This one gives Claude expertise in WCAG 2.1/2.2 compliance testing and accessibility auditing. It covers the practical stuff you'd actually need: screen reader testing with VoiceOver, NVDA, and JAWS, keyboard navigation checks, automated testing integration with Axe and Pa11y in your CI/CD pipeline, and semantic HTML/ARIA validation. It also handles color contrast checks and can help you build VPATs if you're dealing with enterprise or government contracts. With 139 installs and passing security audits, it seems like a solid choice if you need to ensure your product is usable by people with disabilities without having to memorize WCAG guidelines yourself.
