta.
    • Open Graph / tags sociales — og:title, og:description, og:image, etc. según se requiera.
    • directivas robots — correctas para este tipo de página (p. ej. noindex en páginas privadas/utilitarias).
    • Datos estructurados, si la convención lo requiere.
  4. Produce un informe en forma de lista de verificación: cada ítem marcado como Presente / Falta / Incorrecto, con el archivo:línea y una sugerencia concreta de corrección para cada problema.

Ejemplo de hallazgo: Falta canonical — añádelo a app/pricing/page.tsx; la convención exige uno en cada página indexable.

NO reescribas la metadata de forma silenciosa a menos que la persona lo pida — informa primero los hallazgos. Da siempre prioridad a docs/conventions/seo.md por encima de consejos genéricos de SEO.

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.
