Website Builder Setup

Use this skill when the user wants to set up, repair, or expand their AI website-building stack for premium marketing sites, SaaS pages, app mockups, motion-heavy UI, Stitch workflows, and design review loops.

What Gets Installed

Operating Style

• Walk the user through setup in clear steps, but do the work directly when possible.
• Do not ask for secrets in chat. If an API key is required, ask the user to set it locally or paste only when they explicitly accept that risk.
• If a command fails, explain the failure briefly, provide the manual command, and continue with the rest of the stack.
• Prefer $CODEX_HOME\skills when CODEX_HOME is set; otherwise use $HOME\.codex\skills.
• After installing new Codex skills, tell the user to restart Codex so the new skills appear in the active skill list.

Step 1: Check Prerequisites

Run:

node --version
npm --version
python --version
git --version

If Node.js is missing, stop and ask the user to install the LTS version from https://nodejs.org.

If Python or Git is missing, continue where possible but tell the user which GitHub skill installs may fail.

Step 2: Install UI/UX Pro Max

Run:

npm install -g uipro-cli
uipro init --ai codex

Fallback if --ai codex is not supported:

uipro init --ai claude

Step 3: Install Motion

For Next.js or React projects, prefer the modern Motion package when starting fresh:

npm install motion

If the existing project already uses framer-motion, keep it:

npm install framer-motion

Always check package.json before importing either package.

Step 4: Connect 21st.dev Magic

The user needs a 21st.dev API key from https://21st.dev/magic/console.

For Codex plugin setup, use the available plugin workflow if present. If the user already has the key locally, the command pattern is:

$env:API_KEY="YOUR_21ST_DEV_KEY"
npx -y @21st-dev/magic@latest

Do not store or print API keys in project files.

Step 5: Install Advanced Design Skills

Resolve the built-in skill installer helper:

$codexHome = if ($env:CODEX_HOME) { $env:CODEX_HOME } else { Join-Path $HOME '.codex' }
$skillInstaller = Join-Path $codexHome 'skills\.system\skill-installer\scripts\install-skill-from-github.py'

Install the main Taste skill:

python $skillInstaller --repo Leonxlnx/taste-skill --path skills/taste-skill

Install Emil Design Engineering:

python $skillInstaller --repo emilkowalski/skills --path skills/emil-design-eng

Install Impeccable:

python $skillInstaller --repo pbakaus/impeccable --path skill --name impeccable

Install Stitch skills:

python $skillInstaller --repo google-labs-code/stitch-skills --path plugins/stitch-design/skills/code-to-design plugins/stitch-design/skills/extract-design-md plugins/stitch-design/skills/extract-static-html plugins/stitch-design/skills/generate-design plugins/stitch-design/skills/manage-design-system plugins/stitch-design/skills/upload-to-stitch plugins/stitch-build/skills/react-components plugins/stitch-build/skills/remotion plugins/stitch-build/skills/shadcn-ui plugins/stitch-utilities/skills/design-md plugins/stitch-utilities/skills/enhance-prompt plugins/stitch-utilities/skills/stitch-loop plugins/stitch-utilities/skills/taste-design

If a destination already exists, do not overwrite it automatically. Report that it is already installed.

Step 6: Optional Stitch Plugin Marketplace

For full Stitch plugin integration, add the Stitch marketplace when Codex plugin CLI is available:

codex plugin marketplace add google-labs-code/stitch-skills --ref main --sparse .agents/plugins --sparse plugins/stitch-design --sparse plugins/stitch-build --sparse plugins/stitch-utilities

Stitch workflows require the Stitch MCP server and credentials. Do not claim Stitch is fully ready until the MCP server is visible in the active tools.

Step 7: Verify

Run:

$codexHome = if ($env:CODEX_HOME) { $env:CODEX_HOME } else { Join-Path $HOME '.codex' }
Get-ChildItem (Join-Path $codexHome 'skills') -Directory | Sort-Object Name | Select-Object -ExpandProperty Name

Expected important entries:

• taste-skill
• emil-design-eng
• impeccable
• code-to-design
• generate-design
• manage-design-system
• react-components
• shadcn-ui
• design-md
• enhance-prompt
• stitch-loop
• taste-design

Done Message

When finished, summarize what installed, what failed if anything, and say:

Restart Codex to pick up the new skills.

Then the user can ask for premium website work using:

• website-builder-setup
• ui-ux-pro-max
• taste-skill
• emil-design-eng
• impeccable
• Stitch skills such as generate-design, stitch-loop, code-to-design, or react-components
