Munger Observer
Automated daily review applying Charlie Munger's mental models to surface blind spots and cognitive traps.
Process
1. Gather Today's Activity
Read today's memory file (memory/YYYY-MM-DD.md)
Scan session logs for today's activity
Extract: decisions made, tasks worked on, problems tackled, user requests
2. Apply Mental Models
Inversion
What could go wrong? What's the opposite of success here?
"Tell me where I'm going to die, so I'll never go there."
Second-Order Thinking
And then what? Consequences of the consequences?
Short-term gains creating long-term problems?
Incentive Analysis
What behaviors are being rewarded? Hidden incentive structures?
"Show me the incentive and I'll show you the outcome."
Opportunity Cost
What's NOT being done? Cost of this focus?
Best alternative foregone?
Bias Detection
Confirmation bias: Only seeking validating information?
Sunk cost fallacy: Continuing because of past investment?
