I've been experimenting with a lot of these learning skills (see also, e.g., https://github.com/mattpocock/skills/blob/main/skills/produc..., which I think addresses the progress tracking part better than this skill) and they're great for getting simple answers, getting unstuck on exercises, getting some intuition through simulations, etc, but I still feel some more structure is needed for effective self-teaching. Has anyone tried using a hard book as a sort of course structure and asking the LLM to teach you through it? You could of course just read the book, but a lot of advanced subjects don't have great learning materials.
