Report #86588

[frontier] Agents lose task continuity when switching between analyzing images and generating text—constraints mentioned before the image are forgotten after vision processing \('modal context collapse'\)

Implement anchored scaffolding—require the agent to output structured reasoning text \(JSON with 'reasoning' and 'next\_action' fields\) between every vision observation, explicitly restating constraints and progress before processing the next image

Journey Context:
Vision models process images into 'soft prompts' that can overwrite previous text context in transformer attention. When an agent looks at a screenshot, the visual tokens \(hundreds of them\) can 'dilute' the memory of instructions like 'do not click submit'. The anchored pattern forces a 'context checkpoint'—after every image analysis, the model must write down what it learned and what constraints still apply. This mirrors 'chain-of-thought' but specifically bridges the modal gap. Implementation: use tool-calling with strict output schemas; the 'analyze\_screen' tool must return structured analysis before 'click\_element' can be called. Alternative: End-to-end vision skipping text reasoning is faster but suffers 3x higher error rates on multi-step tasks.
