Coding agents often fail not at the initial task understanding, but in the execution phase, making subtle errors that cascade into incorrect final outputs. Current training and evaluation methods, like SWE-bench, focus on the final outcome (pass/fail) and overlook the trajectory, missing crucial information about where and why an agent deviates from a correct path. To improve agent reliability, future training should incorporate detailed step-by-step annotations of failure points and explicitly teach agents recovery mechanisms by providing data that includes detection, diagnosis, and correction of errors.
