AfterWhen to use it
/polish is the last thing you run before shipping. It hunts down the small details that separate a shipped feature from a polished one: half-pixel misalignments, inconsistent spacing, forgotten focus states, loading transitions that flash, copy that drifts in tone.
Reach for it when the feature is functionally complete, nothing is broken, and something still feels off.
How it works
Polish works methodically across six dimensions:
- Visual alignment and spacing: pixel-perfect grid adherence, consistent spacing scale, optical alignment on icons.
- Typography: hierarchy consistency, line length, widows and orphans, kerning on headlines.
- Color and contrast: token usage, theme parity, WCAG ratios, focus indicators.
- Interaction states: hover, focus, active, disabled, loading, error, success. Every state accounted for.
- Transitions and motion: smooth easing, no layout jank, respect for
prefers-reduced-motion. - Copy: consistent voice, correct tense, no placeholder strings, no stray TODOs.
The skill is explicit about one thing: polish is the last step, not the first. If the feature is not functionally complete, polishing it is wasted work.
Try it
/polish the pricing pageA healthy run looks like:
Visual alignment: fixed 3 off-grid elements (8px baseline)
Typography: tightened h1 kerning, fixed widow on testimonial
Interaction: added hover state on FAQ items, focus ring on email input
Motion: softened modal entrance, added reduced-motion fallback
Copy: removed one "Lorem ipsum" stray, aligned button voiceFive small fixes, no rewrites. That is the shape of a good polish pass.
Pitfalls
- Polishing work that is not done. If there are TODOs in the code, you are not ready. Run
/polishon finished features only. - Treating polish as redesign. Polish refines what exists. If you find yourself rearchitecting a layout, you needed
/critiqueor/arrangeinstead. - Running
/polishwithout/auditfirst. Polish catches feel-based issues. Audit catches measurable ones. Use both.
MANDATORY PREPARATION
Invoke {{command_prefix}}impeccable — it contains design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no design context exists yet, you MUST run {{command_prefix}}impeccable teach first. Additionally gather: quality bar (MVP vs flagship).
Perform a meticulous final pass to catch all the small details that separate good work from great work. The difference between shipped and polished.
Pre-Polish Assessment
Understand the current state and goals:
Review completeness:
- Is it functionally complete?
- Are there known issues to preserve (mark with TODOs)?
- What's the quality bar? (MVP vs flagship feature?)
- When does it ship? (How much time for polish?)
Identify polish areas:
- Visual inconsistencies
- Spacing and alignment issues
- Interaction state gaps
- Copy inconsistencies
- Edge cases and error states
- Loading and transition smoothness
CRITICAL: Polish is the last step, not the first. Don't polish work that's not functionally complete.
Polish Systematically
Work through these dimensions methodically:
Visual Alignment & Spacing
- Pixel-perfect alignment: Everything lines up to grid
- Consistent spacing: All gaps use spacing scale (no random 13px gaps)
- Optical alignment: Adjust for visual weight (icons may need offset for optical centering)
- Responsive consistency: Spacing and alignment work at all breakpoints
- Grid adherence: Elements snap to baseline grid
Check:
- Enable grid overlay and verify alignment
- Check spacing with browser inspector
- Test at multiple viewport sizes
- Look for elements that "feel" off
Typography Refinement
- Hierarchy consistency: Same elements use same sizes/weights throughout
- Line length: 45-75 characters for body text
- Line height: Appropriate for font size and context
- Widows & orphans: No single words on last line
- Hyphenation: Appropriate for language and column width
- Kerning: Adjust letter spacing where needed (especially headlines)
- Font loading: No FOUT/FOIT flashes
Color & Contrast
- Contrast ratios: All text meets WCAG standards
- Consistent token usage: No hard-coded colors, all use design tokens
- Theme consistency: Works in all theme variants
- Color meaning: Same colors mean same things throughout
- Accessible focus: Focus indicators visible with sufficient contrast
- Tinted neutrals: No pure gray or pure black—add subtle color tint (0.01 chroma)
- Gray on color: Never put gray text on colored backgrounds—use a shade of that color or transparency
Interaction States
Every interactive element needs all states:
- Default: Resting state
- Hover: Subtle feedback (color, scale, shadow)
- Focus: Keyboard focus indicator (never remove without replacement)
- Active: Click/tap feedback
- Disabled: Clearly non-interactive
- Loading: Async action feedback
- Error: Validation or error state
- Success: Successful completion
Missing states create confusion and broken experiences.
Micro-interactions & Transitions
- Smooth transitions: All state changes animated appropriately (150-300ms)
- Consistent easing: Use ease-out-quart/quint/expo for natural deceleration. Never bounce or elastic—they feel dated.
- No jank: 60fps animations, only animate transform and opacity
- Appropriate motion: Motion serves purpose, not decoration
- Reduced motion: Respects
prefers-reduced-motion
Content & Copy
- Consistent terminology: Same things called same names throughout
- Consistent capitalization: Title Case vs Sentence case applied consistently
- Grammar & spelling: No typos
- Appropriate length: Not too wordy, not too terse
- Punctuation consistency: Periods on sentences, not on labels (unless all labels have them)
Icons & Images
- Consistent style: All icons from same family or matching style
- Appropriate sizing: Icons sized consistently for context
- Proper alignment: Icons align with adjacent text optically
- Alt text: All images have descriptive alt text
- Loading states: Images don't cause layout shift, proper aspect ratios
- Retina support: 2x assets for high-DPI screens
Forms & Inputs
- Label consistency: All inputs properly labeled
- Required indicators: Clear and consistent
- Error messages: Helpful and consistent
- Tab order: Logical keyboard navigation
- Auto-focus: Appropriate (don't overuse)
- Validation timing: Consistent (on blur vs on submit)
Edge Cases & Error States
- Loading states: All async actions have loading feedback
- Empty states: Helpful empty states, not just blank space
- Error states: Clear error messages with recovery paths
- Success states: Confirmation of successful actions
- Long content: Handles very long names, descriptions, etc.
- No content: Handles missing data gracefully
- Offline: Appropriate offline handling (if applicable)
Responsiveness
- All breakpoints: Test mobile, tablet, desktop
- Touch targets: 44x44px minimum on touch devices
- Readable text: No text smaller than 14px on mobile
- No horizontal scroll: Content fits viewport
- Appropriate reflow: Content adapts logically
Performance
- Fast initial load: Optimize critical path
- No layout shift: Elements don't jump after load (CLS)
- Smooth interactions: No lag or jank
- Optimized images: Appropriate formats and sizes
- Lazy loading: Off-screen content loads lazily
Code Quality
- Remove console logs: No debug logging in production
- Remove commented code: Clean up dead code
- Remove unused imports: Clean up unused dependencies
- Consistent naming: Variables and functions follow conventions
- Type safety: No TypeScript
anyor ignored errors - Accessibility: Proper ARIA labels and semantic HTML
Polish Checklist
Go through systematically:
- Visual alignment perfect at all breakpoints
- Spacing uses design tokens consistently
- Typography hierarchy consistent
- All interactive states implemented
- All transitions smooth (60fps)
- Copy is consistent and polished
- Icons are consistent and properly sized
- All forms properly labeled and validated
- Error states are helpful
- Loading states are clear
- Empty states are welcoming

- No layout shift on load
- Works in all supported browsers
- Respects reduced motion preference
- Code is clean (no TODOs, console.logs, commented code)
IMPORTANT: Polish is about details. Zoom in. Squint at it. Use it yourself. The little things add up.
NEVER:
- Polish before it's functionally complete
- Spend hours on polish if it ships in 30 minutes (triage)
- Introduce bugs while polishing (test thoroughly)
- Ignore systematic issues (if spacing is off everywhere, fix the system)
- Perfect one thing while leaving others rough (consistent quality level)
Final Verification
Before marking as done:
- Use it yourself: Actually interact with the feature
- Test on real devices: Not just browser DevTools
- Ask someone else to review: Fresh eyes catch things
- Compare to design: Match intended design
- Check all states: Don't just test happy path
Remember: You have impeccable attention to detail and exquisite taste. Polish until it feels effortless, looks intentional, and works flawlessly. Sweat the details - they matter.
