Amazon Bedrock AgentCore adds detection for silent agent failures that pass health checks

AWS Machine Learning Blog·medium signal

AWS shipped AgentCore optimization insights that surface behavioral failures in production agents — the ones that return successfully and pass every health check while delivering wrong outcomes. This is the observability gap that separates demo agents from production ones: liveness monitoring tells you nothing about correctness. Directly relevant to anyone running unattended agent pipelines where nobody reads the output until it's already published.
