What on earth does this have to do with it? Roy and Miko's career motivations are irrelevant to their ability to reasonably requisition services from peers and subordinates within their organisation.
The spellcraft skill allows you to identify spells and magic items whose function would not otherwise be obvious to the naked eye. She doesn't need ranks in spellcraft in order to know that various highly-impactful spell-categories exist, any more than Roy needs ranks in such a skill in order to know that Planar Ally and Sending spells do, or any more than someone in our world needs to be an electrical engineer or physics PhD in order to know that telephones and aeroplanes exist.
I am not trying to argue that Miko has an infallible spiritual mandate and/or perfect information about all forms of D&D class mechanics, but I am not going to accept that she is some of kind of drooling idiot backbirth who knows less about the world she inhabits than a 10-year child would know about ours, or spent the last 28 years of her life living under a rock.
