A new benchmark called RegretBench has been developed to evaluate the backup awareness of coding agents, which are increasingly capable of autonomous task completion. The benchmark, comprising 205 tasks based on user-reported regrets from platforms like GitHub and Stack Overflow, revealed that current frontier models complete tasks effectively but demonstrate poor backup awareness, preserving state only 15.2% of the time. To address this, a plug-in layer named BackUpper was proposed, which automatically checks tool calls and preserves affected states before modification, achieving 92.2% state restoration similarity on RegretBench at a low cost and with fewer tokens than agent self-backup.
