Mental Model Evaluator

"Measure twice, cut once."

Before making major architectural decisions, writing a massive feature, or executing a high-stakes trade plan, this skill forces a pause and runs the proposed plan through established cognitive mental models.

Core Mental Models

Inversion: "How could this plan completely fail?" Works backwards to identify guaranteed failure states and ensures the plan mitigates them.
First Principles Thinking: Strips the plan down to fundamental truths. Are we building on an assumption, or an undeniable fact?
Second-Order Effects: "And then what?" Evaluates the downstream consequences of the decision beyond the immediate payoff.
Buffett's Moat Analysis: Does this feature/trade provide a sustainable, defensible advantage, or is it easily replicated noise?

Usage
