How to Write AI Prompts: Structure, Examples, Checks

How to Write AI Prompts So Answers Stay on Track

Sometimes it feels like the model “doesn’t get it,” but it’s usually doing exactly what you asked—just with too little context and no success criteria. Once you learn how to write AI prompts, you spend less time correcting vague output and more time getting results you can actually use.

What Should You Set Up Before Your First Prompt?

Why does a role change the quality of the answer?

A role is a frame for tone and depth: “You are an editor,” “You are a tutor,” “You are a product manager.” It reduces back-and-forth because the model starts in the right mindset. If you’re collecting practical workflows, it helps to keep how to use artificial intelligence at work nearby and match the role to the job.

How much context is enough without overloading the prompt?

Aim for 3–5 facts that would change the solution: who the audience is, what “done” looks like, what you’re starting from, and any hard limits on length or time. Extra background often dilutes the request instead of improving it.

Which constraints and criteria prevent fluffy output?

Ask like you’re writing a brief: “max 7 bullets,” “plain language,” “include examples,” “list risks,” “end with a short takeaway.” Add quality checks: “don’t invent facts,” “if something is unclear, ask clarifying questions first.”

Before you start (lowest risk → highest risk):

  • Low risk: ask for structure, ask for a plan, request examples, define the output format.
  • Medium risk: compare options, rewrite for a different audience, summarize and prioritize.
  • High risk: demand exact numbers without sources, make legal/medical calls without verification.
  • Stop sign: if the answer sounds confident but lacks dates, sources, or specific reasoning, switch to fact checking.

A Prompt Structure You Can Reuse

What does a solid prompt look like in six lines?

A reliable prompt is a simple build: role → goal → context → constraints → criteria → output format. Use this as a starting template and adjust it to your AI use cases.

FieldWhat to writeExample
RoleWho the model should beYou are an editor
GoalWhat you wantTighten this text without losing meaning
ContextWhere/for whomBlog post for beginners
ConstraintsLimits and styleUp to 150 words, no jargon
CriteriaHow “good” is measuredNo made-up facts, include examples
OutputFinal format5 bullets + a short takeaway

Which prompt examples work for work and school?

For work: “You are a support lead. Write a reply to a customer, calm tone, 2 options, under 120 words.” Expected result: a message you can send with minimal edits; rollback: “keep the structure, make it more neutral, remove salesy language.”

For school: “You are a tutor. Explain this topic so I can summarize in 90 seconds, then give me 3 self-check questions.” Expected result: a short explanation plus questions; rollback: “use an analogy and simplify the terms.”

When should you request clarifying questions first?

If your inputs are incomplete, say: “Before answering, ask me 3 clarifying questions.” It prevents guessing. This also pairs well with learning how to use AI Overviews: the guide on how to read AI Overviews critically helps you spot “nice-sounding” claims that need verification.

How Do You Improve Prompts Iteratively Without Losing the Point?

Why does “draft first, criteria second” work so well?

Start with a straightforward request and treat the first answer as a draft. Then add one or two constraints: “include counterarguments,” “show risks,” “rewrite for beginners.” Expected result: the second pass becomes tighter and more useful; rollback: “return to the first version and add only one constraint.”

How do you bake fact checking into the prompt?

“Fact-check it” is vague. Try: “mark which points require verification and suggest where to confirm them (official docs, dates, primary sources).” This is closely related to how to spot AI hallucinations: confident phrasing can hide invented details.

What’s the cleanest rollback when the model drifts?

Lock the boundaries: “keep the structure, change only tone,” “don’t add new facts,” “don’t change points 2 and 4.” Expected result: a targeted fix; rollback: “answer using only my inputs, no new assumptions.”

Quick Questions People Ask About Prompts

Why does the model sound smart but miss the target?

Usually the prompt lacks context and a definition of “good.” Add the audience, goal, and output format.

How many constraints are too many?

Three to five high-impact constraints beat a dozen minor ones. Group them by style, length, facts, and format.

Should you ask for “step-by-step reasoning”?

Often it’s better to request a clear structure and criteria. Steps are great when you want a checklist or a decision flow.

How do you know a prompt is “good”?

When you can reuse it and get consistently usable output with fewer edits. Keep one reference prompt and test new variations against the same criteria.

The habit that pays off most is simple: write prompts the way you’d brief a busy teammate—clear goal, just enough context, and a definition of success.
