Loop Engineering for Cross-References: When RAG Answers ‘see Section 7.2’ Instead of the Actual Answer

Retrieval-Augmented Generation (RAG) systems can fail when they return a pointer to another section of a document, such as "see Section 7.2," instead of the actual information. A technique called "Loop Engineering" solves this by implementing a multi-pass pipeline. During the first pass, the language model identifies and flags any unresolved references found in the retrieved context. An orchestrator then uses this signal to resolve the reference, fetch the linked content, and re-run the generation step with the newly added context. This iterative process ensures the final answer is complete and directly addresses the user's query without requiring them to manually track down cross-references.
