arXiv: Beyond the Parameters — Technical Survey of Contextual Enrichment from In-Context Prompting to Causal RAG

arXiv·low signal

A comprehensive technical survey (Bansal, Agarwal) mapping the full spectrum of contextual enrichment techniques for LLMs, from in-context prompting through causal retrieval-augmented generation. The survey covers the evolution from static knowledge to dynamic context injection — directly relevant to how production agents maintain up-to-date knowledge. For agent builders, the causal RAG section is particularly valuable: it addresses how to build retrieval that understands causal relationships rather than just semantic similarity, which is critical for agent decision-making in complex workflows.
