A skill for animators who already know the fundamentals and want the nuances: invisible squash/stretch, missing anticipation, deliberately broken arcs.

## What it does

The skill walks through twelve animation principles at an advanced level. Squash and stretch in facial work — brows compressing, cheeks stretching, jaw volume shifting — happens below conscious notice. Anticipation can be dropped on purpose: a punch with no wind-up reads as a surprise. Staging covers negative space, and an empty frame builds tension.

Method choice depends on the scene. Straight ahead gives emotional spontaneity in performance, pose-to-pose gives precise timing in action, and some shots switch mid-way. Follow through carries emotional subtext: heavy reads as reluctance or fatigue, minimal as alertness. A separate section weighs principles by genre — timing, arcs and anticipation dominate action, while comedy leans on timing, exaggeration and staging.

This is material for working animators, not beginners. Without the fundamentals already in hand, most of it won't land. Examples reference specific styles: Pixar exaggeration differs from Genndy Tartakovsky's, and what works in Looney Tunes wrecks Ghibli realism. Worth checking against your project's visual language before pulling any of it into production.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/04-by-skill-level/advanced
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

### Claude.ai

**Claude.ai**

## When to use it
- understand how squash and stretch read in facial animation without being noticed
- decide when dropping anticipation makes a hit or a gag land harder
- pick between straight ahead and pose-to-pose for a given scene
- weight principles by genre: action, comedy, drama or horror
- break an arc on purpose for a robot or a physical impact

## Example prompts
- Break down this scene: where should I drop anticipation so the punch reads as a surprise?
- Which method fits an emotional monologue — straight ahead or pose-to-pose?
- Weight the principles for a horror scene and tell me what to break deliberately.

# Nuanced Application of Animation Principles

You've internalized the fundamentals. Now explore the subtleties that separate competent from exceptional animation.

## Beyond the Basics

### Squash and Stretch: The Invisible Application
Facial animation relies on subtle squash/stretch most viewers never consciously see. Brows compress, cheeks stretch, jaw volumes shift. The principle applies to rigid objects too - camera shake and motion blur are perceptual squash/stretch.

### Anticipation: When to Subvert It
Lack of anticipation creates surprise, shock, comedy. A punch without wind-up reads as unexpected. Master animators use anticipation's *absence* as deliberately as its presence.

### Staging: Negative Space as Tool
What you don't show matters. Empty frame space creates tension. Cramped staging creates claustrophobia. Staging includes compositional psychology, not just visibility.

### Method Selection: Scene-Dependent Choices
Straight ahead for emotional spontaneity in performance. Pose-to-pose for precision timing in action. The choice shapes the final energy. Some scenes demand switching methods mid-shot.

### Follow Through: Emotional Resonance
Heavy follow through suggests reluctance, weight, sadness. Minimal follow through suggests alertness, tension. The technical principle carries emotional subtext.

### Slow In/Out: Non-Linear Easing
Beyond basic ease curves: snap with overshoot, settle with micro-bounces, hold with drift. Custom spacing graphs for specific emotional beats.

### Arcs: Broken Arcs as Choice
Robotic characters, sudden decisions, physical impacts - these break arcs intentionally. The principle teaches natural motion so you can meaningfully deviate.

### Secondary Action: Counterpoint
Advanced secondary action can contrast the primary emotion. Happy walk with nervous hand-wringing hints at hidden anxiety. Layers create complexity.

### Timing: Frame-by-Frame Psychology
