Explicit tables beat narrative text for LLM RAG context

A developer testing LLM context utilization found that even when RAG retrieves the right documents, models often fail to use the information unless it is formatted as explicit tables, short text, or raw code rather than implicit narrative logic.

// ANALYSIS

This highlights a major blind spot in basic RAG implementations: successful vector retrieval doesn't guarantee successful generation.

–LLMs struggle to follow implicit rules ("the system usually does X") but excel when given explicit mapping logic like CUST-{id}.
–Tables and raw code snippets have a significantly higher signal-to-noise ratio for data extraction than descriptive paragraphs.
–Isolating a single document in a "clean context" is an essential debugging technique to determine if a failure is a retrieval problem or a reasoning problem.
