Report #29396

[frontier] Agent latency exceeds 30s per step because it alternates between text planning and vision verification in a tight loop

Batch all visual perception into a single round-trip: perform all text-based planning first, then execute a single 'visual verification' round-trip with multiple screenshots grouped; use text-only models for intermediate reasoning to avoid vision token overhead.

Journey Context:
Vision API calls have significantly higher latency \(often 2-5x\) and cost than text-only calls due to image encoding and processing. A common anti-pattern is: 'think \(text\) -> look \(vision\) -> think \(text\) -> look \(vision\)'. This doubles the latency. The efficient pattern is 'think all the way \(text-only\) -> do all actions -> look once \(vision\) -> correct'. This reduces API costs and latency significantly.
