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 | $0.00058 | $0.00989 |
| Opus 5 | $0.00029 | $0.00495 |
| Sonnet 5 | $0.00012 | $0.00198 |
| Haiku 4.5 | $0.00006 | $0.00099 |
Grade A, and why
accessibility-wcag 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 11d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accesibilidad — WCAG 2.2 AA
Cuándo usar
- Cualquier UI con la que interactúe una persona.
- Antes de mergear un PR que toca componentes interactivos.
- Auditoría de una pantalla existente.
Principios POUR
- Perceivable — todo contenido tiene alternativa textual o auditiva.
- Operable — todo se puede usar con teclado, sin tiempo límite duro.
- Understandable — lenguaje claro, errores con instrucción.
- Robust — válido sintácticamente, compatible con asistivas.
Semántica primero
Antes de ARIA, HTML nativo:
| Necesitás | Usá | No uses |
|---|---|---|
| Botón clickeable | <button> |
<div onClick> |
| Link | <a href> |
<button> que navega |
| Lista | <ul>/<ol> |
<div> con bullets |
| Encabezado | <h1>..<h6> jerárquico |
<div class="title"> |
| Formulario | <form> + <label for> |
inputs sueltos |
| Tabla de datos | <table> con <th> y scope |
grid de <div> |
| Diálogo modal | <dialog> |
<div> flotante |
ARIA solo cuando el HTML nativo no alcanza. No ARIA es mejor que ARIA mal.

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.
