Report #50769

[frontier] Agents default to single modality throughout task, wasting money on vision API calls for text-heavy tasks or failing on visual-spatial reasoning that requires images

Deploy Dynamic Modality Switching Heuristics: Route sub-tasks based on content type - DOM/text extraction for reading, structured data, or code; Vision API for spatial reasoning, layout understanding, or visual verification; Maintain confidence thresholds \(e.g., switch to vision if DOM selector confidence < 0.8 or task involves 'find icon', 'verify color'\)

Journey Context:
Static modality assignment wastes tokens on vision where DOM suffices, or fails on visual tasks with text-only; dynamic routing optimizes cost/accuracy tradeoff per sub-task. OpenAI's CUA and LangChain's multi-modal routers implement variations of this cost-aware routing.
