Spirit Skills as services Options

[Daedelus]

We recently came across a situation that I need some feedback on. I alloed in the session with the caveat that it may change before our meeting next week. While I appreciate and welcome all feedback, I would like to hear from a developer as to thier intent at the time of design.

A new character recently came into our game as a conjurer. Last night he summoned a force 7 guardian spirit and gave it the command to provide counterspelling to the group as an extended service. The guardian spirit has the counterspelling skill.

The question is if players are allowed to have spirits use skills on thier behalf as a service? The rules are vague as to what constitutes a non-magical service. They imply that skills can be used because combat requires the use of skills and is a legitimate service. Thank you ahead of time for any help you can provide on this matter.
