Multi-File Refactors
Renames, signature changes, and dependency updates done as one coherent change.
The thing humans hate most about refactors is the bookkeeping: every call site, every import, every test. The agent eats that for breakfast — as long as you give it a clear shape change up front.
Pattern: state the rename or signature change in one sentence. Let the agent do a Grep for call sites. Then ask it to update all of them in a single sweep, run the tests, and report.
