Specifically about accessible websites: I’m a web developer. At the request of a designer I work with, I spent a couple hours making a Claude skill that would run through WCAG AA and AAA, check contrast, screen reader experience etc. Since then, we’ve caught many little issues and a few big ones like adding a parallel screen reading element for a visually-oriented search tool. Building and testing the skill gave me better insight into WCAG, too.

I auto-run the skill when certain changes are detected in a branch and it takes just a few minutes. Recommended if your work shows up in browsers.
