Report #94371

[frontier] High-resolution screenshots exhaust context window budgets, leaving insufficient tokens for reasoning history and tool definitions

Implement ROI-based adaptive tiling—send a low-resolution 'context' screenshot of the full viewport plus high-resolution 'detail' tiles only for Regions of Interest identified by the previous step's bounding boxes or OCR confidence maps

Journey Context:
Vision models charge tokens per tile \(OpenAI: 512x512 tiles; Anthropic: varying by resolution\). A 4K screenshot can consume 4,000\+ tokens, leaving only 4k for history in an 8k window. The naive approach is to always use 'low' detail, but then small text becomes unreadable. The frontier pattern is 'foveal vision': maintain a low-res global map for navigation, and dynamically request high-res crops of specific elements \(buttons, input fields\) when interacting with them. This requires the agent to output bounding boxes in one step, then consume high-res crops in the next.
