The anatomy of a working prompt

A reliable prompt has six components, and naming them turns prompting from guesswork into assembly. Role sets the perspective the answer comes from. Task states the single thing to produce. Context supplies the facts. Audience says who reads it. Constraints fix length, format, tone, and prohibitions. Success criteria describe what a good answer contains. You will not always need all six, but when output disappoints, the fault is almost always a missing component rather than a bad tool. Order and separation matter more than eloquence. Put the task early so it is unmistakable, then the context, then the constraints, and use plain labels or line breaks between blocks. A prompt written as one long run-on paragraph invites the tool to weight the wrong parts. Labeled blocks — Task, Context, Constraints, Output format — read like a work order, and work orders get filled correctly far more often than conversations do. One component is chronically neglected: output format. Saying exactly what shape you want back — "three options, each with a one-line rationale" or "a table with columns for step, owner, and deadline" — eliminates most reformatting work and makes review faster. It also constrains the content, because a format forces the tool to commit to specifics rather than drifting into general advice. Prompts fail in predictable places, and diagnosing them by component is faster than rewriting from scratch. Vague output means thin context; wrong shape means no output format; wrong emphasis means the task was buried in the middle. Success criteria are the most advanced component and worth adding once the others are habitual. Stating what a good answer contains — for example, "names the deadline and the owner of each step" — gives the tool a target to hit rather than a style to imitate. An operations manager cut her prompt-fixing time in half by keeping the six component names on a sticky note and checking them one at a time whenever an answer disappointed her.

Key takeaways

• Order and separation matter more than eloquence.
• One component is chronically neglected: output format.
• Most people state the task and a tone but never the shape, which is why so much output needs reformatting before use.
