Definition
In the context of RAG and AI Agents, a Recommendation System refers to the retrieval and ranking architecture that identifies the most relevant context chunks or specialized tools from a large knowledge base or toolset to populate an LLM's prompt. It prioritizes information density and relevance to ensure the agent reasoning engine operates on the most pertinent subset of data available.
In RAG, this is context-selection logic for the model, not product-selection logic for a consumer.
"A Surgical Tray: The system selects only the specific, sharpened instruments (data shards or tools) required for the current procedure (query), rather than presenting the entire hospital inventory."
