What this skill does

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 Example Scheduling (Optional) Set up a cron job for daily automated review: Recommended time: End of workday (e.g., 5pm local) Trigger message: MUNGEROBSERVERRUN
