Close the retrieval loop

Relevance check, groundedness check, stopping condition. The core of Corrective RAG.

Vanilla RAG is one shot: if it retrieved the wrong thing, it cannot recover. What actually raises quality is turning retrieval into a closed loop.

Three checks that close it

  • Relevance check. Are the retrieved chunks about the question? If not, search again before generating. This is the core of Corrective RAG.
  • Groundedness check. Is every claim in the answer present in the shown context? If not, narrow it or say "I do not know".
  • A stopping condition. At most N rounds. Otherwise the loop runs forever and you find out at the end of the month.
