ss-a11y Accessibility Audit

Statically audits a component or page against WCAG 2.2 AA and applies the fixes it safely can.

Design & UIIntermediate★ 962⑂ 89AI score 7/10Last updated: Sep 18, 2026

What it does

  • Reads the target component/page file and checks it against WCAG 2.2 AA.
  • Walks the four principles: Perceivable (color contrast, alt text, aria-labels), Operable (44x44 touch targets, keyboard/tab order, focus-visible rings, prefers-reduced-motion), Understandable (visible labels, aria-describedby error wiring, lang), Robust (semantic HTML, ARIA via Radix, custom roles).
  • Includes a design-token contrast table (--foreground, --muted-foreground, --brand, --destructive, --success, --warning) with minimum ratios to verify per skin.
  • Reports issues by severity (Critical/Major/Minor), auto-fixes what it can, and flags items needing human judgement.

Who it's for

  • Teams on a StyleSeed project (.styleseed registry, data-slot, semantic tokens).
  • Frontend developers building UI with Tailwind CSS + Radix UI.
  • Design-system owners doing a pre-release accessibility sweep.

Examples

  1. Point it at Button.tsx to catch icon buttons missing aria-label and undersized hit areas.
  2. Audit a form page to verify visible labels and programmatically associated error messages.
  3. Scan an animation-heavy landing page and add the prefers-reduced-motion CSS guard.

Note: this is a static code audit, not a screen-reader simulation. Use /ss-review for design-system compliance and /ss-audit for Nielsen UX heuristics.

Install the skill I found on Claude Skill Mart.
Copy the engine/.claude/skills/ss-a11y folder from the GitHub repo bitjaru/styleseed into my ~/.claude/skills/ss-a11y/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/bitjaru/styleseed.git /tmp/styleseed && mkdir -p ~/.claude/skills && cp -r /tmp/styleseed/engine/.claude/skills/ss-a11y ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal in your working directory.
  2. Clone the repo: git clone https://github.com/bitjaru/styleseed.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r styleseed/engine/.claude/skills/ss-a11y ~/.claude/skills/
  5. Restart Claude Code and run it with a file path, e.g. /ss-a11y src/components/Button.tsx.
  6. If you are not on a StyleSeed project, ignore the .styleseed registry steps and use it as a pure WCAG checklist.
