## From README

Excalidraw Diagram Creator Generate .excalidraw JSON files that argue visually, not just display information. If the user asks you to set up this skill (renderer, dependencies, etc.), see README.md for instructions. Customization All colors and brand-specific styles live in one file: references/color-palette.md. Read it before generating any diagram and use it as the single source of truth for all color choices — shape fills, strokes, text colors, evidence artifact backgrounds, everything. To make this skill produce diagrams in your own brand style, edit color-palette.md. Everything else in this file is universal design methodology and Excalidraw best practices. --- Core Philosophy Diagrams should ARGUE, not DISPLAY. A diagram isn't formatted text. It's a visual argument that shows relationships, causality, and flow that words alone can't express. The shape should BE the meaning. The Isomorphism Test: If you removed all text, would the structure alone communicate the concept?
