Merged summary
TL;DR - HarnessLens is a budget-aware framework that evolves agent harnesses while selectively testing candidate changes on behavior-relevant tasks. It improves held-out performance by 7.6–13.6% across multiple harnesses and benchmarks while using substantially less evaluation budget than competing methods.
- Jointly explores task space and user-configurable harness components.
- Proposes modifications based on agent execution trajectories.
- Uses an attributable-evidence gate to target verification and detect behavior-specific regressions.
- Evaluated on three agent harnesses and four benchmarks under constrained interaction budgets.
