Diff Viewer

The diff viewer shows a file's uncommitted changes. Click a file in the Changes panel and it opens in the Diff pane of the right panel, so you can review an agent's edits without leaving the panel. Open in a tab moves it to a full diff tab in the main area.

The Diff Pane

A one-row header sits above the diff:

• The file path — the folder is dimmed and truncates from the left (…/chat/ChatChannel.tsx), so the file name always stays visible; hover for the full path
• The file's +adds −dels (a zero count is hidden)
• Previous change / Next change (▲ / ▼)
• Previous file / Next file (◀ / ▶) around an n/m position

The pane bar above it carries Split view / Unified view, Soft wrap (unified view only — on by default, so long lines wrap instead of scrolling sideways), and Open in a tab.

Esc returns to the Changes list with the file you came from focused, so you can review with the keyboard alone: Enter on a file, read, Esc, ↓, Enter.

Keyboard

With the diff focused:

Caps Lock doesn't change what the keys do. The same j / k / ] / [ / Shift+J / Shift+K keys work in a full diff tab.

Live refresh

An open diff re-reads the file every few seconds, so it keeps up while an agent is still editing — even when an edit leaves the +/- counts unchanged. Your scroll position is kept, and a brief Updated note marks each refresh. When you switch files, the previous diff stays on screen under a thin progress bar until the next one loads.

If a read fails, the pane says "Couldn't read the diff — …" with Retry, rather than claiming the file has no changes. The error clears when you move to another file.

View Modes

• Unified view — Traditional single-column diff with +/- prefixes and line numbers on both sides
• Split view — Side-by-side comparison with synchronized scrolling. Deletions on the left, additions on the right.

New diffs open in the layout set under Settings → Git → Diffs → Diff layout. Switching layout in a diff also makes it the remembered default — the same setting the pull request Code tab uses.

The Diff Tab

A full diff tab in the main area has its own toolbar: the file path with an Edit file button, Split view / Unified view, previous / next change, previous / next file with an X/Y position (e.g., 3/7), Focus mode, and Close diff. It persists while you switch between files.

Focus Mode

Toggle focus mode to review one section at a time. When enabled, section buttons appear — Staged, Unstaged, All — and file navigation steps only through the files in the selected section.

Hunk Navigation

Previous / next change jump between change hunks (the @@ markers in a diff), with smooth scrolling between them.

Conflict Marker Highlighting

When viewing files with merge conflicts, the diff viewer highlights conflict markers with distinct styling:

This works in both unified and split views.
