Why building agents without this layer is like driving blind. And how to fix it.
You know exactly where to look when traditional software malfunctions. line number, stack trace, and error log. You’ll find the culprit in thirty seconds.
Photo by authorThis article discusses the importance of agent observability and evaluation in the development of AI agents, emphasizing that, unlike traditional software, agents present unique challenges in debugging due to their non-deterministic nature. It outlines the need for observability practices, which enable developers to understand the discrepancies between an agent’s actual actions and expected behaviors, and highlights the contrast between traditional software testing and the evaluation of agents, stressing that a new framework is necessary for addressing agent failures and ensuring reliability in production environments. The article also presents various evaluation techniques for agents, such as single-step and multi-turn evaluations, providing insights into how these methods can be effectively implemented.
