Web Design Guidelines (Vercel)
Overview
Use this skill to audit UI code against Vercel’s Web Interface Guidelines. Focus on accessibility, focus states, forms, performance, and interaction rules.
When to Use
- •Reviewing UI for accessibility or UX issues
- •Auditing new components for best practices
- •Checking forms, dialogs, focus, or navigation behavior
- •Verifying design consistency and interaction rules
How It Works
- •Fetch the latest rules from:
https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md - •Read the specified files or ask which files to review
- •Compare code against the rules
- •Report findings using the output format in the guidelines
Quick Reference
- •Accessibility: aria-labels, semantic HTML, keyboard handlers
- •Focus: visible focus, focus-visible, trap in dialogs
- •Forms: labels, validation, error messaging
- •Navigation: URL state, deep-linking, internal links
- •Performance: image sizing, lazy loading, layout stability
Example Trigger
"Review this modal for accessibility and focus handling." → Use this skill to fetch guidelines and audit the modal component.
Common Mistakes
- •Skipping the guideline fetch and relying on memory
- •Reviewing without the file list or pattern
- •Ignoring the required output format
