Cmd. /diff

Key takeaways

/diff shows the Git diff, including files Git is not tracking yet, so you can inspect Codex edits before committing or testing.
Run it before /review to know the exact behavioral surface, and after applying a subagent result before merging.
/diff is not a test; run the relevant verification command after reviewing changes.
In dirty worktrees, separate your own changes from Codex changes before judging the result.
