What changed

Whiteboard is an open-source desktop app that connects to coding agents such as Claude Code and Codex. Agents can use its SDK to draw on an in-app canvas, while users can link visualizations and agent-trace excerpts to code and review changes with an AST-aware diff viewer.

Why it matters

The app brings diagrams, agent decision traces, and code review into one workspace. It runs against local checkouts, but currently does not support editing files in the app.
