Token cost

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.

Security

Grade A, and why

revision 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.

/revision

  1. Cargar ~/.claude/plugins/config/claude-para-abogados/fiscal/CLAUDE.md → tipo de entidad, régimen, criterios.
  2. Obtener los datos de la declaración.
  3. Ejecutar las comprobaciones de coherencia.
  4. Marcar discrepancias.
  5. Generar informe de revisión.
/fiscal:revision
Modelo 303 del 2T 2026: IVA devengado 45.000 EUR, IVA soportado deducible
52.000 EUR, resultado a compensar 7.000 EUR.

Propósito

Una declaración tributaria incoherente internamente o con otras declaraciones del mismo período es una señal roja para la AEAT. Este skill ejecuta las comprobaciones cruzadas habituales que un buen asesor fiscal realiza antes de presentar: ¿cuadran los números entre modelos? ¿hay discrepancias que la AEAT detectará automáticamente?


Comprobaciones por modelo

Modelo 303 (IVA)

Comprobación Cruce Discrepancia típica
IVA devengado vs libro de facturas emitidas Base imponible × tipo = cuota repercutida Error en tipo aplicado o base
IVA soportado deducible vs libro de facturas recibidas Solo deducible si cumple requisitos art. 92-100 LIVA Facturas no deducibles incluidas
Prorrata Si aplica: ¿se ha aplicado correctamente el % de prorrata? Error en cálculo de prorrata
Operaciones no sujetas / exentas ¿Se han declarado correctamente en las casillas correspondientes? Operaciones mal clasificadas
Coherencia 303 ↔ 390 Suma de los 303 del año = 390 Diferencias por regularizaciones no cuadradas
Coherencia 303 ↔ 349 Operaciones intracomunitarias del 303 = las del 349 Operaciones no declaradas en uno u otro

Modelo 111 / 190 (Retenciones)

Comprobación Cruce Discrepancia típica
Retenciones practicadas vs declaradas Nóminas + facturas profesionales → mod. 111 Retención mal calculada o no declarada
Coherencia 111 ↔ 190 Suma de los 111 del año = 190 Perceptor no incluido en el resumen anual
Retenciones ↔ certificados emitidos Lo retenido = lo certificado al perceptor Discrepancia genera incidencia al perceptor

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.
