Key frames: each decision's starting frame with the click it produced (amber = proposal before binding, red = committed, grey = suppressed), then the screen at each arrival A (green = valid).
You control a game by clicking. You are shown one screenshot. Three balloons of different colors (red, blue, yellow) appear at unknown positions and may drift; they disappear after a short time. Your task: if the yellow balloon is visible, answer with action "click" and the coordinates of the center of the yellow balloon on a 0-1000 grid (x: 0 = left edge, 1000 = right edge; y: 0 = top edge, 1000 = bottom edge). Do not click any other balloon. If no balloons are visible, answer with action "wait". Answer with the JSON object only. [user] Screenshot attached. Click the target's center or wait.
