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.

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

document-expert 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 2d 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.

Conocimiento del framework

Arquitectura de documentos

FacturaScripts gestiona documentos de negocio en dos cadenas paralelas:

Cadena de ventas (cliente):

PresupuestoCliente → PedidoCliente → AlbaranCliente → FacturaCliente

Cadena de compras (proveedor):

PresupuestoProveedor → PedidoProveedor → AlbaranProveedor → FacturaProveedor

Cada documento tiene:

  • Cabecera (BusinessDocument) — Datos generales: cliente, fecha, serie, almacén, totales
  • Líneas (BusinessDocumentLine) — Detalle: producto, cantidad, precio, impuesto, descuento

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.
