Report #55135
[frontier] Agents waste 50%\+ of context window on low-ROI screenshot regions
Implement dynamic viewport partitioning that samples UI chrome at 256px but document content at native resolution, using foveated rendering centered on action targets
Journey Context:
Anthropic's Computer Use beta revealed that full-page screenshots at 1920x1080 consume ~4k tokens vs ~300 tokens for text; leading agents now use 'foveated rendering' strategies borrowed from VR—high fidelity on action targets, blur on static chrome. The trap is uniform downsampling which destroys text legibility. The fix requires maintaining a 'visual attention map' that tracks which viewport regions contain interactive elements vs static templates.
