Self-improving harnesses are one of the most discussed ideas in AI right now. (bookmark it) This work proposes a new harness, RuHarness, that beats the strongest harness-evolution baseline by 4.5 points on held-out tasks with Qwen3.5-35B-A3B, and by 5.3 points with GLM-4.7-Flash. The work targets a gap in current methods. They evolve the harness but keep the criteria that guide each edit fixed, so the criteria stop matching the agent's weaknesses after a few rounds. RuHarness evolves the rubric along with the harness. Each round, it finds behavioral criteria in the trajectories, re-scores
