It reads more like a CONOPS or a software architecture document, but its not detailed enough from a high level perspective, and too detailed at a low level perspective (ie. it has implementation details in a few places you wouldnt expect in a higher level design doc).
In that light, I'm not sure who the audience would be in a corporate environment. Is it for architects, other developers, or yourself?
They suck at multi-threading, they suck at maintaining a coherent goal through multiple files, they suck at basic math (claude could NOT figure out how to get the hypotenuse of a triangle given angle and side lengths...).
Sometimes I mess around with prompts just to see what I get back, more often than not, it's mostly a waste of time. God forbid you use it to refactor anything.
