I want to take a big exception to and put an emphasized quote mark on the word “bad”. I have recently managed to have Windsurf writing 99% of my code. Some code got pushed back. I was expecting that as I was pushing the boundary. What surprised me was, however, the codes got push backs were not bad code, but code that stepped on existing, some unspoken, “conventions”. In a legacy system, many conventions were established for good reasons, but out lived their goodness and got stuck. We need to have x% of the code base that is actively worked replaced every year just to un-stuck ourselves, agent or not.
