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 | $0.00054 | $0.00335 |
| Opus 5.5 | $0.00022 | $0.00134 |
| Sonnet 5.5 | $0.00011 | $0.00067 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
cobros 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
Cobros pendientes
Antes de usar herramientas, lee las reglas de Frihet y el flujo de cobros. Si Frihet no está conectado, indica el paso de conexión sin pedir credenciales.
Obtén una cartera verificable a la fecha de corte: recorre todas las páginas, comprueba el saldo después de pagos y abonos y agrupa por moneda. Para importes aportados por el usuario, identifica la procedencia y los datos que faltan; no afirmes que has consultado Frihet si no lo has hecho.
Entrega una tabla con factura, cliente, vencimiento, días vencidos, saldo y moneda. Separa lo vencido de lo todavía no vencido. Muestra saldos desconocidos y cobertura parcial. Propón prioridades dentro de cada moneda y redacta recordatorios cuando se soliciten. No escales automáticamente a amenazas o reclamaciones legales.
Un informe o un borrador de recordatorio no autoriza envíos, marcas de pago, conciliaciones, devoluciones ni cambios en clientes. Para enviar, comprueba el contenido y destinatario con el usuario y la capacidad real de la herramienta.
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.
