I agree with this, I like spec-driven-development tooling partially for this reason. That being said, what I’ve found is often that I don’t include enough of the “why” in my prompt artifacts. The “what” and “how” are pretty well covered but sometimes I find myself looking back at them thinking “Why did I do this?” I’ve started including it but it does sometimes feel weird because I feel like “Why would the LLM ‘care’ about this story?”
