# design-system-creation

A skill that walks the agent through building a design system: tokens, typography, components and their docs. Useful when UI standards need to be settled before code.

## What it does

The skill splits a design system into three layers: foundation (colors, typography, spacing, elevation), components (buttons, inputs, cards, navigation) and patterns (forms, layouts, empty states). The agent follows that order, so tokens come out before components do.

The foundation is written as CSS variables in `:root`: a color scale from `--color-primary-50` to `--color-primary-900`, semantic `--color-success`, `--color-warning`, `--color-error`, the `--font-sans` and `--font-mono` stacks, text sizes from `--text-xs` to `--text-2xl`, spacing on a 4px base and three shadow levels. Every component gets documented by anatomy, variants, states and accessibility, and the React button example carries `variant`, `size`, `loading` and `aria-busy` props.

Governance is its own section: a review committee approves new components, contributions move through RFC → review → implementation, releases follow semantic versioning, and deprecation means a 3-month notice plus a migration guide. If your project already has a token set, the skill will happily propose a second scale on top of it, so decide which one stays canonical first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill design-system-creation -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill design-system-creation -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill design-system-creation -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install secondsky/claude-skills design-system-creation
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/design-system-creation/skills/design-system-creation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill design-system-creation -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/design-system-creation/skills/design-system-creation/SKILL.md

## When to use it
- lock colors, fonts and spacing into tokens before layout work starts
- build a button, input and card library that behaves the same everywhere
- document a component's variants and states for the next developer
- ship dark mode and semantic colors from the first commit
- move a new component through review and versioning

## Example prompts
- build a design system for a new project: tokens, typography, spacing and shadows
- document the Button component: anatomy, variants, states, accessibility
- add semantic colors and dark mode support to the design system

# Design System Creation

Build comprehensive design systems for consistent UI development across teams.

## Design System Layers

1. **Foundation**: Colors, typography, spacing, elevation
2. **Components**: Buttons, inputs, cards, navigation
3. **Patterns**: Forms, layouts, empty states

## Foundation - Design Tokens

```css
:root {
  /* Colors */
  --color-primary-50: #eff6ff;
  --color-primary-500: #3b82f6;
  --color-primary-900: #1e3a8a;

  /* Semantic colors */
  --color-success: #22c55e;
  --color-warning: #f59e0b;
  --color-error: #ef4444;

  /* Typography */
  --font-sans: 'Inter', system-ui, sans-serif;
  --font-mono: 'Fira Code', monospace;

  /* Type scale */
  --text-xs: 0.75rem;
  --text-sm: 0.875rem;
  --text-base: 1rem;
  --text-lg: 1.125rem;
  --text-xl: 1.25rem;
  --text-2xl: 1.5rem;

  /* Spacing (4px base) */
  --space-1: 0.25rem;
  --space-2: 0.5rem;
  --space-4: 1rem;
  --space-8: 2rem;

  /* Elevation */
  --shadow-sm: 0 1px 2px rgba(0,0,0,0.05);
  --shadow-md: 0 4px 6px rgba(0,0,0,0.1);
  --shadow-lg: 0 10px 15px rgba(0,0,0,0.1);
}
```
