Diagram Design
Agent skill that draws branded diagrams as standalone HTML and SVG files
What it is
An agent skill for Claude Code, Codex, Cursor, GitHub Copilot and other Agent Skills hosts that turns plain-language requests into finished diagrams. It covers dozens of types, from architecture and sequence diagrams to quadrants, and writes each one as a single HTML file with inline SVG. It can pull a site's palette and fonts so diagrams match a brand, import from draw.io, Mermaid or Excalidraw, and export to PNG or SVG. Developers and writers who want clean, presentable diagrams from their coding agent without hand-tuning Mermaid output are the intended users.
