UI Design Review

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

Read .styleseed/effective-rules.md and .styleseed/manifest.json. If missing or stale, invoke /ss-resolve or $ss-resolve from STYLESEED.md first. Review task fitness and grammar coherence before framework conventions. For non-web artifacts, replace React/Tailwind-only checks with the active adapter's render/export checks.

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 and Recipe 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])
• Pattern geometry/elevation uses the selected recipe or explicit semantic variables
• No hardcoded universal rounded-2xl + shadow + mx-6 language across unrelated recipes

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. Surface Best Practices

• No horizontal overflow
• Touch-friendly spacing between interactive elements
• Mobile safe area insets handled when the adapter requires them
• Desktop density/type and non-web canvas/export rules follow the selected adapter
• 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 locked type family and recipe-fit type roles
• 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

• Spacing uses one maintained token scale and the selected recipe's major rhythm
• Off-scale values have an optical, canvas, or platform reason
• 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 identifiable primary action plus only the selected grammar's stable semantic,

categorical, or brand roles — no competing decorative emphasis hues.

• 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).
