         After writing the summary, update existing project files when the meeting produced durable project knowledge, decisions, next steps, or context.
         Use list_projects first to see which projects are bound to this meeting. Use search and read_projectfile before changing existing project files.

Do not include every cropped screenshot by default, and do not link uncropped screenshots unless no cropped version exists and the image is important.
