What Is Prompt Engineering? Definition and Example
Definition

Prompt engineering is the practice of writing and refining prompts so that an AI gives reliable, useful results.

What it means

It includes giving context, stating the output format, adding examples, setting limits and iterating after a weak answer. For most people it is a communication skill, not a coding skill. In technical settings it also covers testing prompts at scale.

Example

You compare three versions of a prompt on the same task, keep the one that produces the best result, and save it in a library.

Why it matters

Good prompting saves time and reduces mistakes, and it is the foundation for building automations and agents.
