Taxbit Assist: A grounded, role-aware AI agent on Amazon Bedrock AgentCore
Taxbit built a permission-aware, citation-grounded AI assistant inside its digital-asset tax compliance dashboard using Amazon Bedrock AgentCore. The post details its architecture: Strands Agents SDK on AgentCore runtime, Bedrock Guardrails screening, a curated Bedrock Knowledge Bases index backed by Amazon S3 Vectors, Cohere embeddings and reranking, and per-session isolation. It also shares retrieval lessons such as excluding marketing pages, prepending document scope to chunks, and enforcing citation eligibility in code, plus continuous production evaluation and human-corrected answers.
Why it matters: It offers a concrete, production-tested case study of retrieval, grounding, identity binding and evaluation practices for shipping a regulated-domain AI agent.
