Report #29584

[frontier] Agents burn context windows re-analyzing static UI regions across sequential screenshots

Implement perceptual hashing \(pHash\) diffing to mask unchanged regions with transparency metadata, feeding only >5% delta-regions to the VLM

Journey Context:
Naive screenshot loops send full 1080p repeatedly. Simple pixel-diff triggers on spinners. pHash isolates semantic changes while ignoring compression artifacts. Mimics human saccadic memory, unlike basic frame sampling.
