My observation has been that there are a lot of personal styles to engaging with the LLMs that work, and "hold the hand" vs "in-depth plan" vs "combination" doesn't really matter. There is some minimum level of engagement required for non-trivial tasks, and whether that engagement comes mid-development, at the early design phase, or after isn't really that big of a deal. Eg; "Just enough planning" is a fine way of approaching the problem if you're going to be in the loop once the implementation starts.
