A ready-to-use Claude Code environment for website design, bundling: - .mcp.json: Playwright + Chrome DevTools + shadcn MCP servers - CLAUDE.md: the design loop (plan -> commit to a look -> build -> screenshot -> review) - .claude/agents/design-review.md: 7-phase design-review subagent (WCAG AA, responsive) - .claude/commands: /design-review, /design-plan - scripts/design-audit.mjs: standalone multi-viewport screenshot + heuristic audit - .github/workflows/design-review.yml: CI design gate (template) - docs/: STACK, SETUP, WORKFLOW - examples/juniper-audit/: a real audit run (report + 6 viewport screenshots) Pairs with the ui-ux-pro-max skill (knowledge layer) and the official frontend-design plugin (taste layer). Lives on its own branch as a self-contained starter; copy stack/ out to seed a standalone repo. Co-authored-by: Claude <noreply@anthropic.com>
Claude Website Design Stack
A ready-to-clone Claude Code project that makes the agent genuinely good at website design — not by hoping for better output, but by wiring in the three things generic AI design is missing: a knowledge layer, a taste layer, and a visual feedback layer.
Most AI design fails because the model never sees what it built and has no opinionated point of view. This repo fixes both: Claude plans with a real design database, commits to a distinctive aesthetic, then opens the page in a browser and iterates on what it sees — and self-reviews against WCAG AA before finishing.
The stack
| Layer | Tool | What it adds |
|---|---|---|
| 🧠 Knowledge | ui-ux-pro-max |
84 UI styles, 192 color palettes, 73 font pairings, 99 UX rules, Core Web Vitals, 22 stacks — searchable, turned into a concrete design system |
| 🎨 Taste | frontend-design (official Anthropic) |
Forces a real aesthetic commitment before any CSS; kills "AI slop" defaults |
| 🧩 Components | shadcn MCP |
Search/add production components by natural language |
| 👁️ Visual feedback | @playwright/mcp + chrome-devtools-mcp |
Claude opens a real browser, screenshots, reads the console, exercises states, and fixes what it sees |
| ✅ Automated review | design-review subagent + /design-review |
7-phase audit across viewports: WCAG AA, responsive, interaction states |
Quickstart
# 1. Clone and enter
git clone https://github.com/YMungerDev/claude-website-design-stack
cd claude-website-design-stack
# 2. Install the skills/plugins + Playwright browser
./scripts/setup.sh
# 3. Open Claude Code — the MCP servers and CLAUDE.md workflow load automatically
claude
Then just ask for UI work. Claude will plan → commit to a look → build → screenshot and
iterate → run /design-review. See docs/WORKFLOW.md for a full walkthrough.
Try it in 30 seconds
> Build a pricing section for a developer tool. Plan it with ui-ux-pro-max,
> commit to a distinctive look, then screenshot it at mobile and desktop and fix any issues.

Standalone audit (no MCP needed)
The same checks are available as a plain script for local runs and CI:
node scripts/design-audit.mjs --url http://localhost:3000 --out audit-output
# or audit a static file
node scripts/design-audit.mjs --file ./index.html
It screenshots 7 viewport tiers (360 → 1920 px) and reports heuristic findings
(horizontal overflow, missing focus styles, unsized media, contrast risks, tap-target size).
See examples/juniper-audit/ for a real report.
Requirements
- Node 18+ and Python 3.x
- Claude Code with plugins enabled (
