dbt (data build tool) patterns for model organization, incremental strategies, and testing.
Think beyond immediate consequences to understand the chain reactions of decisions. Master Howard Marks' investment framework for seeing what others miss. Use when: **Strategic decisions** where long-term consequences matter; **Policy/rule changes** that will trigger behavioral responses; **Competitive moves** to anticipate market reactions; **Product decisions** where user behavior may shift; **Investment analysis** to see past obvious conclusions
Analyze card sorting results to inform information architecture and navigation structure. Use after conducting open or closed card sort studies.
A deterministic thinking partner that challenges assumptions and applies mental models to sharpen decisions, solve problems, and think more clearly. Use this skill whenever a user says "help me think through X", "challenge my thinking", "what am I missing", "apply mental models to this", "play devil's advocate", "stress test this idea", "poke holes in my plan", "help me decide between X and Y", "what are the second-order effects", "I'm stuck on a decision", names any specific model (SWOT, first principles, inversion, pre-mortem, etc.), or asks for structured reasoning on any ambiguous, high-stakes, or complex problem. Also trigger when the user seems uncertain, is rationalizing, or is asking "am I thinking about this right?" Even casual phrases like "what do you think about..." on non-trivial topics should trigger this skill.
Channel the mental models, decision frameworks, and communication style of real experts (Steve Jobs, DHH, Rich Hickey, etc.) to approach problems the way they would. Use when the user says "summon", "channel", "what would [name] think", "ask [name]", or wants an expert perspective on a problem.
Meta-skill: research a thinker's framework deeply, then synthesize a new Claude Code skill that applies their thinking to business ideas. Takes a prompt like "/add-thinker Andy Grove — Only the Paranoid Survive" and produces a new skill at .claude/skills/<thinker>/SKILL.md that works like /munger does. Use when the user says "add thinker", "add a new thinker", "codify X's thinking", or "make a skill for <person>'s framework".
Apply 25 professional mental models to solve complex problems. Use when: (1) facing multi-faceted challenges that require diverse perspectives, (2) stuck in single-minded approaches, (3) need innovative solutions, (4) making major decisions with multiple stakeholders, (5) understanding complex human behavior, or (6) seeking to break cognitive biases and adopt alternative viewpoints.
"Invert, always invert." Apply Carl Jacobi's mathematical principle and Charlie Munger's investing wisdom to solve problems by thinking backward from failure. Use when: **Goal setting** - Define what would guarantee failure, then avoid it; **Risk analysis** - Identify what could destroy your project before starting; **Decision making** - Evaluate choices by examining their worst outcomes; **Problem solving** - When direct approaches aren't working, reverse the question; **Strategy development...
Multidisciplinary decision-making using mental models from psychology, economics, mathematics, and science to identify high-conviction opportunities and avoid cognitive biases. Keywords: latticework, lollapalooza, circle of competence, inversion, moats. NOT for single-discipline analysis, high-frequency trading, or speculative diversification.
Combine multiple mental models for richer analysis. Use for complex problems requiring multiple lenses, high-stakes decisions, or when single models leave blind spots.
Talk to Greg Isenberg about their expertise. Greg Isenberg provides authentic advice using their mental models, core beliefs, and real-world examples.
Apply behavioral science and mental models to improve marketing outcomes.
