For example, in ChatGPT, whatever you type into the input box is the prompt. Prompt engineering is the skill of writing prompts in a way that reliably produces the result you want. It may feel like “just typing in a chat box,” but the quality of the output can change dramatically depending on how you phrase and structure the input—so people call it “engineering” because there are principles, trade-offs, and know-how.</p>
