SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires cryptography, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Excalidraw Diagram Skill enables rapid creation of hand-drawn style diagrams by authoring standard Excalidraw element JSON and saving it as .excalidraw files. These files can be opened at excalidraw.com for viewing/editing or uploaded to generate shareable links without requiring accounts or external rendering libraries.

Core Features & Use Cases

Generate .excalidraw files from element JSON for architecture diagrams, flowcharts, sequence diagrams, and concept maps.
Open, edit, and share diagrams directly in Excalidraw via shareable links.
Optional: upload provided via script to produce a public link (through the scripts/upload.py) with encryption.

Quick Start

Save your diagram elements as an .excalidraw file and optionally upload to Excalidraw to obtain a shareable link.
