+
+Adapt existing designs to work effectively across different contexts - different screen sizes, devices, platforms, or use cases.
+
+## MANDATORY PREPARATION
+
+Invoke /frontend-design — 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 /teach-impeccable first. Additionally gather: target platforms/devices and usage contexts.
+
+---
+
+## Assess Adaptation Challenge
+
+Understand what needs adaptation and why:
+
+1. **Identify the source context**:
+   - What was it designed for originally? (Desktop web? Mobile app?)
+   - What assumptions were made? (Large screen? Mouse input? Fast connection?)
+   - What works well in current context?
+
+2. **Understand target context**:
+   - **Device**: Mobile, tablet, desktop, TV, watch, print?
+   - **Input method**: Touch, mouse, keyboard, voice, gamepad?
+   - **Screen constraints**: Size, resolution, orientation?
+   - **Connection**: Fast wifi, slow 3G, offline?
+   - **Usage context**: On-the-go vs desk, quick glance vs focused reading?
+   - **User expectations**: What do users expect on this platform?
+
+3. **Identify adaptation challenges**:
+   - What won't fit? (Content, navigation, features)
+   - What won't work? (Hover states on touch, tiny touch targets)
+   - What's inappropriate? (Desktop patterns on mobile, mobile patterns on desktop)
+
+**CRITICAL**: Adaptation is not just scaling - it's rethinking the experience for the new context.
+
+## Plan Adaptation Strategy
+
+Create context-appropriate strategy:
+
+### Mobile Adaptation (Desktop → Mobile)
+
+**Layout Strategy**:
+- Single column instead of multi-column
+- Vertical stacking instead of side-by-side
+- Full-width components instead of fixed widths
+- Bottom navigation instead of top/side navigation
+
+**Interaction Strategy**:
+- Touch targets 44x44px minimum (not hover-dependent)
+- Swipe gestures where appropriate (lists, carousels)
+- Bottom sheets instead of dropdowns
+- Thumbs-first design (controls within thumb reach)
+- Larger tap areas with more spacing
+
+**Content Strategy**:
+- Progressive disclosure (don't show everything at once)
+- Prioritize primary content (secondary content in tabs/accordions)
+- Shorter text (more concise)
+- Larger text (16px minimum)
+
+**Navigation Strategy**:
+- Hamburger menu or bottom navigation
+- Reduce navigation complexity
+- Sticky headers for context
+- Back button in navigation flow
+
+### Tablet Adaptation (Hybrid Approach)
+
+**Layout Strategy**:
+- Two-column layouts (not single or three-column)
+- Side panels for secondary content
+- Master-detail views (list + detail)
+- Adaptive based on orientation (portrait vs landscape)
+
+**Interaction Strategy**:
+- Support both touch and pointer
+- Touch targets 44x44px but allow denser layouts than phone
+- Side navigation drawers
+- Multi-column forms where appropriate
+
+### Desktop Adaptation (Mobile → Desktop)
+
+**Layout Strategy**:
+- Multi-column layouts (use horizontal space)
+- Side navigation always visible
+- Multiple information panels simultaneously
+- Fixed widths with max-width constraints (don't stretch to 4K)
+
+**Interaction Strategy**:
+- Hover states for additional information
+- Keyboard shortcuts
+- Right-click context menus
+- Drag and drop where helpful
+- Multi-select with Shift/Cmd
+
+**Content Strategy**:
+- Show more information upfront (less progressive disclosure)
+- Data tables with many columns
+- Richer visualizations
+- More detailed descriptions
+
+### Print Adaptation (Screen → Print)
+
+**Layout Strategy**:
+- Page breaks at logical points
+- Remove navigation, footer, interactive elements
+- Black and white (or limited color)
+- Proper margins for binding
+
+**Content Strategy**:
+- Expand shortened content (show full URLs, hidden sections)
+- Add page numbers, headers, footers
+- Include metadata (print date, page title)
+- Convert charts to print-friendly versions
+
+### Email Adaptation (Web → Email)
+
+**Layout Strategy**:
+- Narrow width (600px max)
+- Single column only
+- Inline CSS (no external stylesheets)
+- Table-based layouts (for email client compatibility)
+
+**Interaction Strategy**:
+- Large, obvious CTAs (buttons not text links)
+- No hover states (not reliable)
+- Deep links to web app for complex interactions
+
+## Implement Adaptations
+
+Apply changes systematically:
+
+### Responsive Breakpoints
+
+Choose appropriate breakpoints:
+- Mobile: 320px-767px
+- Tablet: 768px-1023px
+- Desktop: 1024px+
+- Or content-driven breakpoints (where design breaks)
+
+### Layout Adaptation Techniques
+
+- **CSS Grid/Flexbox**: Reflow layouts automatically
+- **Container Queries**: Adapt based on container, not viewport
+- **`clamp()`**: Fluid sizing between min and max
+- **Media queries**: Different styles for different contexts
+- **Display properties**: Show/hide elements per context
+
+### Touch Adaptation
+
+- Increase touch target sizes (44x44px minimum)
+- Add more spacing between interactive elements
+- Remove hover-dependent interactions
+- Add touch feedback (ripples, highlights)
+- Consider thumb zones (easier to reach bottom than top)
+
+### Content Adaptation
+
+- Use `display: none` sparingly (still downloads)
+- Progressive enhancement (core content first, enhancements on larger screens)
+- Lazy loading for off-screen content
+- Responsive images (`srcset`, `picture` element)
+
+### Navigation Adaptation
+
+- Transform complex nav to hamburger/drawer on mobile
+- Bottom nav bar for mobile apps
+- Persistent side navigation on desktop
+- Breadcrumbs on smaller screens for context
+
+**IMPORTANT**: Test on real devices, not just browser DevTools. Device emulation is helpful but not perfect.
+
+**NEVER**:
+- Hide core functionality on mobile (if it matters, make it work)
+- Assume desktop = powerful device (consider accessibility, older machines)
+- Use different information architecture across contexts (confusing)
+- Break user expectations for platform (mobile users expect mobile patterns)
+- Forget landscape orientation on mobile/tablet
+- Use generic breakpoints blindly (use content-driven breakpoints)
+- Ignore touch on desktop (many desktop devices have touch)
+
+## Verify Adaptations
+
+Test thoroughly across contexts:
+
+- **Real devices**: Test on actual phones, tablets, desktops
+- **Different orientations**: Portrait and landscape
+- **Different browsers**: Safari, Chrome, Firefox, Edge
+- **Different OS**: iOS, Android, Windows, macOS
+- **Different input methods**: Touch, mouse, keyboard
+- **Edge cases**: Very small screens (320px), very large screens (4K)
+- **Slow connections**: Test on throttled network
+
+Remember: You're a cross-platform design expert. Make experiences that feel native to each context while maintaining brand and functionality consistency. Adapt intentionally, test thoroughly.

+name: animate
+description: Review a feature and enhance it with purposeful animations, micro-interactions, and motion effects that improve usability and delight. Use when the user mentions adding animation, transitions, micro-interactions, motion design, hover effects, or making the UI feel more alive.
+user-invocable: true
+argument-hint: "[target]"
+---
+
+Analyze a feature and strategically add animations and micro-interactions that enhance understanding, provide feedback, and create delight.
+
+## MANDATORY PREPARATION
+
+Invoke /frontend-design — 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 /teach-impeccable first. Additionally gather: performance constraints.
+
+---
+
+## Assess Animation Opportunities
+
+Analyze where motion would improve the experience:
+
+1. **Identify static areas**:
+   - **Missing feedback**: Actions without visual acknowledgment (button clicks, form submission, etc.)
+   - **Jarring transitions**: Instant state changes that feel abrupt (show/hide, page loads, route changes)
+   - **Unclear relationships**: Spatial or hierarchical relationships that aren't obvious
+   - **Lack of delight**: Functional but joyless interactions
+   - **Missed guidance**: Opportunities to direct attention or explain behavior
+
+2. **Understand the context**:
+   - What's the personality? (Playful vs serious, energetic vs calm)
+   - What's the performance budget? (Mobile-first? Complex page?)
+   - Who's the audience? (Motion-sensitive users? Power users who want speed?)
+   - What matters most? (One hero animation vs many micro-interactions?)
+
+If any of these are unclear from the codebase, ask the user directly to clarify what you cannot infer.
+
+**CRITICAL**: Respect `prefers-reduced-motion`. Always provide non-animated alternatives for users who need them.
+
+## Plan Animation Strategy
+
+Create a purposeful animation plan:
+
+- **Hero moment**: What's the ONE signature animation? (Page load? Hero section? Key interaction?)
+- **Feedback layer**: Which interactions need acknowledgment?
+- **Transition layer**: Which state changes need smoothing?
+- **Delight layer**: Where can we surprise and delight?
+
+**IMPORTANT**: One well-orchestrated experience beats scattered animations everywhere. Focus on high-impact moments.
+
+## Implement Animations
+
+Add motion systematically across these categories:
+
+### Entrance Animations
+- **Page load choreography**: Stagger element reveals (100-150ms delays), fade + slide combinations
+- **Hero section**: Dramatic entrance for primary content (scale, parallax, or creative effects)
+- **Content reveals**: Scroll-triggered animations using intersection observer
+- **Modal/drawer entry**: Smooth slide + fade, backdrop fade, focus management
+
+### Micro-interactions
+- **Button feedback**:
+  - Hover: Subtle scale (1.02-1.05), color shift, shadow increase
+  - Click: Quick scale down then up (0.95 → 1), ripple effect
+  - Loading: Spinner or pulse state
+- **Form interactions**:
+  - Input focus: Border color transition, slight scale or glow
+  - Validation: Shake on error, check mark on success, smooth color transitions
+- **Toggle switches**: Smooth slide + color transition (200-300ms)
+- **Checkboxes/radio**: Check mark animation, ripple effect
+- **Like/favorite**: Scale + rotation, particle effects, color transition
+
+### State Transitions
+- **Show/hide**: Fade + slide (not instant), appropriate timing (200-300ms)
+- **Expand/collapse**: Height transition with overflow handling, icon rotation
+- **Loading states**: Skeleton screen fades, spinner animations, progress bars
+- **Success/error**: Color transitions, icon animations, gentle scale pulse
+- **Enable/disable**: Opacity transitions, cursor changes
+
+### Navigation & Flow
+- **Page transitions**: Crossfade between routes, shared element transitions
+- **Tab switching**: Slide indicator, content fade/slide
+- **Carousel/slider**: Smooth transforms, snap points, momentum
+- **Scroll effects**: Parallax layers, sticky headers with state changes, scroll progress indicators
+
+### Feedback & Guidance
+- **Hover hints**: Tooltip fade-ins, cursor changes, element highlights
+- **Drag & drop**: Lift effect (shadow + scale), drop zone highlights, smooth repositioning
+- **Copy/paste**: Brief highlight flash on paste, "copied" confirmation
+- **Focus flow**: Highlight path through form or workflow
+
+### Delight Moments
+- **Empty states**: Subtle floating animations on illustrations
+- **Completed actions**: Confetti, check mark flourish, success celebrations
+- **Easter eggs**: Hidden interactions for discovery
+- **Contextual animation**: Weather effects, time-of-day themes, seasonal touches
+
+## Technical Implementation
+
+Use appropriate techniques for each animation:
+
+### Timing & Easing
+
+**Durations by purpose:**
+- **100-150ms**: Instant feedback (button press, toggle)
+- **200-300ms**: State changes (hover, menu open)
+- **300-500ms**: Layout changes (accordion, modal)
+- **500-800ms**: Entrance animations (page load)
+
+**Easing curves (use these, not CSS defaults):**
+```css
+/* Recommended - natural deceleration */
+--ease-out-quart: cubic-bezier(0.25, 1, 0.5, 1);    /* Smooth, refined */
+--ease-out-quint: cubic-bezier(0.22, 1, 0.36, 1);   /* Slightly snappier */
+--ease-out-expo: cubic-bezier(0.16, 1, 0.3, 1);     /* Confident, decisive */
+
+/* AVOID - feel dated and tacky */
+/* bounce: cubic-bezier(0.34, 1.56, 0.64, 1); */
+/* elastic: cubic-bezier(0.68, -0.6, 0.32, 1.6); */
+```
+
+**Exit animations are faster than entrances.** Use ~75% of enter duration.
+
+### CSS Animations
+```css
+/* Prefer for simple, declarative animations */
+- transitions for state changes
+- @keyframes for complex sequences
+- transform + opacity only (GPU-accelerated)
+```
+
+### JavaScript Animation
+```javascript
+/* Use for complex, interactive animations */
+- Web Animations API for programmatic control
+- Framer Motion for React
+- GSAP for complex sequences
+```
+
+### Performance
+- **GPU acceleration**: Use `transform` and `opacity`, avoid layout properties
+- **will-change**: Add sparingly for known expensive animations
+- **Reduce paint**: Minimize repaints, use `contain` where appropriate
+- **Monitor FPS**: Ensure 60fps on target devices
+
+### Accessibility
+```css
+@media (prefers-reduced-motion: reduce) {
+  * {
+    animation-duration: 0.01ms !important;
+    animation-iteration-count: 1 !important;
+    transition-duration: 0.01ms !important;
+  }
+}
+```
+
+**NEVER**:
+- Use bounce or elastic easing curves—they feel dated and draw attention to the animation itself
+- Animate layout properties (width, height, top, left)—use transform instead
+- Use durations over 500ms for feedback—it feels laggy
+- Animate without purpose—every animation needs a reason
+- Ignore `prefers-reduced-motion`—this is an accessibility violation
+- Animate everything—animation fatigue makes interfaces feel exhausting
+- Block interaction during animations unless intentional
+
+## Verify Quality
+
+Test animations thoroughly:
+
+- **Smooth at 60fps**: No jank on target devices
+- **Feels natural**: Easing curves feel organic, not robotic
+- **Appropriate timing**: Not too fast (jarring) or too slow (laggy)
+- **Reduced motion works**: Animations disabled or simplified appropriately
+- **Doesn't block**: Users can interact during/after animations
+- **Adds value**: Makes interface clearer or more delightful
+
+Remember: Motion should enhance understanding and provide feedback, not just add decoration. Animate with purpose, respect performance constraints, and always consider accessibility. Great animation is invisible - it just makes everything feel right.
