Teams that review diffs every day.

I hand it the dull tickets in the morning and review the diffs after lunch. It has not once changed something I did not see.

Our reviewers stopped dreading agent pull requests. The description tells them what changed and why before they read a line.

We are four people. Hearth writes the tests we never had time for, and it asks before it does anything strange.

We run it in CI for formatting and snapshot fixes only. The rules file makes that boundary boring, which is exactly what we wanted.

I use explain more than fix. Asking how the billing worker works and getting file and line answers saves me an hour a week.

The permission prompt sold our security lead. It says exactly what will run, where, and why.
