[frontier] Multi-modal agents suffer modality amnesia when switching from vision reasoning to text-only API calls, losing spatial context

Maintain 'cross-modal latent anchors' by converting vision embeddings \(CLIP-style\) into persistent text tokens or memory keys that remain active in the context window during text-only phases, preventing the agent from forgetting what it saw when it switches modalities

Journey Context:
When agents alternate between screenshot analysis \(vision\) and API calls/text reasoning \(text\), they often treat these as separate episodes. The text model doesn't 'remember' the screenshot content except through the vision model's text description, which loses spatial relationships and fine details \(e.g., exact position of a slider handle\). When the agent switches back to vision, it may re-analyze the same screenshot redundantly or lose continuity. Instead of relying on text descriptions alone, maintain a 'memory bridge' using multimodal embeddings: \(1\) when processing a screenshot, extract CLIP or similar embeddings for key regions, \(2\) project these into the text model's embedding space or convert to special 'memory tokens' that occupy minimal context, \(3\) during text-only phases, these tokens persist in the context window, acting as 'latent reminders' of spatial layouts and visual features, \(4\) when switching back to vision, use these embeddings to align the new screenshot with previous state \(image registration\). This prevents 'modality amnesia' where the agent effectively starts fresh with each mode switch.
