arXiv 2607.25825 targets the layer builders actually control, arguing today's harnesses use hand-crafted or globally fixed policies that mismatch task demands and burn compute. It estimates workflow advantage from confidence-weighted execution evidence and only applies adjustments backed by sufficient expected advantage. Across long-horizon information-seeking, software engineering, and terminal tasks, it preserves task success while substantially cutting tokens and wall time.
