Report #35730

[frontier] RAG retrieval returns irrelevant context for complex queries

Build agentic RAG with tool-use feedback loops where the agent executes intermediate verification tools to confirm sources before final generation

Journey Context:
Naive RAG fails on multi-hop questions requiring synthesis across documents. The 2025 production pattern uses LangGraph to create loops where the LLM generates search queries, retrieves chunks, then uses additional tools \(like web search or calculator\) to verify the retrieved facts before answering. This reduces hallucinations by 60%\+ compared to single-pass RAG.
