Report #57686

[frontier] Agent loses task context when alternating between text reasoning and image analysis within the same step

Enforce 'modal epochs': batch all visual operations into perception phases separated by text reasoning phases. Use explicit 'bridging prompts' that force text summarization of visual findings before any action generation. Never interleave vision and text generation within a single model call.

Journey Context:
Anthropic's Computer Use system cards reveal that vision tokens compress attention differently than text, creating 'attention residue' where the model fixates on prior visual features when it should reason textually. Simple batching isn't enough—the bridge prompt acts as a modality translator, converting visual embeddings into semantic text tokens that play nicely with the text-only action parser. Alternatives like mixed-modal JSON output fail because the model hallucinates visual details when forced to generate text and perceive simultaneously.
