Excalidraw Diagram Skill: Generate Visually Argumentative Diagrams via Claude
tom_doerr · x · 2026-08-25
GitHub project excalidraw-diagram-skill enables coding agents like Claude Code to generate beautiful Excalidraw diagrams from natural language.
Key Features:
- Visual Arguments: Diagrams mirror conceptual logic (fan-outs, timelines, convergence) rather than uniform grids.
- Evidence Artifacts: Supports embedding real code snippets and JSON payloads directly into technical diagrams.
- Visual Validation: A Playwright-based pipeline allows the agent to inspect its output, detect layout issues (overlaps, misalignments), and self-correct before delivery.
- Brand Customization: Colors and styles are centralized in a single file for easy branding.
