It connects squash and stretch with how people read motion, anticipation with prediction, and staging with limited focal attention. Follow through, arcs, and slow in/out are framed through physical consistency and the viewer’s sense that movement belongs to a rule-bound world. It also contrasts pose-to-pose, where intent and choices are planned, with straight ahead, where behavior emerges during the process. Timing is treated as felt time shaped by emotion. Exaggeration fills in for context that animation cannot provide, while appeal draws on attention to faces, movement, contrast, and patterns. The principles are brought together under one idea: believable change over time. This is a reasoning guide rather than a checklist, so its value depends on engaging with perception and storytelling instead of memorizing isolated rules. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add dylantarre/animation-principles --skill animation-principles---master -a claude-code ``` ```bash npx skills add dylantarre/animation-principles --skill master -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/master/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/master/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add dylantarre/animation-principles --skill master -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/master/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add dylantarre/animation-principles --skill master -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/master/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install dylantarre/animation-principles master ``` 2. **Manually: put the files in place** - File: `.github/skills/master/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add dylantarre/animation-principles --skill master -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/dylantarre/animation-principles --path skills/04-by-skill-level/master ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/master/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add dylantarre/animation-principles --skill master -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/master/SKILL.md ## When to use it - explain why animation principles work - connect squash and stretch to motion perception - compare pose-to-pose with straight ahead - analyze how timing changes emotional impact - teach the principles through visual psychology ## Example prompts - Explain the philosophical basis of animation principles through human perception and storytelling. - Compare pose-to-pose and straight ahead as two working philosophies. - Analyze why staging and anticipation make an action easier to read. ## Source text · SKILL.md · MIT Below is the content of a third-party file.

This is animation as visual psychology. ## Why the Principles Work ### Squash and Stretch: Persistence of Vision The eye blurs motion. Stretch simulates motion blur our brains expect. Squash simulates impact compression we've observed since infancy. We're matching internal neural predictions. ### Anticipation: Predictive Processing Human brains constantly predict next moments. Anticipation feeds this system information, making action legible. Without it, perception lags behind action. ### Staging: Attentional Bandwidth Humans have limited focal attention. Staging respects cognitive constraints. It's not artistic preference - it's information architecture for biological processors. ### Method Philosophy Pose-to-pose: Animation as acting - clear intentions, deliberate choices. Straight ahead: Animation as discovery - emergent behavior, organic evolution. Both philosophies are valid worldviews. ### Follow Through: Physics as Metaphor Objects with follow through feel like they exist in a world with rules. Rules create believability. Even cartoon physics must be internally consistent. ### Slow In/Out: Natural Motion Universals Almost nothing in nature moves at constant velocity. Ease reflects universal physics. It's not stylistic - it's the visual signature of mass and energy. ### Arcs: Gravitational Truth Pendulums, projectiles, limbs - rotation and gravity create curves. Arcs are motion's natural signature. Linear paths require explanation. ### Secondary Action: Cognitive Depth Humans assess situations through multiple channels simultaneously. Secondary action mimics this richness. Single-channel communication feels impoverished. ### Timing: Emotional Chronometry We feel time differently based on emotional state. Animation timing recreates these subjective time distortions. Fast isn't always fast - it's how fast *feels*. ### Exaggeration: Perceptual Compensation Animation lacks the subconscious information of reality - smell, peripheral vision, lived context. Exaggeration compensates for this perceptual deficit. ### Solid Drawing: Haptic Memory We've touched things our whole lives. Solid drawing activates this tactile memory. Flat drawings exist only visually; solid drawings exist in imagined space. ### Appeal: Evolved Attention ``` END THIRD-PARTY FILE 0f81d25d57ee70e5 The third-party file has ended.
