One launch, one message, three channels that agree with each other.
Announcement drafts for email, a blog or changelog post, and social, all built from a single core message and a list of true claims.
Launches get announced three times in three ways. The email promises a feature the blog says is coming soon, and the social post describes how hard it was to build. Readers learn nothing about what they can now do.
Launch Announcement writes the core message first, then lists every claim and what is live today. Email, post, and social drafts are cut from that one source, followed by a consistency check that catches the sentence that overpromises.

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude produces an excited announcement for each channel separately, and they drift apart. This fixes the message and the claims list first, writes each channel from it, and compares all three at the end for the same date, benefit, and action.
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.
