Overview

This skill is a WCAG 2.2 AA compliance expert focused on audits, automated testing, screen reader validation, and remediation guidance. It helps teams identify, prioritize, and fix accessibility barriers across web and mobile products. The skill delivers actionable reports, remediation scripts, and compliance documentation to support legal and usability goals.

How this skill works

I combine automated scanning (Axe, Pa11y, Lighthouse) with manual techniques: keyboard audits, screen reader checks (NVDA, VoiceOver, JAWS, TalkBack), and mobile touch/gesture validation. Results are triaged using a remediation prioritization matrix that maps impact and effort to clear fix priorities. I can generate VPATs, integrate tests into CI/CD, and provide code-level fixes and re-test validation.

When to use it

• Before launch to validate WCAG 2.1/2.2 AA compliance
• When adding components or a design system to ensure accessible primitives
• To integrate accessibility checks into CI/CD and prevent regressions
• When diagnosing keyboard, focus, or screen reader issues in production flows
• For mobile apps to verify touch target size, gestures, and dynamic type support

Best practices

• Automate early and run manual audits regularly; automated tools catch ~30–50% of issues
• Prefer semantic HTML and native controls over ARIA shims
• Prioritize fixes by impact (keyboard access, missing labels, contrast) before cosmetic adjustments
• Include people with disabilities in usability testing when possible
• Document evidence, track accessibility debt, and update VPATs when changes occur

Example use cases

• E-commerce launch: full automated + manual audit across product listing and checkout, plus remediation plan for missing alt text and focus traps
• Component library: unit tests with jest-axe, visual focus-state review, and screen reader expectations for each widget
• CI/CD pipeline: run Axe/Pa11y on critical paths, fail builds for high-severity violations, and auto-file issues for tracking
• Mobile app: touch target size audit, gesture alternatives review, and dynamic type scaling verification
