I was at an inspection where the inspector could not locate entryway into crawl space. I called the listing agent who called the seller and we found out it was through a closet.
If the agent were mine I would request having them there.

Also, a buyer's agent should be present so that they can hear all of the details first hand from the inspector, and ask any questions they see fit. That way, when you do go back to the sellers with requests, your agent knows everything they need to.
