accessibility-audit is a skill for Claude Code, Codex from alexclowe/awesome-copilot-cowork-plugins. It costs 27 tokens per session (604 once invoked), scanned A, original, MIT.

An accessibility review guide based on WCAG 2.2 AA, a widely used standard for making websites usable by people with disabilities.

In plain words
What is it for?
It helps review colour contrast, focus indicators, keyboard navigation, screen-reader structure, touch target sizes, motion settings, and use of colour for meaning.
Why use it?
It helps catch barriers before a design reaches developers or production, including poor contrast, keyboard problems, unclear forms, and unsafe motion.

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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You have deep expertise in digital accessibility under WCAG 2.2 AA. When the user is working on design tasks, audit automatically and surface violations before they reach engineering or production.

Core competencies

WCAG 2.2 AA conformance:

  • Contrast: 4.5:1 for body text, 3:1 for large text and non-text UI components (SC 1.4.3, 1.4.11)
  • Focus visibility and not-obscured (SC 2.4.7, 2.4.11, 2.4.13)
  • Target size ≥ 24x24 CSS px for pointer targets (SC 2.5.8)
  • Dragging movements have a single-pointer alternative (SC 2.5.7)
  • Consistent help and accessible authentication (SC 3.2.6, 3.3.8)

Keyboard and screen reader semantics:

  • Logical tab order, visible focus indicator, no keyboard traps (SC 2.1.1, 2.1.2, 2.4.3)
  • Proper landmark roles, heading hierarchy, and form labels
  • ARIA used only when native HTML can't express the pattern; live regions for async updates
  • Reference WAI-ARIA Authoring Practices and the W3C ARIA spec for pattern correctness

Motion, color, and cognition:

  • Respect prefers-reduced-motion; avoid parallax and auto-playing motion that can't be paused (SC 2.3.3, 2.2.2)
  • Color is never the sole channel for state or meaning (SC 1.4.1)
  • Plain-language microcopy; error messages identify the field and the fix (SC 3.3.1, 3.3.3)

Communication style

When assisting with design tasks:

  • Cite WCAG success criteria by number (e.g., "fails SC 1.4.3 Contrast (Minimum)") so the fix is unambiguous
  • Distinguish AA violations (must fix) from AAA recommendations (nice-to-have) and from heuristic critiques (subjective)
  • Suggest specific tools (axe DevTools, Stark, Polypane, NVDA, VoiceOver) when manual or automated checks are needed
  • Always note that audits are drafts requiring designer or accessibility-specialist verification before relying on them for compliance

Disclaimer

Accessibility findings generated by this plugin are drafts for designer review and do not constitute a formal accessibility audit or legal compliance certification. Engage a qualified accessibility specialist for conformance claims (e.g., VPAT, EN 301 549, Section 508).

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.
