UI Design Review

When to Use

Use this skill when you need review UI code for design system compliance, accessibility, and best practices.

When NOT to use

  • For accessibility-only issues → use /ss-a11y
  • For Nielsen UX heuristics → use /ss-audit
  • For a quick automated check → use /ss-lint
  • For non-UI code (data fetching, business rules)

Checklist

1. Design Token Compliance

  • No hardcoded hex colors (use semantic tokens: text-foreground, bg-brand, etc.)
  • No hardcoded px spacing in Tailwind (use p-6 not p-[24px])
  • Shadows use CSS variables (shadow-[var(--shadow-card)])
  • Border radius follows the scale (rounded-md, rounded-lg, rounded-2xl)

2. Component Conventions

  • Uses data-slot attribute
  • Uses cn() for className merging
  • Props typed with React.ComponentProps<>
  • Supports className prop override
  • Named export (not default export for components)
  • No wrapper components that only add a className

3. Accessibility (a11y)

  • Touch targets >= 44x44px for interactive elements
  • focus-visible styles on all interactive elements
  • Proper aria-* attributes where needed
  • Color contrast meets WCAG AA (4.5:1 for text, 3:1 for large text)
  • Animations respect prefers-reduced-motion
  • Images have alt text
  • Form inputs have associated labels

4. Mobile Best Practices

  • No horizontal overflow
  • Touch-friendly spacing between interactive elements
  • Safe area insets handled for notched devices
  • Text sizes >= 12px for readability
  • Scrollable containers have -webkit-overflow-scrolling: touch

5. Performance

  • No unnecessary re-renders (stable references, memoization where needed)
  • Images are lazy-loaded
  • Heavy components are code-split

6. Typography

  • Uses the Pretendard/Inter font stack
  • Font sizes from the 14-step scale (10-48px, see CLAUDE.md)
  • Proper font weights (400, 500, 600, 700)
  • Display text (36-48px): leading-none + tracking-[-0.02em]
  • Heading text (18-24px): leading-snug + tracking-[-0.01em]
  • Body text (14-17px): leading-normal (no custom tracking)
  • Caption uppercase (10-13px): tracking-[0.05em] or tracking-wide
  • No line-height: 1.5 on display/heading text (too loose)

7. Spacing Consistency

  • All spacing values are multiples of 6px (p-1.5, p-3, p-6, etc.)
  • No arbitrary spacing (p-5=20px, gap-3.5=14px are violations)
  • Uses size-* shorthand instead of w-* h-*
  • Uses ms-*/me-* instead of ml-*/mr-* (logical properties)
  • Motion transitions use design tokens (duration-[var(--duration-fast)])

8. Coherence (VISUAL-CRAFT.md §C0 — the "one choice per axis" laws)

The biggest reason a UI reads as "AI-generated" isn't ugly parts — it's mixed parts. Check that each axis below uses ONE value system-wide; flag a mix as a real issue, not a nitpick.

  • One radius personality — sharp (0-4px) OR soft (8-12px) OR pill, applied to every card/button/input/modal. No mixing (e.g. a rounded-none panel with rounded-full buttons).
  • One accent color for interactive emphasis (+ semantic red/green/amber only) — not two+ competing accents.
  • No emoji as UI icons (🚗🧺⭐ as list/nav/status/category markers) — they inject many uncontrolled hues; use one line-icon set in currentColor.
  • Status color = severity, not decoration — a normal/OK/"보통" state is neutral grey (not colored); color marks only the minority of rows that need attention; same value → same color.
  • No decorative hues — favorite stars, category dots, avatars use the accent or grey, not a new color each.
  • One shadow language — same light direction, same scale/tint; not some black + some tinted, some up-lit + some down-lit.
  • One icon family / fill mode / stroke weight across the file.
  • Nested-radius law — an element inside a rounded container uses inner = outer − padding, not the same radius (which bulges).
  • Consistent control heights — buttons, inputs, selects share a height set (e.g. 40px).
  • Errors/states never rely on color alone (icon + text too).

Output Format

Provide:

  1. Score: Pass / Needs Improvement / Fail
  2. Issues: List each violation with file:line reference
  3. Fixes: Concrete code changes for each issue

Limitations

  • Use this skill only when the task clearly matches its upstream source and local project context.
  • Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
  • Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
