Accessibility Audit

Automated WCAG 2.2 accessibility audit: axe-core scanning, keyboard navigation testing, color contrast verification, ARIA compliance, and assistive technology error analysis. Works with any project — auto-detects pages from the codebase route structure.

Critical Rules

Always use the browser-anti-stall protocol when using Playwright browser MCP tools.

Test every publicly reachable page. Accessibility bugs on obscure pages still affect real users.

Keyboard-only testing is non-negotiable. If a feature cannot be operated without a mouse, it fails WCAG 2.1.1 regardless of what axe-core says.

Automated tools catch ~30-40% of a11y issues. Always supplement axe-core with manual checks (heading order, focus management, meaningful link text, reading order).

Use concrete WCAG success criteria IDs. "Color contrast is bad" is not actionable. "Fails WCAG 2.2 SC 1.4.3 (Contrast Minimum) — foreground #777 on background #fff = 4.48:1, needs 4.5:1" is.
