Diagram Design

An agent skill by Cathryn Lavery that draws diagrams in your brand: describe what you want in a sentence and it renders one self-contained HTML + SVG file, 44+ diagram types from architecture and Sankey to Wardley maps and database schemas. Point it at your site and it matches your fonts and colors in about a minute. No Mermaid slop, no build step, opens offline. For Claude Code, Codex, Cursor and more.
