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 | $0.00151 | $0.02448 |
| Opus 5 | $0.00076 | $0.01224 |
| Sonnet 5 | $0.00030 | $0.00490 |
| Haiku 4.5 | $0.00015 | $0.00245 |
Grade A, and why
gestor-autonomos 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 12d 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 — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gestor de Autónomos España
Skill para gestión contable y fiscal de trabajadores autónomos en España con cálculos matemáticamente precisos.
[!CAUTION] ADVERTENCIA: Esta skill es una herramienta de apoyo y no sustituye el asesoramiento profesional. Los cálculos y sugerencias generados deben ser revisados por un gestor o profesional cualificado. El uso de esta herramienta se realiza bajo la responsabilidad exclusiva del usuario. Mafia Claude Skills y sus contribuidores no se hacen responsables de errores en las declaraciones fiscales o sanciones derivadas de su uso.
Principios fundamentales
- Precisión matemática obligatoria: SIEMPRE usar los scripts de Python para cualquier cálculo. NUNCA calcular mentalmente.
- Base legal: Todas las operaciones siguen la normativa de la AEAT (Agencia Tributaria).
- Verificación doble: Cada cálculo debe ser verificable y trazable.
Workflow principal
Paso 1: Identificar el tipo de operación
¿Qué necesita el usuario?
- Calcular IVA trimestral → Ejecutar

Paso 2: Recopilar datos
Solicitar al usuario la información necesaria según la operación:
Para IVA trimestral:
- Facturas emitidas (base imponible + IVA repercutido)
- Facturas recibidas deducibles (base imponible + IVA soportado)
- Trimestre (1T, 2T, 3T, 4T) y año
Para IRPF (Modelo 130):
- Ingresos del trimestre (sin IVA)
- Gastos deducibles del trimestre (sin IVA)
- Retenciones practicadas por clientes
- Pagos fraccionados anteriores del año
Para facturas:
- Número de factura
- Fecha
- NIF/CIF del cliente/proveedor
- Concepto
- Base imponible
- Tipo de IVA aplicable
- Retención IRPF (si aplica)
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
