Design Review
Run a comprehensive design review on the specified file or component using principles from Emil Kowalski's design engineering philosophy and jakubkrehel's interface polish guidelines.
Review Process
- Read the target file(s) the user specifies
- Audit against these checklists (only flag actual issues found, not theoretical concerns):
Typography
- [ ] Font smoothing applied at root (
-webkit-font-smoothing: antialiased) - [ ] Headings use
text-wrap: balance - [ ] Body text uses
text-wrap: pretty - [ ] Dynamic numbers use
font-variant-numeric: tabular-nums
Surfaces
- [ ] Nested rounded elements use concentric border radius (
outer = inner + padding) - [ ] Icons are optically centered
- [ ] Shadows used instead of borders for depth (borders OK for dividers)
- [ ] Images have subtle outlines
- [ ] Interactive elements have 40x40px minimum hit area
Animations
- [ ] No
transition: all— specific properties only - [ ] Enter animations are split and staggered
- [ ] Exit animations are subtle (small translateY, not dramatic)
- [ ] No
scale(0)— start fromscale(0.95)withopacity: 0 - [ ] Correct easing:
ease-outfor enters,ease-in-outfor movement - [ ] UI animations under 300ms
- [ ] Custom easing curves, not browser defaults
- [ ]
prefers-reduced-motionrespected - [ ] Hover states gated behind
@media (hover: hover) - [ ] Buttons have
:activescale feedback (scale(0.96)) - [ ] Popovers are origin-aware (not modals — those stay centered)
Performance
- [ ] Only animating
transform,opacity,filter - [ ]
will-changeused sparingly and only for GPU-compositable properties - [ ] CSS transitions for interactive elements (not keyframes)
Distinctiveness (anti-AI-slop, from frontend-design)
- [ ] No generic system fonts (Inter, Roboto, Arial, system-ui) unless intentional and justified
- [ ] No purple-on-white gradient backgrounds or other cliched AI palettes
- [ ] No predictable centered hero + 3-column feature grid unless the design genuinely calls for it
- [ ] One bold aesthetic decision the viewer will remember (typography, color, motion, or layout)
- [ ] Background has atmosphere (gradient mesh, noise, texture, layered transparency) — not a flat fill by default
- [ ] Implementation complexity matches the aesthetic ambition (maximalist needs effects; minimalist needs precision)
Accessibility (SSR-specific)
- [ ] Semantic HTML structure
- [ ] ARIA labels where needed
- [ ] Keyboard navigable
- [ ] Screen reader friendly content order
- [ ] Sufficient color contrast
- [ ] Focus indicators visible
Output Format
Use a markdown table for all findings:
| Issue | Location | Before | After | Why |
|---|---|---|---|---|
| ... | line:col | current code | suggested code | reasoning |
End with a summary: X issues found, Y quick fixes, Z architectural.
