Web Design Guidelines
vercel-labs/agent-skillsOfficial
A solid UI audit tool that pulls the latest Web Interface Guidelines from Vercel's GitHub repo and checks your code against them. Point it at your HTML, CSS, or component files and it'll flag accessibility issues, design inconsistencies, and UX problems in a clean file:line format. The guidelines stay current since it fetches fresh rules on each run rather than using stale built-in checks. Handy for catching common web standards violations before they ship, especially if you're working fast and might miss obvious accessibility or usability issues.
