"Context engineering is the delicate art and science of filling the context window with just the right information for the next step." — Andrej Karpathy. A practical, first-principles handbook inspired by Karpathy and 3Blue1Brown for moving beyond prompt engineering to the wider discipline of context design, orchestration, and optimization.
