Claude Code WCAG Accessibility Audit (2026)

Web accessibility ensures that people with disabilities can perceive, understand, navigate, and interact with your digital products. This guide shows you how to use Claude Code skills, /frontend-design, /tdd, /pdf, and /supermemory, to build a complete accessibility audit workflow: from component generation through automated CI/CD checks to formal stakeholder reports.

If you need to review existing code snippet-by-snippet for specific WCAG 2.1 violations (contrast ratios, ARIA state, keyboard traps), see the Claude Code WCAG 2.1 Compliance Checker Workflow Guide instead. This guide focuses on the skills layer, orchestrating Claude’s built-in capabilities to audit at project scale.

Setting Up Your Accessibility Skills

Claude Code supports accessibility-focused skills that guide the auditing process. The primary skill you’ll use is /frontend-design, which includes accessibility considerations in component generation. For comprehensive audits, pair this with the /tdd skill to create test cases for accessibility requirements.

Your skill setup directory should include:

~/.claude/skills/
 frontend-design.md
 tdd.md
 pdf.md

Each skill is a Markdown file that Claude loads when you invoke its slash command. The /frontend-design skill ensures new components follow WCAG patterns from the start, while /tdd helps you write tests that verify accessibility behavior.

Mapping Skills to Audit Phases

A skills-based audit workflow covers three distinct phases, each handled by a different Claude skill:

Phase 1. Prevent (during development) Use /frontend-design when building new components. The skill bakes WCAG patterns in from the start: semantic landmarks, proper heading hierarchy, label associations, and focus management. Prevention is cheaper than remediation.

Phase 2. Detect (during testing) Use /tdd to generate accessibility-specific test cases. These become your regression safety net, catching issues before they reach production. Pair with axe-core for automated runtime analysis.

Phase 3. Report (after audit) Use /pdf to generate formal audit documentation for stakeholders and compliance records. Use /supermemory to persist your organization’s accessibility patterns across sessions so Claude remembers project-specific conventions.

This three-phase structure is what separates a skills-based workflow from one-off code review. Each skill handles a discrete responsibility, and together they cover the full audit lifecycle.

Automated Testing with Axe and Claude

Integrate automated accessibility testing into your development workflow. Install axe-core for runtime analysis:

npm install --save-dev @axe-core/cli

Create a test file that Claude can help you write using the /tdd skill:

// tests/accessibility/homepage.a11y.test.js
import { chromium } from 'playwright';
import axe from 'axe-core';
describe('Homepage Accessibility', () => {
 it('should pass axe-core accessibility checks', async () => {
 const browser = await chromium.launch();
 const page = await browser.newPage();
 
 await page.goto('http://localhost:3000');
 
 const results = await page.evaluate(() => {
 return axe.run();
 });
 
 // Fail if there are critical violations
 const criticalViolations = results.violations.filter(
 v => v.impact === 'critical'
 );
 
 expect(criticalViolations).toHaveLength(0);
 
 await browser.close();
 });
});

When you need to expand your test coverage, invoke the /tdd skill in Claude Code and describe the component you want tested. Claude will generate test cases that verify accessibility behavior.

Manual Audit Workflow with Claude

Automated testing catches only about 30-40% of accessibility issues. For the remainder, use Claude to guide your manual audit. Here’s a practical workflow:

Step 1: Generate audit script Tell Claude what you’re auditing:

/frontend-design
Review this React component for WCAG 2.1 Level AA compliance. Check for:
- Missing alt text on images
- Improper heading hierarchy (h1-h6 sequence)
- Missing form labels
- Insufficient color contrast
- Keyboard trap issues

Step 2: Document findings Create an accessibility report structure:

Accessibility Audit Report - [Page Name]
Critical Issues
| Issue | WCAG Criterion | Location | Remediation |
|-------|---------------|----------|-------------|
| Missing alt on logo | 1.1.1 | header.jsx:15 | Add alt="Company Name" |
Moderate Issues
| Issue | WCAG Criterion | Location |
|-------|---------------|----------|
| Low contrast button | 1.4.3 | cta.jsx:42 |
Recommendations
- Add skip navigation link
- Implement focus indicators

Step 3: Prioritize remediation Focus on fixing critical issues first, the ones that prevent users from accessing content entirely. Moderate issues affect the experience but don’t block access entirely.

Using the PDF Skill for Reports

After completing your audit, generate a formal report using the /pdf skill. This is useful for documentation, stakeholder sharing, or compliance records:

Accessibility Audit Report
[Project Name]
Date: [Audit Date]
Auditor: [Name]
Executive Summary
[Summary of findings]
Critical Violations
[List with WCAG references]
Remediation Plan
[Priority-ordered fixes]

Invoke /pdf in Claude Code and provide your audit data. Claude will format it into a professional PDF document.

Integrating Accessibility into CI/CD

Automate accessibility checks in your continuous integration pipeline:

.github/workflows/accessibility.yml
name: Accessibility Checks
on: [push, pull_request]
jobs:
 a11y-test:
 runs-on: ubuntu-latest
 steps:
 - uses: actions/checkout@v4
 
 - name: Set up Node
 uses: actions/setup-node@v4
 with:
 node-version: '20'
 
 - name: Install dependencies
 run: npm ci
 
 - name: Build application
 run: npm run build
 
 - name: Run accessibility tests
 run: npm test -- --testPathPattern=a11y
 
 - name: Upload accessibility report
 uses: actions/upload-artifact@v4
 with:
 name: a11y-report
 path: reports/accessibility/

This workflow runs your accessibility tests on every push and pull request, catching regressions before they reach production.

Combining Skills for Comprehensive Audits

The real power comes from combining multiple Claude skills:

  • Use /frontend-design when building new components, they’ll be accessible by default
  • Use /tdd to create regression tests for accessibility fixes
  • Use /supermemory to store your organization’s accessibility patterns so Claude remembers them across sessions
  • Use /pdf to generate formal audit reports for stakeholders

Each skill operates independently but works well together. You can invoke multiple skills in a single Claude Code session.

Common Accessibility Issues and Fixes

Here are frequent issues Claude helps identify and fix:

Missing form labels

// Before (inaccessible)
<input type="email" placeholder="Email">
// After (accessible)
<label for="email">Email address</label>
<input type="email" id="email" placeholder="[email protected]">

Improper heading hierarchy

// Before (confusing structure)
<h1>Welcome</h1>
<h3>About us</h3>
// After (logical structure)
<h1>Welcome</h1>
<h2>About us</h2>

Poor color contrast

/* Before (fails WCAG) */
.button-primary {
 background-color: #999;
 color: #fff;
}
/* After (passes WCAG AA) */
.button-primary {
 background-color: #0056b3;
 color: #fff;
}

CLAUDE.md for Accessibility Standards

Define your accessibility standards in a CLAUDE.md file so Claude Code enforces them automatically when working on components:

Accessibility Requirements
All components must pass WCAG 2.1 AA standards. Before writing any component:

1. Use semantic HTML elements (header, nav, main, footer)
2. Include proper ARIA labels where semantic elements aren't sufficient
3. Ensure keyboard navigation works for all interactive elements
4. Verify color contrast meets 4.5:1 for normal text
5. Add alt text to all meaningful images
After implementing, run: npx playwright test --grep "accessibility"

For full automation, add Playwright with axe-core to your CI pipeline. This catches regressions on every push and pull request, blocking merges when critical issues are found.

Conclusion

Building a WCAG accessibility audit workflow with Claude Code skills means shifting from reactive code review to a systematic practice. The /frontend-design skill prevents violations at the component level. The /tdd skill encodes accessibility requirements as executable tests. The CI/CD pipeline catches regressions automatically. The /pdf skill turns audit findings into formal documentation, and /supermemory preserves your team’s accumulated patterns across sessions.

This is project-scale accessibility work. For hands-on analysis of specific code, checking a single component’s contrast ratios, dissecting ARIA state, or tracing keyboard focus through a modal, the Claude Code WCAG 2.1 Compliance Checker Workflow Guide covers that layer in detail.
