StarHarness is a new framework designed to improve the performance of enterprise AI agents by evolving their surrounding 'harness' rather than the model weights themselves. This approach focuses on optimizing prompts, tool interfaces, and execution logic. Across several enterprise benchmarks, StarHarness demonstrated significant performance gains, improving scores by 20-35 percentage points and reducing inference costs. Notably, an evolved harness allowed a smaller open-weight model to outperform a larger frontier model, suggesting that harness optimization is crucial for effective tool use in complex enterprise environments.
