# Preview Markdown Skill

GitHub-flavored Markdown viewer that generates beautiful HTML with syntax highlighting and automatic table of contents.

## Usage

```bash
# Preview a Markdown file
/preview README.md

# Pipe Markdown content (preferred for temporary content)
cat docs.md | /preview
echo "# Hello\n\nThis is **markdown**" | /preview

# With custom background color
/preview article.md --background "#ffffff"
```

**Best Practice:** For temporary or generated content, prefer piping over creating temporary files. This avoids cluttering your filesystem and the content is automatically cleaned up.

## Options

The script works with sensible defaults but supports these flags for flexibility:

- `-o, --output PATH` - Custom output path
- `--no-browser` - Skip browser, output file path only
