Prompt Writing 101: Get Dramatically Better AI Answers
The five-part prompt formula that turns vague AI replies into genuinely useful work, with before-and-after examples you can copy today.
The gap between a mediocre AI answer and an excellent one is usually not the model. It's the prompt. The good news: prompting is not a dark art. It's mostly the skill of briefing a very fast, very literal assistant.
The five-part formula
Strong prompts tend to contain five ingredients. You won't need all five every time, but knowing them turns "why is this answer so generic?" into a checklist.
- Role: who the AI should act as. "You are an experienced UK employment lawyer."
- Task: the specific job. "Review this contract clause and flag risks for the employee."
- Context: the background it can't guess. Paste the document, describe your situation, state your constraints.
- Format: what the output should look like. "A bulleted list, plain English, max 200 words."
- Quality bar: examples or criteria. "Match the tone of the sample below."
Before and after
Before: "Write a product description for my candle."
After: "Write a 60-word product description for a hand-poured soy candle (scent: fig and sea salt, price £24) for an audience that buys premium homeware. Warm but not gushing. Avoid the words 'elevate' and 'indulge'. Here are two descriptions whose tone I love: [examples]"
The second prompt takes ninety seconds longer to write and saves four rounds of "no, not like that."
Three habits worth building
Iterate instead of restarting. The conversation is the tool. "Closer. Make the middle paragraph more concrete, and cut the cliché in the opener" beats starting over.
Ask the model to interview you. When you don't know what context matters, flip it: "Ask me five questions that would help you do this task well, then do it." This one habit fixes more bad outputs than any other trick.
Request reasoning on hard problems. For analysis, maths, or anything with a right answer, add: "Think step by step, then give your final answer." You'll catch the model's mistakes in its visible work, and there will be fewer of them.
What not to bother with
You don't need to be polite (though it costs nothing), you don't need magic incantations, and most "1,000 best prompts" lists are padding. The durable skill is the same one good managers have: give clear briefs, share context generously, and give specific feedback. Master that, and every model gets better at the same time, whichever chatbot you choose.
