Report #76689

[frontier] Agent clicks wrong UI element due to coordinate drift and ambiguous visual references

Overlay numbered Set-of-Mark \(SOM\) markers on screenshots before VLM processing; force agent to reference markers by ID rather than raw coordinates or natural language descriptions

Journey Context:
Raw pixel coordinates fail across resolutions and dynamic layouts; DOM selectors break on Shadow DOM and canvas apps. SOM creates a stable visual API layer that survives styling changes. The pattern requires generating overlays \(SVG/PNG markers\) and injecting them into the screenshot pipeline before VLM encoding, effectively creating a 'visual API' that grounds actions to specific regions.
