Well, he came on his own initiative to get Madoka in episode 6, and told Kyoko that Mami had died so the city was available. But beyond stuff like that, he doesn't really give explanations or instructions unless he's specifically prompted. He does mention that Sayaka isn't listening to his advice, so he might be able to give more than the basics, but has no one willing to listen, or that needs the instructions. Really, Kyubei acts as an incubator, a catalyst, not as an active player.
He does mention that his people (or his creators, or the ones who want this energy to stave off the heat death of the universe) do not have emotions. That's why they needed a species that have emotions, like humans, to use magic for them and supply the required energy. So, if one of the bases we are using for deciding that Kyubei is a construct is his lack of emotion, than his entire species are constructs. Which isn't completely impossible, though they could just as easily be beings that 'run' purely on logic, like what the Vulcans wanted to be. (Now that is a scary thought.)
