Accessibility Auditor

Audits a website for accessibility defects and guides fixes up to WCAG 2.1 AA compliance.

Design & UIIntermediate★ 251⑂ 40AI score 7/10Last updated: Aug 11, 2026

What it does

Gives Claude a five-step audit workflow for reaching WCAG 2.1 AA:

  1. Automated checks — run axe-style CLI scans, add jest-axe or Playwright a11y assertions
  2. Keyboard testing — tab order, activation, Escape behavior, visible focus, no focus traps
  3. Screen reader testing — walk the page with NVDA or VoiceOver and verify name, role, announced state
  4. WCAG criteria review — go through each Level A and AA criterion on the checklist
  5. Apply fixes — use the seven most common fix patterns plus ARIA patterns for tabs, accordion, menu, alert, and progress, then re-scan for zero violations

It relies on four bundled references/ documents.

Who it's for

  • Front-end developers, web publishers, UI engineers
  • Teams with legal accessibility obligations (government, finance, education)
  • Teams wiring a11y checks into CI
  • Design system maintainers auditing component ARIA

Examples

  • "Audit our landing page for accessibility" → Claude runs the steps in order and reports violations
  • "Make this custom tab component screen-reader friendly" → fixes roles, aria-selected, and focus management per the ARIA patterns
  • "Add a11y assertions to our Playwright suite" → inserts checks and iterates until zero violations

Let Claude do it — paste this into Claude Code

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

Install with a command instead

git clone https://github.com/OneWave-AI/claude-skills.git && mkdir -p ~/.claude/skills && cp -r claude-skills/accessibility-auditor ~/.claude/skills/

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

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/OneWave-AI/claude-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the whole skill folder so the reference docs come along: cp -r claude-skills/accessibility-auditor ~/.claude/skills/
  5. Verify with ls ~/.claude/skills/accessibility-auditor/references — you should see four .md files.
  6. Restart Claude Code and ask something like "audit this site for accessibility issues."
  7. Optional: install Node.js plus @axe-core/cli and Playwright so the automated scan step can actually run.
