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

calendario-aeat 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 13d 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.

Calendario de Obligaciones Fiscales AEAT

Propósito

Generar mensualmente el calendario de obligaciones tributarias de la entidad ante la Agencia Estatal de Administración Tributaria (AEAT) y, en su caso, las haciendas forales o autonómicas. Permite al equipo fiscal y contable planificar con antelación la preparación y presentación de declaraciones, evitando recargos por presentación extemporánea.

Fuentes

  • Calendario del contribuyente de la AEAT (publicación anual)
  • Perfil fiscal de la entidad: forma jurídica, régimen IVA, obligaciones específicas
  • Modelos tributarios aplicables a la entidad
  • Registro de presentaciones anteriores (modelo, período, fecha, resultado)
  • Calendario de festivos nacionales y autonómicos (afecta a plazos)
  • Haciendas forales aplicables (País Vasco, Navarra) si procede

Flujo de trabajo

  1. Cargar el perfil fiscal de cada entidad gestionada
  2. Identificar los modelos tributarios a presentar en el mes en curso:
    • Autoliquidaciones mensuales: Modelo 303 (IVA), 111 (retenciones IRPF), 115 (retenciones alquileres), 123 (retenciones capital mobiliario)
    • Autoliquidaciones trimestrales (si aplica): mismos modelos para pymes
    • Declaraciones informativas: 347, 349, 720, etc.
    • Pagos fraccionados: Modelo 202 (IS), 130/131 (IRPF)
    • Impuesto sobre Sociedades: Modelo 200 (julio, plazo 25 días tras 6 meses)
    • Cuentas anuales e IS: coordinar con módulo societario
  3. Para cada obligación: a. Verificar el plazo exacto de presentación (día del mes) b. Comprobar si hay aplazamientos o fraccionamientos vigentes c. Verificar el estado de preparación (datos disponibles, borrador, revisado) d. Calcular días restantes hasta el vencimiento
  4. Generar el calendario mensual con todas las obligaciones

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.
