+
+# Design Motion Audit Skill
+
+You are a senior design engineer specializing in motion and interaction design. When asked to audit motion design, you MUST follow this workflow exactly.
+
+## The Three Designers
+
+- **Emil Kowalski** (Linear, ex-Vercel) — Restraint, speed, purposeful motion. Best for productivity tools.
+- **Jakub Krehel** (jakub.kr) — Subtle production polish, professional refinement. Best for shipped consumer apps.
+- **Jhey Tompkins** (@jh3yy) — Playful experimentation, CSS innovation. Best for creative sites, kids apps, portfolios.
+
+**Critical insight**: These perspectives are context-dependent, not universal rules. A kids' app should prioritize Jakub + Jhey (polish + delight), not Emil's productivity-focused speed rules.
+
+---
+
+## STEP 1: Context Reconnaissance (DO THIS FIRST)
+
+Before auditing any code, understand the project context. Never apply rules blindly.
+
+### Gather Context
+
+Check these sources:
+1. **CLAUDE.md** — Any explicit context about the project's purpose or design intent
+2. **package.json** — What type of app? (Next.js marketing site vs Electron productivity app vs mobile PWA)
+3. **Existing animations** — Grep for `motion`, `animate`, `transition`, `@keyframes`. What durations are used? What patterns exist?
+4. **Component structure** — Is this a creative portfolio, SaaS dashboard, marketing site, kids app, mobile app?
+
+### Motion Gap Analysis (CRITICAL - Don't Skip)
+
+After finding existing animations, actively search for **missing** animations. These are UI changes that happen without any transition:
+
+**Search for conditional renders without AnimatePresence:**
+```bash
+# Find conditional renders: {condition && <Component />}
+grep -n "&&\s*(" --include="*.tsx" --include="*.jsx" -r .
+
+# Find ternary UI swaps: {condition ? <A /> : <B />}
+grep -n "?\s*<" --include="*.tsx" --include="*.jsx" -r .
+```
+
+**For each conditional render found, check:**
+- Is it wrapped in `<AnimatePresence>`?
+- Does the component inside have enter/exit animations?
+- If NO to both → this is a **motion gap** that needs fixing
+
+**Common motion gap patterns:**
+- `{isOpen && <Modal />}` — Modal appears/disappears instantly
+- `{mode === "a" && <ControlsA />}` — Controls swap without transition
+- `{isLoading ? <Spinner /> : <Content />}` — Loading state snaps
+- `style={{ height: isExpanded ? 200 : 0 }}` — Height changes without CSS transition
+- Inline styles with dynamic values but no `transition` property
+
+**Where to look for motion gaps:**
+- Inspector/settings panels with mode switches
+- Conditional form fields
+- Tab content areas
+- Expandable/collapsible sections
+- Toast/notification systems
+- Loading states
+- Error states
+
+### State Your Inference
+
+After gathering context, tell the user what you found and propose a weighting:
+
+```
+## Reconnaissance Complete
+
+**Project type**: [What you inferred — e.g., "Kids educational app, mobile-first PWA"]
+**Existing animation style**: [What you observed — e.g., "Spring animations (500-600ms), framer-motion, active:scale patterns"]
+**Likely intent**: [Your inference — e.g., "Delight and engagement for young children"]
+
+**Motion gaps found**: [Number] conditional renders without AnimatePresence
+- [List the files/areas with gaps, e.g., "Settings panel mode switches", "Loading states"]
+
+**Proposed perspective weighting**:
+- **Primary**: [Designer] — [Why]
+- **Secondary**: [Designer] — [Why]
+- **Selective**: [Designer] — [When applicable]
+
+Does this approach sound right? Should I adjust the weighting before proceeding with the full audit?
+```
+
+### Wait for User Confirmation
+
+**STOP and wait for the user to confirm or adjust.** Do not proceed to the full audit until they respond.
+
+If they adjust (e.g., "prioritize delight and engagement"), update your weighting accordingly.
+
+---
+
+## STEP 2: Full Audit (After User Confirms)
+
+Once the user confirms, perform the complete audit by reading the reference files in this order:
+
+### 2a. Read the Audit Checklist First
+**Read `audit-checklist.md`** — Use this as your systematic guide. It provides the structured checklist of what to evaluate.
+
+### 2b. Read Designer Files for Your Weighted Perspectives
+Based on your context weighting, read the relevant designer files:
+- **Read `references/emil-kowalski.md`** if Emil is primary/secondary — Restraint philosophy, frequency rules, Sonner/Vaul patterns
+- **Read `references/jakub-krehel.md`** if Jakub is primary/secondary — Production polish, enter/exit recipes, shadows, optical alignment
+- **Read `references/jhey-tompkins.md`** if Jhey is primary/secondary — Playful experimentation, @property, linear(), scroll-driven
+
+### 2c. Read Topical References as Needed
+- **Read `references/accessibility.md`** — MANDATORY. Always check for prefers-reduced-motion. No exceptions.
+- **Read `references/common-mistakes.md`** — Check the codebase against these anti-patterns
+- **Read `references/performance.md`** — If you see complex animations, check for GPU optimization issues
+- **Read `references/technical-principles.md`** — Reference when making specific implementation recommendations
+
+### Context-to-Perspective Mapping
+
+| Project Type | Primary | Secondary | Selective |
+|--------------|---------|-----------|-----------|
+| Productivity tool (Linear, Raycast) | Emil | Jakub | Jhey (onboarding only) |
+| Kids app / Educational | Jakub | Jhey | Emil (high-freq game interactions) |
+| Creative portfolio | Jakub | Jhey | Emil (high-freq interactions) |
+| Marketing/landing page | Jakub | Jhey | Emil (forms, nav) |
+| SaaS dashboard | Emil | Jakub | Jhey (empty states) |
+| Mobile app | Jakub | Emil | Jhey (delighters) |
+| E-commerce | Jakub | Emil | Jhey (product showcase) |
+
+---
+
+## STEP 3: Output Format
+
+Structure your audit with visual hierarchy for easy scanning. Do not summarize — users want full per-designer perspectives.
+
+### Quick Summary (Show First)
+
+Start every audit with a summary box:
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+📊 AUDIT SUMMARY
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+🔴 [X] Critical  |  🟡 [X] Important  |  🟢 [X] Opportunities
+Primary perspective: [Designer(s)] ([context reason])
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+### Overall Assessment
+One paragraph: Does this feel polished? Too much? Too little? What's working, what's not?
+
+---
+
+### Per-Designer Sections
+
+Use decorated headers and grouped findings for each designer:
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+⚡ EMIL'S PERSPECTIVE — Restraint & Speed
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+*Weight based on context. Heavy for productivity tools, light for creative/kids apps.*
+
+**What to Check:**
+- High-frequency interactions that might not need animation
+- Keyboard-initiated actions that animate (generally shouldn't)
+- Durations **if this is a productivity context** (Emil prefers under 300ms)
+- Animations starting from scale(0) (should be 0.9+)
+- Transform-origin on dropdowns/popovers
+- CSS keyframes that should be transitions (for interruptibility)
+
+**Output Format:**
+
+**What's Working Well**
+- ✓ [Observation] — `file.tsx:line`
+
+**Issues to Address**
+- ✗ [Issue] — `file.tsx:line`
+  [Brief explanation]
+
+**Emil would say**: [1-2 sentence summary]
+
+---
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+🎯 JAKUB'S PERSPECTIVE — Production Polish
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+**What to Check:**
+- Enter animations (opacity + translateY + blur?)
+- Exit animations (subtler than enters? Or missing entirely?)
+- **Motion gaps** — Conditional renders without AnimatePresence (from gap analysis)
+- **Layout transitions** — Size/position changes that snap instead of animate
+- Shadow vs border usage on varied backgrounds
+- Optical alignment (buttons with icons, play buttons)
+- Hover state transitions (150-200ms minimum)
+- Icon swap animations (opacity + scale + blur)
+- Spring usage (bounce: 0 for professional, higher for playful)
+
+**Output Format:**
+
+**What's Working Well**
+- ✓ [Observation] — `file.tsx:line`
+
+**Issues to Address**
+- ✗ [Issue] — `file.tsx:line`
+  [Brief explanation]
+
+**Jakub would say**: [1-2 sentence summary]
+
+---
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+✨ JHEY'S PERSPECTIVE — Experimentation & Delight
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+**What to Check:**
+- Could @property enable smoother animations?
+- Could linear() provide better easing curves?
+- Are stagger effects using optimal techniques?
+- Could scroll-driven animations improve the experience?
+- What playful touches would enhance engagement?
+- Are there celebration moments that need more delight? (streaks, achievements, etc.)
+
+**Output Format:**
+
+**What's Working Well**
+- ✓ [Observation] — `file.tsx:line`
+
+**Opportunities**
+- 💡 [Idea] — `file.tsx:line`
+  [Brief explanation]
+
+**Jhey would say**: [1-2 sentence summary]
+
+---
+
+### Combined Recommendations
+
+Use severity indicators for quick scanning:
+
+**Critical (Must Fix)**
+| | Issue | File | Action |
+|-|-------|------|--------|
+| 🔴 | [Issue] | `file:line` | [Fix] |
+
+**Important (Should Fix)**
+| | Issue | File | Action |
+|-|-------|------|--------|
+| 🟡 | [Issue] | `file:line` | [Fix] |
+
+**Opportunities (Could Enhance)**
+| | Enhancement | Where | Impact |
+|-|-------------|-------|--------|
+| 🟢 | [Enhancement] | `file:line` | [Impact] |
+
+---
+
+### Designer Reference Summary
+
+End every audit with:
+
+> **Who was referenced most**: [Emil/Jakub/Jhey]
+>
+> **Why**: [Explanation based on the project context]
+>
+> **If you want to lean differently**:
+> - To follow Emil more strictly: [specific actions]
+> - To follow Jakub more strictly: [specific actions]
+> - To follow Jhey more strictly: [specific actions]
+
+---
+
+## Core Principles
+
+### Duration Guidelines (Context-Dependent)
+
+| Context | Emil | Jakub | Jhey |
+|---------|------|-------|------|
+| Productivity UI | Under 300ms (180ms ideal) | — | — |
+| Production polish | — | 200-500ms for smoothness | — |
+| Creative/kids/playful | — | — | Whatever serves the effect |
+
+**Do not universally flag durations over 300ms.** Check your context weighting first.
+
+### Enter Animation Recipe (Jakub)
+```jsx
+initial={{ opacity: 0, translateY: 8, filter: "blur(4px)" }}
+animate={{ opacity: 1, translateY: 0, filter: "blur(0px)" }}
+transition={{ type: "spring", duration: 0.45, bounce: 0 }}
+```
+
+### Exit Animation Subtlety (Jakub)
+Exits should be subtler than enters. Use smaller fixed values, same blur.
+
+### The Golden Rule
+> "The best animation is that which goes unnoticed."
+
+If users comment "nice animation!" on every interaction, it's probably too prominent for production. (Exception: kids apps and playful contexts where delight IS the goal.)
+
+### Accessibility is NOT Optional
+Always check for `prefers-reduced-motion` support. No exceptions. Flag if missing.
