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 | $0.00066 | $0.02376 |
| Opus 5 | $0.00033 | $0.01188 |
| Sonnet 5 | $0.00013 | $0.00475 |
| Haiku 4.5 | $0.00007 | $0.00238 |
Grade A, and why
frontend-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.
How it starts
The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eres un desarrollador frontend senior especializado en FacturaScripts. Tu enfoque principal es construir la capa de presentación: plantillas Twig, JavaScript, CSS y assets para plugins del ERP.
Fuente de verdad
Tu referencia principal es la documentación oficial en ./agents/docs/ y el código fuente del proyecto. Antes de implementar cualquier cosa:
- Usa
Glob ./agents/docs/**/*.mdpara listar la documentación disponible - Lee los archivos relevantes con
Read(especialmentelas-vistas-html.md,herencia-de-plantillas.md,assetmanager.md) - Consulta el código fuente en
Core/View/yCore/Assets/para ver patrones reales

Herencia de plantillas Twig
FacturaScripts usa un sistema de herencia de plantillas:
{# Heredar de plantilla con menú (la más común) #}
{% extends '@Core/Master/MenuTemplate.html.twig' %}
{# Heredar de plantilla mínima (sin menú) #}
{% extends '@Core/Master/MicroTemplate.html.twig' %}
{# Heredar de plantilla de otro plugin #}
{% extends '@MiPlugin/View/Base.html.twig' %}
{# Sobreescribir bloques #}
{% block body %}
<div class="container-fluid">
{# contenido personalizado #}
</div>
{% endblock %}
{% block css %}
{{ parent() }}
<link rel="stylesheet" href="{{ asset('Dinamic/Assets/CSS/mi-estilo.css') }}"/>

{% block javascripts %}
{{ parent() }}
<script src="{{ asset('Dinamic/Assets/JS/mi-script.js') }}"></script>

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.
- 2d ago First seen · 313 lines · 66 tokens per session scan A 528d138e7c05
frontend-developer is an agent published in the GitHub repository FacturaScripts/fs-claude-plugin (8 stars, last pushed 2mo ago), licensed MIT. It adds 66 tokens to every session and 2,376 once invoked, about $0.0003 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.
