## What it does

This skill provides design instructions based on Disney animation principles adjusted for approachable UI motion. It sets boundaries for anticipation (100-150ms), mild exaggeration (10-20%), and comfortable timing between 200ms and 350ms. The goal is subtle human feedback rather than abrupt or cartoonish movements.

It supplies ready CSS cubic-bezier curves (`--friendly-ease`, `--friendly-enter`, `--friendly-bounce`) alongside keyframe snippets for welcoming reveals and waves. Sharp paths and harsh accelerations will break the intended effect: motions favor soft `ease-out` decrescendo curves and animate toward the user.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles friendliness-approachability
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

### Claude.ai

## When to use it
- configure gentle entrance transitions for onboarding steps
- set cubic-bezier curves for friendly UI feedback
- fine-tune hover durations and anticipation timings
- build non-intrusive micro-interactions for support widgets

## Example prompts
- Apply friendliness-approachability guidelines to animate our welcome dialog
- Set up CSS transitions for the support widget buttons using friendliness-approachability easing
- Create a gentle wave keyframe animation for the onboarding avatar

# Friendliness & Approachability Animation

Create animations that welcome users and make interfaces feel warm and inviting.

## Emotional Goal

Friendliness comes from gentle, welcoming motion that doesn't intimidate. Approachability means animations that invite interaction and make users feel comfortable.

## Disney Principles for Friendliness

### Squash & Stretch
Moderate, soft deformation (10-20%). Enough to feel alive without being cartoonish. Like a friendly handshake—warm but appropriate.

### Anticipation
Gentle preparation (100-150ms). Friendly motion telegraphs intention without startling. A small "hello" before action.

### Staging
Open, inviting compositions. Elements arranged to welcome, not confront. Clear pathways into the interface.

### Straight Ahead Action
Light spontaneity for personality. Subtle variations that feel human and approachable rather than mechanical.

### Follow Through & Overlapping Action
Soft, natural settling. A gentle bounce or two. Like a friend sitting down beside you—relaxed, not rigid.

### Slow In & Slow Out
Smooth, approachable curves. No sharp accelerations. `ease-out` for welcoming entrances that arrive gently.

### Arc
Natural, relaxed curves. Motion that feels human—not robotic straight lines, not exaggerated bounces.

### Secondary Action
Warm supporting gestures. A subtle wave, a gentle nod. Elements acknowledge user presence.

### Timing
Moderate, comfortable (200-350ms). Not rushed, not sluggish. Conversational pacing that feels natural.

### Exaggeration
Mild (10-20%). Enough personality to feel warm without being overwhelming. Relatable, not theatrical.

### Solid Drawing
Soft, rounded forms. Approachable proportions. Nothing sharp or intimidating.

### Appeal
Warm colors, rounded corners. Friendly faces when appropriate. Inviting, accessible aesthetics.

## Timing Recommendations

| Element | Duration | Easing |
|---------|----------|--------|
| Welcome fade | 250-350ms | `ease-out` |
| Slide in | 300-400ms | `ease-out` |
| Hover response | 150-200ms | `ease-out` |
| Expand/reveal | 250-350ms | `ease-in-out` |

## CSS Easing

```css
--friendly-ease: cubic-bezier(0.25, 0.1, 0.25, 1);
--friendly-enter: cubic-bezier(0.0, 0, 0.2, 1);
--friendly-bounce: cubic-bezier(0.34, 1.3, 0.64, 1);
```

## Welcoming Patterns

```css
@keyframes friendly-wave {
  0%, 100% { transform: rotate(0deg); }
  20% { transform: rotate(14deg); }
  40% { transform: rotate(-8deg); }
  60% { transform: rotate(10deg); }
  80% { transform: rotate(-4deg); }
}

@keyframes friendly-appear {
  from {
    opacity: 0;
````
