The agent evaluation playbook: Built-in, DeepEval, and AutoEval on Amazon Bedrock AgentCore Evaluations

By · Published by Everything Blog

In short

Relying merely on latency tracking or basic completion rates often masks critical operational failures, such as agents skipping mandatory steps or exposing personally identifiable information. Amazon Bedrock AgentCore Evaluations provides a structured catalog of tools to assess systems against clear business outcomes. The service features built-in evaluators alongside hosted third-party options like DeepEval and AutoEval on managed infrastructure. Teams can also implement fully customized evaluators using their own specialized rubrics and models.

The agent evaluation playbook: Built-in, DeepEval, and AutoEval on Amazon Bedrock AgentCore Evaluations

When you deploy an agent to production, one of the hardest questions is whether it’s actually working? The bar isn’t whether it runs. It’s whether it does what the business needs, at scale. Many teams will tell you they can’t really see this. They spot-check outputs, watch latency, and collect user feedback when they can get it. None of that tells you whether the agent finished the user’s task, stayed on topic across a long session, leaked personally identifiable information (PII), or quietly skipped half the steps it was supposed to follow.

Agent evaluation solves this problem. What makes this challenging is that a good score on one metric can hide a failure on another. A support agent can resolve every ticket and still expose personal information in its replies. In this case, the agent is failing although it has a high completion rate. To get evaluation right, measure the behaviors that matter for each agent, at the right level of detail.
