Build agentic retrieval on a Managed Amazon Bedrock Knowledge Base with CDK
TL;DR
Build enterprise agentic retrieval on a Managed Amazon Bedrock Knowledge Base with the AWS CDK: an agent that routes across two knowledge bases, retrieves through the AgentCore Gateway, and returns grounded, cited answers, with seven layers of observability and both on-demand and continuous evaluation, all deployed as a single CDK application.
Nauti's Take
Start by testing whether the two knowledge bases cleanly cover different question domains and whether every answer traces back to a source file. The CDK setup improves repeatability, but a small golden test is still needed to measure latency, cost, and misrouting across both retrieval paths.
