What problem does it solve? Investors often buy stocks on impulse, tips, or FOMO without a disciplined framework. This Skill enforces a systematic Buffett-style value investing checklist before any purchase, covering business understanding, economic quality, moat, management, valuation margin of safety, and decision discipline, so bad choices get filtered out before capital is committed. ## Core Features & Use Cases - Six-Gate Checklist: Scores each company (1-5 stars) across circle of competence, business economics, moat depth, management trustworthiness, margin of safety, and position discipline, with hard veto rules. - Multi-Company Parallel Analysis: Accepts multiple tickers or company names at once, launches parallel data collection, and produces a side-by-side comparison table. - Deterministic Financial Verification: Calls a bundled Python toolkit for exact-decimal valuation checks (PE, PB, ROE, FCF yield), three-scenario valuation modeling, cross-source data validation, and Benford's Law fabrication screening. - Use Case: Ask it to run the checklist on Tencent, Moutai, and NVIDIA; it produces per-company scorecards, a mirror-test statement, a quick-veto scan, and a final pass/fail/gray-zone verdict written to a Markdown report. ## Quick Start Ask the agent to run the Buffett pre-buy checklist on the companies you are considering, for example: run the investment checklist on Tencent, Moutai, and NVDA.
