But teams building agent-driven internal tooling hit a real problem: the design reasoning behind what an agent builds evaporates in chat scrollback. Whiteboard gives humans and coding agents like Claude Code a shared canvas to work through software design, with AST-aware semantic diffs so changes are legible at the structure level and decision logging so the \"why\" is retained. For an engineering-led growth team standardizing on coding agents, that shared surface is where design intent stays visible. The honest read: it is young (created 2026-08-18) though actively shipping, and the quality of the semantic diffs and decision log is best judged against your own repo before you adopt it as a team surface."
