Inputs

Input	Required	Default	Description
supermodel-api-key	Yes	—	Supermodel API key
site-name	No	<repo> Architecture Docs	Display name for the docs site
base-url	No	GitHub repo URL	Base URL for the generated site
output-dir	No	./arch-docs-output	Output directory relative to workspace

entity-count	Number of entities generated
page-count	Total HTML pages generated

How It Works

1. Zips the repository (skipping .git/, node_modules/, binaries, large files)
2. Sends the zip to the Supermodel API for code analysis
3. Receives a graph JSON with nodes (files, functions, classes, domains) and relationships
4. Runs graph2md to convert the graph to markdown
5. Runs pssg to build a static site with the bundled templates

Custom Templates

To customize the look of the generated site, create a templates/ directory in your repository with your own HTML templates and pass it via the templates-dir input:

- uses: supermodeltools/arch-docs@main
  with:
    supermodel-api-key: ${{ secrets.SUPERMODEL_API_KEY }}
    templates-dir: './my-templates'

See the bundled templates/ directory for the default templates and available template variables.

Example Output

The generated site includes:

• Homepage with architecture overview chart and codebase composition treemap
• Entity pages with dependency diagrams, relationship graphs, and source code
• Taxonomy pages for node types, languages, domains, subdomains, directories, extensions, and tags
• Full-text search with keyboard navigation
• SEO metadata, Open Graph tags, JSON-LD structured data, sitemap, and RSS feed
