# Beginner (Starter) Skill

## Actions

| Action | Description | Example |
|--------|-------------|---------|
| `init` | Project initialization (/init-starter feature) | `/starter init my-portfolio` |
| `guide` | Display development guide | `/starter guide` |
| `help` | Beginner help | `/starter help` |

### init (Project Initialization)
1. Create project directory structure (HTML/CSS/JS or Next.js)
2. Generate package.json (when Next.js selected)
3. Create agents.md (Level: Starter specified)
4. Create docs/ folder structure (for PDCA documents)
5. Initialize .hmcmkit-memory.json

### guide (Development Guide)
- Analyze current project state
- Suggest next steps appropriate for Starter level
- Phase 1-3 focused Pipeline guide

### help (Beginner Help)
- Explain HTML/CSS/JS basic concepts
- Answer frequently asked questions
- Provide example code

## Target Audience

- Those learning programming for the first time
- Those who want to create a simple website
- Those who need a portfolio site

## Tech Stack

### Option A: Pure HTML/CSS/JS (For Complete Beginners)

```
HTML5        → Web page structure
CSS3         → Styling
JavaScript   → Dynamic features (optional)
```

### Option B: Next.js (Using Framework)

```
Next.js 14+  → React-based framework
Tailwind CSS → Utility CSS
TypeScript   → Type safety (optional)
```

### Language Tier Guidance (v1.3.0)

> **Recommended**: Tier 1 languages only (Python, TypeScript, JavaScript)
>
> Starter level focuses on AI-Native development with maximum AI tool support.

| Tier | Allowed | Reason |
|------|---------|--------|
| Tier 1 | ✅ Yes | Full AI support, Vibe Coding optimized |
| Tier 2 | ⚠️ Limited | Consider Dynamic level instead |
| Tier 3-4 | ❌ No | Upgrade to Dynamic/Enterprise |

## Project Structure

### Option A: HTML/CSS/JS

```
project/
├── index.html          # Main page
├── about.html          # About page
├── css/
│   └── style.css       # Styles
├── js/
│   └── main.js         # JavaScript
├── images/             # Image files
├── docs/               # PDCA documents
│   ├── 01-plan/
│   └── 02-design/
└── README.md
```

### Option B: Next.js

```
project/
├── src/
│   ├── app/
│   │   ├── layout.tsx      # Common layout
│   │   ├── page.tsx        # Main page

```

## Core Concept Explanations

### HTML (Web Page Structure)

```html
<!-- Basic structure -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>My Website</title>
    <link rel="stylesheet" href="css/style.css">
</head>
<body>
    <header>Header</header>
    <main>Main content</main>
    <footer>Footer</footer>
</body>
</html>
```

### CSS (Styling Web Pages)

```css
/* Basic styles */
body {
    font-family: 'Inter', sans-serif;
    margin: 0;
    padding: 0;
}

/* Center alignment */
.container {
    max-width: 1200px;
    margin: 0 auto;
    padding: 20px;
}

/* Responsive (mobile support) */
@media (max-width: 768px) {
    .container {
        padding: 10px;
    }
}
```

### Next.js App Router (Creating Pages)

```tsx
// app/page.tsx - Main page
export default function Home() {
  return (
    <main className="container mx-auto p-4">
      <h1 className="text-3xl font-bold">
        Welcome!
      </h1>
    </main>
  );
}

// app/about/page.tsx - About page
// URL: /about
export default function About() {
  return (
    <div className="container mx-auto p-4">
      <h1>About</h1>
      <p>I am ...</p>
    </div>
  );
}
```

### Tailwind CSS (Quick Styling)

```tsx
// Frequently used classes
<div className="
  container    // Center alignment
  mx-auto      // Auto left/right margin
  p-4          // Padding 16px
  text-center  // Center text
  text-xl      // Large text
  font-bold    // Bold text
  bg-blue-500  // Blue background
  text-white   // White text
  rounded-lg   // Rounded corners
  hover:bg-blue-600  // Color change on hover
">
```

## Deployment Methods

### GitHub Pages (Free)

```
1. Create GitHub repository
2. Push code
3. Settings → Pages → Source: main branch
4. Access at https://username.github.io/repo-name
```

### Vercel (Recommended for Next.js)

```
1. Sign up at vercel.com (GitHub integration)
2. "New Project" → Select repository
3. Click "Deploy"
4. URL automatically generated
```

## Limitations

```
❌ Login/Registration (requires server)
❌ Data storage (requires database)
❌ Admin pages (requires backend)
❌ Payment features (requires backend)
```

## When to Upgrade

Move to **Dynamic Level** if you need:

```
→ "I need login functionality"
→ "I want to store data"
→ "I need an admin page"
→ "I want users to communicate with each other"
```

## hmcmkit Features for Starter Level (v1.5.1)

### Output Style: hmcmkit-learning (Recommended)

For the best learning experience, activate the learning output style:

```
/output-style hmcmkit-learning
```

This provides:
- Learning points after each task explaining what you did and why
- TODO(learner) markers encouraging hands-on practice
- Concept explanations adjusted for beginner difficulty

### Agent Memory (Auto-Active)

hmcmkit agents automatically remember your learning progress across sessions.
No setup needed — your `starter-guide` agent uses `user` scope memory,
so learning context persists even across different projects.

### Agent Teams

Agent Teams is not available for Starter level projects.
When you upgrade to Dynamic level, you unlock 2-teammate parallel PDCA mode.

## Common Mistakes

| Mistake | Solution |
|---------|----------|
| Image not showing | Check path (`./images/photo.jpg`) |
| CSS not applied | Check link tag path |
| Page navigation not working | Check href path (`./about.html`) |
| Broken on mobile | Check `<meta name="viewport">` tag |
