Review the Change That Was Never Requested

An agent can solve the named problem and also change behavior you meant to preserve. Read the diff with both questions in mind.

For a formatting fix, ask Claude Code to identify any changed calculations, dependencies or public interfaces. Inspect those claims against the files rather than accepting “no behavior change” as evidence. A small before-and-after fixture can reveal altered sorting or rounded amounts.

If an unrelated repair is useful, give it its own reviewable change with a reason. That makes the current fix easier to understand and the additional work easier to reverse. The practical benefit is a narrower decision for the reviewer: they can assess the original request without discovering a second project hidden inside it.
