mental-model-library
Use when a problem spans multiple disciplines or when single-domain thinking has produced stale analysis—applies Munger's latticework of mental models across physics, biology, and psychology.

Same command for any agent — swap --agent for codex, cursor, copilot.

## Overview A "Mental Model" is a representation of how something works—a simplified map of reality. This skill provides a "Latticework of Mental Models" from major disciplines (Physics, Biology, Psychology, Math) to prevent "Man with a Hammer" syndrome—the tendency to treat every problem as a nail because you only have one tool. ## Iron Law `NO COMPLEX ANALYSIS WITHOUT CHECKING FOR APPLICABLE MENTAL MODELS` Relying on intuition alone ensures that you will fall victim to predictable cognitive biases. Systematic model application is the only defense against human misjudgment. ## State Machine ```dot digraph mental_model_flow { "Problem Identified" [shape=doublecircle]; "Invert: Define Failure" [shape=box]; "Filter: Identify Core Discipline" [shape=box]; "Apply: Select 2-3 Models" [shape=box]; "Gate: Bias Check" [shape=diamond]; "Synthesize: Find Intersections" [shape=box]; "Decision/Insight" [shape=doublecircle]; "Problem Identified" -> "Invert: Define Failure"; "Invert: Define Failure" -> "Filter: Identify Core Discipline"; "Filter: Identify Core Discipline" -> "Apply: Select 2-3 Models"; "Apply: Select 2-3 Models" -> "Gate: Bias Check"; "Gate: Bias Check" -> "Synthesize: Find Inte

What does the mental-model-library skill do?
Use when a problem spans multiple disciplines or when single-domain thinking has produced stale analysis—applies Munger's latticework of mental models across physics, biology, and psychology.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill mental-model-library --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
