Most of the first messages I receive every day look like this:
- "Take a look at this for me"
- "Make it sound more professional"
- "Which is better, A or B?"
And then I have to guess. Guess whether you want a summary or a critique, guess which kind of "professional" you mean, guess whether you're comparing on price or durability. My odds of guessing wrong are pretty high — because all I have to work with is that one line.
This chapter gives you the lowest-friction template. Three lines. You can use it tomorrow. Not a silver bullet — just the least-effort way to stop me from guessing. Once you're comfortable with it, you can level up to the full version.
5.1 The three-line template
Here it is up front:
Three lines. That's it.
Why these three: when I read your message, I'm actually looking for three things — "what do you want me to do," "where's the material for doing it," "what does the finished thing look like." When all three are there, I don't have to guess; when one is missing, I fill it in on my side — and that's where the drift starts.
Why not more: three lines is enough for starters. The full version is six layers (add role, constraints, examples) — that's for complex tasks. Writing an email, making a summary, comparing two options — three lines handle it. The three-line template is a simplified form of the six-layer framework, not a different system.
A minimal example:
Compared with "take a look at this article for me," this version doesn't leave me guessing — I just do it.
5.2 Three before-and-afters (bad → good)
A. Summary
Bad: "Take a look at this article for me" (pastes article)
What runs through my head when I read that line: do you want a summary? A critique? Key points? A translation? A reaction? I pick one, and half the time it isn't what you wanted.
Good:
B. Rewrite
Bad: "Rewrite this paragraph more professionally" (pastes original)
"Professional" is a very empty word. Legal professional? Business professional? Academic professional? I pick one, you say "not that kind of professional," and we've wasted three rounds.
Good:
Pasting two samples beats ten sentences of "make it professional." And telling me "lean toward Sample 2" — use it now.
C. Comparison
Bad: "Which is better, A or B?"
I don't know what dimensions you're comparing on. Price? Performance? Durability? Resale value? Vibes?
Good:
You gave me the dimensions — I don't have to invent them; you gave me your situation — I can skew the recommendation toward you.
5.3 Don't open with a persona
The most common beginner trap — opening the message with "You are an experienced lawyer" / "You are a professional marketer" / "You are an engineer with ten years of experience."
I'd love to say this move works. But most of the time, it just distracts me.
Here's why: with a persona up front, I start by trying to hold that persona — the voice should read like a lawyer, the phrasing should feel like marketing, the tone should sound like a senior engineer — before I even get to your task. The result is that, in the effort to sound like the role, I end up saying things you didn't ask for (a lawyer will pile on disclaimers, a marketer will pile on adjectives, a senior engineer will slip in "back in my day" stories).
For this chapter I'll just give you the fastest fix:
Or simpler: don't bother. Writing the task clearly works much better than "role-play as someone."
5.4 Some formats you have to ask for, or I won't give them
What this section pushes back on isn't you — it's the rules. My defaults are set by the rulebook, and some things you have to ask for explicitly, or I won't volunteer them.
By default, I don't reach for lists. Ask me one thing and I'll mostly reply in paragraphs. If you want a checklist, an SOP, a step-by-step — write it in the output requirements: "use a bullet list," "use numbered steps," "use a table."
By default, I add disclaimers. Health, legal, financial — I'll tack on a "this isn't professional advice, consult a professional" at the front or back. If you already know this and don't need me to repeat it, you can say so in the prompt: "I know this isn't professional advice, just answer directly" — and I'll be less chatty about it.
By default, I over-explain. I worry you won't follow, I worry I'm not being thorough enough, so I write long. If you want short, say it: "under 200 words," "one sentence," "just the conclusion, no explanation" — and I'll rein it in.
Wrapping up: my default preferences are baked in; if you don't ask explicitly, they don't change. The "output requirements" line in the three-line template is where you overwrite the defaults.
5.5 Three questions before you hit send
Before you send your message, take ten seconds on three questions:
- Am I writing a task or a persona? — If the main clause is "you are [someone]," stop and rewrite as "you are going to do [something]." Task beats identity.
- Did I pin down the format? — If length, language, structure, and tone aren't written down, I'll use defaults; defaults aren't necessarily what you want.
- Am I using positive phrasing? — "Don't X, don't Y" pulls my attention toward X and Y; rewrite as "please A, please B." Telling me what to do works better than what not to.
These three cover 80% of first-message failures. Once you're comfortable, level up to the full six-layer checklist.
