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 | $0.00055 | $0.00302 |
| Opus 5.5 | $0.00022 | $0.00121 |
| Sonnet 5.5 | $0.00011 | $0.00060 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
revision-mensual 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.
What it actually says
Revisión mensual
Antes de usar herramientas, lee las reglas de Frihet y el flujo mensual.
Define el periodo y la empresa. Revisa resúmenes y registros disponibles, páginas, moneda y significado de cada importe. No mezcles borradores con facturación emitida, facturado con cobrado ni total original con saldo después de pagos parciales. Identifica abonos, cancelaciones y gastos pendientes de validar.
Entrega un resumen por moneda con facturado, cobrado, pendiente y gastos solo cuando se puedan comprobar. Incluye la cobertura, los registros de origen, incidencias y siguientes acciones propuestas. Si faltan páginas o justificantes, indica que la revisión es parcial; no declares que el mes está cerrado.
No ejecutes conciliaciones, cambios de estado, recurrencias ni presentaciones fiscales como parte de una revisión. Solicita una instrucción concreta cuando el usuario decida realizar una de las acciones propuestas.
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.
