## About

# Marp Slide Creator

Create professional, visually appealing Marp presentation slides with 7 pre-designed themes and built-in best practices.

## When to Use This Skill

Use this skill when the user:
- Requests to create presentation slides or Marp documents
- Asks to "make slides look good" or "improve slide design"
- Provides vague instructions like "良い感じにして" (make it nice) or "かっこよく" (make it cool)
- Wants to create lecture or seminar materials
- Needs bullet-point focused slides with occasional images

## Quick Start

### Step 1: Select Theme

First, determine the appropriate theme based on the user's request and content.

**Quick theme selection:**
- **Technical/Developer content** → tech theme
- **Business/Corporate** → business theme
- **Creative/Event** → colorful or gradient theme
- **Academic/Simple** → minimal theme
- **General/Unsure** → default theme
- **Dark background preferred** → dark or tech theme

For detailed theme selection guidance, read `references/theme-selection.md`.

### Step 2: Create Slides

1. **Read relevant references first**:
   - Always start by reading `references/marp-syntax.md` for basic syntax
   - For images: `references/image-patterns.md` (official Marpit image syntax)
   - For advanced features (math, emoji): `references/advanced-features.md`
   - For custom themes: `references/theme-css-guide.md`

2. Copy content from the appropriate template file:
   - `assets/template-basic.md` - Default theme (most common)
   - `assets/template-minimal.md` - Minimal theme
   - `assets/template-colorful.md` - Colorful theme
   - `assets/template-dark.md` - Dark mode theme
   - `assets/template-gradient.md` - Gradient theme
   - `assets/template-tech.md` - Tech/code theme
   - `assets/template-business.md` - Business theme

3. Read `references/best-practices.md` for quality guidelines

4. Structure content following best practices:
   - Title slide with ``
   - Concise h2 titles (5-7 characters in Japanese)
   - 3-5 bullet points per slide
   - Adequate whitespace

5. Add images if needed using patterns from `references/image-patterns.md`

6. Save to `ai-docs/slides/` with `.md` extension

## Creating Slides Process

### Basic Workflow

1. **Understand requirements**
   - Identify content: title, topics, key points
   - Determine target audience
   - Assess formality level

2. **Select theme**
   - Use quick selection rules above
   - If uncertain, consult `references/theme-selection.md`
   - Default to default theme if still unsure

3. **Apply template**
   - Load appropriate template from `assets/`
   - CSS is already embedded - no external files needed
   - Maintain template structure

4. **Structure content**
   - Title slide: `` + h1
   - Content slides: h2 title + bullet points
   - Keep titles to 5-7 characters (Japanese)
   - Use 3-5 bullet points per slide

5. **Refine quality**
   - Read `references/best-practices.md`
   - Ensure adequate whitespace
   - Maintain consistency
   - Keep text concise (15-25 chars per line)

6. **Add images**
   - If needed, consult `references/image-patterns.md`
   - Common: `` for side images
   - Use proper Marp image syntax

7. **Output file**
   - Save to `ai-docs/slides/`
   - Use descriptive filename like `presentation.md`

## Handling "Make It Look Good" Requests

When users give vague instructions like "良い感じにして", "かっこよく", or "make it cool":

1. **Infer theme from content**:
   - Business content → business theme
   - Technical content → tech or dark theme
   - Creative content → gradient or colorful theme
   - General → default theme

2. **Apply best practices automatically**:
   - Shorten titles to 5-7 characters
   - Limit bullet points to 3-5 items
   - Add adequate whitespace
   - Use consistent structure

3. **Enhance visual hierarchy**:
   - Use h3 for sub-sections when appropriate
   - Break up dense text into multiple slides
   - Ensure logical flow (intro → body → conclusion)

4. **Maintain professional tone**:
   - Match formality to content
   - Use parallel structure in lists
   - Keep technical terms consistent

## Image Integration

For slides with images, consult `references/image-patterns.md` for detailed syntax.

Common patterns:
- **Side image**: `` - Image on right, text on left
- **Centered**: `` - Centered with specific width
- **Full background**: `` - Full-screen background
- **Multiple images**: Multiple `![bg]` declarations

Example lecture pattern:
```markdown
## Slide Title

- Explanation point 1
- Explanation point 2
- Explanation point 3
```

## File Output

Always save the final Marp file to `ai-docs/slides/` with `.md` extension:
- `presentation.md`
- `seminar-slides.md`
- `lecture-materials.md`
