Report #43576
[frontier] Agents with vision access default to heuristic pattern-matching instead of symbolic reasoning causing errors on novel UI layouts
Enforce explicit textual Chain-of-Thought \(CoT\) before visual action; use text-only reasoning phase then vision-enabled action phase
Journey Context:
VLMs exhibit 'visual shortcutting' - recognizing UI patterns from pre-training \(e.g., 'hamburger menu' = navigation\) and skipping analytical steps. This causes brittleness when UIs deviate \(e.g., hamburger icon opens search\). Forcing text-only CoT preserves symbolic reasoning pathways \(System 2 thinking\) before vision provides grounding. Alternatives like few-shot CoT examples help but don't prevent drift; vision suppression during reasoning is the only reliable mitigation. Essential for enterprise UIs with non-standard design systems.
