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>

Setup
Prerequisites
- Node 18+ and Python 3.x
- Claude Code with plugins enabled (run
/pluginonce to enable)
1. One-shot setup
./scripts/setup.sh
This installs the audit dependencies (Playwright + Chromium) and the ui-ux-pro-max skill,
then prints the two steps that must happen inside Claude Code.
2. Install the taste plugin (inside Claude Code)
/plugin install frontend-design@anthropics/claude-code
3. Approve the MCP servers
Open Claude Code in this directory. It reads .mcp.json and prompts you to approve the project
MCP servers (playwright, chrome-devtools, shadcn). Approve them. .claude/settings.json
already sets enableAllProjectMcpServers: true, so they load on start. Verify with /mcp.
That's it — CLAUDE.md defines the design loop and loads automatically.
Verify it works
> /design-plan portfolio site for a photographer, editorial and minimal
> Build the hero, then screenshot it at 375px and 1440px and fix anything that breaks.
> /design-review http://localhost:3000
You should see Claude pull tokens from ui-ux-pro-max, open a browser, screenshot, and return
ranked findings.
Standalone audit (no Claude needed)
npm run audit -- --url http://localhost:3000
npm run audit -- --file ./index.html
Outputs audit-output/report.md + per-viewport screenshots. Exit code is non-zero when there
are high-severity findings (useful for CI — see .github/workflows/design-review.yml).
Optional add-ons
Figma Dev Mode MCP
Requires the Figma desktop app. Enable Dev Mode → toggle the MCP server on. Then add to
.mcp.json:
"figma": { "url": "http://127.0.0.1:3845/mcp" }
Guide: https://help.figma.com/hc/en-us/articles/39888612464151-Claude-Code-and-Figma-Set-up-the-MCP-server
21st.dev Magic MCP
Generates React components from a prompt. Get an API key at https://21st.dev, then add:
"magic": { "command": "npx", "args": ["-y", "@21st-dev/magic@latest"], "env": { "API_KEY": "<your-key>" } }
Keep keys out of git — prefer .claude/settings.local.json or your shell env, both gitignored.
Troubleshooting
/mcpshows a server failed — run its command manually to see the error, e.g.npx -y @playwright/mcp@latest. Usually a Node version or network/proxy issue.- Audit can't find Chromium — run
npx playwright install chromium, or setPW_EXECUTABLE_PATHto your Chromium binary. - ui-ux-pro-max command not found — re-run
npx ui-ux-pro-max-cli init --ai claudeand check the printed skill path; use that path in thepython3 …/search.pycommands.
