    description: Daily wisdom review applying Charlie Munger's mental models to your work and thinking. Use when asked to review decisions, analyze thinking patterns, detect biases, apply mental models, do a "Munger review", or run the Munger Observer. Triggers on scheduled daily reviews or manual requests like "run munger observer", "review my thinking", "check for blind spots", or "apply mental models".

    # 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`
