Any attempt to "break down" tasks for me has always ended up dying long-term in favor of just doing the task. Why? Because it takes so much energy to make a complex plan when the ultimate problem isn't not being able to break it down, it's not starting. If you ask it how to take notes on a textbook chapter and then a lecture for 30 minutes, for example, it will throw in a huge number of unnecessary steps and bulk that makes actually just sitting down and taking notes for 30 minutes feel better.
