The secret sauce for me is Beads. Once Beads is setup you make the tasks and refine them and by the end each task is a very detailed prompt. I have Claude ask me clarifying questions, do research for best practices etc

Because of Beads I can have Claude do a code review for serious bugs and issues and sure enough it finds some interesting things I overlooked.

I have also seen my peers in the reverse engineering field make breakthroughs emulating runtimes that have no or limited existing runtimes, all from the ground up mind you.

I think the key is thinking of yourself as an architect / mentor for a capable and promising Junior developer.
