What this skill does


# Universal Element Animation Principles

Apply Disney's 12 principles to any UI element for consistent, professional motion design.

## Universal Application of Principles

### 1. Squash & Stretch
Any element that responds to interaction can squash (compress on impact/press) and stretch (extend on release). Keep it subtle: 2-5% maximum for UI.

### 2. Anticipation
Before any significant action, a brief preparatory motion signals what's coming. Scale down before scale up, pull back before push forward. 50-100ms duration.

### 3. Staging
Direct attention to the most important element. Use contrast in motion, size, color, z-index, and blur to create clear visual hierarchy.

### 4. Straight Ahead & Pose to Pose
Pose-to-pose for most UI: define start and end states clearly. Straight-ahead for organic, flowing animations like particles or organic shapes.

### 5. Follow Through & Overlapping Action
Nothing stops all at once. Child elements lag behind parents. Shadows settle after objects. Stagger related elements 20-50ms apart.

### 6. Ease In & Ease Out
The golden rule: never use `linear` for UI motion. Enter with `ease-out`, exit with `ease-in`, transition with `ease-in-out`.

### 7. Arcs
Natural motion follows curved paths. Add subtle vertical movement to horizontal transitions. Rotate while translating. Avoid robotic straight lines.

### 8. Secondary Action
Every primary action deserves supporting animation. Shadow changes, color shifts, icon rotations, glow effects reinforce without competing.

### 9. Timing
| Element Type | Fast | Normal | Slow |
|--------------|------|--------|------|
| Micro (icons, buttons) | 50-100ms | 100-200ms | 200-300ms |
| Small (cards, inputs) | 150-200ms | 200-300ms | 300-400ms |
| Medium (modals, menus) | 200-250ms | 250-350ms | 350-500ms |
| Large (pages, overlays) | 300-400ms | 400-600ms | 600-800ms |

### 10. Exaggeration
Match animation intensity to context. Celebratory moments allow 20-30% exaggeration. Professional contexts keep it under 10%. Error states can be more dramatic.

### 11. Solid Drawing
Maintain visual consistency: border-radius ratios, shadow directions, spacing rhythms, typography scale. Nothing should distort or break during animation.

### 12. Appeal
The goal is delight without distraction. Smooth animations build trust. Snappy feedback feels responsive. The best animation is felt, not noticed.

## CSS Foundation

```css
/* Universal transition base */
* {
  transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);
}

/* Standard durations as custom properties */
:root {
  --duration-fast: 100ms;
  --duration-normal: 200ms;
  --duration-slow: 350ms;
  --ease-out: cubic-bezier(0.0, 0, 0.2, 1);
  --ease-in: cubic-bezier(0.4, 0, 1, 1);
  --ease-standard: cubic-bezier(0.4, 0, 0.2, 1);
  --ease-bounce: cubic-bezier(0.68, -0.55, 0.27, 1.55);
}

/* Apply to any interactive element */
.interactive {
  transition: transform var(--duration-normal) var(--ease-standard),
              opacity var(--duration-normal) var(--ease-standard),
              box-shadow var(--duration-normal) var(--ease-standard);
}
```

## Key Properties (Any Element)
- `transform`: universal positioning and scaling
- `opacity`: visibility transitions
- `transition`: state changes
- `animation`: complex sequences
- `box-shadow`: depth and emphasis

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config.

react-native-skia

Included

Design, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.

nextjs-framer-motion-animations

Included

Adds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
