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.

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 | $0.00131 | $0.00566 |
| Opus 5 | $0.00066 | $0.00283 |
| Sonnet 5 | $0.00026 | $0.00113 |
| Haiku 4.5 | $0.00013 | $0.00057 |
Grade A, and why
fullstack-developer 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 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.
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.
What it actually says
Skill: fullstack-developer — Desarrollo fullstack de FacturaScripts
Esta skill conecta las peticiones de desarrollo completo del usuario con el agente
fullstack-developer, que sabe crear funcionalidades end-to-end manteniendo coherencia
entre todas las capas del framework.
Por qué usar el agente
El agente fullstack-developer garantiza que todas las capas (tabla XML, modelo PHP,
controlador, XMLView, Init.php, traducciones) están correctamente conectadas y siguen las
convenciones de nombres de FacturaScripts. Crear cada capa por separado introduce riesgo
de inconsistencias (nombres de campos, tipos de datos, convenciones de naming).
Cómo invocar el agente
Agente: fullstack-developer
Tarea: [descripción exacta de la funcionalidad completa]
El agente:
- Planifica la arquitectura completa (modelo, controlador, vista)
- Consulta la documentación para verificar patrones
- Crea todos los archivos necesarios en orden lógico
- Verifica la coherencia entre capas
- Crea traducciones y actualiza Init.php

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.

fullstack-developer is a skill published in the GitHub repository FacturaScripts/fs-claude-plugin (8 stars, last pushed 2mo ago), licensed MIT. It adds 131 tokens to every session and 566 once invoked, about $0.0007 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 2026-08-31.
