[frontier] Agents wasting tokens and latency using vision models for purely symbolic reasoning or text models for spatial tasks

Implement a modality router that classifies sub-task type \(spatial/visual vs symbolic/textual\) using heuristics or a small classifier model. Route to vision-capable models only for tasks requiring spatial reasoning or OCR; use fast text-only models for logic, calculation, and API calls.

Journey Context:
Using GPT-4V for 'calculate the sum of these numbers' introduces OCR errors and costs 10x more than Haiku; using text-only models to describe visual layouts loses spatial relationships and relative positioning. The orchestrator maintains a 'modality confidence score' and can re-route or escalate. This pattern is emerging in production agents using LangGraph state machines and Microsoft's AutoGen multi-agent patterns to minimize latency and cost.
