## What it does

This skill covers motion design for screens where the goal is reassurance. It walks through the classic animation principles and turns them into numbers: soft squash & stretch kept at 5-10%, clear anticipation of 150-200ms so nothing appears out of nowhere, gentle easing curves throughout. Straight ahead action is ruled out on purpose. Predictability beats expressiveness here.

You get a timing table by element type: transitions 300-400ms, feedback 200-250ms, confirmation 350-450ms, protection reveal 400-500ms, each with its easing. Alongside it are CSS custom properties built on cubic-bezier and two keyframes — `comfort-embrace` for a soft entrance and `comfort-check` for drawing a checkmark via `stroke-dashoffset`. A separate list covers safety signals: visible feedback on every action, undo animations that show reversibility, progress that never jumps backward.

Banking, healthcare, password and privacy flows, insurance, backup and recovery — that is the territory. If you already write CSS animations, the values drop in as-is; adapting them to your own design system is on you.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles comfort-safety
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/06-by-emotional-outcome/comfort-safety
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- reassure a user at the moment a payment is confirmed
- show that data was saved and nothing was lost
- make undo visible and clearly reversible
- walk someone through a password change without alarm
- present privacy settings as calm, predictable steps

## Example prompts
- animate the transfer confirmation using the comfort-safety skill
- check the timing on the password change screen against comfort-safety
- add the comfort-check keyframes for the saved checkmark

# Comfort & Safety Animation

Create animations that reassure, protect, and make users feel secure.

## Emotional Goal

Comfort comes from predictable, gentle motion that never startles. Safety means animations that communicate protection, stability, and user control.

## Disney Principles for Comfort

### Squash & Stretch
Minimal, soft (5-10%). Gentle give without instability. Like a cushion—absorbs impact, maintains structure.

### Anticipation
Clear, reassuring preparation (150-200ms). Users always know what's coming. No surprises, no hidden actions.

### Staging
Enclosed, protected compositions. Clear boundaries. Safe spaces. Visual hierarchy that guides without overwhelming.

### Straight Ahead Action
Avoid. Safety requires predictability. Every movement should be controlled and expected.

### Follow Through & Overlapping Action
Gentle, cushioned settling. Soft landings. Elements ease into place like being tucked in.

### Slow In & Slow Out
Smooth, gentle curves throughout. No sudden changes. `ease-in-out` for predictable, comfortable motion.

### Arc
Soft, natural curves. Cradling, embracing paths. Motion that wraps around rather than cuts through.

### Secondary Action
Reassuring cues only. Checkmarks, shields, locks. Visual confirmation of safety and completion.

### Timing
Moderate, unhurried (300-450ms). Time to process and feel safe. Never rushed or abrupt.

### Exaggeration
None to minimal. Realistic, grounded movements. Comfort requires believability.

### Solid Drawing
Stable, balanced forms. Low center of gravity. Shapes that feel grounded and secure.

### Appeal
Warm, muted colors. Soft edges. Familiar, comfortable aesthetics. Nothing aggressive or sharp.

## Timing Recommendations

| Element | Duration | Easing |
|---------|----------|--------|
| Transitions | 300-400ms | `ease-in-out` |
| Feedback | 200-250ms | `ease-out` |
| Confirmation | 350-450ms | `ease-out` |
| Protection reveal | 400-500ms | `ease-in-out` |

## CSS Easing

```css
--comfort-smooth: cubic-bezier(0.4, 0, 0.2, 1);
--comfort-gentle: cubic-bezier(0.45, 0, 0.55, 1);
--comfort-settle: cubic-bezier(0.25, 0.1, 0.25, 1);
```

## Reassuring Patterns

```css
@keyframes comfort-embrace {
  from {
    opacity: 0;
    transform: scale(0.98);
  }
  to {
    opacity: 1;
    transform: scale(1);
  }
}

@keyframes comfort-check {
  0% {
    stroke-dashoffset: 24;
    opacity: 0;
  }
````
