Munger Models Graph Skill

A Codex Skill for applying the MungerModels.com Charlie Munger mental-model knowledge graph to decisions, investments, business analysis, risk reviews, organization design, and learning plans.

This is a graph-based analysis skill, not a pure roleplay prompt. It helps Codex select and combine relevant mental models across disciplines, then turn them into diagnostic questions, failure modes, and practical checklists.

What It Contains

• SKILL.md - skill trigger metadata and operating workflow.
• references/graph-analysis.md - parsed graph structure, central models, scenario playbooks, and source URL patterns.
• agents/openai.yaml - UI metadata for Codex skill discovery.

Core Coverage

The skill is based on the public Munger Models knowledge graph:

• 232 mental models
• 14 disciplines
• 9 application scenarios
• 1,757 graph edges on the graph page

It highlights central models such as 安全边际, 护城河, 逆向思维, 能力圈, 社会认同倾向, Lollapalooza倾向, 复利效应, and 概率思维与期望值.
