## What it does

The skill maps Disney's 12 animation principles onto elements leaving view. The agent gets concrete rules: scale down to 95–98% on the way out, a brief hesitation before departure, and exits that head somewhere logical — deleted rows fall down, modals shrink back to their origin, sidebars return to their edge.

There is a timing table by element type: tooltips 100ms, dropdowns and toasts 150ms, modals and deleted items 200ms, page transitions 250ms, all ease-in. A CSS pattern ships with it, using `@keyframes` and `cubic-bezier(0.4, 0, 1, 1)`, plus a collapse sequence for removed list items: fade the content, collapse the height, then drop it from the DOM once the animation finishes.

The skill advises exits 20–30% faster than entrances and `will-change: opacity, transform`. If your project already has duration tokens, expect to reconcile them by hand — the skill hands out fixed numbers rather than reading them from a theme.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles exit-animations
```

gemini skills install https://github.com/dylantarre/animation-principles --path skills/05-by-animation-type/exit-animations
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- close a modal so it shrinks back to its origin instead of vanishing
- collapse a deleted list row without shoving its neighbours
- send a dismissed toast arcing up and out
- pick durations and easing for tooltips, dropdowns and page transitions
- make an exit finish faster than the matching entrance

## Example prompts
- Animate the modal close using the exit-animations skill: content fades first, overlay last
- When a task row is deleted it should collapse — apply exit-animations
- Set up the toast dismissal: 150ms, ease-in, arcing upward

# Exit Animations

Apply Disney's 12 principles when removing elements from view.

## Principle Application

**Squash & Stretch**: Scale down to 95-98% on exit. Element compresses slightly as it departs.

**Anticipation**: Brief pause or micro-movement before departure. A 50ms hesitation acknowledges the exit.

**Staging**: Exit toward logical destinations. Deleted items fall down, dismissed modals shrink to origin, sidebars return to their edge.

**Straight Ahead vs Pose-to-Pose**: Pose-to-pose with clear visible→invisible states. Plan the exit trajectory.

**Follow Through & Overlapping**: Content exits before container. Text fades 50ms before the card collapses.

**Slow In/Slow Out**: Use ease-in for exits. Gentle start, accelerating departure: `cubic-bezier(0.4, 0, 1, 1)`.

**Arcs**: Exit on curves, not straight lines. Dismissed notifications arc upward-and-out.

**Secondary Action**: Combine opacity fade with directional movement. Pure fades feel like errors.

**Timing**:
- Exits should be 20-30% faster than entrances
- Quick exits: 100-150ms (tooltips, dropdowns)
- Standard exits: 150-200ms (modals, toasts)
- Graceful exits: 200-300ms (page transitions)

**Exaggeration**: Scale to 0.9 for dramatic departure, 0.97 for subtle dismissal.

**Solid Drawing**: Maintain spatial logic. Elements should exit the way they came or toward where they "belong."

**Appeal**: Exits confirm user intent. Make dismissals feel decisive, not abrupt.

## Timing Recommendations

| Element Type | Duration | Easing | Notes |
|-------------|----------|--------|-------|
| Tooltip | 100ms | ease-in | Faster than entrance |
| Dropdown | 150ms | ease-in | Collapse upward |
| Toast | 150ms | ease-in | Slide to origin |
| Modal | 200ms | ease-in | Content first, overlay last |
| Deleted Item | 200ms | ease-in | Collapse height after fade |
| Page | 250ms | ease-in | Current page exits, then new enters |

## Implementation Pattern

```css
.exiting {
  animation: exit 200ms cubic-bezier(0.4, 0, 1, 1) forwards;
}

@keyframes exit {
  from {
    opacity: 1;
    transform: translateY(0) scale(1);
  }
  to {
    opacity: 0;
    transform: translateY(-10px) scale(0.98);
  }
}
```

## Collapse Pattern

For removed list items:
1. Fade out content (150ms)
2. Collapse height (150ms, starts at 100ms)
3. Remove from DOM after animation completes
