Do you actually let AI tools refactor multiple files at once?

I have been thanking how people handle larger refactors with AI coding tools. Most of them can work across entire repos pretty easily now. But I still find myself being more cautious when something affects a lot of files at once.

When i am focused on a single feature, everything seems okay but as soon as I start changing shared utilities, hooks, configurations, or moving things between folders​ I ​slow down and become much more careful. At this point I manually review most of​ every step to make sure it's correct.

Lately I have been using Claude Code with wozcode on a TypeScript project. It feels pretty solid for iterative changes, especially when I keep tasks scoped. Still, I do not fully trust massive automated refactors unless the project structure is extremely clean.

I am want to know where other developers stand on this issue. Are you okay with letting these tools manage large repository changes? Or do you ​keep strict control over them?
