Report #70551

[frontier] RAG outputs violate downstream schema requirements requiring costly re-prompting

Constrain RAG output generation using structured generation libraries \(Outlines, Guidance\) that enforce JSON schema or regex constraints at the token sampling level; combine retrieval with grammar-based generation

Journey Context:
Naive RAG retrieves context then hopes the LLM formats correctly; structured generation bakes the schema into the logits. This eliminates parsing errors and reduces token waste on format correction. It replaces 'prompt engineering for JSON' with guaranteed valid outputs. Tradeoff: slightly reduced creativity/output diversity, but essential for agent-to-agent communication protocols.
