Prompt Engineering
Prompt engineering is the practice of crafting precise instructions to steer a language model's output toward the intended result.
Word choice, instruction order, provided examples, and the requested format all directly affect the quality of a generated answer. A good prompt reduces ambiguity and limits hallucinations.
It's a cross cutting skill. It's used to configure an AI agent, to query an assistant for research, or to test how a website's content gets summarized by a model.
