Report #83459

[frontier] Agents thrash between text and vision modalities mid-task, causing state inconsistency

Enforce modality persistence windows: once an agent enters 'vision mode' for a subtask, it must complete a minimum number of vision-grounded actions \(or reach a specific visual termination condition like 'wait for loading spinner to disappear'\) before switching back to text-only reasoning.

Journey Context:
Frequent switching between analyzing screenshots and text reasoning causes the agent to lose track of visual state, repeat actions, or hallucinate changes. Each modality switch incurs a 'context-switching penalty' where the model forgets spatial relationships. The fix is treating vision as a 'transaction': batch all visual observations and actions together, commit the state change \(verify the visual outcome\), then return to text mode. This prevents the 'oscillation' where the agent alternates between screenshot analysis and text planning without making progress.
