AWS how-to: build a cited-answers claims assistant with Amazon Bedrock Knowledge Bases

AWS published a technical how‑to showing how to index claim documents from Amazon S3 into Amazon Bedrock Knowledge Bases and use the AgenticRetrieveStream API to answer natural‑language questions with streamed trace events, citations, and grounding checks; the walkthrough uses synthetic claim records and demonstrates scoping via metadata filters and a contextual grounding guardrail. The guide explains ingestion (parsing, chunking, embeddings, vector storage), agentic retrieval that iterates sub-queries, and streaming of answers, traces, and citations to support auditable, source-backed responses.
