## What it does

The skill hands the agent Marp syntax: `---` between slides, a frontmatter block with `marp: true`, a theme and a slide size. You describe the slide structure, the agent writes the file and runs the conversion.

Inside are command examples like `marp slides.md -o presentation.pptx`, the built-in themes `default`, `gaia` and `uncover`, the `lead` and `invert` classes, sized images such as `![width:500px](image.png)`, tables and code blocks. There are Python and Node.js starting points too: a `subprocess.run` wrapper and a `marpCli` call from `@marp-team/marp-cli`.

Conversion runs through the Marp CLI, so that has to be installed separately — without it the command just won't resolve. The skill metadata also names the `office-mcp` MCP server with a `pptx_to_html` tool, though that goes the other way, from PowerPoint back to HTML.

## When to use it
- build a slide deck from an existing Markdown draft
- export notes to PDF without laying anything out by hand
- apply one theme and page numbers across every slide
- place an image at a set width or as a slide background
- generate a presentation from structured data in a script

## Example prompts

# HTML/Markdown to PowerPoint Skill

## Overview

This skill enables conversion from Markdown or HTML to professional PowerPoint presentations using **Marp** (Markdown Presentation Ecosystem). Create beautiful, consistent slides using simple Markdown syntax with CSS-based themes.

## How to Use

1. Provide Markdown content structured for slides
2. Optionally specify a theme or custom styling
3. I'll convert it to PowerPoint, PDF, or HTML slides

**Example prompts:**
- "Convert this markdown to a PowerPoint presentation"
- "Create slides from this outline using Marp"
- "Turn my notes into a presentation with the gaia theme"
- "Generate a PDF slide deck from this markdown"

## Domain Knowledge

### Marp Fundamentals

Marp uses a simple syntax where `---` separates slides:

```markdown
---
marp: true
theme: default
---

# Slide 1 Title

Content for first slide

---

# Slide 2 Title

Content for second slide
```

### Command Line Usage

```bash
# Convert to PowerPoint
marp slides.md -o presentation.pptx

# Convert to PDF
marp slides.md -o presentation.pdf

# Convert to HTML
marp slides.md -o presentation.html

# With specific theme
marp slides.md --theme gaia -o presentation.pptx
```

### Slide Structure

#### Basic Slide
```markdown
---
marp: true
---

# Title

- Bullet point 1
- Bullet point 2
- Bullet point 3
```

#### Title Slide
```markdown
---
marp: true
theme: gaia
class: lead
---

# Presentation Title

## Subtitle

Author Name
Date
```

### Frontmatter Options

```yaml
---
marp: true
theme: default          # default, gaia, uncover
size: 16:9              # 4:3, 16:9, or custom
paginate: true          # Show page numbers
header: 'Company Name'  # Header text
footer: 'Confidential'  # Footer text
backgroundColor: #fff
backgroundImage: url('bg.png')
---
```
