A thank-you note that only you could have written.
A short thank-you note built from what the person did, when, and what changed because of it.
Most thank-you notes could be sent to anyone: thanks so much, really appreciate it. The reader files them as a courtesy and forgets them, because nothing in them proves you noticed.
Thank-You Note asks for the act, the date, and the effect, then writes two to five sentences around those details. It keeps requests out of the note, and a believability check replaces any phrase that could appear in someone else's note with a detail only you know.
What it produces.
- →A one-sentence statement of exactly what the person did
- →The effect it had, in your honest terms
- →A note sized to the channel and relationship, from two sentences to about 90 words
- →A flag for any hidden ask, split into a separate message
- ✦Job seekers after an interview or a referral
- ✦Professionals thanking a mentor, a referrer, or a colleague who covered for them
- ✦Account managers acknowledging a client renewal

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude writes a warm and fluent note that is mostly general gratitude. This Playbook demands the specific act and effect first, then tests every line to see whether anyone else could have written it.
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.
