[frontier] Vision inputs silently override deliberative reasoning in multimodal agents

For consequential decisions that use screenshots, first generate a structured text caption or accessibility summary, run a text-only reasoning pass over it, and reconcile with visual evidence before acting. Do not let the vision branch emit the final action without a deliberation check.

Journey Context:
A 2026 study on moral reasoning in vision-language models found that image mode flattens utilitarian trade-offs, dissolves value hierarchies, and amplifies demographic bias compared to text or caption modes. Vision appears to activate fast, bias-prone processing while suppressing slow deliberation. Because most agents pass screenshots directly to the planner, this failure leaks into production. Captions alone do not eliminate it; an explicit dual-process architecture is the emerging guardrail. The tradeoff is latency, so reserve it for high-stakes actions.
