Perhaps the experts have decided that, for this specific instance, the thing we need to do is ad-hoc and throwaway, and is simply not worth paying the extra cost to make it tasteful.
I'm sorry but "extensive documentation, scalable, high test coverage, perfect code style" seems to me to be the opposite of throwaway.
It sounds like the kind of thing people will think surely must be very important and in use, because why go through all those hoops instead of doing a quick hack?
But I guess we can just throw AI at the maintenance burden anyways..
How can a bash one-liner be more expensive to build than a full-blown CLI tool with the maintenance burden that comes with it?
