Multi-turn agents exhibit failure patterns not detectable through single-turn evaluations. A single error can propagate through subsequent turns, making traditional metrics inadequate. The Agent Evaluation Metric (AEM) addresses this limitation by offering a decomposable, turn-level measurement of agent quality. It focuses initially on correctness, allowing engineers to isolate the exact turn contributing to a failure. This separation is crucial for debugging and improving agent behavior.
AEM’s design separates the impact of a faulty turn from the influence of subsequent turns. This allows for a more accurate assessment of the agent’s overall quality. The metric provides a detailed breakdown of agent performance, facilitating targeted interventions and reducing the risk of introducing new errors during modifications.
This approach is particularly relevant for production environments where agents engage in complex, multi-turn conversations. Identifying the root cause of a failure quickly minimizes downtime and ensures consistent performance. The metric’s turn-level analysis provides actionable insights for optimizing agent design and training data.
