Reducing codebase cognitive debt through... quizzes?

Like many, when I'm building with coding agents, one of the "worst" problems is the codebase feels like it is often evolving faster than I can keep up with it. This cognitive debt builds up quietly - nothing is broken, but you gradually have this feeling of not being totally on top of what is going on. One remarkably effective technique I stumbled on is asking the agent to quiz you on the code base. A simple prompt like: hi, please quiz me about this codebase. i want 5 questions of increasing difficulty - then explain to me at the end what i got wrong about my understanding. use the askuserquestiontool Produces a simple quiz you can answer. The best bit is chatting to the agent about the ones you got wrong. It has the context of what you thought versus what the code actually does, so it can explain the gap far better than it could if you'd just asked it to describe that part of the codebase itself. You can of course use this for non code tasks too, e.g. complex spreadsheets or…
