Details
From the project READMEMental 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
When activated (Trigger phrases: "Evaluate this model", "Run the mental models", "Stress test this idea"):
- Read the user's proposed plan or idea.
- Output a structured markdown report that addresses the plan through the lens of at least 3 of the mental models above.
- Conclude with a final
PASS,REVISE, orREJECTverdict.
