This piece covers how a question-parsing brick transforms a raw user string into four typed pieces (ParsedQuestion, retrieval brief, generation brief, and ClarificationRequest), each consumed by a different downstream component. Using LangChain's four canonical strategies (write, select, compress, isolate), it explains why each piece is kept separate: to prevent accidental coupling between retrieval and generation, maintain fine-grained cache boundaries, and allow ambiguous questions to be held at the clarification stage rather than forwarded as low-confidence guesses. Five concrete examples with real JSON outputs illustrate how fields like section_hint, layout_hint, and pages_hint activate specific retrieval behaviors, and why merging all fields into a single payload would undermine the architecture. ## Full article daily.dev links to this article rather than hosting it.
