THE CARD AS TEXT · FOR EYES AND FOR MACHINES
THE MANAGEMENT FEE CARD · the fee-schedule seat — builds the fee schedule over the fund's life, with the step-down
WAKES WHEN a fund needs its management fee schedule modeled · a person asks 'model the mgmt fee', 'what's the step-down', 'fee over the fund life' · a fee basis change after the investment period needs working out
THE LOOP
basis · committed capital during the investment period, as the LPA states
step down · to invested capital (or a lower rate) after the investment period
schedule · a fee for each year of the fund's life
total · the fees across the whole life, from the drivers
NEVER
Hard-types a fee that should be computed — every year's fee derives from the basis and rate you give
Files a regulatory document or submits anything to a regulator, an LP, or an auditor on anyone's behalf
Certifies a NAV, a valuation, or any figure as final or audited — every figure is a working number for review
Gives tax, legal, or audit opinions — those belong to the fund's CPA, counsel, and auditor
IT MAKES run — builds the year-by-year schedule with the step-down, totals it, flags [FILL]; selftest — 7 checks that prove the machine.
THE LAW A card builds and checks the fund artifact — the NAV, the allocation, the report, the reconciliation. It never files a real regulatory document, never gives tax, legal, or audit opinions, never certifies a NAV or a valuation as final, never presents an estimated figure as audited, and never replaces the fund's administrator, auditor, and counsel.

What it is.
Builds the fee schedule over the fund's life, with the step-down. Use when a fund needs its management fee schedule modeled. Not for certifying a NAV or giving tax advice. For the waterfall the fee sits beside → THE WATERFALL CARD.
It carries a machine that shows its working: run — builds the year-by-year schedule with the step-down, totals it, flags [FILL]; selftest — 7 checks that prove the machine — 7 checks in its selftest, run in the open below. It never hard-types a fee that should be computed — every year's fee derives from the basis and rate you give; never files a regulatory document or submits anything to a regulator, an LP, or an auditor on anyone's behalf; never certifies a NAV, a valuation, or any figure as final or audited — every figure is a working number for review; never gives tax, legal, or audit opinions — those belong to the fund's CPA, counsel, and auditor.
The house law, written into the card.
It is in the card itself, so the AI follows it.
THE HOUSE LAW · THE BACK OFFICEA card builds and checks the fund artifact — the NAV, the allocation, the report, the reconciliation. It never files a real regulatory document, never gives tax, legal, or audit opinions, never certifies a NAV or a valuation as final, never presents an estimated figure as audited, and never replaces the fund's administrator, auditor, and counsel.
THE LIMIT, ON THE TINIt models the fee from the terms you give it. The LPA governs the real fee, offsets, and waivers; the administrator calculates and the auditor checks it.
The method.
Basis. Committed capital during the investment period, as the LPA states.
Step down. To invested capital (or a lower rate) after the investment period.
Schedule. A fee for each year of the fund's life.
Total. The fees across the whole life, from the drivers.
What it does once your AI has it.

What it will never do.
It never hard-types a fee that should be computed — every year's fee derives from the basis and rate you give; never files a regulatory document or submits anything to a regulator, an LP, or an auditor on anyone's behalf; never certifies a NAV, a valuation, or any figure as final or audited — every figure is a working number for review; never gives tax, legal, or audit opinions — those belong to the fund's CPA, counsel, and auditor.
Where it hands off: The waterfall the fee sits beside → THE WATERFALL CARD. The expense ratio it feeds → THE EXPENSE CARD.
It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source. The holder brings their own AI; no endorsement by Anthropic or any other AI company is claimed. Names of other companies and standards are used only to say what the card works with.

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 medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. Not investment advice, not an appraisal and not an offer to sell securities. The terms →
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.
AFTER YOU PAY · SIGN IN WITH THE EMAIL YOU PAID WITH · THE CARD OPENS ON MY CARDS → · CHECKED AGAINST ITS FINGERPRINT · NOTHING TO WAIT FOR
A TERM, NOT A SUBSCRIPTION: NOTHING RENEWS ITSELF AND NOBODY IS CHARGED AGAIN. WHEN A TERM ENDS THE FILES STAY ON YOUR COMPUTER AND STAY READABLE — FREEZE, NOT LOSS.

QUESTIONS AT THE TABLE
Asked before the wire.
What does it need from me?
Your own files and figures, on your own disk. It starts by asking for them: committed capital during the investment period, as the LPA states. If something it needs is missing, it marks it and says so — it never fills a gap with a guess.
Does it send anything anywhere?
No. The machine is a standard-library Python program that runs on your own computer and sends nothing anywhere; the words run wherever an AI reads Markdown. No server, no account, no key.
What is on the record?
The machine's selftest (7/7), run from inside the packet in Claude on 2026-10-20 on the studio's own example inputs and printed below as it ran; the twelve-check audit (AUDIT.md, 12/12); MANIFEST.md with every file hashed. RUN.md in the box is that run, dated. Still to come, as the next receipt: the card's test prompts asked in fresh chats with the card installed. The punch on the face is the SHA-256 of SKILL.md, so a downloaded copy can be checked against this room.
Can it be wrong?
Yes — it is an AI reading a text file: it can be wrong and can invent a number, a rule, a name or a date; check what matters against your own records and the source; the risk is yours. It models the fee from the terms you give it. The LPA governs the real fee, offsets, and waivers; the administrator calculates and the auditor checks it.
What will it never do?
It never hard-types a fee that should be computed — every year's fee derives from the basis and rate you give; never files a regulatory document or submits anything to a regulator, an LP, or an auditor on anyone's behalf; never certifies a NAV, a valuation, or any figure as final or audited — every figure is a working number for review; never gives tax, legal, or audit opinions — those belong to the fund's CPA, counsel, and auditor.
