The bidding has gone as shown. It is your bid.

When the opponents interfere, Jacoby is off. Now a cue-bid response by partner shows a hand with good trump support, and a limit raise or better in strength. So partner might have a game forcing hand, but also might have only 11 points.

But he definitely has ♠ support.
You show your minimum hand by bidding 3♠ and he passes.
