Makes me wonder if the LLM, out of the box would go one way or another. I am big fan of services, without the micro part and always guide my model in that direction.
Quality mindset should always exist, so should quality checkpoints.
To mature your system and practices, your code generator, code reviewer and quality checker, shouldn't be the same (people or agents)
Do you save these "prompts" so you can improve, and in turn improve the code. to me Spec Driven Development is more than a spec to generate code, structured or not.
