Use focus mode

This guide shows you how to use focus mode for distraction-free PR review.

Focus mode is an ephemeral, minimalist UI for PR review. It strips away the sidebar, navigation, and all non-essential chrome to give you a clean, full-screen diff viewer.

It’s built for deep review sessions where you need to concentrate on the code without interruptions — large PRs, security-sensitive changes, or any review where the surrounding shell competes for your attention.

  1. Open any PR
  2. Click the focus mode toggle in the PR header (or use the keyboard shortcut)
  3. The sidebar and title bar collapse, leaving only the diff viewer
  • Full-width diff viewer — the diff takes the entire window, so wide hunks and side-by-side views have room to breathe.
  • Keyboard navigation — move between files and changes without reaching for the mouse. See Keyboard shortcuts for the full map.
  • Inline comments — leave comments directly on the diff, exactly as you would in the full layout.
  • File list — a collapsible file tree for quick jumps between files.

Focus mode is ephemeral — it’s a UI toggle, not a separate review session. Switching in or out never loses work:

  • Your viewed-file progress carries across the toggle.
  • Draft comments are preserved when you exit and re-enter.
  • The PR’s review state (approvals, requested changes) is unaffected — focus mode changes what you see, not the review itself.

Use the full layout when you want to stay aware of other agents’ activity while you review; switch to focus mode when a change deserves your undivided attention.

Press Escape or click the exit button to return to the normal shell layout.

  • Security-sensitive code that requires deep attention
