# Animation Principles - Troubleshooting

A skill that diagnoses why an animation feels wrong and points to the principle being misapplied. Useful when the motion reads badly but the cause is unclear.

## What it does

The skill acts as a symptom-based diagnostic guide. You describe what feels off — floaty, stiff, unreadable — and get a checklist of what to inspect: spacing, timing, squash and stretch, follow through. Each symptom comes with a short fix.

A separate section covers principle conflicts. Big anticipation kills surprise, heavy follow through softens snappy timing, secondary action can distract from the primary one. You have to choose deliberately. There are last-resort steps too: return to blocking, strip out all overlap and secondary motion, and see whether the primary action holds up alone.

When several principles fail at once, the skill says to fix timing and arcs first. Everything else depends on them, so working in another order often goes nowhere.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- find out why an animation feels floaty
- remove stiff, robotic motion
- make an action readable to the viewer
- bring a lifeless scene back with secondary action
- locate the broken arc when nothing obvious is wrong

## Example prompts
- My character animation feels floaty, help me find the cause
- The motion looks stiff, which principles should I check
- Something is off with this animation — run it through the symptoms

# Animation Troubleshooting Guide

Something's off. Use this to find and fix it.

## Symptom-Based Diagnosis

### "It feels floaty/weightless"
**Check:**
- Slow in/out - Is spacing too even? Add bunching at start/end
- Timing - Need more frames for weight? Fewer for snap?
- Squash/stretch - Impact reaction visible?
- Follow through - Settling properly or just stopping?

**Fix:** Add 2-4 frames to settle. Increase spacing variation. Add impact squash.

### "It feels stiff/robotic"
**Check:**
- Arcs - Are paths too straight?
- Overlap - Is everything moving at once?
- Secondary action - Is it present?
- Anticipation - Too uniform?

**Fix:** Offset timing between body parts. Curve your motion paths. Vary anticipation amounts.

### "I can't tell what's happening"
**Check:**
- Staging - Silhouette clear?
- Anticipation - Is viewer prepared for action?
- Timing - Too fast to read?
- Exaggeration - Key poses pushed enough?

**Fix:** Simplify composition. Add anticipation frames. Extend key poses. Push silhouette.

### "It feels dead/lifeless"
**Check:**
- Secondary action - Present and supporting?
- Overlap - Different parts moving differently?
- Timing - Varied or monotonous?
- Appeal - Character design working?

**Fix:** Layer in secondary actions. Offset everything by 1-3 frames. Vary timing between actions.

### "It feels cartoony when it should be subtle" (or vice versa)
**Check:**
- Exaggeration - Calibrated to style?
- Squash/stretch - Amount appropriate?
- Timing - Snappy vs. naturalistic?
- Anticipation - Size matches style?

**Fix:** Dial exaggeration to match reference. Adjust squash/stretch ratios. Match timing to style guide.

### "Something feels wrong but I can't identify it"
**Check:**
- Arcs - Track every moving part. Find the broken curve.
- Volume - Is squash/stretch preserving mass?
- Twins - Are poses too symmetrical?
- Spacing - Graph your drawings. Find the anomaly.

**Fix:** Often it's one broken arc or inconsistent spacing. Track paths obsessively.

## Principle Conflict Symptoms

**Anticipation vs. Surprise:** Big anticipation kills surprise. Choose intentionally.

**Exaggeration vs. Subtlety:** Can't have both. What does the scene need?

**Follow through vs. Snappiness:** Heavy follow through softens snappy timing. Balance.

**Secondary vs. Primary:** If secondary distracts, remove it regardless of quality.

## Last Resort Fixes

1. Return to blocking. Is the idea clear at the key pose level?
2. Remove all overlap/secondary. Does primary action work alone?
