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

1. 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

1. Read references/best-practices.md for quality guidelines

1. Structure content following best practices:

- Title slide with <!-- _class: lead --> - Concise h2 titles (5-7 characters in Japanese) - 3-5 bullet points per slide - Adequate whitespace

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

1. Save to /mnt/user-data/outputs/ with .md extension

Creating Slides Process

Basic Workflow

1. Understand requirements

- Identify content: title, topics, key points - Determine target audience - Assess formality level

1. Select theme

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

1. Apply template

- Load appropriate template from assets/ - CSS is already embedded - no external files needed - Maintain template structure

1. Structure content

- Title slide: <!-- _class: lead --> + h1 - Content slides: h2 title + bullet points - Keep titles to 5-7 characters (Japanese) - Use 3-5 bullet points per slide

1. Refine quality

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

1. Add images

- If needed, consult references/image-patterns.md - Common: ![bg right:40%](image.png) for side images - Use proper Marp image syntax

1. Output file

- Save to /mnt/user-data/outputs/ - 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

1. Apply best practices automatically:

- Shorten titles to 5-7 characters - Limit bullet points to 3-5 items - Add adequate whitespace - Use consistent structure

1. Enhance visual hierarchy:

- Use h3 for sub-sections when appropriate - Break up dense text into multiple slides - Ensure logical flow (intro → body → conclusion)

1. 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: ![bg right:40%](image.png) - Image on right, text on left
• Centered: ![w:600px](image.png) - Centered with specific width
• Full background: ![bg](image.png) - Full-screen background
• Multiple images: Multiple ![bg] declarations

Example lecture pattern:

## Slide Title

![bg right:40%](diagram.png)

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

File Output

Always save the final Marp file to /mnt/user-data/outputs/ with .md extension:

• presentation.md
• seminar-slides.md
• lecture-materials.md
