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 5.1 | $0.00021 | $0.02190 |
| Opus 5 | $0.00010 | $0.01095 |
| Sonnet 5 | $0.00004 | $0.00438 |
| Haiku 4.5 | $0.00002 | $0.00219 |
Grade A, and why
configure-local-modules 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 7d 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Configurar Módulos Locales Privados
Este skill configura la ruta de módulos MCP privados en ~/.fs-claude.json (el archivo de configuración unificado de fs-claude), y te guía para crear módulos nuevos.
¿Para qué sirve?
Los módulos locales son herramientas MCP que solo tú usas — endpoints privados de tu empresa, integraciones con otros sistemas, o tools específicas de tu instalación de FacturaScripts. Se almacenan en tu máquina y nunca se suben a GitHub.
Cómo funciona
El servidor MCP lee settings.localModulesPath de ~/.fs-claude.json al arrancar. Si la ruta existe, carga automáticamente todos los módulos dentro. No requiere configuración de variables de entorno.
Pasos para configurar
1. Detectar la configuración actual
Ejecuta este comando para saber si ya tienes una ruta configurada:
import json
from pathlib import Path
fs_claude = Path.home() / '.fs-claude.json'
if fs_claude.exists():
config = json.loads(fs_claude.read_text(encoding='utf-8'))
path = config.get('settings', {}).get('localModulesPath', '')
print(f"Ruta configurada: {path}" if path else "Sin ruta configurada")
else:
print("~/.fs-claude.json no existe aún")
2a. Si ya hay una ruta configurada
Usa esa ruta directamente. Confirma al usuario que el servidor MCP la cargará al reiniciar y muestra su contenido actual.
2b. Si NO hay ruta configurada
Pregunta al usuario si quiere:
- Usar una carpeta existente: proporciona la ruta absoluta
- Crear la carpeta por defecto: se crea
~/fs-claude-mcp-private/automáticamente
Para crear la carpeta por defecto y registrarla:
import json
from pathlib import Path
fs_claude = Path.home() / '.fs-claude.json'
modules_dir = Path.home() / 'fs-claude-mcp-private'
# Crear el directorio si no existe
modules_dir.mkdir(exist_ok=True)
print(f"Carpeta creada: {modules_dir}")
# Actualizar ~/.fs-claude.json
config = json.loads(fs_claude.read_text(encoding='utf-8')) if fs_claude.exists() else {
"version": "1.0",
"connections": {"default": "", "connections": {}},
"settings": {"sortClassMembers": True, "updateCopyright": True}
}
config.setdefault('settings', {})['localModulesPath'] = str(modules_dir)
fs_claude.write_text(json.dumps(config, indent=2, ensure_ascii=False), encoding='utf-8')
print(f"Ruta guardada en: {fs_claude}")
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.

configure-local-modules is a skill published in the GitHub repository FacturaScripts/fs-claude-plugin (8 stars, last pushed 4d ago), licensed MIT. It adds 21 tokens to every session and 2,190 once invoked, about $0.0001 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.
