How do you stop AI coding tools from overwriting codes?

When vibe coding, asking AI to add a new feature can sometimes change code that was already working

For developers building with AI, what workflow do you use to keep changes safe?

Do you create a separate branch for each feature, review diffs before accepting changes, or use another approach?
