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

brecha 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 17d 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/brecha

  1. Leer ~/.claude/plugins/config/claude-para-abogados/proteccion-datos/CLAUDE.md — perfil de práctica.
  2. Evaluar el incidente según la tipología y gravedad.
  3. Determinar obligaciones de notificación.
  4. Generar checklist de acciones y plantillas.

Propósito

Guiar la respuesta inmediata ante una brecha de seguridad de datos personales, asegurando el cumplimiento de los plazos legales (72 horas para notificar a la AEPD) y la correcta evaluación del riesgo para los interesados.

URGENCIA: El reloj corre

72 horas desde que se tiene conocimiento de la brecha para notificar a la AEPD si existe riesgo para los derechos y libertades (art. 33.1 RGPD). Si se supera el plazo, hay que justificar el retraso. La AEPD considera que "tener conocimiento" es el momento en que el responsable tiene certeza razonable de que se ha producido un incidente de seguridad que afecta a datos personales.

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.
