Excalidraw
Use this built-in skill when the user wants an editable sketch-style diagram rather than a polished presentation graphic.
Core rules
- Favor clarity, editable structure, and grouping over pixel-perfect ornament.
- Reduce each frame to the essential entities, flows, and callouts.
- Keep spatial grouping meaningful so the drawing still reads after edits.
- Preserve a human sketch feeling without making the content vague.
Default workflow
- Define the scene: entities, lanes, callouts, and arrows.
- Group related items and keep one dominant reading direction.
- Use concise labels and a restrained number of visual accents.
- Check that the diagram remains understandable after export or handoff.
Guardrails
- Do not pack dense prose into the drawing.
- Do not treat visual styling as a substitute for good structure.
- Do not output a sketch that loses the underlying logic of the flow.
