Overview

What Ad Creative Brief Writer does.

This skill takes four inputs — product, target audience, campaign goal, and channel — and returns a structured creative brief built around a single-minded proposition, an audience insight framed as a tension, written hooks ready for the two-second scroll test, angle variants for split testing, channel-specific format notes, proof and credibility elements, and a do/don't brand rules list specific enough to resolve creative disputes without a meeting. It forces the brief to one sentence before anything else, so designers and copywriters receive direction rather than vibes.

A buyer might input: a DTC supplement brand, audience of 35-50-year-old women who exercise but feel their recovery is slower than it used to be, goal of driving first purchase, channel Meta feed and Stories. The skill surfaces the tension ('they trust the effort they put in but no longer trust their body to bounce back'), then writes actual hook lines — not descriptions of hooks — and maps which angle to test first based on the channel's creative norms.

Sample output excerpt — Audience Insight: 'They train as hard as they did at 30 but wake up feeling like they didn't. The belief blocking purchase: supplements are for people who aren't disciplined enough.' Single-Minded Proposition: 'Recovery that matches your effort.' Hook A (curiosity): 'You haven't changed. Your recovery has.' Hook B (proof): 'Same workout. 40% less soreness. Here's what shifted.' Do: show real effort, never a spa. Don't: use the word 'wellness' — it triggers skepticism in this segment.

Who it's for

Performance marketers, in-house brand teams, and freelance creative strategists who brief designers and copywriters regularly and need to cut revision cycles caused by briefs that describe a mood instead of defining a job. Also useful for solo founders writing their own Meta or TikTok ads who lack a formal strategy process.

In depth

Why a Claude skill beats a prompt template.

A copy-paste prompt runs one static pass and stops. A skill is a bundled program — instructions, examples, and a workflow Claude runs as a unit: it asks for the right input, applies the same pattern every time, and returns the structured outputs above.

FAQ

Common questions.

What do I need to provide for the skill to produce a usable brief?

At minimum: what the product does, who you are targeting and what they currently believe, what action this specific ad should drive, and which channel or format it will run on. The more specific your proof points — a stat, a differentiator, a customer result — the stronger the credibility section will be.

Does it write the actual ad copy, or just the brief?

It writes the brief, including actual hook lines and angle variants — not descriptions of what the copy should feel like. A designer or copywriter can execute from the output without a briefing call, but the skill stops short of producing final production-ready ad copy or scripts.

Can I use it for multiple channels in one session, such as Meta and TikTok for the same campaign?

Yes. The Channel and Format Specifics section adapts to whichever channels you name. If you specify both, it will note where the creative approach diverges — for example, where a static hook translates to video and where it does not.

What format does the output arrive in — a document, a table, something else?

The brief is structured as a named-section document by default, with each section — proposition, insight, hooks, angle variants, proof, do/dont rules, visual direction — clearly separated so it can be dropped into Notion, a shared doc, or a PDF template without reformatting.

Is this useful if I am the only person on the campaign, with no separate designer or copywriter?

Yes. The brief functions as a decision filter for solo operators: it forces you to choose one job for the ad before spending on production, and the do/don't list prevents scope creep that wastes time and budget when you are making the asset yourself.
