[frontier] Naive RAG retrieves irrelevant chunks and the agent generates confident but wrong answers from poor context

Replace retrieve-then-generate with an agentic RAG loop: \(1\) agent formulates a search query, \(2\) retrieves results, \(3\) critiques whether results are sufficient and relevant to the question, \(4\) if not, reformulates query and re-retrieves, \(5\) only generates when critique passes. Implement the critique as an explicit step with its own prompt that evaluates retrieved context against the original question.

Journey Context:
Naive RAG — embed query, retrieve top-k, stuff into prompt, generate — fails on complex questions because the initial query is ambiguous, top-k returns irrelevant chunks, and the LLM confidently hallucinates from poor context. The fix isn't better embeddings or more chunks; it's making retrieval agentic. The agent decides when to search, evaluates what it finds, and iterates. The self-critique step is the critical innovation — without it, the agent just generates from whatever it retrieved, which is no better than naive RAG. The tradeoff: more LLM calls and higher latency \(2-5x per question\). But production teams report 40-60% reduction in hallucinated answers. This pattern — agentic RAG with self-critique — is replacing naive RAG in every production system that cares about accuracy.
