10.2. What Makes a 'Good' Prompt?

✅ Relevance Does the response align with the prompt’s intent?

Relevance is about ensuring that the response generated from the prompt meets the intent behind the prompt. This means that the output should directly answer the question or fulfill the task posed by the prompt. If a student asks, 'What is photosynthesis?' they expect a clear explanation of that process rather than unrelated information about plant growth.

Imagine you're ordering a pizza and you say, 'I want a vegetarian pizza.' If the pizza you receive has meat toppings, it shows that the order wasn't understood. Similarly, a good prompt should deliver responses that align closely with what was asked.

✅ Clarity Is the output clear and understandable to the end user?

Clarity means that the response should be easy to read and comprehend for the intended audience. If the language is too complex or technical, the user might struggle to understand it, which defeats the purpose of effective communication.

Think about reading a recipe: if it's written in jargon with complicated terms, you might feel confused. A clear recipe uses straightforward language and step-by-step instructions to make the cooking process easy to follow.

✅ Factual Accuracy Are facts, numbers, or logical steps correct?

Factual accuracy ensures that the response contains correct information. This involves verifying that any statistics, facts, or logical progressions presented in the output are true and reliable. Misinformation can lead to confusion or misguided actions.

Consider a history lesson where facts about a significant event are misrepresented; if students learn incorrect dates or events, it alters their understanding of history, just like inaccurate outputs from prompts can misinform users.

✅ Structure/Format Does it follow the expected format (e.g., bullets, JSON)?

The response should be organized in a way that matches the expected structure. This might involve using lists, tables, or specific formatting styles. Following a proper structure helps users to quickly find and process information.

Think of a syllabus: if it lists topics in a clear outline format, students can easily grasp what they will learn. But if it just contains a block of text with no formatting, it can be overwhelming and hard to navigate.

✅ Tone Appropriateness Is the tone suitable for the task (e.g., formal, friendly)?

The tone of the response should match the context of the prompt. For example, a prompt asking for a professional report should produce formal language, while a prompt designed for a child could be more casual and friendly. The right tone fosters better engagement and aligns expectations.

When talking to a friend, you might use slang and a relaxed tone, but when addressing a teacher, you would choose more formal language. Just like in conversations, the right tone makes interactions more effective.

✅ Consistency Does it produce stable results across similar inputs?

Consistency refers to the ability of the prompt to yield similar outputs when given similar inputs. This is crucial when users need to rely on the prompt for accurate forecasting or decision-making. Inconsistent responses can create confusion and doubting of the system's reliability.

Imagine a vending machine: if you press the button for a soda and sometimes it gives you a soda and other times a snack, you'd likely lose trust in that vending machine. Similarly, prompts need to deliver reliable results for users to trust them.
