This pulls Vercel's Web Interface Guidelines directly from their repo and runs your UI code against them automatically. It checks React, Vue, Svelte, HTML, CSS, and TypeScript files, spitting out violations in file:line format with specific fixes. The smart bit is that it fetches the latest guidelines before each review, so you're never auditing against stale rules. Useful when you're trying to keep a design system consistent or need to check accessibility and UX patterns before shipping. It handles glob patterns, so you can point it at specific components or sweep entire directories. Basically a linter for design decisions, which is harder to automate than it sounds.
