# 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? - Social proof: Doing it because others do? - Availability bias: Overweighting recent/vivid information? **Circle of Competence** - Operating within known territory or outside? - If outside, appropriate humility/caution? **Margin of Safety** - What's the buffer if things go wrong? - Cutting it too close anywhere? ### 3. Generate Output **If insights found:** 1-2 concise Munger-style observations **If nothing notable:** "All clear — no cognitive landmines detected today." ## Output Format ``` 🧠 **Munger Observer** — [Date] [Insight 1: Model applied + observation + implication] [Insight 2 if applicable] — "Invert, always invert." — Carl Jacobi (Munger's favorite) ``` ## Example ``` 🧠 **Munger Observer** — January 19, 2026 **Opportunity Cost Alert:** Heavy focus on infrastructure today. The content queue is aging — are drafts decaying in value while we polish tools? **Second-Order Check:** Speed improvement is good first-order thinking. Second-order: faster responses may raise expectations for response quality. Speed without substance is a trap. — "Invert, always invert." ``` ## Scheduling (Optional) Set up a cron job for daily automated review: - Recommended time: End of workday (e.g., 5pm local) - Trigger message: `MUNGER_OBSERVER_RUN` ## Privacy Addendum - Analyze only the minimum required memory/session span for the requested review. - Exclude credentials, financial account numbers, health data, and private identifiers from outputs. - Do not copy or forward personal excerpts outside the current workspace/session without explicit user instruction.
