## What it does

This skill turns animation troubleshooting into a systematic checklist. Instead of guessing why an interaction feels clunky, your coding agent evaluates motion against the 12 classic Disney principles. It matches symptoms like rigid movements, abrupt stops, or visual glitches to direct CSS and motion adjustments.

The framework includes timing targets: 100 to 200 ms for micro-interactions and 200 to 400 ms for transitions. To keep GPU rendering smooth, it insists on animating only `transform` and `opacity`.

If an animation breaks accessibility, fails `prefers-reduced-motion`, or delays task completion, the rules state you should delete it altogether.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill universal-solutions -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/universal-solutions/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/universal-solutions/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill universal-solutions -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/universal-solutions/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill universal-solutions -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/universal-solutions/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles universal-solutions
```

2. **Manually: put the files in place**
- File: `.github/skills/universal-solutions/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill universal-solutions -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/12-by-problem-type/universal-solutions
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/universal-solutions/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill universal-solutions -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dylantarre/animation-principles/tree/HEAD/skills/12-by-problem-type/universal-solutions/SKILL.md

## When to use it
- diagnose robotic or abrupt UI transitions
- calibrate durations for micro-interactions and modal dialogs
- eliminate GPU glitches by restricting properties to `transform` and `opacity`
- check compliance with `prefers-reduced-motion`

## Example prompts
- Audit this button press effect using the universal-solutions checklist
- Why does this modal transition feel jarring? Apply the 12 animation principles
- Check our navigation drawer animation for easing issues and performance bottlenecks

# Universal Animation Solutions

A complete diagnostic framework using all 12 Disney principles.

## The 12 Principles Checklist

Run through each principle to diagnose any animation problem:

### 1. Squash and Stretch
**Check**: Is there appropriate flexibility?
**Problem sign**: Rigid, lifeless motion
**Fix**: Add subtle scale changes on impact/acceleration

### 2. Anticipation
**Check**: Is there buildup before action?
**Problem sign**: Actions feel sudden or surprising
**Fix**: Add small reverse movement or wind-up

### 3. Staging
**Check**: Is the important thing clear?
**Problem sign**: Users miss key information
**Fix**: Isolate animated element, reduce competing motion

### 4. Straight Ahead vs Pose-to-Pose
**Check**: Is the approach right for the effect?
**Problem sign**: Uncontrolled or too rigid motion
**Fix**: Use keyframes for UI; frame-by-frame for organic

### 5. Follow Through
**Check**: Do things settle naturally?
**Problem sign**: Abrupt, mechanical endings
**Fix**: Add overshoot and settle, or soft deceleration

### 6. Slow In and Slow Out
**Check**: Is there proper easing?
**Problem sign**: Robotic, linear motion
**Fix**: Apply ease-out for entrances, ease-in for exits

### 7. Arcs
**Check**: Is the motion path natural?
**Problem sign**: Unnatural straight-line movement
**Fix**: Add curved paths for organic motion

### 8. Secondary Action
**Check**: Do supporting elements enhance?
**Problem sign**: Flat, one-dimensional animation
**Fix**: Add subtle complementary movements

### 9. Timing
**Check**: Is the speed appropriate?
**Problem sign**: Too fast or too slow
**Fix**: Micro: 100-200ms, Transitions: 200-400ms

### 10. Exaggeration
**Check**: Is the drama level right?
**Problem sign**: Too subtle or too dramatic
**Fix**: Match exaggeration to context importance

### 11. Solid Drawing
**Check**: Is rendering correct?
**Problem sign**: Visual glitches, distortion
**Fix**: Use transform/opacity only, check GPU layers

### 12. Appeal
**Check**: Does it feel right?
**Problem sign**: Hard to articulate wrongness
**Fix**: Align motion with brand/emotional intent

## Quick Diagnostic

1. **Describe the problem** in one sentence
2. **Identify which principle** relates most directly
3. **Check adjacent principles** (problems cluster)
4. **Apply targeted fix** from that principle

## Master Troubleshooting Checklist

- [ ] Does animation serve a purpose?
- [ ] Is timing appropriate (usually 150-300ms)?
- [ ] Is easing applied (not linear)?
- [ ] Does it respect `prefers-reduced-motion`?
- [ ] Is only transform/opacity being animated?
- [ ] Is motion guiding attention correctly?
- [ ] Does it match brand/emotional context?
- [ ] Can users complete tasks without it?
