a11y-audit is a skill for Claude Code, Codex from ricneves-ai/flowgrammers-skills. It costs 93 tokens per session (2,827 once invoked), scanned A, original, MIT.

A web-accessibility audit skill for React, Next.js, Vue, Angular, Svelte, and plain HTML codebases. It checks WCAG 2.2 Level A and AA requirements, which are guidelines for making websites usable by people with disabilities.

In plain words
What is it for?
Use it to scan websites, fix issues such as contrast problems, verify accessibility changes, generate reports, and prevent new accessibility violations in CI/CD.
Why use it?
It finds accessibility problems, provides framework-specific correction code, and checks whether fixes resolve the original issues without regressions. It can also produce structured compliance reports and pipeline checks.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/a11y_scanner.py /path/to/project.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

a11y-audit 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 9d 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.

Auditoria de Acessibilidade

Skill de Auditoria e Remediação de Acessibilidade WCAG 2.2

Descrição

A skill a11y-audit fornece um pipeline completo de auditoria de acessibilidade para aplicações web modernas. Implementa um fluxo de trabalho em três fases — Escanear, Corrigir, Verificar — que identifica violações WCAG 2.2 Nível A e AA, gera código de correção preciso por framework e produz relatórios de conformidade prontos para partes interessadas.

Para cada violação encontrada, fornece o código de correção preciso antes/depois, adaptado ao seu framework (React, Next.js, Vue, Angular, Svelte ou HTML puro).

O que esta skill faz:

  1. Escaneia seu codebase em busca de todas as violações WCAG 2.2 Nível A e AA, categorizadas por severidade (Crítica, Maior, Menor)
  2. Corrige cada violação com padrões de código antes/depois específicos para o framework
  3. Verifica que as correções resolvem as violações originais e não introduzem regressões
  4. Reporta os resultados em formato estruturado adequado para desenvolvedores, PMs e partes interessadas em conformidade
  5. Integra em pipelines CI/CD para prevenir regressões de acessibilidade

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.
