What Excalidraw Diagrams makes
This skill turns a plain description into a diagram file. Excalidraw is a free whiteboard-style drawing tool. The skill writes a .excalidraw file that you open directly in it, so you can then move, restyle and share the shapes.
It works in steps: understand the request, choose a diagram type, pull out the key items and connections, generate the file and save it with instructions. It supports flowcharts, relationship diagrams, mind maps, architecture diagrams, data flow diagrams, swimlane business flows, class diagrams, sequence diagrams and database (ER) diagrams, with a starter template for each.
Best for: Anyone who wants a quick editable diagram without drawing every box.
- Nine diagram types, each with a template
- Output is a normal .excalidraw file
- Helper scripts to add arrows and icons
- Works from plain descriptions
- Optional icon libraries
