Prompt standards for creative work: one format for every brief

A prompt is a brief that a tool reads. When every writer uses a different format, the outputs cannot be compared, reviewed or reused.

Why a standard

  • The same request written three ways gives three outputs that cannot be compared.
  • A standard lets a colleague rerun the prompt and get output in the same style.

The fields every prompt has

  • Product: the name and one line on what it does, as the client writes it.
  • Audience and the problem the ad speaks to.
  • Angle: one of the agency's approved angles, not a new one for every request.
  • Allowed and forbidden claims, copied from the client's approved list.
  • Format: length, ratio or character limit, and the placement it is for.
  • Tone: three adjectives and one sentence from the client that they liked.

What stays out of a prompt

  • Personal data of customers, order details and anything under a confidentiality clause.
  • Keys, passwords, login details and private links.
  • Unreleased prices and campaign dates, unless the client agreed to share them with the tool.
Made-up scenario: a prompt named pdp-hook-v3 for a 6 second vertical hook has the product, the audience, the allowed claims and a 12 word limit filled in. A colleague runs it a week later and gets outputs in the same style.
Name each prompt and give it a version number, and write a change note with the reason each time it is edited.
