Git & diff viewer

Keep an eye on what Claude is doing to your working tree without leaving the chat: a git panel for status and history, and a diff viewer that can compare almost anything against almost anything.

The git widget

Press Alt+G to open the git panel for the current session's repository. The header shows the branch as a pill, with ahead/behind arrows (↑2 ↓1) when your branch has diverged from its upstream — the same branch also appears in the session status bar.

The status view groups uncommitted work into Staged Changes, Changes, and Untracked Files, each with a count. Every file gets a colored status letter (M modified, A added, D deleted, R renamed, C copied, ? untracked) and +/- line stats. Click a tracked file to see its diff inline — hunk by hunk, right in the panel — with a back button to return and a columns button to reopen the same diff side by side in the full diff viewer.

Two header buttons switch context: the clock opens commit history (twenty commits at a time, with load more), and the refresh button re-reads status. Click a commit to open its detail view: full message (expandable when long), author, relative time, and the file list with per-file +/- stats — click any file to open that commit's diff in the diff viewer.

Right-clicking a changed file gets you the usual file actions (the same menu as chat file pills), and the widget floats, docks as a sidebar, or promotes to a tab like everything else.

Read-only by design

The git widget shows state; it doesn't stage, commit, or push. Ask Claude to run the git commands, or drop into the embedded terminal and do it yourself.

The diff viewer

The diff viewer is a dedicated widget for comparing two versions of a file — or a set of files — with two rendering modes you can toggle at any time: Split (side-by-side columns, perfectly line-aligned) and Unified (classic single-column). A wrap toggle handles long lines, unchanged regions collapse into "N unchanged lines" expanders, and when it holds multiple files, arrows step through them. On the keyboard, J / N jump to the next hunk and K / P to the previous one.

You'll land in it from all over the app:

• Edit tool blocks in the chat — every edit Claude makes renders as a diff pill with a Side-by-side button.
• Turn summary bar file pills — tap for the diff, long-press for compare presets.
• The git widget — the side-by-side button on a working-tree diff, or any file inside a commit's detail view.
• The file explorer — Compare… on any file, or Select for Compare on one file followed by Compare with… on another for a quick two-file diff.
• The Journal — history explorer entries have Open in diff tool.
• The file preview's History tab — a per-file timeline of Shadow Git snapshots.

The history bar

When the compared file has Shadow Git history, a bar across the top of the diff turns it into a time machine: From and To pickers select any two recorded snapshots, arrow buttons step to older or newer ones, and pivot shortcuts jump to the common questions — vs HEAD (working tree against your last real git commit), vs Working (a snapshot against the file on disk right now), or Pick… to open the Compare Wizard.

The Compare Wizard

Compare… (from the file explorer, a file pill's long-press menu, or the history bar's Pick…) opens a small wizard: choose what to compare the file against, then pick the exact version. Five sources:

Source	What you're comparing against
Shadow History	Versions recorded from Claude sessions — every turn that touched the file
Git History	Previous git commits that touched the file
Git Branches	The same file on another branch
Working Changes	HEAD vs working tree, or HEAD vs staged
Another File	Any other file in the project (searchable picker)

The wizard is fully keyboard-navigable — arrows to move, Enter to select, Esc to back out.
