design-accessibility

design-accessibility is a skill for Claude Code from ZachArticulateV/designer-pro-and-seo. It costs 144 tokens per session (1,676 once invoked), scanned A, original, MIT.

An accessibility audit for HTML based on WCAG 2.2, the international guidelines for making websites usable by people with disabilities. It checks page structure and can run a deeper automated scan when Playwright is available.

In plain words
What is it for?
Use it to check image descriptions, headings, form labels, language settings, landmarks, skip links, contrast, keyboard focus, motion, and 200% zoom.
Why use it?
It finds issues that can block screen-reader users, keyboard users, people with low vision, or people using zoom and reduced-motion settings.

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

design-accessibility 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.

design-accessibility

Family: design Status: Stable

Purpose

A dedicated accessibility skill. Runs structural WCAG 2.2 checks on any HTML with no tools required (the free path) and a full axe-core scan when Playwright is installed (the deep path), producing a severity-ranked report that downstream skills (qa-gate, design-build) can act on.

Triggers

  • "accessibility check" / "a11y check" / "wcag audit"
  • "axe scan" / "is this accessible"
  • "screen reader check" / "keyboard nav check"

Inputs

  • Target URL or local build path
  • WCAG level: AA (default) | AAA
  • Viewports to test (defaults: 375 / 768 / 1280)
  • Optional: a design-system token file (from design-system-gen); the token-based contrast check in Step 2 runs only when it is present

Steps

  1. Detect Playwright. If available → deep path (step 3). If not → static path (step 2). Always say which path ran.
  2. Static WCAG checks (free path, on the page source): run scripts/design/a11y_static.py --file <page.html> — a stdlib html.parser structural checker that emits severity-ranked JSON findings for image alt coverage, heading order (no skipped levels / one <h1>), form-control labels, <html lang>, a skip-to-content link, <main>/landmark presence, and a responsive (non-zoom-blocking) viewport meta. When a design-system-gen token file is present, pass --tokens <tokens.json> to add the token-contrast cross-check (the engine's own WCAG luminance math over the text/bg/ surface/primary/on_primary/accent slots). See references/design-accessibility/structural-checks.md for the full check catalog + severity model.
  3. Deep axe scan (Playwright path): for each viewport, run axe-core; test keyboard nav (tab order, visible focus, focus traps in modals, escape routes); test prefers-reduced-motion; test 200% text scaling for truncation/overflow; verify computed-style color contrast.
  4. Classify findings critical / serious / moderate / minor with the WCAG success criterion and remediation guidance (file:line when source is available).
  5. Render the report; note clearly that the static path is a subset and a full axe scan needs Playwright.

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.
