Git Review

Git Review

Interactive annotation-based code review using editor overlays.

Activation Triggers

• "git review", "review changes", "review my changes"
• "annotate changes", "interactive review"
• "review diff", "annotate diff"

How It Works

1. Script generates a cleaned-up diff file (friendly headers, no technical noise)
2. Opens in $EDITOR via agterm overlay, tmux popup, kitty overlay, or wezterm split-pane
3. User adds annotations (comments, change requests) directly in the file
4. Script returns user's annotations as a git diff
5. Claude reads annotations, fixes code in the real repo
6. Script regenerates fresh diff (reflecting fixes), opens again
7. Loop until user closes editor without changes

Workflow

Step 1: Run the script

${CLAUDE_PLUGIN_ROOT}/skills/git-review/scripts/git-review.py [base_ref]

• No arguments: auto-detects uncommitted changes or branch vs default branch
• With argument: diffs against the specified ref (branch, tag, commit, HEAD~3)

Step 2: Process annotations

If the script produces output (stdout), the user made annotations. The output is a git diff showing what the user added/changed in the review file.

Read the diff carefully:

• Added lines (+): user's annotations, comments, or change requests
• Removed lines (-): user wants something removed or changed
• Modified lines (- then +): user replaced text to show desired change

Each annotation is in context — the surrounding === file headers and diff content show which file and code area the annotation refers to.

Step 3: Plan changes

Enter plan mode (EnterPlanMode) to analyze annotations and design the fix approach:

• list each annotation and which file/code area it refers to
• describe the planned changes for each annotation
• get user approval before modifying any code

Step 4: Address annotations

After plan approval, fix the actual source code in the real repository. Each annotation is a directive — treat it as a code review comment that must be addressed.

Step 5: Loop

After fixing code, run the script again. It regenerates a fresh diff reflecting the fixes and opens the editor. The user can:

• Add more annotations → go back to step 2 (plan + fix again)
• Close without changes → review complete (no stdout output)

Step 6: Done

When the script produces no output, the review is complete. Inform the user.

Script Arguments

Example Session

User: "review my changes"
→ run: git-review.py
→ editor opens with cleaned diff
→ user adds "this should validate input" next to a handler
→ user closes editor
→ stdout shows the annotation
→ enter plan mode: "annotation requests input validation in handler.go, plan: add validate() call"
→ user approves plan
→ Claude adds input validation to the handler
→ run: git-review.py (again)
→ editor opens with updated diff (validation now visible)
→ user closes without changes
→ no stdout → review complete
→ "review complete, all annotations addressed"

Requirements

• agterm, tmux, kitty, or wezterm terminal (for editor overlay)
• $EDITOR set (defaults to vi)
• git
• agterm users: needs agtermctl on PATH (bundled with agterm); no extra config; pane-scoped overlays need agterm 0.20.0+
• kitty users: kitty.conf must have allow_remote_control yes and listen_on unix:/tmp/kitty-$KITTY_PID
