Four Ingredients to Better Prompting

Last week we looked at why "write an email to an overdue customer" comes back as something you would never send. The short version: a vague request leaves the model guessing, and its guesses land on the most average version of every answer.

This week is the practical follow-up. Good prompts are not secret phrasings or magic words. They are recipes, and the ones that work contain the same four ingredients every time. Once you can name all four, you stop rewriting bad answers and start fixing the request that produced them.

The Four Ingredients

Every prompt worth saving has a role, context, a task, and a format. Order does not matter much. Presence does.

• Role. Who is doing the writing and who is receiving it. "You are the owner of a three-truck plumbing company writing to a homeowner who has used you twice before."
• Context. The facts about your situation the model cannot know. Names, amounts, dates, history, what you already tried, what went wrong last time.
• Task. The single job you want done, stated as one instruction rather than three stacked on top of each other.
• Format. What the finished thing should look like when it lands. Length, tone, structure, and the specific things you never want to see in it.

Most people who find AI tools underwhelming are writing prompts with exactly one ingredient in them. Usually the task, standing alone, with nothing else attached.

That same Federal Reserve survey found that writing and marketing is what 83 percent of AI-using small firms use the tools for, by a wide margin the most common application. Those two findings belong together. Writing is where prompt quality shows up fastest, because a wrong fact or a tone that misses is obvious the second you read it back.

What Each Missing Ingredient Breaks

The useful part of a four-part recipe is diagnosis. When an answer comes back wrong, the way it is wrong tells you which ingredient you skipped.

No role, and the answer has no voice. It reads like a press release from a company with no employees. You will recognize this one because you cannot picture anybody saying it out loud. Fixing it takes eight words: "You are the office manager at a small dental practice."

No context, and the answer is technically fine and practically useless. It addresses the general version of your situation. The email to your overdue client does not mention that this is the first time in four years he has been late, because you never said so, and that single fact was the whole reason the email needed a different tone.

No task, and you get an essay when you wanted a decision. This happens more than people expect. "Help me with our cancellation policy" is a topic. "Draft a two-sentence cancellation policy for our booking page that mentions a 24-hour window and a $35 fee" is a task.

No format, and the answer is the right content in the wrong shape. Six paragraphs when you wanted four sentences. Bullet points when you wanted prose. A closing line you would never write. Format is the ingredient people skip most often and the one that saves the most rewriting.

Putting It Together

Here is the same job written both ways.

One ingredient: "Write a follow-up for a customer who got a quote and didn't respond."

All four: "You are the owner of a residential landscaping company in a small town. Two weeks ago I quoted Janet Reyes $4,800 for a backyard patio installation. She said she liked the design and would talk to her husband. I have not heard back. Write a single follow-up email that gives her an easy way to say no, mentions that our September schedule fills up around the 20th, and does not push. Under ninety words, warm and plain, no exclamation points, do not use the word 'circling.'"

The second one takes maybe forty seconds longer to type. It comes back ready to send. The first one comes back as a template you then spend six minutes turning into something true.

Notice that none of the added material is clever. It is all information you already have in your head. The work of prompting is mostly the work of writing that information down instead of assuming it came across.

The Ingredient People Argue About

Some people will tell you the role line is theatre and does nothing. In practice it does two things worth keeping. It sets vocabulary, so a prompt written from the perspective of a bookkeeper produces bookkeeping words rather than marketing words. And it sets a point of view, which matters enormously when the output is something a customer will read.

Where the skeptics have a point is length. A role line should be one sentence. Three paragraphs of elaborate character description does nothing that "you are a veterinary office manager" did not already do, and it buries the context that actually matters underneath it.

What to Do Next

Take the four ingredients out for a test drive this week on work you were going to do anyway.

1. Rewrite one prompt you already use. Find the last AI answer you had to fix by hand. Add whichever of the four ingredients was missing, run it again, and compare.
2. Write one recipe down and keep it. The follow-up email, the review response, the customer update. One is enough to start a library, which is where this series ends up in Part 5.
3. Take the AI Readiness Assessment. Four minutes, no signup. It shows which of the tasks eating your week are the best candidates for AI help, so your prompting practice pays back on work that actually matters.

Prompting well is not a talent and it is not a trick. It is the discipline of writing down four things you already know before you ask for help: who is speaking, what the situation is, what you want done, and what the finished thing should look like. Next Monday, Part 3 covers the small adjustments that separate a prompt that works from one that works every time.
