# mobile-touch

A skill that steers your coding agent through gesture, haptic and animation work on iOS and Android. Useful when you need motion that feels native instead of guessed.

## What it does

The skill maps Disney's 12 animation principles onto mobile scenarios. Each principle gets a concrete implementation: rubber-banding at scroll boundaries, long-press previews, momentum scrolling after the finger lifts, spring transitions on iOS and Material easing on Android.

Inside you get a reference table, a timing section and haptic guidelines. The timings are explicit: touch acknowledgment under 100ms, quick actions 150–250ms, view transitions 250–350ms, complex animations 350–500ms. Haptics come with a mapping table — selection, success, warning and error each get their own feedback style on iOS and Android. Swift and Kotlin snippets are included.

One rule the skill repeats: haptics are a secondary action, so pair them with visual confirmation. It also advises against linear easing for user-initiated motion. If you are building web or desktop UI, this material will not help — it is entirely about native mobile platforms.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/01-by-domain/mobile-touch
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

### Claude.ai

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

## When to use it
- pick a touch response timing
- sync haptic feedback with the visual reaction
- build a spring transition between iOS screens
- tune momentum scrolling after the finger lifts
- choose an easing curve for a gesture-driven animation

## Example prompts
- Set up a spring animation for a card on iOS
- What timings should I use for a screen transition?
- Pick a haptic response for confirming an action

# Mobile Touch Animation

Apply Disney's 12 animation principles to mobile gestures, haptics, and native app motion.

## Quick Reference

| Principle | Mobile Implementation |
|-----------|----------------------|
| Squash & Stretch | Rubber-banding, bounce on scroll limits |
| Anticipation | Peek before reveal, long-press preview |
| Staging | Sheet presentations, focus states |
| Straight Ahead / Pose to Pose | Gesture-driven vs preset transitions |
| Follow Through / Overlapping | Momentum scrolling, trailing elements |
| Slow In / Slow Out | iOS spring animations, Material easing |
| Arc | Swipe-to-dismiss curves, card throws |
| Secondary Action | Haptic pulse with visual feedback |
| Timing | Touch response <100ms, transitions 250-350ms |
| Exaggeration | Bounce amplitude, haptic intensity |
| Solid Drawing | Respect safe areas, consistent anchors |
| Appeal | 60fps minimum, gesture continuity |

## Principle Applications

**Squash & Stretch**: Implement rubber-band effect at scroll boundaries. Pull-to-refresh should stretch content naturally. Buttons compress on touch.

**Anticipation**: Long-press shows preview before full action. Drag threshold provides visual hint before item lifts. Swipe shows edge of destination content.

**Staging**: Use sheet presentations to maintain context. Dim and scale background during modal focus. Hero transitions connect views meaningfully.

**Straight Ahead vs Pose to Pose**: Gesture-following animations (drag, pinch) are straight ahead—driven by touch input. System transitions (push, present) are pose to pose—predefined keyframes.

**Follow Through & Overlapping**: Content continues moving after finger lifts (momentum). Navigation bar elements animate slightly after main content. Lists items settle with stagger.

**Slow In / Slow Out**: iOS uses spring physics—configure mass, stiffness, damping. Android Material uses standard easing: `FastOutSlowIn`. Never use linear for user-initiated motion.

**Arc**: Thrown cards follow parabolic arcs. Swipe-to-dismiss curves based on velocity vector. FAB expand/collapse follows natural arc path.

**Secondary Action**: Pair haptic feedback with visual response. Button ripple accompanies press. Success checkmark triggers light haptic.

**Timing**: Touch acknowledgment: <100ms. Quick actions: 150-250ms. View transitions: 250-350ms. Complex animations: 350-500ms. Haptic should sync precisely with visual.

**Exaggeration**: Pull-to-refresh stretches beyond natural—makes feedback clear. Error shake is pronounced. Success animations celebrate appropriately.
