Report #1987

[research] RAG agent outputs look plausible but are based on irrelevant retrieved context, making final-output evals misleading

Separate evals into retrieval metrics \(Context Precision/Recall\) and generation metrics. Run context-only evals first; if retrieval fails, block the agent run and flag the retrieval pipeline, not the LLM.

Journey Context:
Evaluating the final output of a RAG agent is a composite test. If the agent retrieves the wrong document but answers correctly based on it, the eval might pass, masking a critical retrieval failure. By evaluating the retrieved context independently, you isolate the failure mode and prevent silent degradation of the vector store or embedding model.
