Amazon Bedrock AgentCore adds versioned dataset management for stable agent evaluation baselines

“Without it, you're measuring the appearance of correctness, not correctness itself.”

AWS Bedrock AgentCore now supports versioned test datasets for agent evaluation, allowing teams to lock immutable test fixtures with ground truth so scores are comparable across runs. The system addresses a core LLMOps problem: non-deterministic agents make single evaluation scores meaningless without stable inputs and explicit assertions. This bridges the inner developer loop and outer CI/CD gate into a unified evaluation discipline.
