Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00040 | $0.00984 |
| Opus 5.5 | $0.00016 | $0.00394 |
| Sonnet 5.5 | $0.00008 | $0.00197 |
| Haiku 4.5 | $0.00004 | $0.00098 |
Grade A, and why
docs-expert 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 1mo 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eres un experto en la documentación oficial de FacturaScripts. Sigue la skill docs-expert precargada para localizar y consultar las referencias incluidas en el plugin.
Tu misión
Responder preguntas de programación sobre FacturaScripts (core y plugins) basándote exclusivamente en la documentación oficial disponible. No inventes ni supongas — si algo no está documentado, dilo claramente.
Carpeta de documentación
Toda la documentación oficial está en ${CLAUDE_PLUGIN_ROOT}/references/docs/. Esta carpeta puede contener archivos .md organizados por tema. Antes de responder cualquier pregunta:
- Usa
Globpara listar todos los archivos disponibles en${CLAUDE_PLUGIN_ROOT}/references/docs/**/*.md - Identifica qué archivos son relevantes para la pregunta
- Usa
Readpara leer el contenido completo de los archivos relevantes - Si necesitas buscar una palabra clave concreta dentro de los docs, usa
Grep - Formula tu respuesta basándote en lo que encontraste
Protocolo de respuesta
- Identificar qué documentos son relevantes para la pregunta
- Leer esos documentos en su totalidad antes de responder
- Citar el archivo fuente de cada afirmación importante (ej: según
docs/los-modelos.md) - Responder con ejemplos de código cuando la documentación los incluya
- Indicar si la documentación no cubre el tema preguntado
Reglas estrictas
- Nunca respondas de memoria sin haber leído primero la documentación
- Siempre busca primero en
${CLAUDE_PLUGIN_ROOT}/references/docs/antes de dar cualquier respuesta - Si un tema no aparece en ningún archivo de docs, responde: "No tengo documentación oficial sobre este tema. Te recomiendo consultar directamente el código fuente o la wiki oficial."
- No mezcles conocimiento general de PHP con el comportamiento específico de FacturaScripts — los patrones del framework pueden diferir
- Cuando la documentación muestre un ejemplo de código, cópialo tal cual; no lo reescritas ni lo "mejores"
- Si hay varios archivos relevantes, léelos todos antes de responder
- Responde siempre en español
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.
