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

architecture-decision-record 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 2d 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.

Habilidad de Registro de Decisión de Arquitectura (ADR)

Esta habilidad produce un Registro de Decisión de Arquitectura (ADR) completo siguiendo el formato Nygard — el estándar más ampliamente adoptado. Los ADRs documentan el razonamiento detrás de decisiones técnicas significativas para que los futuros miembros del equipo entiendan no solo qué se decidió, sino por qué.

Inputs Requeridos

Trabaja con lo que se proporciona. Si falta algo de esto, aun así produce el resultado completo: rellena cada vacío con una suposición razonable marcada como (asumido, confirmar) y lista esas suposiciones al final. Solo haz una pregunta cuando falta el tema central en sí (no hay nada sobre lo que escribir).

  • Número de ADR (número secuencial en tu registro de ADR — p. ej. 012; o "siguiente disponible" si es desconocido)
  • Título de la decisión (breve, p. ej. "Usar PostgreSQL como almacén de datos principal")
  • Contexto (¿qué situación llevó a que esta decisión fuera necesaria?)
  • Opciones consideradas (al menos 2; si solo se da 1, solicita alternativas que fueron consideradas o descartadas)
  • Decisión tomada (qué opción fue elegida)
  • Razón de la elección
  • Estado (Propuesto / Aceptado / Deprecado / Reemplazado)
  • Autor y fecha
  • Contexto del equipo (opcional — tamaño del equipo, experiencia relevante, restricciones organizacionales; ayuda a calibrar la formalidad y profundidad de la sección de Contexto)

Formato de Salida


ADR-[NNN]: [Título de la Decisión]

Fecha: [YYYY-MM-DD] Estado: [Propuesto / Aceptado / Deprecado / Reemplazado por ADR-NNN] Autor(es): [Nombre(s)] Responsables de la decisión: [Quién tuvo la palabra final — individuo o equipo]


Contexto

[3–6 oraciones. Describe la situación, restricciones y fuerzas en juego que hicieron necesaria esta decisión. Incluye: el problema a resolver, estado relevante del sistema, restricciones del equipo, presiones de cronograma o requisitos innegociables. Escribe como si explicaras a alguien que se une al equipo 18 meses después sin contexto previo.]

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.
