What it does

The skill instructs the agent to fully adopt Warren Buffett's cognitive framework, language, posture, and perspective when invoked, adopting his patience, value frameworks, aversion to unnecessary complexity, dry Omaha humor, and obsession with reading. It presents structured content about Buffett’s biography, timeline, investment philosophy, moat framework, management evaluation, cash flows, emotional temperament, and Berkshire Hathaway structure. It emphasizes specific decision criteria such as circle of competence, moat evaluation, management quality, predictable cash flows, and long holding periods. It also discusses famous letters and attitudes toward tech investments, including the Apple, Coca-Cola, American Express, and other holdings.

The content is organized into sections covering who Buffett is, strategic timeline, the eight-dimensional analysis model, emotional discipline, Mr. Market framework, personality traits, Berkshire’s vehicle, and Apple/tech views, including historical cautions and strategic pivots.

Key explicit instructions include the activation procedure describing adopting Buffett's mindset and the emphasis on reading and disciplined capital allocation. It also provides concrete examples of Buffett’s behavior in various market conditions and concrete criteria for evaluating investments.

How it works

Upon invocation, the agent assumes Buffett’s cognitive structure and manner, using his long-term, disciplined value investing approach. It outlines the persona through a sequence of sections:

    1. Who Buffett is and his strategic evolution across periods (Cigar Butt, Moats, Modern Capital Allocation).
    1. Foundational schools (Graham value investing and Munger qualitative refinement) and synthesis.
    1. The eight-dimension analysis model (Circle of Competence, Moat, Management, Predictable Cash Flows, Emotional Temperament, Mr. Market framework, verified personality traits).
    1. Berkshire Hathaway as the optimal vehicle (float from insurance, subsidiaries, and equity holdings).
    1. Berkshire Letters as educational material and recurring themes.
    1. Tech skepticism and the Apple investment rationale.

The agent provides explicit factual content and quotes related to Buffett’s philosophy and actions, framed as instructional material rather than predictive outcomes.

When to use it

  • When you need specialized assistance with this domain
  • Do not use when the task is unrelated to Warren Buffett, a simpler tool suffices, or the user requires general-purpose non-domain-specific help.

What it can touch

  • Tools listed in the skill: claude-code, antigravity, cursor, gemini-cli, codex-cli. (These appear under tools in the skill description.)

Caveats

  • risk: safe
  • License: MIT
  • Source: community
  • Author: renat
  • The content reflects Buffett’s perspectives and historical narrative; it does not guarantee investment outcomes and should be interpreted as guidance based on Buffett’s public thinking and documented actions.

About this skill
What does the warren-buffett skill do?

Agente que simula Warren Buffett — o maior investidor do seculo XX e XXI, CEO da Berkshire Hathaway, discipulo de Benjamin Graham e socio intelectual de Charlie Munger.

How do I install it?

Run `npx skills add sickn33/agentic-awesome-skills --skill warren-buffett --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
