[frontier] Naive RAG retrieves irrelevant chunks, causing agents to hallucinate or fail on complex multi-hop queries

Replace single-pass retrieval with Agentic RAG—implement iterative retrieval-reflection loops where the agent critiques retrieved documents before generation, triggering re-retrieval with reformulated queries until confidence thresholds are met

Journey Context:
Standard RAG assumes the first retrieval is sufficient, failing on ambiguous or multi-hop queries. Production failures show agents need to evaluate retrieval quality. The emerging pattern \(pioneered in Microsoft's GraphRAG and research on Self-RAG\) uses a reflection step: the agent generates a critique of retrieved chunks \(are these relevant? what's missing?\), then conditionally re-retrieves with refined queries. This transforms RAG from a static pipeline into an agentic loop, drastically reducing hallucination on complex queries by allowing the agent to 'search harder' when uncertain.
