 # Website Builder Setup
 This skill walks you through installing everything you need to build professional, animated websites with Claude Code. No coding experience required.
 ## What Gets Installed
 | Tool | What it does |
 |------|-------------|
 | **UI/UX Pro Max** | Gives Claude access to 50+ design styles, 161 color palettes, 57 font pairings. Your sites look designed, not generated. |
 | **Framer Motion** | Adds smooth animations — page transitions, hover effects, scroll reveals. Makes sites feel alive. |
 | **21st.dev Magic** | A library of 100+ polished React components Claude can pull from. Production-quality building blocks. |
 ## Workflow
 When this skill is triggered, walk the user through each step one at a time. Be encouraging and clear — assume they have zero coding experience. If any step fails, don't stop. Acknowledge it, give them the manual command, and keep moving.
 ---
 ### Step 1: Check Prerequisites
 > Before we start, let me make sure you have what we need.
 Run this silently:
 ```bash
 node --version 2>&1 && npm --version 2>&1
 ```
 - If Node.js is installed → say "You're good — Node.js is installed. Let's go."
 - If NOT installed → say:
 > You need Node.js first. Go to https://nodejs.org and download the LTS version. Install it, restart your terminal, then come back and run `/website-builder-setup` again. Takes 2 minutes.
 Stop here if Node is missing.
 ---
 ### Step 2: Install UI/UX Pro Max
 > **Step 1 of 3: UI/UX Pro Max**
 >
 > This gives me a massive design library — 50+ styles, 161 color palettes, 57 font pairings. When you ask me to build a website, I'm pulling from a real design system instead of guessing. This is why the output won't look like generic AI slop.
 >
 > Installing now...
 Run:
 ```bash
 npm install -g uipro-cli 2>&1
 ```
 Then:
 ```bash
 uipro init --ai claude 2>&1
 ```
 - On success → "UI/UX Pro Max is installed. Your design stack is ready."
 - On failure → "Hit a snag. You can try manually later: `npm install -g uipro-cli && uipro init --ai claude`. Let's keep going."
 ---
 ### Step 3: Install Framer Motion
 > **Step 2 of 3: Framer Motion**
 >
 > This teaches me how to add real animations to your websites — smooth page transitions, hover effects, scroll-triggered reveals. The stuff that makes a $500 site look like a $10,000 site.
 >
 > Installing now...
 Run:
 ```bash
 npm install framer-motion 2>&1
 ```
 - On success → "Framer Motion is installed. Your sites will have real animations now."
 - On failure → "Hit a snag. You can try manually later: `npm install framer-motion`. Moving on."
 ---
 ### Step 4: Set Up 21st.dev Magic
 > **Step 3 of 3: 21st.dev Components**
 >
 > This connects me to a library of 100+ beautifully designed React components. Instead of building everything from scratch, I pull from production-quality building blocks — buttons, navbars, hero sections, cards, footers — all pre-designed and ready to use.
 >
 > This one needs a free API key. Here's how to get it:
 >
 > 1. Go to **https://21st.dev/magic/console**
 > 2. Sign up or log in (it's free)
 > 3. Copy your API key
 > 4. Paste it here when I ask for it
 Wait for the user to provide their API key.
 Once they provide it, add the MCP server to their Claude Code config:
 Read `~/.claude.json`, find the `mcpServers` object, and add:
 ```json
 "21st-dev-magic": {
  "command": "npx",
  "args": ["-y", "@21st-dev/magic@latest"],
  "env": {
    "API_KEY": "THEIR_KEY_HERE"
  }
 }
 ```
 After writing the config:
 > 21st.dev Magic is connected. You'll need to restart Claude Code for this one to kick in — just close and reopen your terminal after we're done.
 ---
 ### Step 5: Done
 > **You're all set.** Here's what you just installed:
 >
 > - **UI/UX Pro Max** — 50+ styles, 161 palettes, 57 font pairings
 > - **Framer Motion** — smooth, professional animations
 > - **21st.dev Magic** — 100+ production-ready components
 >
 > **To build your first website, just tell me:**
 > - What your business does
 > - Who it's for
 > - What vibe you want (dark, minimal, bold, playful, etc.)
 >
 > I'll handle the rest. Try something like:
 >
 > *"Build me a landing page for my consulting business targeting small business owners. Dark theme, modern, with animations."*
 >
 > **Important:** Restart Claude Code first so 21st.dev loads in. Then let's build something.
 ## Rules
 - Walk through each step ONE AT A TIME
 - Never dump all instructions at once
 - If any install fails, don't stop — acknowledge, give manual command, keep moving
 - Be encouraging and casual throughout
 - Assume zero coding experience
 - After everything is installed, prompt them to build their first site

 # LookAtU: Product Plan (PRD)
 ## What is it? (the 4th-grade version)
 LookAtU is a helper for parents. The parent has an app. The child has an app. The parent can see where the child is, see what the child does on the phone, choose which apps the child can use, and check calls and messages. If the child is in danger, the child taps a big **panic button** and the parent gets an alert right away.
 ## Who is it for?
 - **Parents** of kids who have their own phone.
 - **Kids**, who need a simple way to ask for help.
 ## Core features
 1. **Live location**: the parent sees where the child is, any time.
 2. **Activity monitor**: which apps are used and for how long.
 3. **App control**: the parent can allow, block, or limit apps, and approve new installs.
 4. **Calls and messages**: the parent can check call history and messages.
 5. **Panic button**: the child taps once. The parent gets an alert with the child's location.
 ## Trust and safety rules (built in from day one)
 - The child **knows** the app is on their phone. No hidden spying. This is the honest way to do it, and app stores require it.
 - The parent signs in with a real account and a strong password.
 - Data is private and encrypted. Only the parent sees it.
 - Rules about monitoring messages differ by country and by the child's age. We must check the law for each country before launch.
 ## Phased roadmap
 ### Phase 1: Quick win (TODAY)
 A good-looking website (one page) that explains LookAtU and collects sign-ups.
 - Hero, 5 feature cards, "how it works", trust section, FAQ
 - Waitlist form that checks the email is real-looking
 - Works on phones and computers
 - **Done when:** page loads with no errors and the form and buttons work.
 ### Phase 2: Make it real
 - Connect the waitlist form to a real service so emails are saved.
 - Add animations (Framer Motion) and better pictures.
 - Add privacy and terms pages.
 ### Phase 3: Parent accounts
 - Sign up and log in.
 - A simple parent dashboard (website).
 - Link a parent to a child.
 ### Phase 4: Phone apps
 - Child app and parent app (Android first, then iPhone).
 - Live location and the panic button with alerts (push notifications and SMS).
 ### Phase 5: Monitoring and control
 - App usage, app blocking and install approval.
 - Call and message history (after legal review).
 ## How we test at every phase
 1. Page loads with **no errors**.
 2. Buttons and forms **work**.
 3. Real services (database, email, maps, alerts) **work**.
 4. **Security check**: passwords, private data, no secrets in code.
 ## Open questions for the owner
 - Which countries first?
 - Free or paid? (price)
 - Android first, or iPhone first?
 - Final name and logo?

 <h2>The LookAtU app (coming later)</h2>
 <p>The app will handle location, activity and messages of children. Before launch we will publish full details here: what is collected, how it is protected, how long it is kept, and how a parent can delete it. The child will always be able to see that the app is installed.</p>
