Report #58497

[frontier] Naive RAG \(single retrieval then generate\) fails on complex queries requiring multi-hop reasoning or when initial retrieval is off-target

Implement iterative retrieval where the agent uses tool calls to reformulate queries based on initial results, verify retrieved content against the question, and retrieve additional context until confidence thresholds are met

Journey Context:
Simple vector similarity RAG hit limits on 'compare X and Y' or 'why did Z happen' questions requiring multiple retrieval steps. The evolution: treat retrieval as an agent workflow with feedback loops. The agent uses retrieval tools multiple times, refining the search space like a researcher would. This replaces the static RAG pipeline with a dynamic, agentic retrieval process where the LLM decides what information is missing and how to find it.
