Thanveer1086/whiteBoardDiagram-Skills ? reverse-engineered prompt

Build me a small reusable AI skill that helps coding agents make whiteboard style diagrams that look hand drawn and sketchy, like real marker drawings on a whiteboard.

I want it to work with common agents like Cursor, Claude Code, Windsurf, Copilot, and similar tools, so include clear setup files and simple instructions for each one. The skill should guide the agent to create diagrams in a few styles, like flow charts, architecture layouts, kanban boards, mind maps, comparisons, timelines, and simple pipeline views.

Please make the output feel polished and human, with imperfect borders, pastel colors, numbered steps, little icons or emojis, and hand drawn fonts where possible. It should be able to output diagrams in formats like Mermaid, SVG, Excalidraw, or HTML depending on what makes sense.

If you need to check current docs or examples for the diagram tools, go ahead and look them up online. Keep the project clean, easy to copy into other repos, and include example prompts or reference files so someone can use it right away.
