I think your character is mostly fine, because you're trying to do something adepts are good at (social skills and PER) and then leaning on spells for fighting. Some suggestions:
What tradition are you?
You have too much Agility. You have two agility linked skills - Infiltration and Unarmed Combat. And you're generally going to use unarmed combat for Block, not punching, since your spells are mostly better. You would be much better off dropping your Agility down and having more Intuition and Reaction, both of which are far more useful to you - Intuition especially.
In a oneshot I really just wouldn't bother with Astral Chameleon. It's only really worth it in conjunction with some of the metamagics.
Mind Link is crap. I know, I know, it sounds cool, but it is a terrible, terrible spell and having it makes you a bad person. Just use a commlink. Mind Link is horrible and heavily limited, and it just has so much that can go wrong with it, and it has to be sustained, and arrrgh. I would probably grab Increase Charisma instead; if you cast it and get 4 hits (and the drain is 0 at force 5, so you can do this with no real risk), you get a net +2 even with the sustaining penalty. Also helpful for summoning spirits.
You would benefit enormously, and I mean enormously enormously, from having Restricted Gear for a force 4 power focus. Drop magic from 6 to 5 and go 2 magic/3 adept powers if you have to. +4 to everything is worth it. Also, you really should have a second 5 skill or Spellcasting 6.
Specializing skills at chargen is normally bad but this is a oneshot. Specialize at the very least Spellcasting, Summoning, and Unarmed Combat, and probably Perception too.
Sustaining foci are per school. You have to pick schools for them. The f3 one should be increase reflexes; what did you want with the f2 one?
Depending on how your GM thinks it works, Heightened Concentration (from Digital Grimoire) might be super awesome for you. Or it might suck. Check it out.
