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 | $0.00078 | $0.01839 |
| Opus 5 | $0.00039 | $0.00920 |
| Sonnet 5 | $0.00016 | $0.00368 |
| Haiku 4.5 | $0.00008 | $0.00184 |
Grade A, and why
planear-un-viaje 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planear un viaje
Cuándo usarla
- "voy a {city}" / "planea mi viaje a {X}" / "planea un viaje de principio a fin".
- "vuelos para {conference}" / "tengo una visita a cliente en {X}".
- "arma mi paquete de viaje".
Conexiones que necesito
Ejecuto todo el trabajo externo a través de Composio. Antes de ejecutar esta skill 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.
- Calendario (Google Calendar, Outlook) - Requerido. Me permite ver las reuniones existentes durante la ventana del viaje y extraer eventos en el destino.
- Bandeja de entrada (Gmail, Outlook) - Opcional. Me ayuda a encontrar confirmaciones de reserva o itinerarios existentes.
- Proveedores de viaje (búsqueda de vuelos u hoteles) - Opcional. Si están conectados muestro opciones reales; si no, escribo los criterios de búsqueda y tú reservas por tu cuenta.
Si no hay calendario conectado, me detengo y te pido conectar primero tu calendario.
Información que necesito
Primero leo tu contexto de operaciones. Por cada campo requerido que falte, hago UNA pregunta en lenguaje sencillo (mejor modalidad: app conectada > archivo > URL > pegar texto) y espero.
- Destino y fechas - Requerido. Por qué lo necesito: nada funciona sin el dónde y el cuándo. Si falta, pregunto: "¿A dónde vas y en qué fechas? Un rango sirve si todavía tienes flexibilidad."
- Propósito del viaje - Requerido. Por qué lo necesito: una visita a cliente, una conferencia, un offsite y un viaje personal reciben itinerarios y listas de equipaje distintos. Si falta, pregunto: "¿Cuál es el propósito del viaje: visita a cliente, conferencia, offsite o personal?"
- Preferencias de viaje - Requerido. Por qué las necesito: redacto según tus preferencias reales en vez de adivinar. Si faltan, pregunto: "¿Cuáles son tus preferencias de viaje: aerolínea preferida, asiento, cadena de hoteles, necesidades alimentarias, algo que siempre deba incluir?"
- Tu zona horaria - Opcional. Por qué la necesito: detecta conflictos de agenda durante la ventana del viaje. Si no la tienes, sigo adelante con TBD usando el valor predeterminado de tu contexto operativo.
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.

planear-un-viaje is a skill published in the GitHub repository gethouston/houston (113 stars, last pushed today), licensed MIT.
