# interaction-design

A skill for designing interface feedback: loading states, errors, empty screens, animation timing and accessibility. Useful when you need to plan how UI behaves, not just how it looks.

## What it does

The skill sets rules for interaction: how long a microinteraction, a transition or a list entrance should run, how to show a wait, and what to do when a request fails. It ships a duration table, a CSS skeleton loader, JSX components for error and empty states, and an accessibility section covering `aria-live` and `prefers-reduced-motion`.

Animations should stay under 500ms, with ease-out for entering and ease-in for exiting. Focus indicators must stay visible, and keyboard navigation needs testing. Those are the spots where interfaces usually break for keyboard users or anyone with reduced motion turned on.

Install with `npx skills add secondsky/claude-skills --skill interaction-design -a claude-code`; the file lands at `~/.claude/skills/interaction-design/SKILL.md`. Codex, Cursor, Gemini CLI and OpenCode have their own install commands, and GitHub Copilot uses `gh skill install`. MIT licensed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --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 secondsky/claude-skills --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 secondsky/claude-skills --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 secondsky/claude-skills 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 secondsky/claude-skills --skill interaction-design -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/interaction-design/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 secondsky/claude-skills --skill interaction-design -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/secondsky/claude-skills/tree/HEAD/plugins/interaction-design/skills/interaction-design/SKILL.md

## When to use it
- design loading states for slow requests
- write an error screen with a retry button
- make an empty list look intentional instead of broken
- pick animation durations for a modal and a list entrance
- announce state changes to screen readers

## Example prompts
- Design loading and error states for an orders list page
- Pick animation durations for the modal and the card entrance
- Check that the error screen works with keyboard navigation and screen readers

# Interaction Design

Create intuitive user experiences through thoughtful feedback and interaction patterns.

## Interaction Patterns

| Pattern | Duration | Use Case |
|---------|----------|----------|
| Microinteraction | 100-200ms | Button press, toggle |
| Transition | 200-400ms | Page change, modal |
| Entrance | 300-500ms | List items appearing |

## Loading States

```css
/* Skeleton loader */
.skeleton {
  background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
  background-size: 200% 100%;
  animation: shimmer 1.5s infinite;
}

@keyframes shimmer {
  0% { background-position: 200% 0; }
  100% { background-position: -200% 0; }
}
```

```jsx
function LoadingState({ isLoading, children }) {
  if (isLoading) {
    return <div className="skeleton" style={{ height: 200 }} />;
  }
  return children;
}
```

## Error States

```jsx
function ErrorState({ error, onRetry }) {
  return (
    <div className="error-container" role="alert">
      <Icon name="warning" />
      <h3>Something went wrong</h3>
      <p>{error.message}</p>
      <button onClick={onRetry}>Try Again</button>
    </div>
  );
}
```

## Empty States

```jsx
function EmptyState({ title, description, action }) {
  return (
    <div className="empty-state">
      <Illustration name="empty-inbox" />
      <h3>{title}</h3>
      <p>{description}</p>
      {action && <button onClick={action.onClick}>{action.label}</button>}
    </div>
  );
}
```

## Accessibility

```jsx
// Announce state changes to screen readers
function StatusAnnouncer({ message }) {
  return (
    <div aria-live="polite" aria-atomic="true" className="sr-only">
      {message}
    </div>
  );
}

// Respect motion preferences
const prefersReducedMotion = window.matchMedia('(prefers-reduced-motion: reduce)').matches;
```

## Animation Guidelines

- Keep animations under 500ms (longer feels sluggish)
- Use ease-out for entering, ease-in for exiting
- Respect `prefers-reduced-motion`
- Ensure focus indicators are always visible
- Test with keyboard navigation

## Best Practices

- Provide immediate feedback for all actions
- Show loading states for waits >0.5s
- Include clear error messages with recovery options
- Design meaningful empty states
- Support keyboard navigation
