I tend to think people like this are just looking for an excuse not to work. My approach is to either facilitate them or force them to do more work. If I decide to facilitate their not doing work, I would say "Yeah, I think there are docs for this. I'm in the middle of something, but give me an hour or so and I'll email you the link." Then, I'll forget about it. If they really need to know they'll come back and ask again. If I decide to disincentivize them by making it more work for them to ask me for work I'd go along the lines of - "That's great feedback. Why don't you take notes of all the issues you have with the wiki while you're working on your thing. When you're done, update the wiki so the next person to use it can benefit from what you find. Thanks."
