aws.amazon.com·May 18, 2026

The content discusses the implementation of custom code-based evaluators for Amazon Bedrock AgentCore, focusing on their application in financial services to ensure quality and compliance in agent performance. It outlines how these evaluators can be used in both on-demand and online modes to assess various quality dimensions such as schema validation, numerical accuracy, workflow compliance, and PII detection, ultimately enhancing the reliability of agentic applications.

For enterprise AI professionals, leveraging AWS's custom code-based evaluators in Amazon Bedrock AgentCore can significantly enhance the reliability of agentic AI systems by enabling deterministic evaluations that are critical in specialized domains like financial services. These evaluators allow you to enforce strict compliance with data accuracy, workflow integrity, and PII protections without relying on the inherent variability of LLM-based evaluations. Implementing these in on-demand and online modes ensures continuous quality monitoring and regression testing, thereby supporting robust CI/CD workflows and improving deployment confidence in enterprise AI applications.
