accessibility-audit

accessibility-audit is a skill for Claude Code, Codex from Nordic-AI/production-readiness-skills. It costs 167 tokens per session (5,782 once invoked), scanned A, original, Apache-2.0.

A review of whether people with disabilities can use a web or application interface, based on WCAG 2.2 Level AA and, where relevant, the European Accessibility Act. WCAG is a set of accessibility guidelines for digital products.

In plain words
What is it for?
Use it to check semantic HTML, ARIA, keyboard navigation, focus behavior, color contrast, screen-reader support, form labels and errors, alternative text, and motion.
Why use it?
It finds barriers that can stop people using keyboards, screen readers, forms, or visual interfaces, and can also reveal legal obligations for products sold in the EU.

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

accessibility-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 12d 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 — 478 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Accessibility Audit

You review the application's accessibility — whether people with disabilities can use it. The standard is WCAG 2.2 Level AA; for products sold in the EU, the European Accessibility Act (EAA) makes this legally required from June 2025 for a broad category of products and services.

This skill follows the library-wide rules in docs/CONVENTIONS.md. Read that first.

Scope

Applies whenever the application has a user interface — web, mobile web, desktop Electron, native mobile if the codebase is visible. Does not apply to backend-only services or internal CLIs (but see release-readiness for operator tooling).

Inputs

From orchestrator: scope_tier, jurisdiction, stack_summary, gitnexus_indexed. Plus:

  • ui_framework: react | vue | angular | svelte | ember | plain-html | ios-native | android-native | flutter | other
  • target_wcag_level: A | AA | AAA (default AA)
  • eaa_in_scope: true | false — does the product fall under the EAA? (e-commerce, banking, transport tickets, e-books, computing hardware + OS, telecoms, AV media services, ATMs, etc.)

If not provided, ask.

Finding ID prefix

A11Y — see CONVENTIONS.md §4.

Review surface

1. Semantic HTML

Semantic elements carry accessibility for free. Misused <div>/<span> is the most common accessibility failure.

  • <button> for clickable actions, not <div onClick>. The former is keyboard-focusable, has proper role, fires on Enter/Space.
  • <a href> for navigation, not <button> or <div> with onClick={() => navigate(...)}.
  • Landmark elements: <header>, <nav>, <main>, <aside>, <footer> — one <main> per page.
  • Heading hierarchy <h1><h6> with no skips.
  • Form structure: <label for> tied to <input id>, <fieldset> + <legend> for grouped inputs.
  • Lists: <ul> / <ol> for lists, not series of <div>.
  • Tables: <table> with <thead>, <tbody>, <th scope> for data tables. Never for layout.
  • <dialog> for modal dialogs (or well-implemented ARIA dialog pattern), not just a styled <div>.

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.
