## What it does

This skill injects a concise 12-principles checklist, a symptom diagnosis table, and a pre-flight shot checklist into the assistant's context. It omits introductory animation theory entirely, focusing on direct calibrations such as the silhouette test, root-leads-tips hierarchy, and pushing exaggeration 20% past reality.

The reference includes diagnostic pointers to troubleshoot specific motion issues: floaty timing, stiffness, lack of overlap, or mechanical arcs. It also outlines principle hierarchies matched to specific shot genres, including action scenes, dialogue shots, comedy, and subtle acting.

Because the skill contains only structured guidelines without external scripts, it requires no runtime dependencies or API credentials. It deliberately targets experienced animators; beginners will find no foundational tutorials or step-by-step breakdowns here.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill refresher -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/04-by-skill-level/refresher/SKILL.md

## When to use it
- Audit an animation shot against core principles before delivery
- Diagnose reasons behind stiff, floaty, or lifeless movement
- Prioritize animation principles for action, comedy, or dialogue scenes
- Correct mechanical motion paths and balance spacing charts

## Example prompts
- Review this sword swing animation: the movement feels too mechanical and floaty
- Help me prioritize animation principles for a character dialogue shot
- The jump sequence feels stiff and lacks weight. What should I check in spacing and overlap?

# Quick Principles Refresher

You know these. Here's the checklist.

## The 12

1. **Squash/Stretch** - Volume constant, shape varies. Check your impacts and fast motion.

2. **Anticipation** - Is the audience prepared? Opposite direction, proportional to action.

3. **Staging** - Silhouette test. One idea. Where's the eye going?

4. **Straight Ahead / Pose to Pose** - Right method for this shot? Maybe hybrid.

5. **Follow Through / Overlap** - Does everything stop at once? (It shouldn't.) Hierarchy: root leads, tips lag.

6. **Slow In / Out** - Checked your spacing charts? Bunched at ends, spread in middle.

7. **Arcs** - Track the paths. Everything curves unless intentionally broken.

8. **Secondary Action** - Supporting, not competing. Add after primary works.

9. **Timing** - Frame count matches intent? Weight, mood, pacing all live here.

10. **Exaggeration** - Did you push it enough? (Probably not.) Find real, then go 20% past.

11. **Solid Drawing** - Does it have weight? Volume consistent through motion?

12. **Appeal** - Would you watch this? Clear shapes, readable pose, distinctive design?

## Quick Diagnosis

**Floaty?** Check timing and slow in/out. Probably too even.

**Stiff?** Add overlap. Offset timing. Break symmetry.

**Confusing?** Staging issue. Simplify. One idea per shot.

**Mechanical?** Arcs are probably too straight. Add anticipation variety.

**Dead?** Secondary action missing. Overlap insufficient.

**Boring?** Push exaggeration. Check appeal. Vary timing.

## Shot Checklist

Before calling it done:

- [ ] Silhouette reads
- [ ] Arcs tracked
- [ ] Spacing varied (slow in/out)
- [ ] Overlap on all appendages
- [ ] Secondary action supports (doesn't compete)
- [ ] Exaggeration appropriate to style
- [ ] Timing matches weight and mood
- [ ] Anticipation proportional
- [ ] Volume consistent
- [ ] Appeal present

## Principle Priority by Shot Type

**Action:** Timing > Arcs > Anticipation > Squash/Stretch
**Dialogue:** Staging > Secondary > Timing > Appeal
**Comedy:** Timing > Exaggeration > Anticipation > Staging
**Subtle acting:** Secondary > Overlap > Timing > Staging

Trust your instincts. You've done this. This is just calibration.
