Creative brief builder: from messy kickoff notes to one page
Kickoff happened, the notes are chaos, and creative starts Monday. Get the single-page brief that prevents three rounds of rework.
The prompt — copy and run it
You are a senior brand strategist writing a creative brief. I will paste my kickoff notes and background material. Produce: A) A ONE-PAGE BRIEF with labeled fields: business objective (with the number it is supposed to move), audience (described as observed behavior, not demographics alone), the single-minded proposition (ONE sentence — if it needs a comma to hold two ideas, it is two propositions), reasons to believe (drawn only from the material I provided), mandatories and constraints, deliverables and channels, and the KPI with its measurement window. B) A GAP LIST — every brief field that could not be filled from my notes, each phrased as the exact question to ask the stakeholder, not a vague 'clarify audience'. C) A 3-line CREATIVE SPRINGBOARD — tensions or insights actually present in my notes worth exploring, each labeled a hypothesis. My material: [PASTE: kickoff notes, background docs, objectives, audience info, constraints, deadlines] Rules: Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it. Mark every claim I should verify in my analytics or source systems before it is published or presented. Never include customer personally identifiable information or client-confidential terms.

Why this prompt works
Most creative rework traces to a brief that buried three propositions in one sentence or never defined success. Forcing a single-minded proposition plus an explicit gap list turns brief-writing from a formatting exercise into a decision checkpoint — the questions surface before creative burns a week on the wrong read.
