SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When facing a complex decision or a problem you keep circling on, intuitive thinking often misses structural blind spots. This Skill turns any problem into a structured thinking exercise by explicitly applying the most relevant mental models to your specific situation, surfacing non-obvious insights without telling you what to decide. ## Core Features & Use Cases - Targeted Model Selection: Chooses 2-3 structurally relevant frameworks from a library of 20 mental models (First Principles, Inversion, Second-Order Thinking, Occam's Razor, and more) rather than applying generic advice. - Situation-Specific Application: Every model is worked through using your actual details, ending with a non-obvious insight and a short synthesis identifying the highest-leverage decision point. - Use Case: You are deciding whether to quit a stable job for a startup offer. The Skill applies Regret Minimization, Opportunity Cost, and Second-Order Thinking to your exact situation, revealing which downside is recoverable and which is not. ## Quick Start Describe your problem or decision in plain language, for example: "Help me think through whether I should raise a seed round now or keep bootstrapping."

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I use mental models to make a difficult decision?

Describe your decision or problem in plain language, including the options you are weighing. The Skill selects 2-3 relevant mental models, applies each to your specific details, and synthesizes the insights into a highest-leverage takeaway.

What mental models are included in this framework library?

The library contains 20 models including First Principles Thinking, Inversion, Second-Order Thinking, Occam's Razor, Sunk Cost Fallacy, Regret Minimization, Probabilistic Thinking, Pareto Principle, and Systems Thinking. Each entry includes when to apply it and a worked example.

Why does the Skill only apply 2-3 mental models per query?

Applying more than 3 models dilutes the analysis and produces generic output. Depth beats breadth: selecting the few models that are structurally relevant to your specific problem surfaces sharper, non-obvious insights.

Can mental models replace professional financial or legal advice?

No. The models sharpen your thinking about a decision but do not replace professional expertise. For legal, medical, or financial decisions, the Skill explicitly notes that professional advice is required before acting.

What happens if my problem description is too vague?

The Skill asks exactly one clarifying question to identify the core decision or tension before proceeding. It will not apply models until there is a substantive problem to work with.
