SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Investors often get vague, non-committal stock analysis from AI that cannot support real buy decisions. This Skill enforces a disciplined Buffett-style pre-purchase checklist that produces clear pass/fail verdicts, star ratings, and price-based conclusions for one or multiple companies. ## Core Features & Use Cases - Six-Gate Evaluation: Scores each company on circle of competence, business quality, moat, management, margin of safety, and position discipline using 1-5 star ratings. - Anti-Bias Mechanisms: Applies information richness grading (A/B/C), a quick-veto red-flag list, and a mandatory mirror test that rejects any thesis not explainable in five sentences. - Multi-Company Comparison: Analyzes several tickers in parallel and outputs a consolidated comparison table with per-gate scores and final conclusions. - Use Case: Ask to run the checklist on "Tencent, Moutai, NVIDIA" and receive per-company scored reports plus a side-by-side overview table with explicit pass/fail/gray-zone verdicts. ## Quick Start Run the Buffett investment checklist on Tencent and Pinduoduo and give me the scored comparison table with final buy verdicts.

FAQPage Schema
How do I run a Buffett-style checklist on a stock before buying?

Provide one or more company names or tickers, and the Skill walks each through six gates: circle of competence, business quality, moat, management, margin of safety, and position discipline. Each gate receives a 1-5 star score and the report ends with an explicit pass, fail, or gray-zone verdict.

Can I compare multiple stocks in one value investing analysis?

Yes, the Skill accepts multiple companies separated by commas or spaces and collects data for each in parallel. It then produces a consolidated comparison table showing per-gate star ratings and core conclusions across all companies.

What happens when a company has very little public data?

The Skill grades information richness as A, B, or C before analysis. For C-grade companies it avoids forcing conclusions, labels estimated figures with confidence levels, and marks the result as a gray zone requiring primary-source research rather than a fabricated verdict.

Does the checklist work for unlisted or private companies?

Unlisted companies are flagged as not listed with a brief note on possible indirect investment routes, and the full six-gate checklist is skipped. The final report marks them as N/A instead of producing a buy verdict.

What are the limitations of an AI-driven investment checklist?

The checklist depends on the accuracy and recency of collected financial data, so it mandates tool-based arithmetic instead of mental math and requires stating the data cutoff date. It is a screening framework to reject bad choices, not a guarantee of investment returns.
