The velocity problem is real. AI makes it easy to add things faster than you can understand what you added. The intentionality has to come before you prompt, not after you review.
You can ask the agent to make 10 different solutions in the time it takes you to make 0.5.
Then you review them based on whatever criteria you feel is right and either throw them all away and do it yourself (maybe with inspiration from the other solutions) or pick one to progress further.
