AgentBug-Smith: Automatically Reproducing Real-World Harness Bugs in Agentic Systems

Agent harness bugs exhibit unique characteristics and remain challenging for state-of-the-art software agents to repair. Progress in this area is further hindered by existing benchmarks, which contain only a small and fixed number of executable harness bugs while requiring hundreds of human hours to construct. This wor...
