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.
What your prompt actually needs
Think of writing a prompt like leaving a note for a really smart helper. The note should tell them: who you need them to be, what you need done, what it should look like when they're finished, and anything they should know about your situation.
There are four things that make the biggest difference:
Who you need the AI to be. You can ask it to take on a role, or you can just describe your situation. "I'm a first-time homebuyer and I don't understand what escrow means" gives the AI everything it needs to answer in a way that's actually helpful to you — not just a dictionary definition.
What you actually want. Be specific about the task. "Help me with my aunt's birthday" gives the AI nothing to work with. "Write a warm, funny birthday message for my aunt who just turned 70 and loves gardening and bad puns" is something it can actually do.
What it should look like. Do you want a short paragraph? A numbered list? A simple table? The AI will make something up if you don't say — and it might not be what you had in mind. Just ask for what you need.
Who it's for and what to avoid. "Keep it simple — my dad isn't great with technology" or "don't make it sound too formal, she's my friend" or "keep it under three sentences" all change the answer in useful ways.
See the difference
Here's the same request, two ways:
Task: Write an email
Help me write an email.
Help me write an email to my son's teacher. I want to ask why his grade dropped from a B to a D this semester and set up a time to talk. I want to sound concerned but not accusatory. Keep it short — just a few sentences.
The specific version tells the AI who the email is for, what the situation is, what tone to use, and how long to make it. The vague version gives it 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.
The four-part prompt framework
You don't need all four parts every time — a simple question doesn't require a role and audience brief. But for anything substantial, running through this checklist catches most of what makes prompts fail:
- Who should the AI be, or what does it need to know about you?
- What exactly do you want it to do?
- What should the answer look like? (list, paragraph, table, short, detailed...)
- Who is it for, and is there anything it should avoid?
A message built on all four of these is hard to misunderstand. That's the goal.
Build your own prompt
Here's the framework in action. Pick your situation and what you need — the prompt builds itself.
Prompt
I am [situation] and I need help [task]. Please give me the answer as [format]. [extra]
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.
