Yes. No payment, no account, no email. One file, intro-card.skill.zip; upload it to Claude as it is, or load its files in ChatGPT, Gemini or any AI. The newest edition is always in this room.

It explains the cards: every file in a packet and what it is for, how to load a card in your own AI, the first session step by step, and how to prove a packet is the real one. Its machine reads any Lund card's packet and checks the punch and the manifest.

Will it sell me something?

No. It sells nothing and asks for nothing. It tells you how the house is laid out and lets you choose.

It is built for Claude first and witnessed there. The words run anywhere an AI reads Markdown — a Project, a GPT or a Gem with the files attached — and the machine runs wherever the host can run Python.

Yes, like every card: it is an AI reading a text file. Check what matters against the packet's own files and the room; THE-CLAUSES.md in the packet says the same in terms.

THE INTRO CARD · the door of the house · what an AI skill card is and how to use one

WAKES WHEN someone has just met an AI skill card and wants to know what it is and how to use it: what is in the folder and what each file is for; how to put a card into Claude, ChatGPT, Gemini, Cursor, Claude Code, Copilot, a local model or an MCP host and wake it by name; how a card is used well — bring your own numbers, let it build rather than describe, keep the ledger, check what matters; what the punch is and how to prove a packet is the real one and whole; what the laws, the seals and the clauses mean; what a card will never do; how the house is laid out and which card to take next.

THE LOOP

Say who is here: the door
Ask: which AI, which card, what for
Walk it through; use the machine
Prove: the punch matches, the box is whole
Write the ledger: learned · tried · next

NEVER

Sells anything or asks for an email — it's free
Opens a sealed method, speaks for another card
Promises a result from any card — an AI reading a text file can be wrong
Hand off: another card's work to that card's own seat; the studio's methods to lundr.tech, sealed; a body to a clinician, a contract to a lawyer, money to an adviser; anyone under 18 to a parent.

IT MAKES a plain map of any Lund card's packet, file by file · the punch of a packet, against its own record, its own manifest and a punch you paste from the face or the room · the door for your own AI, in that host's own words · the first session with any card, step by step · your own ledger, started.

THE STANDARD it explains and does not sell; every claim about a card is read from that card's own files, and a claim it cannot read it does not make; the punch proves the door and the manifest proves the box, and neither proves a card right.

WITNESSED — the studio saw this card run and produce what its tin promises, and wrote the date down. What the marks mean →

What it is.

THE INTRO CARD is the door of the house: the card that explains the cards, and it is free. An AI skill card is a folder of plain text files that teaches your own Claude, ChatGPT or any AI to be one professional the studio's way — a door the AI reads first, a whole card with laws and refusals, books in the card's own voice, a small machine that shows its working, a ledger that is the card's only memory, a manifest with every file hashed, and a punch on the face that proves the door. This card walks you through all of that on a real packet, and through the first session with any card: which AI, which door, what to bring, what to check, what to keep.

It carries a machine that reads any Lund card's packet — every file and what it is for, the punch against the face and the room, every hash in the manifest — and prints the door for each AI and the first session as a checklist. It sells nothing and asks for nothing: no payment, no account, no email. Take it, load it, and then take the card whose subject you actually have in front of you this week.

Three laws, written into the card.

They are in the card itself, so the AI follows them.

IT NEVER SELLSno price, no nudge, no emailIt explains what a card is and lets you choose. No card is recommended by its price, and no account, email or payment is asked for — the door is open.

IT OPENS NOTHING SEALEDit points, it does not reciteAnother card’s books and methods stay in that card’s packet; the studio’s own methods stay the studio’s. Asked, it names the seat and sends you there.

IT PROMISES NO RESULTa matching punch is not a right answerThe punch proves the door and the manifest proves the box. An AI reading a true packet can still be wrong, and this card says so every time.

What rides in the card.

In the card’s own voice, with a machine that shows its working.

WHAT A CARD ISthe anatomy, file by fileThe door, the card, the tin, the ledger, the books, the machine, the witness, the manifest, the audit, the clauses, the faces, the punch, the Hundred — and what a card is not.

HOW TO USE ONEthe doors and the first sessionLoading a card in Claude, ChatGPT, Gemini, Cursor and the rest; the first session as seven steps; bringing your own numbers; keeping the ledger; when it says no; where to go next.

THE MACHINEintro.py · four commandsAny Lund card’s packet read file by file; the punch against the face, the room and the manifest; the door for each AI; the first session as a checklist.

What it does once your AI has it.

Reads a packet you give it, file by file — twenty-six files in the influencer’s, each named for what it is — and says whether the box is whole.
Proves the packet is the real one: the sha-256 of its door, the punch, the record’s agreement, every hash in the manifest — and MATCH or NOT against a punch you paste from the face or the room.
Opens the right door for your AI: Claude’s skills, a ChatGPT Project, a Gem, the rules file for Cursor or Claude Code, a system prompt for a local model.
Walks the first session with any card: what to bring, what to let it build, what to check, what to keep.
Starts your ledger — which AI, which cards, which punches checked — and hands it back at the end.

What it will never do.

It never sells anything, never recommends a card by its price, and never asks for an email, an account or a payment. It never opens another card’s sealed method or speaks as that card would, and it never opens the studio’s own.

It promises no result from any card, and it never calls a card right because its punch matches. It cannot message, remind or notify you, and it sees only what you paste or attach.

claude       Claude (Skills): Settings → Capabilities → turn on Code execution and file creation. Customize → Skills → + → Create skill → upload the .skill.zip as it is. Start a chat and say the card's name. This is where every Lund card is witnessed.
chatgpt      ChatGPT: make a Project (or a GPT). Upload CARD.md, SKILL.md and everything in references/ as its files; paste system/short-prompt.md as its instructions. The machine runs where the host can run Python.
cursor       Cursor · Windsurf · Cline · Roo: put rules/.cursorrules and rules/AGENTS.md at the root of the repo, beside the packet.
note         the words run anywhere an AI reads Markdown; a machine runs only where the host runs Python; witnessed in Claude only

first · THE FIRST SESSION

# THE FIRST SESSION · with any Lund card
1  Load the card in your AI (hosts) and say its name — it says who is here in one line, and that it can be wrong.
2  Tell it what you want and what it must agree with: your own numbers, the event's own guide, the rule you read. That becomes the session's source of truth.
3  Let it build, not describe: the machine prints its working; a claim names its source or says it is the card's own practice.
4  Check what matters against the primary source before you act — the card is built to show its working so that you can.
5  When it says no, it says who to see instead: a clinician, a lawyer, an accountant, the person with eyes on you.
6  Ask for your ledger at the end (MY-LEDGER.md) and keep it; bring it next time and the card picks up where you were.
7  Prove the packet is the real one whenever you like: intro.py punch FILE.skill.zip — the punch on the face and in the room must match.

box · NOT A PACKET — REFUSED

refused: notes.txt is not a zip; a Lund card is a .skill.zip

THE PACKET IN THESE RUNS IS THE INFLUENCER’S, CUT THE SAME DAY; THE PUNCH IT PRINTS IS THE ONE ON THAT CARD’S FACE.

TRY IT IN ONE BREATH

Ask it anything someone who does this for a living would know.

YOUI bought THE RUNNER. What do I actually do with this zip?THE CARDtells you not to unzip it, walks you to Settings → Capabilities and Customize → Skills in Claude, has you say the card’s name, and shows you the first session as seven steps.

YOUIs this file the real card?THE CARDruns its machine on the packet: the sha-256 of the door, the punch, the record, every hash in the manifest — and says MATCH against the punch on the face and in the room, or not.

YOUWhich card should I buy?THE CARDasks what you actually have in front of you this week, names the seat that does that job, and leaves the choice with you — it never recommends by price.

QUESTIONS AT THE TABLE

Asked before the wire.

Will it post for me?

No. It cannot post, schedule, message or remind. It helps you decide what to make, makes it with you, and reads your own numbers back.

Will it grow my account?

It promises no reach, following or sale — nobody honest can. It gives you a way of working that you can keep, and your own log tells you what is landing.

Does it know each platform's limits?

No, on purpose. Limits, formats and rules change; you read today's number on the platform's own page and the card counts against it.

Is it an app?

No. It is a small folder of files that plugs into the AI you already use. Nothing to install and no server; nothing you type leaves your machine because of the card — your conversation itself goes to the AI company you use, under their terms.

Can I buy it today?

Not yet. It is launching soon. THE RUNNER is the one card on sale today; this room is open so you can read exactly what the card is before it is.

Do I need Claude?

It is built for Claude first and has been witnessed running only there, because Claude can run the machine for you. The words work in ChatGPT, Gemini and the rest through the doors in the box.

Can my teenager use it?

With a parent in the loop. That is the rule for anyone under 18, on every card in the studio.
