I am curious in your experience how often the LLM must also update the tests. I find that if LLMs write tests after the implementation exists, they are either extremely brittle because they are coupled to the implementation, or they cover little of value because they mock everything to the point of testing nothing.
I question your assertion that more commits and releases per week is more productivity. There could be unexpected effects from your commits that create more work for you or for others and that could be hard to quantify.
Doing bad things faster might feel more productive to you, but it doesn’t mean that you are delivering more value. You might be, but the metrics you have shared to not prove that.
I instruct the LLM to follow TDD practices in certain areas, but otherwise prioritize integration style tests at the edges.
