## What it does

The skill injects animation principles into agent instructions, tuning them for fast user feedback. It sets specific parameters for dynamic motion, including 20-35% squash and stretch alongside 100-150ms anticipation phases. These guidelines steer the coding agent away from sluggish generic transitions toward responsive, spring-like movements.

It provides ready-made CSS easing tokens such as `--energy-snap` and `--energy-bounce`. Prebuilt `@keyframes` templates cover shake and burst patterns. The skill enforces aggressive acceleration curves like `cubic-bezier(0.0, 0, 0.2, 1)`, so animations snap immediately instead of easing gently.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles excitement-energy
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill excitement-energy -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/06-by-emotional-outcome/excitement-energy/SKILL.md

## When to use it
- build snappy button click animations with fast easing
- implement `energy-burst` keyframes for modal reveals
- configure custom `cubic-bezier` timing for reactive UI components
- coordinate anticipation and bounce phases within 100–400ms intervals

## Example prompts
- "Apply an energetic pulse animation to this CTA button using `--energy-punch`"
- "Create a high-impact product card reveal following the steps in `excitement-energy`"
- "Generate CSS shake keyframes for invalid inputs with a 100-150ms duration"

# Excitement & Energy Animation

Create animations that energize, excite, and create dynamic, high-impact experiences.

## Emotional Goal

Excitement builds through dynamic, escalating motion. Energy comes from fast, varied animations that create momentum and keep users engaged.

## Disney Principles for Excitement

### Squash & Stretch
Dynamic and impactful (20-35%). High-energy compression and extension. Objects feel springy and responsive.

### Anticipation
Quick, building tension (100-150ms). Like a coiled spring. The anticipation itself creates excitement.

### Staging
Dynamic compositions. Diagonal lines, asymmetric layouts. Nothing static—energy in every arrangement.

### Straight Ahead Action
Embrace for particle effects, explosions, and dynamic backgrounds. Energetic spontaneity.

### Follow Through & Overlapping Action
Bouncy, energetic overshoot. Elements don't just stop—they rebound with vitality.

### Slow In & Slow Out
Aggressive acceleration curves. Fast starts, snappy stops. `cubic-bezier(0.0, 0, 0.2, 1)` for punch.

### Arc
Dramatic, sweeping paths. High trajectories, dynamic curves. Motion that commands attention.

### Secondary Action
Abundant energy effects. Particles, trails, glows. The environment responds to exciting moments.

### Timing
Fast and punchy (100-300ms). Rapid sequences. Variety in timing creates rhythm and energy.

### Exaggeration
High (25-40%). Push movements to feel impactful. Energy requires going beyond subtle.

### Solid Drawing
Dynamic poses and forms. Lean into motion. Shapes that convey speed and force.

### Appeal
Bold, high-contrast design. Saturated colors. Dynamic angles. Visual energy.

## Timing Recommendations

| Element | Duration | Easing |
|---------|----------|--------|
| Quick hit | 100-150ms | `ease-out` |
| Bounce | 300-400ms | `spring` |
| Reveal | 200-300ms | `ease-out` |
| Sequence step | 50-100ms | `ease-out` |

## CSS Easing

```css
--energy-snap: cubic-bezier(0.0, 0, 0.2, 1);
--energy-bounce: cubic-bezier(0.34, 1.56, 0.64, 1);
--energy-punch: cubic-bezier(0.22, 1, 0.36, 1);
```

## High-Energy Patterns

```css
@keyframes energy-burst {
  0% {
    transform: scale(0.8);
    opacity: 0;
  }
  50% {
    transform: scale(1.1);
  }
  100% {
    transform: scale(1);
    opacity: 1;
  }
}

@keyframes energy-shake {
  0%, 100% { transform: translateX(0); }
  10%, 30%, 50%, 70%, 90% { transform: translateX(-4px); }
  20%, 40%, 60%, 80% { transform: translateX(4px); }
}

@keyframes energy-pulse {
  0%, 100% { transform: scale(1); }
  50% { transform: scale(1.08); }
}
```

## Building Energy

1. Start with anticipation build
2. Quick, impactful main action
3. Energetic follow-through
4. Secondary effects cascade
