Purpose
This skill provides Claude with 98 cognitive frameworks and mental models to improve problem-solving and decision-making. It acts as a thinking partner for analyzing decisions across disciplines like economics, science, and strategy.

Security Assessment
The overall risk is Low. The light code scan evaluated 7 files and found no dangerous patterns or hardcoded secrets. The tool does not request any dangerous system permissions, does not execute shell commands, and appears to make no network requests. It functions entirely locally by loading static text files (the mental models) into your Claude Code environment.

Quality Assessment
The project is actively maintained, with its most recent push happening today. It uses the standard, permissive MIT license. However, community visibility and trust are currently very low. The repository only has 6 GitHub stars, meaning the tool has not been widely peer-reviewed or battle-tested by a large user base.

Verdict
Safe to use, but keep in mind that community validation is currently minimal.

Mental models & cognitive frameworks as Claude Code skills for better decision-making

Mental Models for Claude Code

Claude Code Compatible
PRs Welcome

Turn Claude Code into a thinking partner with 98 Munger-style mental models bundled as a single skill.

A latticework for better decisions, one prompt away.

What It Does

Loads 98 cognitive frameworks into Claude Code as an auto-activating skill. Ask Claude to "apply inversion," "find the bottleneck," or "help me think through X" and it selects the right models, walks their Thinking Steps, and returns actionable insight.

Why Munger?

Charlie Munger argued that worldly wisdom comes from building a latticework of mental models drawn from many disciplines—then hanging experience on that lattice. A single discipline gives you a hammer; a latticework gives you judgment. This skill operationalizes that idea: instead of one framework, Claude reaches across psychology, physics, economics, math, and strategy to analyze your problem. Read more in Poor Charlie's Almanack or Farnam Street's Mental Models hub.

Quick Start

Install with copy:

git clone https://github.com/cyperx84/claude-skills-mental-models.git
cp -r claude-skills-mental-models/.claude/skills/mental-models ~/.claude/skills/

Or symlink (stays in sync with updates):

ln -s "$(pwd)/claude-skills-mental-models/.claude/skills/mental-models" ~/.claude/skills/mental-models

Then in Claude Code:

Apply inversion to my pricing strategy.

The skill auto-activates on phrases like help me think, apply mental model, or any model name (inversion, bottlenecks, second-order thinking, margin of safety...).

Usage Examples

Apply inversion to this architecture decision
