[frontier] My vision agent keeps clicking the wrong UI element

Overlay numbered marks on interactive elements and have the model return element IDs; combine with an accessibility tree or element list for candidate generation.

Journey Context:
Raw coordinate prediction is brittle because small errors compound. Microsoft's Set-of-Mark prompting makes regions 'speakable' by overlaying numbers, enabling GPT-4V and open models to ground actions reliably. It is now the default pattern in SeeAct, OmniParser, and GUI grounding benchmarks. Common mistakes: marking non-interactive clutter, using too-dense labels, or relying on marks without a structured candidate list. SoM works best when paired with element detection that filters candidates first.
