I use the W3 preliminary guidelines - you could try adapting them into a bespoke skill as a good start.

Another possibility (although I’ve never actually tried this myself) is an MCP server that someone built specifically to connect to Lighthouse, which includes accessibility testing as part of its benchmarks.

I am the author of lighthouse-mcp. Plugging in a11y-mcp https://github.com/priyankark/a11y-mcp specifically for a11y and there are a few other variants of it from other authors as well.

I use these tools myself and they just build upon the awesome work from the open source community
