Four forensics when a production AI agent fails
A founder reached out for help when their AI customer support agent began malfunctioning shortly after launch. The engineering team initially treated the issue as a single problem, but it was actually four distinct failure modes. The article outlines a forensic approach to diagnosing these failures, emphasizing the importance of analyzing traces and understanding external dependencies.
- ▪The AI agent was reported to be giving incorrect answers and experiencing long response times.
- ▪The engineering team discovered that the issues stemmed from multiple failure patterns rather than a single problem.
- ▪Common causes of failure included external dependency degradation and validation gates not functioning properly.
