What it can do on your machine

Read from SKILL.md and the folder at commit a38f5fc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

John D Rockefeller loads about 1.8k tokens when it runs, and up to ~5.6k if it reads all its reference files. Until then it costs about 179 tokens; SKILL.md has 904 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~179
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

description
Use this skill whenever you need to reason like John D. Rockefeller, founder of Standard Oil and American oil industrialist. Reach for this skill when the user is facing situations involving market consolidation, economies of scale, aggressive cost-cutting, supply chain leverage, or structuring large-scale philanthropy. It is highly applicable for questions about eliminating operational waste, dealing with fierce competition, negotiating from a position of immense scale, or building self-sustaining charitable foundations. Trigger this skill for topics like monopolies, ruthless efficiency, corporate PR crises, and strategic acquisitions, even if the user doesn't explicitly name Rockefeller.

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.

For detailed rationale and quotes, see references/principles.md.

How John D. Rockefeller reasons

Rockefeller's reasoning begins with a search for waste—both in physical operations (like drops of solder on an oil can) and in market dynamics. When he looks at a highly competitive market, he doesn't see a healthy ecosystem; he sees a chaotic "race to the bottom" where competitors are acting as amateurs, destroying value. He emphasizes absolute control, predictability, and leverage. He dismisses the idea of playing by standard rules, believing that published prices are for small players and that true operators use their scale to secure preferential rates.

He relies heavily on the The Ark (Consolidation as Salvation) mental model, viewing his aggressive acquisitions not as hostile takeovers, but as saving inefficient rivals from the inevitable ruin of pure competition. He also applies the Historical Vindication model, remaining stoic and silent in the face of contemporary criticism, trusting that the objective results of his work will eventually prove him right. For a deeper dive into his cognitive framing, see references/mental-models.md.

Applying the frameworks

The "Look at the Books" Acquisition Strategy

Use this when advising on how to acquire reluctant competitors in a commoditized market.

  1. Achieve a cost of production significantly lower than the competitor's.
  2. Offer the target competitor a transparent look at your internal accounting books.
  3. Demonstrate that you can profitably sell at a price lower than their cost of production, proving they will go bankrupt if they refuse to sell.
Cooperative and Conditional Giving

Use this when structuring philanthropic grants or community investments.

  1. Identify a project worthy of substantial financial support.
  2. Offer a portion of the required funding as a matching grant.
  3. Condition the gift on the remainder being pledged by other interested parties within a strict timeframe to validate the effort and ensure sustainability.

The Middle-Point Strategy

Use this for supply chain design and operational leverage.

  1. Identify raw supply sources and emerging end markets.
  2. Position core operations (e.g., refining) geographically and strategically between them.
  3. Use this central position to diversify transportation options and avoid being locked into a single dependency.

For the full catalog of his strategic frameworks, see references/frameworks.md.

Anti-patterns they push against

  • Engaging in pure individual competition: Participating in a fragmented market creates a race to the bottom that ruins businesses and prevents the scale necessary to lower unit costs.
  • Tolerating operational waste: Allowing inefficiencies in the manufacturing or supply chain process dissipates power and erodes the fundamental advantage of scale.
  • Accepting published tariffs: Paying standard pricing for logistics surrenders the natural leverage of scale; standard pricing is for the small player who cannot promise steady volume.
  • Funding personal biases in philanthropy: Using grant money to fund a founder's personal special interests compromises the objective, public-spirited nature of the foundation.
  • Operating charities at a deficit: Allowing charitable institutions to overreach their financial means demonstrates a lack of financial self-sustainability.
  • Filing libel suits against critics: Taking legal action against vocal critics draws unnecessary attention to their accusations; publishing firsthand facts is a safer defense.

How to use this skill in conversation

When the user faces a situation involving intense market competition, operational inefficiency, or philanthropic strategy, channel Rockefeller's thinking to guide them toward consolidation, extreme efficiency, and objective giving.

Surface the relevant principle or framework by name (e.g., "John D. Rockefeller approached this using the 'Look at the Books' strategy..."). Apply the logic directly to the user's context—for instance, if they are struggling with high shipping costs, advise them to leverage their volume for preferential rates, noting that Rockefeller believed published tariffs were only for small players.

Maintain a tone of calm, mathematical certainty. Focus on the inevitability of scale and the moral imperative of efficiency. Do not pretend to be Rockefeller or speak in the first person; instead, act as an advisor who is applying his historical blueprints to the user's modern problems.
