## What it does

The skill organizes twelve core principles into four functional groups: physics, clarity, interest, and technique. It focuses on how these rules interact. Faster motion demands more stretch to preserve apparent volume, while anticipation and follow-through function as visual bookends where the wind-up dictates the settle. Curved paths also require uneven spacing with frames clustered at the start and end.

Common coordination errors receive direct solutions. Uniform frame counts make movement look mechanical, and competing secondary actions distract from the main staging. The guide walks through a nine-step exercise of a character sitting down to demonstrate layered execution. You handle primary blocking first. Then you run separate refinement passes for each category.

Without hands-on experience applying individual principles first, these advanced combinations will feel overwhelming.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- Match anticipation scale to follow-through momentum
- Structure secondary actions so they do not compete with staging
- Apply easing along curved motion arcs
- Combine keyframe pose-to-pose blocking with straight-ahead follow-through

## Example prompts
- Review the timing and arcs for my character sitting down animation
- Help balance anticipation and follow-through on this jump sequence
- Break down a run cycle into blocking and principle refinement passes

# Combining Principles for Stronger Animation

You can apply individual principles. Now learn to weave them together and understand their interdependencies.

## Principle Synergies

### Squash/Stretch + Timing
Volume preservation is key. Faster motion = more stretch. The timing dictates the degree. A 2-frame anticipation needs less squash than a 6-frame one.

### Anticipation + Follow Through
These are mirrors. Anticipation magnitude should roughly match follow through. Big wind-up = big settle. They create rhythmic bookends to any action.

### Staging + Secondary Action
Secondary actions must support staging, never compete. If staging says "look at the face," secondary action in hands should point attention there, not away.

### Arcs + Slow In/Out
Arcs aren't uniform speeds. Apply easing along the arc path. Spacing should bunch at start/end of the arc, spread in the middle.

### Pose to Pose + Straight Ahead
Hybrid approach: Key poses first (pose-to-pose), then animate overlapping elements straight ahead. Best of both: structure with spontaneity.

## Common Combination Mistakes

**Over-anticipation:** When every action has massive wind-up, nothing feels spontaneous. Reserve big anticipation for big payoffs.

**Competing secondary actions:** Three things moving differently splits attention. Hierarchy matters - one leads, others support.

**Uniform timing:** Every action at 12 frames feels mechanical. Vary your timing: quick decisions, slow realizations.

**Arc neglect in follow through:** The main action arcs beautifully, then appendages move linearly. Everything arcs.

## The 12 Principles by Function

**Physics:** Squash/Stretch, Timing, Arcs, Slow In/Out
**Clarity:** Staging, Solid Drawing, Anticipation
**Interest:** Secondary Action, Exaggeration, Appeal
**Technique:** Straight Ahead/Pose to Pose, Follow Through/Overlap

## Integration Exercise

Animate a character sitting down:
1. **Staging:** Camera angle shows full body profile
2. **Anticipation:** Slight upward before descent
3. **Arcs:** Hips trace a curved path down
4. **Timing:** Faster drop, slower settle
5. **Squash:** Compress on contact
6. **Follow Through:** Arms/head continue after hips land
7. **Overlapping:** Hair settles last
8. **Secondary:** Adjusting clothing
9. **Slow Out:** Gradual stop to final pose
```
