Prompt Engineering: Stop Writing Paragraphs

The structure\n\n```\nRole: who the model is\nInput: the raw material\nTask: the single job\nFormat: exact output shape\nConstraints: what to never do\n```\n\nEverything else is decoration. Once the structure is stable, iterate on constraints only — that is where quality lives.\n\n## Worked example\nWe take a vague brief and tighten it three times, measuring how much editing the output needs each round.
