What do I do when the AI gets stuck, loops, or breaks things it already built?

The 'fix this, break that' loop is the number one vibe-coding frustration, and it is usually a context problem: the session's memory is full and the AI is patching symptoms. The escape moves are mechanical: stop, start a completely fresh chat, describe the bug and what you have tried, ask for the root cause rather than a fix, and paste actual error messages from the browser console or logs. Combine that with a checkpoint or Git commit before every AI change so a bad fix costs you minutes, not days.
