Report #77912

[frontier] Agents fail when tool outputs \(textual API responses\) must be verified against visual UI state, or when visual changes must be translated into structured tool inputs, due to 'modality silos'

Explicit cross-modal translation layers: deploy intermediate processing modules that convert visual observations into structured text representations for tool consumption \(e.g., 'extract table from screenshot to CSV'\) and vice versa, using specialized small models rather than expecting the LLM to do this implicitly

Journey Context:
Agents with tool use \(APIs \+ vision\) fail when the tool returns data needing visual verification. Example: an API creates a calendar event, but the agent must verify it appeared on the UI calendar view. The 2025 pattern is building 'modal bridges': specialized small models or code modules that translate between screenshot regions and structured data \(JSON/CSV\). This prevents the VLM from hallucinating table structure when reading images, or from generating invalid tool parameters from visual observations. The key is explicit typed interfaces between vision and text modalities.
