Markdown To HTML

Use this skill when the user wants a Markdown file or Markdown string converted into a polished HTML page.

What this skill provides

• Deterministic conversion through pandoc
• Input from either a Markdown file or a raw Markdown string
• Custom HTML template support through --template /path/to/template.html
• Custom CSS support through --css /path/to/file.css
• Built-in HTML themes in assets/templates/ and assets/styles/
• Optional table of contents, numbered headings, metadata, and embedded assets

Quick workflow

1. Choose the input source. File input: pass --input-file /abs/path/file.md Raw string input: pass --markdown '...'
2. Choose a layout. Use --template for a fully custom Pandoc HTML template. Otherwise use --builtin-template.
3. Optionally add one or more CSS files with --css.
4. Set output with --output /abs/path/output.html.
5. Optional layout flags: Use --toc to render a table of contents panel. Use --no-body-background to remove the article card background, border, and shadow.

Built-in templates

• docs-slate: technical docs layout with restrained slate tones
• magazine-amber: editorial landing-page feel with warm contrast
• product-midnight: dark product narrative with stronger gradients
• serif-paper: print-inspired article layout

List them at runtime with:

python3 scripts/markdown_to_html.py --list-templates

Main command

python3 scripts/markdown_to_html.py \
  --input-file /abs/path/source.md \
  --output /abs/path/output.html \
  --builtin-template docs-slate \
  --toc \
  --number-sections \
  --embed-assets

Raw string example

python3 scripts/markdown_to_html.py \
  --markdown '# Release Notes\
\
- Added HTML export\
- Added built-in themes' \
  --output /abs/path/release.html \
  --builtin-template magazine-amber \
  --title 'Release Notes'

Template rules

• --template overrides --builtin-template
• Built-in templates automatically include their matching built-in CSS
• Extra --css files are appended after the built-in CSS, so local overrides win
• --number-sections enables Pandoc heading numbering in the generated HTML
• When --number-sections is enabled, avoid manually writing heading prefixes like 1., 2.1, or 3.2 inside the Markdown heading text, or the output will show duplicated numbering such as 1.2.1 2.1 Title
• When --toc is omitted, the built-in templates render only the article body and expand it to the full content width
• --no-body-background removes the article panel background, border, and shadow while keeping the overall page theme

Bundled files

• Converter: scripts/markdown_to_html.py
• Built-in templates: assets/templates/*.html
• Built-in CSS themes: assets/styles/*.css

Notes

• This skill expects pandoc to be installed and available on PATH
• Custom templates should be valid Pandoc HTML templates and include $body$
• If you want a table of contents without visible heading numbers in the HTML body, use --toc without --number-sections
