A Claude Code skill for generating slides from Markdown

What is this?

A Claude Code skill that generates presentation slides from Markdown. Just describe what you want, or provide an existing .md file, and Claude will use proper tools to create the slides — including AI-generated diagrams and illustrations via mcp-image.

# In Claude Code:
/md-slides "Create a 5-slide presentation about Python async programming"

Claude will:

1. Use or Write the Markdown content
2. Generate diagrams/charts with AI (optional, requires mcp-image)
3. Choose the best tool (Marp, Beamer, etc.)
4. Generate PDF/PPTX/HTML output

Installation

# Clone this repo
git clone https://github.com/zl190/md-slides.git

# The skill is in .claude/skills/md-slides/
# Claude Code auto-discovers skills in your project

Usage

The skill uses natural language — just describe what you want:

# Generate from a topic
/md-slides "Create slides about machine learning basics"

# Convert existing markdown
/md-slides "Convert slides.md to PDF"

# With style preferences
/md-slides "Create slides about Q4 results, executive style, keep it brief"

Flavors

Claude understands these style preferences:

Examples

# Executive summary
/md-slides "Q4 results for management, brief and professional"

# Technical tutorial
/md-slides "Git branching tutorial for developers, detailed with code examples"

# Research presentation
/md-slides "ML research findings, academic style, bilingual"

Visual Templates

Visual templates ensure consistent visual output (fonts, CSS, rendering). Without them, slides may render differently each time due to font variations or CSS inconsistencies.

Templates are in .claude/skills/md-slides/templates/visual/:

Title Slide	Content Slide

Chinese template example

Title Slide	Content Slide

How It Works

Claude automatically applies the appropriate visual template based on language. The template provides:

• Tested frontmatter (marp settings, theme, size)
• Consistent font stack for reliable rendering
• CSS that works across platforms

Custom Looks

Add your own templates to templates/visual/:

# My Corporate Look

\`\`\`yaml
---
marp: true
theme: gaia
style: |
  section { font-family: 'Corporate Font', sans-serif; }
  h1 { color: #company-blue; }
---
\`\`\`

## Rules
- Use frontmatter exactly as shown
- ...

See templates/visual/README.md for details.

Supported Tools

The skill automatically selects the best tool:

Note: Marp only requires Node.js (npm install -g @marp-team/marp-cli). Beamer requires a full LaTeX installation (sudo apt install texlive-full ~4GB).

Visual Comparison

Marp vs Beamer Output

Marp (Gaia Theme)	Beamer (Metropolis)

Code & Math Rendering

Code (Marp)	Math (Beamer)

AI Image Generation (Optional)

Generate diagrams, flowcharts, and illustrations for your slides using mcp-image (powered by Google Gemini).

claude mcp add mcp-image \
  --env GEMINI_API_KEY=your-api-key \
  --env IMAGE_OUTPUT_DIR=/path/to/images \
  -- npx -y mcp-image

# Ask for slides with visuals
/md-slides "Create architecture slides with diagrams for our microservices system"

Claude will generate images like flowcharts, architecture diagrams, and timelines, then embed them in your slides.

Manual Usage (without Claude)

If you want to use the tools directly:

npm install -g @marp-team/marp-cli

marp slides.md -o slides.pdf
marp slides.md -o slides.pptx
marp slides.md -o slides.html

sudo apt install pandoc texlive-xetex

pandoc slides.md -t beamer --pdf-engine=xelatex -o slides.pdf

pandoc slides.md -t revealjs -s -o slides.html

Research

This skill is based on research comparing 6 markdown-to-slides tools for LLM integration. See the full report (Chinese).

Key finding: Marp and python-pptx scored highest (24/25) for LLM integration due to simple CLI, text-based input, and clear error messages.
