This only works if the software is still crafted by a human and merely using AI as a tool. In that case the use of AI is similar to using editor macros or test-driven development. I don't need to see that process playing out in real time.
It's less clear to me if the software isn't crafted by a human at all, though. In that case I would prefer to see the prompt.
I agree that fully agentic development will change things, but I don't know how. I'm still very much in the human-in-the-loop phase of AI where I want to understand and verify that it's not done anything silly. I care far more about the code that I'm deploying than the prompt that got me there and probably will for a long time. So will my prodsec team.
