What Is Context Engineering?

Context engineering is presented as the practice of managing the full set of information available to an AI model during inference, including system instructions, conversation history, retrieved documents, tool outputs, long-term memory, and user profiles, rather than focusing only on prompt wording. The discussion argues that production agents often fail because of stale, missing, irrelevant, ambiguous, or contradictory context, and that larger context windows do not resolve these issues due to computational costs, “lost-in-the-middle” behavior, and declining signal-to-noise ratios. It recommends techniques such as progressive disclosure, conversation compression, query routing, context isolation, retrieval augmentation, hybrid search, reranking, and contextual retrieval, which adds explanatory metadata to document chunks before embedding them. The text also emphasizes persistent memory and personalized user profiles for maintaining useful state across sessions, and promotes Supermemory as an infrastructure platform combining connectors, multimodal extraction, hybrid retrieval, memory graphs, and profile data, citing performance and accuracy benchmarks in comparison with other memory tools.
