Failure as a Process: An Anatomy of CLI Coding Agent Trajectories (arxiv.org)

A new study titled "Failure as a Process: An Anatomy of CLI Coding Agent Trajectories" examines the failure mechanisms of large language model coding agents in terminal environments. By focusing on 3,843 execution trajectories from various models, researchers have developed a process-oriented framework for understanding failures as dynamic phenomena rather than static endpoints. The analysis, which filtered down to 1,794 valid trajectories, highlighted key factors leading to failures, including the prevalence of epistemic errors that often arise in the early execution steps. This research is significant for the AI/ML community as it challenges the conventional approach to evaluating coding agents, advocating for a shift towards early intervention and validation while coding is in progress. It underscores the importance of recognizing and addressing failures throughout the execution process rather than merely assessing outcomes after the fact. By providing 14 findings on failures' occurrences, root causes, and recovery options, the study offers valuable insights that could enhance the reliability of coding agents in software engineering, pointing towards the necessity for frameworks that support timely corrective actions.
