Accept or reject the edits made by Claude Code, right inside your editor — with
an inline diff per hunk and per-file review. When Claude Code changes your
files, this extension shows the changes in place (green for added, red for
removed) and lets you approve or discard them without leaving the IDE.
Features
Inline diff in the editor. Changed lines are shown in place — red
(strikethrough) for the previous version, green for the new one.
Word-level highlighting. Inside a modified line, only the part that
actually changed gets the strong highlight, so you see exactly what moved.
Accept / reject per hunk. Clickable actions appear above each changed
block; resolve one piece at a time.
Accept / reject per file. Inline buttons on each item in the panel, plus
buttons in the editor title bar for the current file.
Accept / reject everything. Global buttons at the top of the panel to
confirm or discard changes across all files at once.
Automatic review. As soon as a file changes on disk (for example, after
a Claude Code edit), the review opens on its own. Can be turned off.
Changed-files panel. A "Modified (Claude Diff)" view in the Explorer
lists every changed file with a "pending" or "in review" status.
Smart baseline. After you accept a change, the approved state becomes the
new reference. So if you accept new code and later remove it, the removal
shows up for review instead of silently disappearing.
How it works
Because Claude Code writes changes straight to disk, the extension rebuilds the
"before" version from git (the last commit, HEAD) and renders the diff in
place. Accepting keeps the new lines; rejecting restores the previous ones.
Line endings (CRLF/LF) are normalized only for the comparison, so a file with
different line endings does not show up as fully changed; the original ending is
preserved on save.
The inline accept/reject actions are rendered as CodeLens (clickable text above
each block) rather than a floating overlay, because overlay widgets rely on
editor-internal APIs that are not available to extensions.
Requirements
Visual Studio Code
git installed and on your PATH
The project you review must be a git repository with at least one commit
Getting started
Open a project that is a git repository.
Recommended: turn off Auto Save (File > Auto Save) while reviewing.
Run Claude Code and ask for a code change.
The review opens in the editor with the green/red diff and the
Accept/Reject actions. The "Modified (Claude Diff)" panel in the Explorer
lists the changed files.
You can also start a review manually: open a changed file and run
Claude Diff: Review current file from the Command Palette (Ctrl+Shift+P).
Settings
claudeDiff.autoReview (boolean, default true) — open the review
automatically when a file changes outside the editor.
Commands
Claude Diff: Review current file
Claude Diff: Accept all / Reject all (current file)
Confirm all / Cancel all changes (all files, from the panel)
Confirm / Cancel file changes (per item, from the panel)
Claude Diff: Reset baseline to HEAD — compare against the last commit
again if the baseline gets out of sync (e.g. after a commit, checkout or pull
done outside the extension).
Notes and limitations
Keep VS Code Auto Save off while reviewing. The review temporarily
reinserts the removed lines into the buffer, so autosaving mid-review could
write that intermediate state to disk. The final, resolved content is saved
when the review completes.
The per-file baseline is stored in the workspace state and persists between
sessions, so it grows over time in long-lived workspaces.
