I would like to say I did a massive refactoring on a legacy project only to make separation of concerns by making a DB access layer with multiple backends just so I could test it. I wrote not even a single line of code. It did a fantastic job even abstracting between both databases. I was shocked. It then was a huge PR so I had it redo it in a step by step fashion and maintain the tests passing at each step so I could split it into 5 different pull-requests. This vibe-coded project did the exact opposite, it made it easy and possible to fix a mostly intested and poorly organized project far better. You can use this stuff for good SWE practices too
