I agree with HawVie - you're just describing someone who is smart but doesn't work well with others. As RroRobie pointed out, the key is that a wolf generates exceptional value (the same paragraph also says they do what's best for the future of the company), but someone who skips documentation and test cases isn't generating exceptional value and isn't doing what's best for the future of the company. They're just lazy and egocentric. A "wolf", as you're trying to describe (think Hawkeye from MASH), would break the rules that didn't impact the work they're doing but the examples you gave here are all directly related to the work.

Also, if a wolf was such a talented engineer, why would they mock "the system"? Wouldn't they want to help improve it? This goes back to what HawVie said - these people don't have the balls to do it (they were referring to "the balls to start their own company" but it applies here too). These are just engineers who are a little smarter than their peers but want to create the illusion they're a *lot* smarter (or maybe they're not smarter, they just seem more productive because they skirt responsibilities and because their work is largely a mystery to others). Mocking "the system" makes them look smart and if they tried to improve the system and failed, the ruse would be up.

This description definitely matches a lot of engineers but it's not a kind of person we should be praising - at least not for their work ethic, maybe they're good at something else :-/
