all of the stuff in blue is what you should worry about. The code above is an example of what I did for my Real Warhammer mod.
agent diplomat 0 requires factions { insert faction or culture here, }: This basically just means that the factions in the braces{} can recruit diplomats. Always seperate with a comma and then a space.
agent_limit diplomat 2: This his how many diplomats the building allows to be built at a time.
btw, you edit the "export_descr_buildings.txt"
