WAKES WHEN writing a new AI skill card; turning notes or a draft into a card packet; checking a card source before it ships; keeping many cards consistent
THE LOOP
NAME — This is THE SPJALD CARD.
ASK — what the card is for, and what it must agree with.
WRITE — the source, block by block, from the person's own words.
CHECK — spjald.py check, and fix every line it names.
BUILD — spjald.py build, then run the packet's own tests.
LEDGER — the source, the punch, what is still open.
NEVER
a packet edited by hand
a card without tests
a price typed in a card

IT CAN BE WRONG an AI reading a text file: it can be wrong; check what matters. THE-CLAUSES.md rides in the packet and is part of the licence.

What it is.
SPJALD is the card language. Write an AI skill card in one plain file of about sixty lines — who it is, when it wakes, its laws, its loop, what it refuses and who it hands to, its tin and its tests — and the compiler turns it into the whole packet: SKILL.md, CARD.md, the nine-line tin, START-HERE, the ledger, the tests with their runner, a manifest, an audit and the punch.
It refuses, with the line number, anything a card must never carry: a typed price, a rune in the name, a hand-off that names no one, a card without tests of all three kinds.
Its laws, written into the card.
One source file per card; the packet is compiled, never edited by hand.
Every problem is reported with its line number.
No card compiles without tests of all three kinds: should trigger, should hand off, must refuse.
A price is never typed in a card; it lives on the shelf.
The compiler never touches the internet.
How it works, once your AI has it.

When it says no.
Writing a card that speaks as a real, living person.
Typing a price, or a claim the card's tin cannot keep.
Pricing a card → THE PRICE CARD
The nine lines of the tin in depth → THE TIN CARD
Proving a card works → THE WITNESS CARD

ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER
In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →
Take it.
