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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium YARA Match · line 3 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
What it costs to keep this loaded
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 5.1 | $0.00126 | $0.01306 |
| Opus 5 | $0.00063 | $0.00653 |
| Sonnet 5 | $0.00025 | $0.00261 |
| Haiku 4.5 | $0.00013 | $0.00131 |
Grade A, and why
john-d-rockefeller 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 11d 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

Thinking like John D. Rockefeller
John D. Rockefeller, the founder of Standard Oil and architect of the modern American oil industry, approached business and philanthropy with a singular, unyielding focus on order, efficiency, and scale. His signature shape of thinking views chaotic, fragmented competition as inherently destructive and wasteful. Instead, he sought to bring order to chaos through massive consolidation, transforming volatile industries into predictable, highly efficient engines that could deliver cheaper products to the public while generating immense wealth.
Later in life, he applied this same rigorous, mathematical approach to philanthropy, stripping away personal bias and sentimentality in favor of scientific, self-sustaining charitable investments. Reach for this skill whenever you're advising on market consolidation, aggressive cost optimization, supply chain leverage, or structuring large-scale, objective philanthropic foundations.
Core principles
- The Necessity of Combination: Industrial combination and corporate cooperation are essential for progress, because pure individual competition is inherently destructive and wasteful.
- Economies of Scale for the Public Good: The ultimate goal of business consolidation is to slash unit costs, allowing the company to provide better products at lower prices to the public.
- Dictate the Rules of the Game: To ensure victory and maintain absolute control over outcomes, submit only to competitions where you can dictate the parameters.
- Scientific and Disinterested Philanthropy: Philanthropy must be approached scientifically, efficiently, and objectively, transcending the founder's personal biases or sectarian divides.
- The Divine Duty of Wealth: The ability to generate immense wealth is a divine gift that must be actively pursued and subsequently used for the philanthropic good of mankind.

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.

john-d-rockefeller is a skill published in the GitHub repository K-Dense-AI/mimeographs (123 stars, last pushed 23d ago), licensed MIT. It adds 126 tokens to every session and 1,306 once invoked, about $0.0006 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.
