Report #57560

[frontier] RAG retrieves irrelevant chunks and fails on multi-hop reasoning requiring entity relationships

Use Microsoft GraphRAG to build knowledge graphs, then deploy a validation agent to traverse and prune the retrieved subgraph for coherence before passing to the generation agent

Journey Context:
Naive RAG fails on 'Why did X happen?' questions needing connections across documents. GraphRAG extracts entities/relationships into a graph. The frontier pattern adds an agent \(not just a prompt\) that traverses this graph, checks for contradictions, and verifies that the retrieved subgraph actually answers the query. This agent may perform 'sub-queries' to fill gaps. Only validated subgraphs go to the main LLM, drastically reducing hallucinations on complex queries.
