Why this, not just another Excalidraw MCP?

Excalidraw's official MCP and most community servers solve plumbing: get an agent to emit valid JSON and render it. They produce correct boxes-and-arrows.

This pack solves taste: an opinionated methodology — the isomorphism test, evidence artifacts, multi-zoom architecture, container discipline, one-accent-per-diagram — that decides what to draw and why, so the output is a visual argument that teaches instead of a labeled grid. That's the part a weekend of MCP code can't copy, and it's why the book gallery looks the way it does.

Plumbing is a commodity now. Quality isn't.

Proof

This skill drew 77 diagrams for the published technical book From Copilot to Colleague — argument spines, chapter openers, concept figures, and inline explainers, all from the methodology in this repo. No other Excalidraw generator can point at a corpus like that. A curated set — the book's argument spine plus all ten chapter openers — ships as source .excalidraw files in examples/book; the full 77 are live across fromcopilottocolleague.com.

Methodology

Diagrams are arguments. The shape should BE the meaning.

• Isomorphism Test: would the structure alone communicate the concept?

• Evidence artifacts: real code snippets, actual API names, concrete formats — not placeholder text.

• One accent per diagram. Two means a competing argument; split it.
