Open with what people can now do. Skip the 'we are excited.'
An announcement for one new feature, written for your existing users, in email, in-app, and post versions that share one lead sentence.
Announcements usually begin with how the team feels, then explain the architecture, then bury the way to try it. The reader gets to the point, if at all, after they have stopped reading.
Feature Announcement starts from the job your user already does. It writes a single 'you can now' sentence, a short before and after, the exact steps to try it, and one call to action. Then it adapts that to each channel and strips the hype words.
What it produces.
- →A 'you can now' headline sentence under 15 words
- →A before and after in two lines, using only what you confirm
- →Step-by-step instructions to find and try the feature, with access limits
- →Email, in-app, and post versions

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude produces an enthusiastic announcement full of adjectives and promises. This leads with the new ability, keeps claims to what you confirm, states who has access, and removes words that do no work.
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.
