How do you stop AI coding tools from rewriting your whole codebase for a tiny bug?

It's honestly hilarious and frustrating at the same time. I asked my coding assistant to fix a tiny typo in a button text yesterday and it came back with a brand new component architecture split files and a custom state hook. It felt like dealing with an overly enthusiastic junior developer high on espresso who just wants to show off everything they can do. I just wanted a one line string change!

Have you found a reliable way to keep these agents lazy and focused strictly on the exact line you point to?
