Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.01574 |
| Opus 5 | $0.00056 | $0.00787 |
| Sonnet 5 | $0.00022 | $0.00315 |
| Haiku 4.5 | $0.00011 | $0.00157 |
Grade A, and why
leer-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 9d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Leer un contrato
Cuándo usarla
- "saca la cláusula de {clause} de este contrato" (un solo documento).
- "cuáles son los términos de renovación automática en cada contrato de esta carpeta" (por lote).
- "extrae el límite de responsabilidad y el lenguaje de terminación del contrato marco de servicios de {vendor}".
Conexiones que necesito
Ejecuto el trabajo externo a través de Composio. Antes de correr esta habilidad verifico que las categorías de abajo estén vinculadas. Si falta alguna, nombro la categoría, te pido conectarla desde la pestaña de Integraciones y me detengo.
- Archivos (Google Drive) - Obligatorio para corridas por lote y búsquedas por proveedor nombrado. Aquí escaneo carpetas o contratos nombrados.
- Procesamiento de documentos (OCR o extracción de texto de PDF) - Obligatorio. Saca el texto real de PDFs escaneados o nativos para poder extraer las cláusulas textualmente.
Si no hay un proveedor de archivos conectado y no pegaste el contrato, me detengo y te pido conectar Google Drive o pegar el documento.
Información que necesito
Primero leo tu contexto de operaciones. Por cada campo obligatorio que falte hago UNA pregunta en lenguaje simple (mejor modalidad: app conectada > archivo > URL > texto pegado) y espero.
- El contrato en sí - Obligatorio. Por qué lo necesito: no puedo extraer de la nada. Si falta, pregunto: "Comparte el contrato o indícame la carpeta. Sirve un PDF, un Word o un Google Doc."
- Postura frente a proveedores - Obligatorio. Por qué la necesito: me dice qué términos cuentan como advertencia. Una postura conservadora marca con más agresividad que una de riesgo rápido. Si falta, pregunto: "¿Cómo enfrentas los términos con proveedores, conservador, equilibrado o avanzar rápido?"
- Documento de contexto operativo - Obligatorio. Por qué lo necesito: ancla tus líneas rojas para poder marcar cláusulas que las violarían. Si falta, pregunto: "¿Quieres que primero configure tu contexto operativo? Me ayuda a detectar términos desfavorables con más confianza."
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.

leer-un-contrato is a skill published in the GitHub repository gethouston/houston (113 stars, last pushed yesterday), licensed MIT. It adds 112 tokens to every session and 1,574 once invoked, about $0.0006 per session on Opus 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 2026-09-03.
