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

revisar-un-contrato 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 13d 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.

Revisar un contrato

Una sola skill para la primera lectura de un contrato de contraparte. mode elige la profundidad. Comparte la extracción estructurada de cláusulas y la disciplina de "nunca inventar un estándar de cláusula que no pueda citar".

Parámetro: mode

  • full: revisión completa de MSA / DPA / formulario de pedido: mapa de cláusulas + veredicto por cláusula Verde (aceptar) / Amarillo (objeción opcional) / Rojo (objeción obligatoria) + resumen en español sencillo + recomendación de aceptar / objetar / retirarse. Escribe en contract-reviews/{counterparty}-{YYYY-MM-DD}.md.
  • nda-traffic-light: rúbrica rápida de 6 dimensiones para NDAs entrantes (plazo, mutualidad, definición de información confidencial, excepciones, jurisdicción, no-solicitud encubierta, devolución/destrucción). Escribe en ndas/{counterparty-slug}-{YYYY-MM-DD}.md con objeciones específicas en cada punto Rojo.
  • clauses-only: extracción estructurada, sin veredicto. Lee el contrato suministrado (archivo / URL / texto pegado), extrae las cláusulas que importan (plazo, terminación, renovación, tope de responsabilidad, indemnización, propiedad intelectual, ley aplicable, DPA, entrenamiento de IA, residencia de datos, derechos de salida), escribe un mapa legible en clause-extracts/{counterparty}-{YYYY-MM-DD}.md, actualiza counterparty-tracker.json con los campos clave.

Si el usuario nombra el modo en lenguaje sencillo ("hazle semáforo a esto", "solo extrae las cláusulas", "revisión completa con veredicto") → infiere. Si es ambiguo → haz UNA pregunta nombrando las 3 opciones.

Cuándo usarlo

  • Explícito: "revisa este contrato", "hazle semáforo a este NDA", "¿se puede firmar?", "qué dice este acuerdo", "extrae las cláusulas".
  • Las solicitudes en lenguaje sencillo se traducen a un mode: "revisa completo este contrato de cliente / MSA" / "¿es seguro firmar este MSA?" → full; "revisión rápida de este NDA" / "¿está bien firmar este NDA?" → nda-traffic-light; "solo muéstrame las cláusulas" / "extrae las cláusulas, sin veredicto" / "revisa la cláusula de propiedad intelectual" (ejecuta full y encabeza con la sección de propiedad intelectual) → clauses-only o full con foco en propiedad intelectual.
  • Implícito: llamado por sort-my-legal-inbox cuando detecta un MSA / NDA / DPA y lo dirige a revisión. Se encadena con plan-contract-pushback cuando el resultado tiene algún punto Rojo.
