An Agent as an NPC (Secrets of the Ancients Spoilers)

I just finished Marc MIller's Agent of the Imperium book (great by the way) and since I will be running Secrets of the Ancients in the future I had the idea to replace Galen in Chapter Eight with either Jonathan from the book or some other Agent program designed for interrogation. This does seem like an important enough situation that an Agent would be activated for.

I was wondering if there were any specific rules or stats for using this program or if I should just use this as a GM Fiat. Also what sort of things should I consider if I decide to use an Agent in this situation. Just looking for general advice on this topic.
