THE CONTEXT BUDGET CARD — the LSC-1 face
THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE CONTEXT BUDGET CARD · the reading seat · measure first, read only what you need

WAKES WHEN opening a big file, a long log or a large output; a long working session that is filling up; searching inside a big file for one place; picking the work back up after a break

THE LOOP

  1. NAME — say: "This is THE CONTEXT BUDGET CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
  2. MEASURE — `python3 scripts/budget.py measure FILE` — and follow the verdict.
  3. PEEK — `python3 scripts/budget.py peek FILE --head 40 --tail 20` or `--grep "pattern" --around 3`.
  4. SQUEEZE — `python3 scripts/budget.py squeeze run.log` for long logs.
  5. CHECKPOINT — `python3 scripts/budget.py checkpoint STATE.md --goal "..." --done "..." --next "..." --file F`, before the session fills, and read it first when you come back.
  6. LEDGER — write the ledger line.

NEVER

  • a big file read whole
  • a long output pasted in full
  • a session run until it forgets

CITE THIS CARDTHE CONTEXT BUDGET CARD, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=context-budget-card. Punch B7B4E09DBBABC7F4E6C6441F. Retrieved 2026-10-10.

What it is.

A seat for reading like a professional: measure a file before opening it, read only the part you need, and checkpoint before the session fills.

Measures files and estimates their tokens, shows only the lines you need, collapses repeating logs, and writes a checkpoint to come back to.

Its laws, written into the card.

  • Measure before you open. A big file read whole crowds out everything else the session knows.
  • Read the part you need: the head and tail, or the lines around a match. Count what was left out, and say so.
  • Long lines and long logs are cut and collapsed, never pasted whole.
  • Checkpoint before the session fills: the goal, what is done, what is next, and each file's hash.
  • Token counts here are estimates and are called estimates.

How it works, once your AI has it.

  1. NAME — say: "This is THE CONTEXT BUDGET CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
  2. MEASURE — `python3 scripts/budget.py measure FILE` — and follow the verdict.
  3. PEEK — `python3 scripts/budget.py peek FILE --head 40 --tail 20` or `--grep "pattern" --around 3`.
  4. SQUEEZE — `python3 scripts/budget.py squeeze run.log` for long logs.
  5. CHECKPOINT — `python3 scripts/budget.py checkpoint STATE.md --goal "..." --done "..." --next "..." --file F`, before the session fills, and read it first when you come back.
  6. LEDGER — write the ledger line.

When it says no.

  • A big file read whole.
  • A long output pasted in full.
  • A session run until it forgets.

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 778 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.
