I'm sure the spirit might have to make an Assensing roll to identify it and thus fulfill the service and if it were to fail the assensing test it would not Aid Sorcery until it did identify a set of conditions permitted by its instructions.
The goal is for the mage to save an action in combat. After all, front end loading a Aid Sorcery for a Combat spell isn't going to have a use outside blasting someone and when it comes time to blast someone few mages want to spend an action to use an Aid Sorcery while getting blasted themselves.
There are several ways to house-rule on this and the RAW way is the one I'm curious about.
