# Greyhaven Design System
|
|
|
|
A framework-agnostic React component library built on Radix UI, Tailwind CSS v4, and shadcn/ui patterns. Designed for LLM consumption with a Claude Skill, MCP server, and Storybook documentation.
|
|
|
|
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
pnpm install # Install dependencies
|
|
pnpm dev # Start showcase dev server (Next.js)
|
|
pnpm build # Tokens + SKILL.md + production build
|
|
pnpm storybook # Component catalog on http://localhost:6006
|
|
```
|
|
|
|

|
## Tech Stack
|
|
|
|
- **Components**: React 19, Radix UI, Tailwind CSS 4, CVA, tailwind-merge, clsx
|
|
- **Icons**: Lucide React
|
|
- **Forms**: React Hook Form + Zod
|
|
- **Tokens**: Style Dictionary v4 (W3C DTCG format)
|
|
- **Docs**: Storybook 10, auto-generated SKILL.md
|
|
- **AI Integration**: MCP server, Claude Skill
|
|
|
|
> **Framework-agnostic**: Components have zero Next.js imports. They work with Vite, Remix, Astro, CRA, or any React framework.

## Using the Design System with AI
|
|
|
|
The design system provides two complementary ways for AI agents to consume it:
|
|
|
|
| | Claude Skill (SKILL.md) | MCP Server |
|
|
|---|---|---|
|
|
| **What it is** | A single markdown file with all tokens, components, and rules | A running process that reads source files in real-time |
|
|
| **Stays in sync** | Yes -- auto-generated from the same token files and component catalog | Yes -- reads source at runtime |
|
|
| **Setup** | Copy/symlink one file | Start a server process |
|
|
| **Best for** | Claude Code sessions, quick context | Programmatic access, validation, any MCP-compatible agent |
|
|
|
|
Both read from the same sources (`tokens/*.json` and `lib/catalog.ts`), so they always agree.
|
|
|
|
### Option A: Claude Skill (SKILL.md)
|
|
|
|
The skill file gives any Claude Code session full design system context -- tokens, all components with props/examples, composition rules, and the extension protocol.
|
|
|
|
**Install into a consuming project:**
|
|
|
|
```bash
|
|
# From the design system repo
|
|
./skill/install.sh /path/to/your/project
|
|
|
|
# Or manually
|
|
mkdir -p /path/to/your/project/.claude/skills
|
|
ln -sf /absolute/path/to/greyhaven-design-system/skill/SKILL.md \
|
|
/path/to/your/project/.claude/skills/greyhaven.md
|
|
```
|
|
|
|
**Regenerate after changes:**
|
|
|
|
```bash
|
|
pnpm skill:build
|
|
```
|
|
|
|
This is run automatically as part of `pnpm build`. If you add a component, add it to `lib/catalog.ts` and regenerate.
|
|
|
|
### Option B: MCP Server
|
|
|
|
The MCP server provides 5 tools for programmatic access:
|
|
|
|
| Tool | Description |
|
|
|------|-------------|
|
|
| `get_tokens(category?)` | Returns token values (all, or filtered by: color, typography, spacing, radii, shadows, motion) |
|
|
| `get_component(name)` | Returns full component spec + source code |
|
|
| `list_components(category?)` | Lists components (all, or by: primitives, layout, overlay, navigation, data, feedback, form, composition) |
|
|
| `validate_colors(code)` | Checks code for raw hex values that should use design tokens |
|
|
| `suggest_component(description)` | Suggests components for a described UI need |
|
|
|
|
Plus resources: `tokens://all` and `component://{name}` for each component.
|
|
|
|
**Run directly:**
|
|
|
|
```bash
|
|
pnpm mcp:start
|
|
```
|
|
|
|
**Install in Claude Code (`~/.claude/settings.json`):**
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"greyhaven": {
|
|
"command": "npx",
|
|
"args": ["tsx", "/absolute/path/to/greyhaven-design-system/mcp/server.ts"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Install in Claude Desktop (`claude_desktop_config.json`):**
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"greyhaven": {
|
|
"command": "npx",
|
|
"args": ["tsx", "/absolute/path/to/greyhaven-design-system/mcp/server.ts"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
After adding, restart Claude Code / Claude Desktop. The tools will appear automatically.
|
|
|
|
**Test it works:**
|
|
|
|
```bash
|
|
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' | pnpm mcp:start
|
|
```
|
|
|
|
You should see a JSON response with `"serverInfo":{"name":"greyhaven-design-system"}`.
|
|
|

## Design Tokens
|
|
|
|
Tokens are defined in `tokens/*.json` using the [W3C Design Token Community Group](https://tr.designtokens.org/format/) format. Style Dictionary v4 generates:
|
|
|
|
| Output | Path | Purpose |
|
|
|--------|------|---------|
|
|
| CSS (light) | `app/tokens/tokens-light.css` | `:root` CSS custom properties |
|
|
| CSS (dark) | `app/tokens/tokens-dark.css` | `.dark` CSS custom properties |
|
|
| TypeScript | `app/tokens/tokens.ts` | Type-safe token constants |
|
|
| Markdown | `app/tokens/TOKENS.md` | Reference doc |
|
|
|
|
```bash
|
|
pnpm tokens:build # Regenerate all outputs from tokens/*.json
|
|
```
|
|
|
|
---
|
|
|
|
## Storybook
|
|
|
|
23 story files across 8 categories with autodocs, theme switching (light/dark via toolbar), and all component variants.
|
|
|
|
```bash
|
|
pnpm storybook # Dev server on http://localhost:6006
|
|
pnpm build-storybook # Static build
|
|
```
|
|
|
|
---
|
|
|
|
## Adding a New Component
|
|
|
|
1. Create `components/ui/my-component.tsx` following the CVA pattern (see `button.tsx`)
|
|
2. Add it to the catalog in `lib/catalog.ts`
|
|
3. Create a story in `stories/<Category>/MyComponent.stories.tsx`
|
|
4. Run `pnpm skill:build` to regenerate SKILL.md (or just `pnpm build`)
|
|
5. The MCP server picks it up automatically (reads `lib/catalog.ts` at runtime)
|
