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.
