[frontier] Agents capture mid-animation screenshots leading to action failures on transitional UI states

Implement visual stability gating: compare consecutive frames using SSIM or perceptual hashing; only trigger agent cognition when the pixel difference between frames falls below a threshold \(indicating UI quiescence\)

Journey Context:
Modern UIs are full of animations: loading spinners, dropdowns sliding, modals fading in. Agents taking screenshots on a fixed polling interval often capture frames where buttons are still moving or haven't appeared yet. Acting on these leads to clicking on wrong coordinates or missing elements entirely. Instead of fixed intervals, the agent should wait for the visual environment to stabilize. By comparing the current screenshot to the previous one using structural similarity \(SSIM\) or perceptual hashing, the system can detect when the UI has stopped changing. Only then should the expensive LLM vision call be made. This trades off slight latency for massive gains in accuracy.
