One page a team can start on without a clarifying call.
A creative brief built from your project, goal, and audience: one objective, one reader, one message, and clear boundaries.
Weak briefs describe the project instead of directing it. They give the product, the deadline, and a mood word, and leave the maker to guess who it is for and what it should achieve. The first draft comes back polished and aimed at the wrong person.
Creative Brief forces the choices a client usually avoids: the objective in one sentence, the audience as a single person, the one message with its proof, the mandatories and the no-go list, and how success will be judged. It then tests the page by asking whether a stranger could begin tomorrow.

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude produces a tidy brief that restates your project in nicer words. This presses you for the audience, the single message, and the no-go list, and flags any line a maker would need to call you about.
How is this different from a Tool?
Playbooks are systematically produced to a fixed template and priced accordingly ($12.99). Tools are hand-built, one at a time, and go deeper ($39 to $199). A Playbook gives you a reliable method for routine work; a Tool is for when the judgment matters more than the format.
Will this work with ChatGPT, Gemini, and other LLMs?
Yes. You get a native Claude Skill (.zip) that auto-invokes in Claude, plus a plain .md you can paste into a ChatGPT Custom GPT, a Gemini system prompt, or any LLM. The procedure travels with the file.
Can I share this with my team?
It's licensed for your own personal and professional use. The output it produces is yours to circulate. To put the Playbook itself in the hands of a whole team, email hello@authority.md about team licensing.
What if it doesn't work for me?
If the file hasn't been delivered, or arrives defective or empty, we refund in full: see our refund policy.
