Context Engineering

Designing and managing everything placed in a model's context window to maximize task performance.

Definition

Context engineering extends prompt engineering to agents: choosing which instructions, retrieved documents, tool results, memory and history enter the context, and when to summarize, compact or offload information. Good context engineering keeps the window focused and within token budgets over long tasks.

Exam tip

More context is not always better; irrelevant tokens dilute attention and raise cost.
