Model regression on simple toggle

I ran into a situation where an AI model in Cursor accidentally created a major regression in my project, and I’m trying to understand whether there’s a better workflow for catching or reversing these issues when they come up.

I had previously asked the model to disable a feature in my code. At the time, everything seemed fine, so I moved on. Later, I noticed that all the buttons on my site had stopped working, none of them were clickable anymore.

I asked the model to help debug the issue, but instead of recognizing that the disabled feature was the cause, it spent over 30 minutes trying to fix. I started new threads & tried different models, but they all kept trying to repair the UI unsuccessfully instead of checking whether a previously disabled feature was responsible.

Eventually, I switched to Opus 4.7 with max context, and that model finally realized the root cause: the feature I had turned off earlier was exactly what controlled the button interactivity. It re‑enabled it, and everything immediately worked again.

I ended up burning a lot of tokens & time just to get back to a simple toggle. I also had the models inspect diffs and scan the repo, but they still didn’t connect the dots until the very end.

Has anyone found a better workflow for situations like this?

Is there a recommended way to have Cursor track or summarize “risky” changes it makes?

are there better prompt patterns for asking Cursor to audit its own previous edits?

Are there tools or settings in Cursor that help prevent this kind of regression or help models reason about earlier changes more reliably?

Any suggestions appreciated!
