Context engineering is emerging as a distinct discipline from prompt engineering, focusing on the deliberate curation of all information a language model receives during an inference call. This includes system prompts, user input, retrieved documents, conversation history, and tool definitions. The shift is driven by the rise of AI agents that operate in multi-step, tool-using loops, where managing the accumulated context becomes the primary challenge rather than just crafting the initial instruction. Factors like context rot in larger windows and the economic realities of token usage in production agents have further solidified context engineering as a critical skill for building effective AI systems.
