  "account": "When a CI pipeline is overwhelmed with failed tests, teams often clear the backlog by running reruns to clear the red builds. However, this leaves the root cause of the failures unidentified. A new AI model called Jev from TypeSafe AI claims to be able to categorize failures quickly, but tests have shown that its accuracy is low. Therefore, it is clear that evidence must be collected before applying any classifier.\n\nThe three main categories of CI failures are product defects, environment noise, and agent errors. Product defects can be traced back to recent changes in the application, environment noise manifests as timeouts or 5xx responses from dependencies, and agent errors occur in a healthy environment with unchanged commits but different agent steps.\n\nA fourth category, test defects caused by shared state across parallel workers, can also appear similar to environment noise. To differentiate this category, a fourth label should be added to the classifier, and rerunning each failure with a single worker can help identify it.\n\nAgent errors are the most challenging to identify since the evidence lies in the agent's decisions rather than logs. A trace of every action taken by the agent, with full context, should be captured and reviewed by separate evaluators for logic errors. This detailed trace can help anticipate and prevent agent errors before they occur.",
