## What it does

The skill covers how experienced animators step away from the classic principles and what that buys on screen. It walks through specific moves: rigid motion without squash and stretch, dropping anticipation for hard cuts, deliberately awkward staging, linear timing, broken arcs, conflicting secondary action.

Each technique comes with examples from animation, from Spirited Away to Into the Spider-Verse. There are no presets here. The point is the reasoning: when a violation reads as expressive, and when it just looks like a mistake. A closing section folds the principles into one holistic view, where technique serves story and emotion.

Worth installing if you already handle the fundamentals and want to stretch them on purpose. Without that base the skill has nothing to stand on, because it assumes you can apply the principles before you subvert them.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- explain why an animator deliberately breaks a classic principle
- pick a technique for a hard-cut scene with no anticipation
- separate two characters' styles through different motion arcs
- make motion feel mechanical or otherworldly by dropping squash
- show a character's inner conflict through contradictory secondary action

## Example prompts
- Break down how the missing anticipation works in this scene and what it gives compared to the classic approach
- Help me choose between linear timing and ease for a mechanical character
- Explain when broken motion arcs are appropriate and when they read as a mistake

# Transcending the Principles

Mastery means knowing when to break rules. The principles are training wheels for intuition. Here's how experts leverage, subvert, and transcend them.

## Intentional Violations

### Anti-Squash/Stretch
Rigid motion creates uncanny, mechanical, or ethereal qualities. Spirited Away's gods move without squash - otherworldly presence. Perfect volume preservation can feel more alien than violations.

### Omitted Anticipation
Into the Spider-Verse removes anticipation for snap cuts that feel like comic panels. Absence of anticipation = visual punctuation. Anticipation's removal is a choice, not an error.

### Anti-Staging
David Lynch deliberately obscures important elements. Burying the point creates unease, mystery, viewer work. Strategic confusion can be the goal.

### Pure Methods
Some masters work exclusively straight ahead (James Baxter's creature animation) or purely pose-to-pose (limited animation's stylized precision). Constraint breeds innovation.

### Stopped Follow Through
Freezing follow through mid-motion creates held tension. Anime uses this for impact frames. The principle's interruption is the effect.

### Linear Timing
Removing ease creates robotic precision or dreamlike float. Linear spacing isn't wrong - it's a vocabulary choice for specific effects.

### Broken Arcs
Jerky, angular paths for insects, robots, or psychological breaks. Spider-Man: Into the Spider-Verse uses broken arcs for Miles vs. smooth arcs for Peter.

### Conflicting Secondary Action
Body language contradicting primary action reveals character complexity. Smiling while clenching fists. Agreement words with disagreement gestures.

### Wrong Timing
Comedy often uses "incorrect" timing. Delayed reactions, impossibly fast actions, freeze frames - timing violations for comic effect.

### Reduced Exaggeration
Hyperrealism in animation (rotoscope, mo-cap) deliberately minimizes exaggeration. The uncanny valley is sometimes the destination.

### Flat Drawing
UPA style, Samurai Jack - intentional flatness as graphic design. Solid drawing exists so you can meaningfully reject dimension.

### Uncomfortable Appeal
Ren & Stimpy's "appeal" repulses. The magnetic quality of grotesque. Appeal redefined as compelling attention, not pleasant aesthetics.
