I'm listing requirements for a job position within a company and one of the duties of the position in question is drawing attention to unclear customer requests, and the need for their clarification. I'm not sure how I would put this in words, and this is the best I could come up with: (comes after a list of other duties of the position)
If the request is vague, to indicate that it needs to be clarified.
So it is not that he directly asks for a clarification of the request, he is only supposed to draw attention to that fact, e.g to someone who is supposed to actually seek for a clarification of the request. The verb "warn" is a possible alternative to "indicate" for what I want to say, but I'm not sure it would sound good in this sentence. Hope someone will provide me with a better phrasing for what I want to say here.
