What Makes a Good Prompt
Here is the thing most people don't realize: when AI gives you a vague or unhelpful answer, it's usually not because the AI is bad. It's because the question was vague.
Think about asking for directions. "How do I get there?" gets you nothing. "How do I get from the Target on Main Street to the hospital on 5th — I'm driving and I want to avoid the highway" gets you exactly what you need. The AI works the same way.
This works the same whether you're using Claude, ChatGPT, or Gemini.
The Five-Part Prompt
The first four parts do the heavy lifting — the fifth is a bonus when you need it:
- Context — What does the AI need to know about your situation? Who are you, and what's going on?
- Task — What exactly do you want it to do?
- Tone / Audience — Who is this for, and at what level? (explain like I'm 5, write for a non-technical reader, keep it casual...)
- Format — What should the answer look like? (list, paragraph, table, short, detailed...)
- Constraints (optional) — Is there anything it should avoid or stay within?
Here's what a prompt looks like when all five are working together:
Context: My doctor just told me I have stage 1 high blood pressure. I'm 58 and I've never had to manage a health condition before.
Task: Explain what this means, what lifestyle changes actually help the most, and what questions I should ask at my next appointment.
Tone / Audience: Write as if explaining to someone who is nervous and has zero medical background.
Format: Give me a short explanation first, then a bulleted list for the lifestyle changes and questions.
Constraints (optional): Don't recommend expensive treatments or supplements — I want practical, everyday changes only.
A message built on these is hard to misunderstand. That's the goal.
Bonus technique: give the AI a role
Context tells the AI about you. But you can also tell the AI who to be. Phrases like "You are a financial advisor explaining this to a first-time investor" or "Act as a patient, plain-English doctor" change not just the tone but the whole perspective of the answer. This is separate from providing your own context — and most prompts don't need it — but it's a powerful option when you want a specific expert lens on your question.
See the difference
Here's the same request, two ways:
Task: Write an email
Help me write an email.
I'm a parent — my son's grade dropped from a B to a D this semester and I want to understand what's going on. Write an email to his teacher asking what happened and requesting a time to meet. The tone should be concerned and collaborative, not accusatory — I want her to feel like we're on the same team. Keep it to 3–4 sentences and avoid stiff or overly formal language.
The specific version uses all five parts: context (who I am and what's happening), task (write an email asking two things), tone (concerned, collaborative, not accusatory), format (3–4 sentences), and a constraint (no stiff language). The vague version gives the AI nothing to go on.
Task: Understand a health situation
Tell me about high blood pressure.
My doctor just told me I have stage 1 high blood pressure. I am 58 years old and I have never had to manage a health condition before. Can you explain what this means in plain language, what lifestyle changes actually help, and what questions I should ask at my next appointment?
Telling the AI your situation — your age, what you already know, and what you specifically need — completely changes the answer you get.
Build your own prompt
Here's the five-part framework in action. Fill in each part and the prompt builds itself.
Prompt
[context] [task] [tone] [format] [constraints]
You don't need to write a novel
Being specific doesn't mean being long. A prompt that buries the actual question in three paragraphs of backstory is still a problem.
If you find yourself writing a lot of background before getting to what you actually need, flip the order: say what you want first, then add the context. The AI reads everything before it answers — but leading with the request helps it stay focused on what matters.
Ask the Expert How to Ask the Expert
Here's a trick that sounds almost too obvious once you hear it: if you're not sure how to ask for something, just ask the AI how you should ask.
Prompt
I want to [describe what you're trying to accomplish]. What's the best prompt I could give you to get a really useful answer?
Think of it like calling a restaurant to ask what you should order. The person who answers the phone knows the menu better than you do.
The next lesson is about what to do when the first answer isn't quite right — because even a great prompt sometimes needs a follow-up or two.
