name	design-polish
description	Performs a final quality pass fixing alignment, spacing, consistency, and micro-detail issues before shipping. Use when the user mentions polish, finishing touches, pre-launch review, something looks off, or wants to go from good to great.
version	2.1.1
user-invocable	true
argument-hint	[target]

MANDATORY PREPARATION

Read the design guidelines which contain design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if .impeccable.md exists in the project root, read it for design context. If no design context exists yet, tell the user to run /wf-design:setup first.

Perform a meticulous final pass to catch all the small details that separate good work from great work. The difference between shipped and polished.

Design System Discovery

Before polishing, understand the system you are polishing toward:

1. Find the design system: Search for design system documentation, component libraries, style guides, or token definitions. Study the core patterns: color tokens, spacing scale, typography styles, component API.
2. Note the conventions: How are shared components imported? What spacing scale is used? Which colors come from tokens vs hard-coded values? What motion and interaction patterns are established?
3. Identify drift: Where does the target feature deviate from the system? Hard-coded values that should be tokens, custom components that duplicate shared ones, spacing that doesn't match the scale.

If a design system exists, polish should align the feature with it. If none exists, polish against the conventions visible in the codebase.

Pre-Polish Assessment

Understand the current state and goals:

1. 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?)

2. 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 any or 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
• Touch targets are 44x44px minimum
• Contrast ratios meet WCAG AA
• Keyboard navigation works
• Focus indicators visible
• No console errors or warnings
• 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)
• Create new one-off components when design system equivalents exist
• Hard-code values that should use design tokens

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

Clean Up

After polishing, ensure code quality:

• Replace custom implementations: If the design system provides a component you reimplemented, switch to the shared version.
• Remove orphaned code: Delete unused styles, components, or files made obsolete by polish.
• Consolidate tokens: If you introduced new values, check whether they should be tokens.
• Verify DRYness: Look for duplication introduced during polishing and consolidate.

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.
