Runnable Commit Untangling for Coding Agents

The paper "Runnable Commit Untangling for Coding Agents" introduces RucTangle, an agentic method that untangles large, tangled patches from coding agents while ensuring each commit keeps the code runnable. It also presents TangleEval, an evaluation framework that measures how untangled commit histories aid agents in repairing bugs. Experiments on 131 agent-generated patches show RucTangle produces fully runnable histories, outperforming baselines that leave 20.6%-37.4% of commits unrunnable, and improves bug‑repair success by 5.2% absolute in pass@1.
