hand-drawn-diagrams

Hand-Drawn Diagrams is a thin catalogue entry that advertises an upstream skill for generating hand-drawn Excalidraw-style diagrams from a text prompt. According to its description it produces an animated SVG, a hosted edit link, and a PNG export, and is designed to work across agents that support standard skill paths, including Claude Code, Codex, and Gemini CLI. It is triggered by phrases such as "excalidraw", "hand drawn diagram", "sketch diagram", or "whiteboard diagram".

Importantly, this is honestly a catalogue/pointer entry rather than a full implementation. The SKILL.md is curated from @muthuishere and states plainly that the entry exists so an Open Design agent discovers the skill during planning; to run the full workflow with its original assets, scripts, and references, the user must install the upstream bundle from the linked GitHub repository into their active agent's skills directory. The only shell guidance provided is an 'open' command to inspect the upstream README.

This suits users who want quick, informal diagrams (architecture sketches, flowcharts, whiteboard-style visuals) and are comfortable installing the referenced upstream package to get the actual generation logic. As shipped, the entry itself carries no diagram-generation code; its value is discovery and routing to the upstream project.
