alt Hacker Newsone thing I probably didn't mention is we do the program design having already done an in-depth codebase research, with current patterns and architecture surfaced - that actually seeds every step of the flow including even the product part -
but yes if you're working in very small slices then I think it's very feasible to skip program design and just review the code as you go, and resteer live. I do this all the time for tasks that are too big for a oneshot but on the smaller side overall.
Do you think that the program design adds a lot on top of pointing out the current patterns?
I might be anchored by working with humans, but if I saw a plan for humans that included function signatures and what calls what I would say that is way too detailed. As a result I don't put it in my plans for AI either.
