This handles the discovery phase of accessibility audits, whether you're scanning a single page or crawling an entire site. It wraps axe-core CLI for runtime WCAG checks, grabs screenshots with capture-website-cli, and can pull URLs from sitemaps or crawl links up to a configurable page limit. The skill detects your framework from package.json or file extensions to inform code reviews. What I like here is the practical table of when to use runtime scanning versus code review versus both. It's opinionated about defaults like capping crawls at 50 pages and comes with a config file format if you want to lock down your audit parameters across runs.
