## What it does

The command inspects `.ui-design/`, custom themes in `tailwind.config.js`, CSS variables, token files such as `tokens.json` or `theme.ts`, and packages including `chakra`, `radix`, and `shadcn`. It also reads `conductor/tech-stack.md` when present and checks the project’s styling approach and TypeScript use.

It then collects choices one at a time: preset, brand colors, color modes, font, spacing scale, corner radius, and output format. The comprehensive preset can include guidance for buttons, forms, cards, typography, and icons.

Progress is written to `.ui-design/setup_state.json`; generated values cover colors, typography, spacing, and related tokens. When `.ui-design/design-system.json` already exists, the command asks whether to integrate, replace, inspect, or cancel instead of proceeding silently.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install ui-design@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/commands/design-system-setup.md` — Call it with /design-system-setup. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/design-system-setup.md` — Call it with /prompts:design-system-setup. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/design-system-setup.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/design-system-setup.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/ui-design/commands/design-system-setup.md

## When to use it
- define color and typography tokens
- choose an output format for design tokens
- fit a new system around Tailwind or CSS
- save the setup choices between steps
- draft rules for common UI components

## Example prompts
- Run `/ui-design:design-system-setup` and configure a standard design system.
- Start the command with `--preset minimal` for a smaller token set.
- Inspect the current UI setup and suggest how to integrate missing tokens.

# Design System Setup

Initialize a design system with design tokens, component patterns, and documentation. Creates a foundation for consistent UI development.

## Pre-flight Checks

1. Check if `.ui-design/` directory exists:
   - If exists with `design-system.json`: Ask to update or reinitialize
   - If not: Create `.ui-design/` directory

2. Detect existing design system indicators:
   - Check for `tailwind.config.js` with custom theme
   - Check for CSS custom properties in global styles
   - Check for existing token files (tokens.json, theme.ts, etc.)
   - Check for design system packages (chakra, radix, shadcn, etc.)

3. Load project context:
   - Read `conductor/tech-stack.md` if exists
   - Detect styling approach (CSS, Tailwind, styled-components, etc.)
   - Detect TypeScript usage

4. If existing design system detected:

   ```
   I detected an existing design system configuration:

   - {detected_system}

   Would you like to:
   1. Integrate with existing system (add missing tokens)
   2. Replace with new design system
   3. View current configuration
   4. Cancel

   Enter number:
   ```

## Interactive Configuration

**CRITICAL RULES:**

- Ask ONE question per turn
- Wait for user response before proceeding
- Build complete specification before generating files

### Q1: Design System Preset (if not provided)

```
What level of design system do you need?

1. Minimal   - Colors, typography, spacing only
               Best for: Small projects, rapid prototyping

2. Standard  - Colors, typography, spacing, shadows, borders, breakpoints
               Best for: Most projects, good balance of flexibility

3. Comprehensive - Full token system with semantic naming, component tokens,
                   animation, and documentation
               Best for: Large projects, design teams, long-term maintenance

Enter number:
```

### Q2: Brand Colors

```
Let's define your brand colors.

Enter your primary brand color (hex code, e.g., #3B82F6):
```

After receiving primary:

```
Primary color: {color}

Now enter your secondary/accent color (or press enter to auto-generate):
```

### Q3: Color Mode Support

```
What color modes should the design system support?

1. Light mode only
2. Dark mode only
3. Light and dark modes
4. Light, dark, and system preference

Enter number:
```

### Q4: Typography

```
What font family should be used?

1. System fonts (fastest loading, native feel)
   font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', ...

2. Inter (modern, highly readable)
3. Open Sans (friendly, versatile)
4. Roboto (clean, Google standard)
5. Custom (provide name)

Enter number or font name:
```

### Q5: Spacing Scale

```
What spacing scale philosophy?

1. Linear (4px base)
   4, 8, 12, 16, 20, 24, 32, 40, 48, 64

2. Geometric (4px base, 1.5x multiplier)
   4, 6, 9, 14, 21, 32, 48, 72

3. Tailwind-compatible
   0, 1, 2, 4, 6, 8, 12, 16, 20, 24, 32, 40, 48, 64

4. Custom (provide values)

Enter number:
```

### Q6: Border Radius

```
What corner radius style?

1. Sharp    - 0px (no rounding)
2. Subtle   - 4px (slight rounding)
3. Moderate - 8px (noticeable rounding)
4. Rounded  - 12px (significant rounding)
5. Pill     - 9999px for buttons, 16px for cards

Enter number:
```

### Q7: Output Format

```
How should the design tokens be output?

1. CSS Custom Properties (works everywhere)
2. Tailwind config (tailwind.config.js extension)
3. JavaScript/TypeScript module
4. JSON tokens (Design Token Community Group format)
5. Multiple formats (all of the above)

Enter number:
```

### Q8: Component Guidelines (Comprehensive only)

If comprehensive preset selected:

```
