Usage

Start a review with /diff. By default, this reviews your current unstaged changes:

/diff

Review staged changes with --cached:

/diff --cached

Review a branch or commit range by passing any git diff arguments after /diff:

/diff main...HEAD

/diff <git-diff-args> is passed through to git diff, so these examples are equivalent to running git diff, git diff --cached, and git diff main...HEAD locally before opening the review UI.

Staged vs. unstaged changes

• /diff shows unstaged working-tree changes only.
• /diff --cached shows staged changes only.
• If you have both staged and unstaged edits, run both commands separately to review each set.
• To review everything relative to a base branch, use a range such as /diff main...HEAD.

Features

• /diff reviews the current unstaged git diff
• /diff --cached reviews staged changes
• /diff main...HEAD reviews changes on the current branch relative to main
• /diff <git-diff-args> passes arguments through to git diff
• j/k or arrow keys to move
• g/G to jump to the top or bottom of the diff
• ctrl-u / ctrl-d to move up/down by half a page
• t toggles inline comments/explanations
• v toggles the diff between unified and side-by-side split rendering
• ? toggles an AI-generated explanation for the current hunk
• / searches diff lines; n/N moves between matches while a search is active
• J/K to extend a highlighted selection into a comment range
• esc clears the active selection, or exits review when no selection is active
• n/p to jump hunks
• c to add or edit a comment for the current line or selected range
• C to add or edit an overall diff comment
• x to delete a comment for the current line or selected range
• Enter to submit comments back to pi
• Comments are cached per session and restored when reopening the same diff
• q to exit
