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 | $0.00110 | $0.04104 |
| Opus 5 | $0.00055 | $0.02052 |
| Sonnet 5 | $0.00022 | $0.00821 |
| Haiku 4.5 | $0.00011 | $0.00410 |
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.
How it starts
The opening of the file, as written. The whole thing — 484 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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
Tablas de documentos
| Documento | Tabla cabecera | Tabla líneas |

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.
- 2d ago First seen · 484 lines · 110 tokens per session scan A 2acfc2fbee04
document-expert is an agent published in the GitHub repository FacturaScripts/fs-claude-plugin (8 stars, last pushed 2mo ago), licensed MIT. It adds 110 tokens to every session and 4,104 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
