# Medium Article Converter

Convert blog posts to Medium-ready format with proper HTML structure and image handling.

**Usage:** `$ARGUMENTS`

**Examples:**
```bash
/publisher:medium my-post           # Default English
/publisher:medium my-post ja        # Japanese
/publisher:medium article.md        # From file path
/publisher:medium https://blog.com/post  # From URL
```

**Process:**

1. **Parse Input & Detect Source**
   - File path, URL, or blog post slug
   - Optional language parameter (en/ja)

2. **Universal Input Detection**
   - **File**: Read markdown, PDF, HTML, or text
   - **URL**: WebFetch to retrieve content
   - **Slug**: Search codebase for blog post

3. **Convert to Medium Format**
   - Parse markdown and extract frontmatter
   - Convert to clean HTML suitable for Medium
   - Preserve headers, lists, code blocks, quotes
   - Add image upload markers for diagrams
   - Include image paths for easy upload reference

4. **Create HTML Preview File**
   - Generate `medium-article-[LANG].html` preview
   - Include one-click copy button
   - Add image upload instructions with file paths
   - Use Medium-style formatting and colors

5. **Open in Browser**
   - Open HTML preview file
   - Open Medium editor (https://medium.com/new-story)
   - User can copy HTML and paste into Medium
   - Follow image markers to upload diagrams

**Output:**
- HTML preview file with copy button
- Clear image upload markers
- File paths shown for each image
- Ready to paste into Medium editor

**Note**: Works universally - no dependencies required, just Read, Write, and Bash tools.
