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.
