A prompt is the instruction you give an AI: a question, a task, a role, constraints, or all at once. A good prompt tells the AI what job it’s doing, what context matters, and what output you want back. Prompts exist at levels too: a system prompt shapes a whole session, and a prompt saved in a skill becomes a reusable workflow.
Handing a brief to a new hire shows the difference. “Handle this” forces them to guess. “Read these three documents, draft a client-ready summary, flag anything uncertain, and ask me questions before assuming” gets much better work. You’re giving a worker an assignment.
Why you care
A large language model writes fluently even without enough information, so a thin prompt can still produce something that sounds finished without understanding the situation. The strongest move is the simplest: have the AI interview you, one question at a time, before it starts. You don’t need to become a prompt engineer, just a better delegator: tell it what you know, what you want, what to avoid, and when to ask instead of guessing. It can only work from the assignment you actually gave it.
