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 B, and why

api-docs-writer scanned grade B with 2 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

response = requests.post( "https://api.example.com/v1/endpoint",

Not a fault in itself. Listed so you know the mod talks to something, and to what.

API Docs Writer Skill

Esta skill transforma especificaciones de API crudas, descripciones de endpoint o colecciones Postman en documentación limpia y orientada a desarrolladores, siguiendo convenciones adyacentes a OpenAPI. El resultado está listo para un portal de desarrolladores, README o página en Notion/Confluence.

Inputs Requeridos

Trabaja con lo que se proporciona. Si falta alguno de estos, aun así produce el output completo: llena cada brecha con una suposición razonable marcada como (assumed, confirm) y lista esas suposiciones al final. Haz una pregunta solo cuando el tema central en sí falte (no hay nada sobre qué escribir).

  • Detalles de API o endpoint (especificación cruda, export de Postman o descripción verbal)
  • Método de autenticación (API key / Bearer token / OAuth 2.0 / Ninguno)
  • URL base
  • Versión de API (p. ej. v1, v2.3, o "sin versionar" — afecta notas de deprecación y headers de versionado)
  • Rate limits (requests por segundo/minuto por token o IP, si se conoce — o "desconocido")
  • Audiencia (desarrolladores internos / partners externos / público)
  • Formato de output (Markdown para portales de desarrolladores y READMEs / Prosa plana para Confluence o Notion — nota: OpenAPI YAML no es producido por esta skill)

Formato de Output

Para cada endpoint, produce lo siguiente:


[METHOD] /path/to/endpoint

Summary: [Una línea — qué hace este endpoint]

Description: [2–4 oraciones. Cuándo usar este endpoint. Qué devuelve. Cualquier comportamiento importante a conocer (paginación, rate limits, procesamiento asincrónico, etc.)]

Authentication: [Requerida / Opcional — método]


Request

Headers:

Header Requerido Descripción
Authorization Sí Bearer <token>
Content-Type Sí application/json

Path Parameters:

Parámetro Tipo Requerido Descripción
id string Sí Identificador único para el recurso

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.
