Field notes
The page describes diagrams as files that can live beside a codebase, with a .draftcanvas file used to move between the desktop and browser editors. Its agent setup requires enabling access in desktop settings and installing the Draft Canvas skill. A sample brief asks agents to use C4 views, attach relevant code snippets, and mark inferences, making the intended review trail explicit.
