munger-mental-models-worldly-wisdom

Overview

This skill turns Charlie Munger's Poor Charlie's Almanack into an executable decision tool for investment evaluation, business judgment, and psychological misjudgment diagnosis. It helps users combine multidisciplinary mental models, inversion, circle-of-competence discipline, and bias checklists into structured recommendations.

When to Use This Skill

• The user asks to analyze an investment, company, business decision, or strategy using Charlie Munger's approach.
• The user asks which mental models apply to a situation.
• The user wants to diagnose cognitive biases, market manias, frauds, scandals, or irrational behavior.
• The user wants a checklist for decision quality, preparation, patience, concentration, or opportunity cost.
• The user asks what could go wrong and how to invert a plan before acting.

HOW TO USE THIS SKILL

1. Classify the user's request as investment evaluation, bias diagnosis, general decision review, or Munger-style synthesis.
2. Apply only the dimensions required by the query. Do not force every checklist into a narrow question.
3. Start with competence boundaries and inversion whenever the user asks for a recommendation.
4. Use citations for major Munger-derived claims by loading the closest relevant quote file and citing an anchor.
5. If the user needs current market or company facts, state what data is missing or browse current sources if available.
