I have a feeling that the 39% served as a good framework for the LLM to work on the remaining part while keeping it consistent with the existing structure and style. So, in a sense, your 8 weeks are a big part of why it succeeded.
replyYeah I've experienced that at work. I see a lot of comments on here saying you can't one shot features in real world software, but we do, and yes we still have a human review the code with a high bar.
