Tying a knot, lighting a candle, making someone yawn, dimming a light, nudging a box -- this is already answered (though frankly, I think even paying 1ST point is a bit high...) Damage is limited to 0 or 1 point. Again, already answered.

You tell him that a minor effect only costs 1 ST point, and that he can't put more than 1 ST point into it.

You negotiate -- the player proposes a minor effect that he wants to try, and the GM either approves, disapproves, or suggests something slightly different.

The same way you do any other spell.
