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 | $0.00096 | $0.00494 |
| Opus 5 | $0.00048 | $0.00247 |
| Sonnet 5 | $0.00019 | $0.00099 |
| Haiku 4.5 | $0.00010 | $0.00049 |
Grade A, and why
rc-a11y 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 10d 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
Acessibilidade (a11y) — guias por tarefa
Guias práticos de acessibilidade web. Leia o guia da tarefa em references/ antes de agir —
cada um traz o checklist, os exemplos de markup e os critérios de aceite. Ao revisar UI real,
combine com Grep/Glob para inspecionar o markup/componentes gerados; não presuma a semântica.
Roteamento
| Tarefa | Guia |
|---|---|
| Fundamentos — HTML semântico, WCAG POUR, nível AA, alt text, lang | references/foundations.md |
| Componentes interativos — formulários, modal, menus/tabs, foco/teclado | references/patterns.md |
| Teste e revisão — teclado, leitor de tela, ferramentas automáticas, contraste | references/testing.md |
Princípios sempre válidos
- HTML semântico primeiro. Elemento nativo (
<button>,<nav>,<label>) resolve a maioria dos casos antes de qualquer ARIA. - ARIA só quando o HTML nativo não resolve. "No ARIA is better than bad ARIA" — ARIA incorreta é pior que ausência de ARIA.
- Tudo operável por teclado. Se uma ação só funciona com mouse/toque, é um bloqueador de acessibilidade.
- Contraste e foco visíveis. Cor não é o único indicador de estado;
:focus-visiblesempre perceptível.
Error Handling
- SPA renderizada no cliente pode esconder problemas do leitor de tela (DOM que só existe após JS rodar). Sem acesso ao browser, revise o markup/componentes estaticamente e diga explicitamente que a verificação com screen reader/axe ficou pendente.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rc-a11y is a skill published in the GitHub repository rodolfochicone/rc-project (19 stars, last pushed 1mo ago), licensed MIT. It adds 96 tokens to every session and 494 once invoked, about $0.0005 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 2026-08-30.
