I have to draw a very sharp line in generating these kinds of tools, I treat them as single use throwaway things and do my best to never have anyone besides myself even see the tools themselves (e.g. reviewing some calculation results). Else I fully expect to get saddled with turning a temporary thing for a very narrow problem into something production ready.
