THE DECK · AFTER YOU BUY
You’ve got your card. Here’s how to put it to work.
Your card is one file ending .skill.zip. It reaches you two ways: a Download button on the page you land on after paying, and an email headed along the lines of “your downloads are ready” — a second email, separate from your order confirmation. If it is not there in ten minutes, look in spam.
DO THIS ON A COMPUTER, NOT A PHONE · NOTHING RENEWS ITSELF · THE FILE YOU HOLD KEEPS WORKING AT ITS EDITION
Four steps
- Download it from the button or the email. Keep it as it is — do not unzip it for Claude.
- In Claude: open Customize → Skills, press +, then Create skill, and upload the
.skill.zip. Skills need code execution switched on in Claude’s settings. - Start a new chat and say the card’s name — for THE RUNNER, type THE RUNNER. It answers in the first person and asks about you.
- In ChatGPT, Gemini or another AI: unzip the file and open
START-HERE.md— it shows which file to paste where. On your own computer,card.htmlis the whole card as one page, offline.
Check it is the real one
Every card carries a punch: the first twenty-four characters of the fingerprint of its own door file, printed under the dot grid on its face. THE RUNNER’s is DD36317FD363D43657140832. The same characters are on its page here and inside the file you downloaded.
Check any card file
Pick a file ending .skill.zip — from your order email, a download button, or anywhere a file claiming to be ours came from. This page opens it on your own computer, hashes its door file and looks the punch up in the house's table of every card it has cut. Nothing is uploaded; nothing leaves your machine.
A MATCH NAMES THE CARD AND ITS NUMBER · NO MATCH MEANS CHANGED SINCE IT LEFT, ANOTHER EDITION, OR NEVER OURS · WHEN IN DOUBT, GET THE FILE AGAIN FROM YOUR ORDER EMAIL AND TELL THE STUDIO
If something is missing
No email and no button: reply to your order confirmation and the studio will send the link again. A download that has stopped working: the same. During your term, new editions arrive by email as replacement files — nothing reaches into what you already hold.
HAVE A FILE ENDING .SEALED INSTEAD? OPEN IT HERE
Some cards are delivered sealed, with a key in the order email. Pick the file, paste the key, and it opens in this page, on your own computer; nothing is uploaded.
