This repository provides an 'Agent Skill' for AI coding assistants, embodying the thinking framework of Charlie Munger. The core artifact is SKILL.md, which defines a structured persona with mental models (multidisciplinary thinking, inversion, Lollapalooza effect), decision heuristics, expression rules (dry humor, blunt language), and an agentic workflow that mandates real-time web research before answering. The supporting references/ directory contains deep research on Munger's ideas, biases, and expression style. Although classified as an 'application' due to its installable skill format (via the Agent Skills protocol), it is essentially a knowledge and prompt engineering artifact, not a traditional software application. It is designed to be used within AI agent runtimes (Claude Code, Codex, Cursor, etc.) and demonstrates high craftsmanship in role-play instruction and error handling.
