You can now review a task's code changes on the web with a file sidebar, a side-by-side split view, and collapsible unchanged lines. The diff opens on the same screen as the agent's conversation, and Create PR sits in that screen's header.
File sidebar. Once the diff pane is wide enough, the changed files move into a sidebar with the selected file's diff beside it. Filter the list by name or by change type, and move between files with j and k. A summary bar above the diff carries the file count, lines added and removed, and the change types in the diff. Narrow windows and phones keep the compact file selector.
Split view. The Unified / Split toggle in the summary bar puts deletions on the left and additions on the right, and the choice follows you from file to file.
Collapsed context. Runs of more than 12 unchanged lines collapse to an Expand N unchanged lines band, with three lines of context kept on each side. Image files render as image cards.
Load errors. When a diff cannot load, the panel names the cause: nothing pushed to the branch yet, a missing GitHub token, or the server's own error message.
