Buffett

This implements Warren Buffett's investment analysis framework as a systematic checklist. It starts with an 8-question filter to quickly screen opportunities, then routes you through reference files based on what you're analyzing: business moats, management quality, financial metrics, valuation, industry-specific playbooks. The structure is opinionated. Management integrity is an automatic veto. It won't let you skip the circle of competence check. The output format is rigid by design, forcing you to address every section from assumptions to sell criteria. Best for anyone who wants to formalize value investing discipline rather than wing it, though you'll need to actually read and think through each section instead of just running a prompt.
