# Prompt Engineering
The practice of crafting a single message to get a better response from a language model.

## Definition
Prompt engineering focuses on the quality of the input message: word choice, structure, examples, instructions within the prompt itself. It works when the interaction is a single exchange. In an agentic context, prompt engineering is a subset of context engineering. The individual message matters less than the system that assembles everything the model sees across an entire session.
