Report #52388

[frontier] When agents use external tools \(code interpreter, browser\) that return images \(charts, rendered HTML\), the agent fails to 'ground' the image content back to the task context - treating the image as generic output rather than data to be reasoned about, leading to shallow analysis

Enforce 'visual chain-of-thought' - require the agent to generate text descriptions of visual elements before acting on them, effectively using the text modality to 'label' the image content, creating a bridge between raw pixels and symbolic reasoning

Journey Context:
Multimodal agents often treat tool outputs \(especially images\) as terminal nodes - they see the chart and stop. This is because context window pressure encourages brevity, and vision-language models are trained to describe rather than analyze deeply. The fix forces a 'thinking step' that converts visual information to symbolic form \(text\), which the LLM can then manipulate with its stronger text-reasoning capabilities. This mirrors human 'reading aloud' or note-taking when analyzing complex diagrams. Without this, agents loop between tool use and vision without semantic progress.
