WCAG Accessibility skill
I built a Claude skill that audits content against WCAG 2.2.
I'm colorblind, so accessibility isn't abstract to me. It's the difference between being able to use something and not. That's what pushed me to build this.
You paste in your HTML, Markdown, a component description, or even just explain how a UI works, and it gives you a pass/fail/partial verdict for every applicable WCAG 2.2 success criterion, plus specific remediation steps to fix what's broken.
A few things I wanted it to do that most tools don't:
- Call out the criteria that are new in WCAG 2.2 (there are 8 of them — things like minimum target size, dragging movement alternatives, and accessible authentication)
- Be honest about what can't be assessed from a snippet alone, rather than quietly skipping it
- Give you a prioritised action plan, not just a list of failures
It covers all four WCAG principles across all 78 success criteria at Level A, AA, and AAA.
