Compile the model’s working state
Prompt engineering shapes an instruction. Context engineering—sometimes casually called contextual engineering—decides the complete token state the model receives at each inference step: instructions, evidence, tool schemas, skills, memory, conversation history, and recent tool results.
Use the context compiler to add, remove, and prioritize real categories of state. The model’s weights never change. What changes is the finite working set from which the next action is sampled.
