Stop Writing Vague Prompts: A Refiner's Checklist

Most disappointing AI output traces back to a vague prompt, not a dumb model. "Write me something about marketing" gives you beige filler because you left every meaningful decision to chance. Specificity is the single highest-leverage edit you can make — and it takes about thirty seconds.

Here's the checklist we run before sending anything that matters.

The ten-second sharpening pass

• Who is this for? Name the audience. "For first-time founders" produces very different copy than "for CFOs."
• What's the one goal? Replace "about X" with "that does Y." A prompt should have a verb.
• What does done look like? Length, format, structure. "Five bullet points, under 15 words each."
• What's the tone? Plain, playful, formal, urgent. Don't make the model guess.
• What must it include? The non-negotiables — a specific example, a data point, a call to action.
• What must it avoid? Jargon, clichés, a competitor's name, hedging.
• What's the context? What's been tried, what failed, what you already know.
• Any constraints? Reading level, word count, a format the downstream tool needs.
• Is there an example? One sample of good output beats a paragraph of description.
• Should it self-check? "Flag anything you're unsure about" surfaces weak spots instead of hiding them.

You won't need all ten every time. But if the last answer was mushy, walk this list and you'll usually find two or three you skipped.

Turn the checklist into a habit

The fastest way to internalize this is to let a tool do it a few dozen times so the pattern sticks. Our AI Prompt Refiner applies exactly these checks — it takes a vague one-liner and asks the clarifying questions this list implies, then rewrites the prompt with them answered. After a couple of weeks you'll start writing the sharp version first.

If you'd rather learn by example, browse prompts that are already specific and notice why — the audience, the format, and the constraints are always right there in the text. Vague is a habit. So is specific. This checklist just makes the good habit the easy one.
