Seems like something fixable with a simple two step process. Ask it the thing. Then ask it to summarise the answer in simpler terms. More tokens and time aside that would check both boxes

pretty much what I do, better yet ask it to boil it down in visuals in a simple webpage if it's a very large project

Should be a harness feature actually.
