buffett
by agi-nowbuffett is a Warren Buffett-style investment analysis skill for Finance. Use the buffett skill to evaluate stocks, read annual reports, test moats, assess management, estimate intrinsic value, and make buy/hold/sell decisions with a clear buffett guide.
This skill scores 78/100, which means it is a solid listing candidate for users doing Buffett-style investment analysis. The repository gives directory users enough workflow substance to justify installation, with clear trigger language and substantial reference coverage, though it still lacks some adoption conveniences that would reduce setup guesswork.
- Strong triggerability: the description explicitly says it should activate for stock analysis, annual reports, moats, management quality, valuation, and buy/hold/sell decisions.
- Good operational depth: the body points users to 8 reference files covering frameworks, philosophy, moats, management, metrics, valuation, risk, and industry playbooks.
- Low placeholder risk: valid frontmatter, no placeholder markers, and a sizeable body with headings and code fences suggest real workflow content rather than a stub.
- No install command or setup guidance in SKILL.md, so users may need to infer adoption steps.
- The description is broad and expansive, which helps triggerability but may also encourage over-triggering on general finance topics.
Overview of buffett skill
What the buffett skill is for
The buffett skill is an investment-analysis workflow built around Warren Buffett-style thinking: business quality, moat durability, management integrity, intrinsic value, and capital allocation. Use the buffett skill when you need to evaluate a stock, read an annual report, compare buy/hold/sell cases, or decide whether a business belongs in your circle of competence.
Who should install buffett
Install buffett if your work regularly touches Finance, public equities, or company quality review. It fits analysts, founders, investors, and agents that need a structured buffett guide for judgment-heavy decisions, not just a generic “summarize this company” prompt.
What makes buffett different
The main advantage of buffett for Finance is its decision framework: it pushes toward durable economics, honest management, and owner-earnings thinking instead of headline multiples alone. It is most useful when the answer depends on whether a business can compound capital well over time.
How to Use buffett skill
Install and trigger buffett
Use the repo’s install flow for the buffett install step, then invoke the skill whenever the task is about an investment decision or business-quality assessment. If you are composing a prompt, make the ask explicit: “Analyze this company using buffett,” “Apply the buffett skill to this 10-K,” or “Use buffett for Finance to assess moat, management, and intrinsic value.”
Give inputs that help the skill work
The skill works best when you provide:
- the company name and ticker
- the decision you want: buy, hold, sell, compare, or investigate
- the time horizon
- the relevant documents: annual report, shareholder letter, earnings call, or financial statements
- any constraints, such as avoiding complex modeling or focusing on downside risk
A weak prompt says, “Is this stock good?” A stronger one says, “Using buffett, evaluate whether Company X has a durable moat, honest management, and a reasonable price based on the last 3 years of filings.”
Read the right files first
Start with SKILL.md, then inspect the references/ files that match the task. The most useful entry points are:
references/01-thinking-frameworks.mdreferences/03-business-moat.mdreferences/04-management-governance.mdreferences/05-financial-metrics.mdreferences/06-valuation-capital.md
If the question is about risk or exit decisions, read references/07-risk-behavior.md early. If it is industry-specific, use references/08-industry-playbooks.md before drafting conclusions.
Workflow that improves output quality
A practical buffett usage flow is: define the decision, identify the business model, test the moat, verify management quality, normalize earnings, and only then discuss valuation. This order matters because a cheap price does not fix a weak business, and a strong business can still be a bad purchase if the margin of safety is thin.
buffett skill FAQ
Is buffett only for stock picks?
No. The buffett skill also fits annual-report reading, moat analysis, capital allocation review, and “should I sell?” questions. It is broader than stock picking but narrower than general business advice.
Do I need to mention Buffett to trigger it?
Not always. The skill is meant to activate on investment-analysis problems even if the user does not say “Buffett.” For best results, still name the buffett skill when you want that specific framework applied.
Is buffett beginner-friendly?
Yes, if the user can provide a company and a decision. Beginners get the most value when they ask for a structured readout instead of a verdict-only answer. The skill is less useful if the user wants a quick news summary with no finance context.
When should I not use buffett?
Skip buffett for short-term trading, technical charting, or purely macro forecasting. It is not optimized for momentum calls, options tactics, or themes that do not depend on business economics.
How to Improve buffett skill
Give the skill better evidence
The fastest way to improve buffett results is to supply primary-source material: filings, shareholder letters, segment data, and management commentary. For buffett for Finance, the more the prompt includes real operating numbers and capital allocation facts, the less the answer will rely on guesswork.
Ask for the decision, not just analysis
The skill performs better when the prompt forces a recommendation path. Good examples:
- “Is the moat widening or shrinking?”
- “Would Buffett likely buy, hold, or avoid this business?”
- “What would need to be true for this to be a margin-of-safety purchase?”
This keeps the output anchored to an investment choice instead of a generic company description.
Fix the common failure modes
The most common weak inputs are vague industries, no time horizon, and no documents. Another failure mode is asking for valuation before business quality is clear. If the first pass feels shallow, tighten the prompt around one question: moat, management, earnings power, or price.
Iterate with sharper follow-ups
Use the first answer to refine the next prompt. For example, ask the skill to:
- separate temporary issues from permanent moat damage
- estimate owner earnings from the last few years
- explain the main risk that could invalidate the thesis
- compare the business to a stronger peer
That kind of iteration turns the buffett guide from a broad framework into a better investment memo.
