[frontier] Visual Saliency Trap: Agents click high-contrast UI distractions instead of semantic targets

Pre-filter screenshots with accessibility tree masking to hide visually salient but semantically irrelevant UI elements \(ads, animations\) before vision model processing

Journey Context:
Screenshot agents gravitate to high-contrast buttons and moving elements instead of task-relevant targets. DOM-based approaches miss visual affordances; pure vision misses semantic intent. The fix isn't better prompting—it's pre-processing screenshots to mask non-interactive or irrelevant regions using accessibility tree data, creating attention masks that guide the vision model to semantically important regions only.
