# interaction-design

A skill for designing interactions: animations, loading and error states, feedback on touch. Useful when the interface works but feels flat.

## What it does

The skill gives the agent a frame for interaction design: gestures, transitions, feedback after an action. It ships reference guides in the `references/` directory covering animation and transition design, error handling and feedback, and accessibility in interactions. Alongside them sits a practice list: keep animations under 400ms, make interactions reversible, provide keyboard and screen reader alternatives.

The quick start covers common gestures — swipe, tap and hold, pinch and zoom, drag and drop, double tap. Each entry names where it fits, what feedback to give, and what to offer people who cannot use the gesture. It suggests starting a hold around 500ms before the trigger fires.

One limit is worth knowing up front: the skill designs, it does not test. Without keyboard and screen reader tests in your project, the accessibility advice stays on paper. That is a reason to check whether such tests exist before letting the agent rewrite your transitions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill interaction-design -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill interaction-design -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill interaction-design -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts interaction-design
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill interaction-design -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/interaction-design
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill interaction-design -a opencode
```

### Claude.ai

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

## When to use it
- design loading and error states for a checkout form
- pick duration and easing for a screen transition
- add a keyboard alternative to a swipe gesture
- describe drag-and-drop behaviour for reorderable cards
- check whether an animation breaks users sensitive to motion

## Example prompts
- Design microinteractions for a product card: tap, hold, add to favourites
- Walk through loading and error states for the payment form using the interaction-design guide
- Review my screen transitions: durations, easing, keyboard alternatives

## Overview

Interaction design focuses on how users engage with systems, creating intuitive and delightful experiences through feedback and responsiveness.

## When to Use

- Designing user flows and touchpoints
- Creating animations and transitions
- Defining error and loading states
- Building microinteractions
- Improving usability and feedback
- Mobile interaction patterns

## Quick Start

Minimal working example:

```yaml
Common Interaction Patterns:

Swipe:
  Use: Mobile lists, carousels
  Feedback: Visual sliding, momentum
  Accessibility: Keyboard alternative (arrows)

Tap & Hold:
  Use: Context menus, drag prep
  Feedback: Visual feedback after delay
  Duration: ~500ms before trigger

Pinch & Zoom:
  Use: Image viewing, maps
  Feedback: Smooth zoom animation
  Boundaries: Set min/max zoom levels

Drag & Drop:
  Use: Reordering, moving items
  Feedback: Visual during drag, drop confirmation
  Fallback: Alternative method (buttons)

Double Tap:
  Use: Zoom, favorite, select
  Feedback: Immediate visual response
// ... (see reference guides for full implementation)
```

## Reference Guides

Detailed implementations in the `references/` directory:

| Guide | Contents |
|---|---|
| [Animation & Transition Design](references/animation-transition-design.md) | Animation & Transition Design |
| [Error Handling & Feedback](references/error-handling-feedback.md) | Error Handling & Feedback |
| [Accessibility in Interactions](references/accessibility-in-interactions.md) | Accessibility in Interactions |

## Best Practices

### ✅ DO

- Keep animations under 400ms
- Provide clear visual feedback
- Use animations to guide attention
- Respect motion preferences
- Make interactions reversible
- Test with keyboard and screen readers
- Provide multiple interaction methods
- Design for touch and mouse
- Use appropriate easing curves
- Document interaction behavior

### ❌ DON'T

- Animate for decoration only
- Use animations longer than 500ms
- Ignore motion-sensitive users
- Remove focus indicators
- Trap users in modals
- Use confusing animations
- Animate everything
- Ignore loading states
- Forget error states
- Skip accessibility testing
