Report #91700

[frontier] Agents get stuck in infinite screenshot loops when visual state doesn't change during loading or waiting states

Implement adaptive frame sampling based on DOM mutation density and pixel entropy, switching to DOM-based state extraction when visual delta falls below epsilon for static periods

Journey Context:
Current agents sample screenshots at fixed intervals \(every 2 seconds or per action\), missing brief error messages or loading states while wasting tokens on idle screens. The frontier pattern is 'entropy-adaptive vision': use lightweight DOM mutation observers or perceptual hashing \(pHash\) to detect visual volatility. When entropy is high \(animations, rapid DOM changes\), sample at high frequency; when low, suppress screenshots and rely on DOM state with periodic 'heartbeat' visual verification. This mimics human saccadic vision. Common mistake: uniform sampling rates causing either missed transient states or bankruptcy from redundant frames. Alternative: video encoding \(too complex for current LLM APIs\). Right call: entropy-triggered keyframe sampling.
