Architecture Diagram Skill

Generate professional, dark-themed technical architecture diagrams as standalone HTML files with inline SVG graphics. No external tools, no API keys, no rendering libraries — just write the HTML file and open it in a browser.

Based on Cocoon AI's architecture-diagram-generator (MIT).

Workflow

1. User describes their system architecture (components, connections, technologies)
2. Generate the HTML file following the design system below
3. Save with write_file to a .html file (e.g. ~/architecture-diagram.html)
4. User opens in any browser — works offline, no dependencies

Output Location

Save diagrams to a user-specified path, or default to the current working directory:

./[project-name]-architecture.html
