Claude Code System Prompts

Create a whiteboard artifact - a shared sketch canvas for wireframe-fidelity diagrams (boxes, databases, decision diamonds, sticky notes, arrows, freehand pen, text) that you and the user both draw on. The user sketches and hits Publish; this session is woken, reads the board (scene data plus a picture of it), and answers by drawing back on the same canvas - or plans from what they drew. Use when the user asks for a whiteboard, wants to sketch a design or diagram to talk through, or wants to draw something and have you answer on the canvas or plan from it. Only for CREATING a new whiteboard; an existing one is read and answered through its published artifact.
