[frontier] Multimodal agents drown in irrelevant visual details during long chart or document reasoning tasks

Use a hierarchical agent: a manager keeps distilled text context while workers operate on scoped single-image views with zoom-in tools.

Journey Context:
Advanced chart or document questions require both fine-grained perception of small marks and multi-step reasoning across several subplots. Sending every high-resolution crop into a flat transcript makes the signal-to-noise ratio collapse as the trajectory grows. HIERVA shows a better architecture: a high-level manager generates plans and stores only distilled, structured results; specialized workers receive a scoped local context containing a single image view and a zoom-in tool to crop relevant regions. This prevents the monotonic growth of redundant visual evidence and intermediate text. The same pattern applies to any long-horizon multimodal task—UI workflows, scientific figures, multi-page forms—where global context and local detail must be managed separately.
