john-d-rockefellerA skill your agent uses whenever you need to reason like John D.
John D Rockefeller is an agent skill from K-Dense-AI/mimeographs. 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…
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 74 other files, including reference files (for example `AGENTS.md`, `_workspace/agents_output.e584bd6c.json` and `_workspace/clustered_corpus.e584bd6c.json`).
It sits in Security, covering Supply chain security. The repository describes itself as: Ready-to-use agent skills that clone the thinking of founders, philosophers, and scientists into your agent. Generated with K-Dense-AI/mimeo. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit a38f5fc. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
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.
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.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/john-d-rockefeller/SKILL.md (or your agent's skills folder). This skill also uses 71 other files; get the full folder from GitHub.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.
For detailed rationale and quotes, see references/principles.md.
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.
Use this when advising on how to acquire reluctant competitors in a commoditized market.
Use this when structuring philanthropic grants or community investments.
Use this for supply chain design and operational leverage.
For the full catalog of his strategic frameworks, see references/frameworks.md.
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.
