Coherence Collapse: Diagnosing Why Code Agents Fail After Reaching the Right Code 事件

Coherence Collapse: Diagnosing Why Code Agents Fail After Reaching the Right Code arXiv:2603.24631v2 Announce Type: replace-cross Abstract: Code agents resolve 65-70% of SWE-bench Verified issues, but Pass@1 cannot tell us why the rest fail, and, as we show, capable-model failures are systematically misdiagnosed without trajectory data. We introduce TRAJEVAL, a training-free decomposition of agent trajectories into reference-patch-aligned search, read, and edit stages, and apply it across 16,75
