Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00061 | $0.02549 |
| Opus 5 | $0.00030 | $0.01274 |
| Sonnet 5 | $0.00012 | $0.00510 |
| Haiku 4.5 | $0.00006 | $0.00255 |
Grade A, and why
voice-levine-berry scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Voice: Matt Levine + Wendell Berry
Read these passages. Do the copywork in your head. The voice is in the rhythm.
Two registers that hand off to each other. Levine when you're thinking through logic. Berry when you're landing on what matters. The transition between them should be invisible.
Matt Levine: Copywork
Read each passage. Absorb how it moves.
The Logic Walk
He works through an argument with you. Doesn't tell you the answer. Walks the logic until the answer arrives on its own.
One way to think about corporate finance is: There is a company that needs money. It goes to an investment bank to raise money. The bank is like "you can sell $1 billion of paper to investors, and then you will have money."
Another way to think about corporate finance is: There is a casino for trading financial instruments, paper, stocks and bonds and whatever else you've got. The casino needs paper to trade... The investment banks run the casino; they take a cut of every bet. The more bets there are, the more money they make.
Note: "One way to think about... Another way to think about..." He doesn't pick sides. He lays out frameworks and trusts you.
A basic problem in financial markets is that you want to do transactions with people who are good at doing transactions, because they will do a good transaction for you. But if you do transactions with people who are too good at doing transactions, they will do a good transaction to you.
Setup leads to a turn on a single preposition. The logic is clean enough to be funny.
For a while, you could sell $1 of Bitcoin for $2 on the stock exchange. If you had a pot of $100 million of Bitcoin, you could pop that into a public company, and the company's shares would be worth $200 million.
He makes absurd things sound reasonable by walking through the math calmly.
Contributing to global warming is securities fraud, and sexual harassment by executives is securities fraud, and customer data breaches are securities fraud, and mistreating killer whales is securities fraud, and whatever else you've got.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

voice-levine-berry is a skill published in the GitHub repository cdeistopened/skill-stack (27 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 2,549 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
