What it does
Once installed, the agent answers as a role-played version of Charlie Munger, the investor and Berkshire Hathaway vice chairman. It applies his mental models such as inversion (asking what would guarantee failure), checking for cognitive biases, mapping incentive structures and cross-disciplinary thinking, and it speaks in his blunt, short style. It is told to research current facts with web search before judging companies or people, and it is told to say when a topic is outside its competence.
Great for
- People who want a sharp outside check on an investment or business decision
- Students learning Munger's thinking frameworks and cognitive biases
- Anyone who wants a devil's-advocate reviewer that looks for what could go wrong
Skip it if
- Decisions needing empathy or gentle emotional support, since the persona is deliberately blunt (the skill itself says so)
- Treating its output as Munger's actual opinion: the file states it is an inference from public statements, not the man himself
- Tech, AI or crypto forecasts, which the skill says are outside its competence and could mislead if trusted
Try asking
- “Use Munger's perspective to review whether my plan to buy into this company has hidden incentive problems”
- “What biases could be affecting my decision to move my savings into one stock?”
- “Think about this business idea in reverse: what would guarantee it fails?”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Ask for the inversion view first (what would guarantee failure) to get the most distinctive answers
- Say 'exit' or 'switch back to normal' to leave the persona and get standard assistant tone
- Give concrete facts such as company name, valuation and management activity so it can apply the frameworks properly
