Web Design Guidelines

This pulls Vercel's Web Interface Guidelines from their GitHub repo and audits your code against them. You trigger it by asking Claude to review UI, check accessibility, or audit design. It fetches the latest rules each time so you're always checking against current standards, then outputs findings in a terse file:line format that's easy to scan. The guidelines themselves live in a separate repo, so you're basically getting Vercel's opinionated take on web best practices baked into your code reviews. Saves you from having to remember accessibility rules or manually cross-checking design patterns when you're deep in implementation.
