A desktop canvas where Claude Code or Codex draws diagrams of the code it has written.

Why it's useful

Instead of reading a wall of diff, you ask the agent to explain a branch and it draws the structure, the API and the changes on a canvas you can look over. Handy when an agent has built something and you want to know what it actually did.

What it needs

Claude Code, Codex or another coding agent. Early version; sends anonymous usage data (no code) unless you switch it off.
