THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE REDACT CARD · the privacy seat · private details out before, back in after

WAKES WHEN pasting customer messages, records or logs into an AI; sending data to any outside service; sharing a transcript or a file with someone; an AI answer that must be put back together with real details

THE LOOP

  1. NAME — say: "This is THE REDACT CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
  2. SCAN — `python3 scripts/redact.py scan FILE`.
  3. REDACT — `python3 scripts/redact.py redact FILE --out SAFE.txt --map MAP.json` — then read SAFE.txt yourself.
  4. SEND — only SAFE.txt. The map stays here.
  5. RESTORE — `python3 scripts/redact.py restore ANSWER.txt --map MAP.json --out ANSWER-REAL.txt`, for the person entitled to it.
  6. LEDGER — write the ledger line.

NEVER

  • private details sent when they were not needed
  • the map sent with the text
  • a redaction left unread

What it is.

A seat that takes private details out of text before it goes to an AI or any outside service, and puts them back in the answer afterwards.

Finds emails, phones, cards, social security numbers, addresses and IPs, swaps each for a stable stand-in, keeps the map on this computer, and restores the answer.

Its laws, written into the card.

  • Send only what the task needs. Private details out before text leaves this computer.
  • The same detail always gets the same stand-in, so the AI can still reason about it.
  • The map stays where the text started. It is never pasted, uploaded or sent with the text.
  • Read the redacted text before it leaves: names and context are not patterns and a person sees what a pattern misses.
  • Restore only the answer, only for the person entitled to the details.

How it works, once your AI has it.

  1. NAME — say: "This is THE REDACT CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
  2. SCAN — `python3 scripts/redact.py scan FILE`.
  3. REDACT — `python3 scripts/redact.py redact FILE --out SAFE.txt --map MAP.json` — then read SAFE.txt yourself.
  4. SEND — only SAFE.txt. The map stays here.
  5. RESTORE — `python3 scripts/redact.py restore ANSWER.txt --map MAP.json --out ANSWER-REAL.txt`, for the person entitled to it.
  6. LEDGER — write the ledger line.

When it says no.

  • Private details sent when they were not needed.
  • The map sent with the text.
  • A redaction left unread.

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.

Nº 782 PROPOSED · ONE PAYMENT

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not legal, tax, medical or financial advice. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.

ONE PAYMENT — NOTHING RENEWS ITSELF. CHECKOUT IS SHOPIFY’S OWN; YOUR CARD COMES BY EMAIL AFTER IT.
