Build an AI Diagram Generator with Claude Code | Excalidraw Skill Tutorial

Build an AI Diagram Generator with Claude Code | Excalidraw Skill Tutorial In this video I walk through how I built a Claude Code skill that automatically generates Excalidraw diagrams from simple prompts. This has quickly become one of the most useful tools in my workflow. Instead of manually sketching ideas, Claude can generate clean visual diagrams for workflows, automation systems, business processes, and YouTube concepts in seconds. I’ll show you how to set up Claude Code, create a proper Claude.md system file, install a skill builder framework, and use custom skills that generate both simple and advanced diagrams automatically. This setup is useful for developers, founders, creators, automation builders, and anyone who thinks visually.
