Amazon Bedrock AgentCore now includes Policy (preview), Evaluations (preview) and more

Posted on: Dec 2, 2025

Today, Amazon Bedrock AgentCore introduces new offerings, including Policy (preview) and Evaluations (preview), to give teams the controls and quality assurance they need to confidently scale agent deployment across their organization, transforming agents from prototypes to solutions in production.

Policy in AgentCore integrates with AgentCore Gateway to intercept every tool call in real time, ensuring agents stay within defined boundaries without slowing down. Teams can create policies using natural language that automatically convert to Cedar—the AWS open-source policy language—helping development, compliance, and security teams set up, understand, and audit rules without writing custom code. AgentCore Evaluations helps developers test and continuously monitor agent performance based on real-world behavior to improve quality and catch issues before they cause widespread customer impact. Developers can use 13 built-in evaluators for common quality dimensions, such as helpfulness, tools selection, and accuracy, or create custom model-based scoring systems, drastically reducing the effort required to develop evaluation infrastructure. All quality metrics are accessible through a unified dashboard powered by Amazon CloudWatch. We’ve also added new features to AgentCore Memory, AgentCore Runtime, and AgentCore Identity to support more advanced agent capabilities. AgentCore Memory now includes episodic memory, enabling agents to learn and adapt from experiences, building knowledge over time to create more humanlike interactions. AgentCore Runtime supports bidirectional streaming for natural conversations where agents simultaneously listen and respond while handling interruptions and context changes mid-conversation, unlocking powerful voice agent use cases. AgentCore Identity now supports custom claims for enhanced authentication rules across multi-tenant environments while maintaining seamless integration with your chosen identity providers.

AgentCore Evaluations is available in preview in four AWS Regions: US East (N. Virginia), US West (Oregon), Asia Pacific (Sydney), Europe (Frankfurt). Policy in AgentCore is available in preview in all AWS Regions where AgentCore is available.
