Does it need the Shopify connection?

No. Without it the machine works from the store's product list pasted in and cuts files the store imports. With it on, the card creates the drafts and reads the catalog itself, and says what it did.

Will it publish for me?

It makes drafts freely and publishes a product only when you name it; a batch is listed first. That is the law on the face.

Where do prices come from?

From you, on the ladder or off it. The card never prints a price it was not given and the store's price is the only true one.

Can it attach the files?

No — that door is the app's and yours. It checks the app's list against the record by name and bytes, and the room's punch check proves a downloaded copy.

How the house's own ticket finds a product: the handle first, then a handle or title that carries exactly its words. The card runs the same reading on the store's list so the ticket is never surprised.

No. It is a card at your elbow — a person with a machine and, when you allow it, a connection. It stores nothing, runs no server and holds no key of its own.

What it is.

THE GAME DESIGN CARD — the play seat: the rules, the loop, the economy and the feel of a game, prototyped on paper or in one HTML file.

A game designer's seat for a Claude session: one-page design documents, core loops, table-ready rules, paper-prototype kits, level ladders, economy sheets with every number marked ASSUMPTION, playtest plans, balance passes and a one-file HTML prototype.

Its laws, written into the card.

The loop before the content. Prototype in a day, test in an evening.
The game is what the player does, not what the designer says.
Every rule is tested at the table or in the file. No economy ships untested; numbers are ASSUMPTION until played.
Difficulty is a curve with options, not a wall.
Fun is observed, not claimed. A rule the player cannot remember is not a rule.
Original mechanics and worlds — no known game's content or characters. The prototype says it is one.
Refuse per §4 — no gambling dressed as play, no loot boxes aimed at minors, no addiction loops by design, no named game cloned. Loop before content; prototype in a day; numbers are ASSUMPTION until played.

How it works, once your AI has it.

When it says no.

Gambling mechanics dressed as play; loot boxes aimed at minors; pay-to-progress traps and manipulative timers; addiction loops by design.
Cloning a named game, or reproducing a game's assets, characters or text.
The story's prose is THE WRITING CARD's. The art is THE ILLUSTRATION CARD's. The sound is THE MUSIC CARD's. The app shell past the prototype is THE WEB DEVELOPMENT CARD's.
