A prompt is a brief

The model can't read minds. It works with exactly what you wrote. So the quality of the answer depends almost entirely on the quality of the request — the prompt. The same question, phrased differently, gives anything from useless to excellent.

A good prompt isn't a "magic spell" or a set of secret words. It's a clear brief: what to do, for whom, in what form and to what end. If you can brief a person, you're already halfway to writing prompts.

See? A vague request forces the model to ask again or guess — and it often guesses something other than what you meant. Remove the ambiguity and you get the right result right away.

Why this matters more than it seems

Most disappointment with AI ("it gives clichés", "it doesn't get me") is really a prompt problem, not a model problem. The good news: it's a skill that improves fast. Small changes in wording give a disproportionately large jump in quality.

What's in this course

We'll cover clarity, context and examples, roles and style, step-by-step thinking, output format, ready-made templates and error analysis. By the end you'll get what you need in 1–2 tries, not ten.

Rule #1: if a person couldn't understand the task from your text, neither can the model. Write as if briefing a capable assistant who doesn't know your context.
