SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Unstructured thinking leads to missed risks, biased decisions, and shallow analysis. This Skill guides you through proven thinking frameworks so you can decompose problems, evaluate decisions, and plan strategically with a repeatable process. ## Core Features & Use Cases - 59 Models Across 12 Categories: Covers cognitive, diagnostic, strategic, analytical, creative, operational, validation, communication, learning, and risk frameworks. - Guided Model Selection: A scanner script lists available models, then the assistant offers 2-3 relevant options based on your situation before loading the chosen model file. - Question-Driven Application: Each model file provides purpose, when-to-use guidance, ready-to-ask questions, and a step-by-step process. - Use Case: Before launching a project, run a Pre-Mortem to surface failure risks, then apply First Principles to challenge core assumptions about the plan. ## Quick Start Ask the assistant to help you think through a decision using a mental model such as a pre-mortem or first principles analysis.

Frequently Asked Questions about mental-models

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

FAQPage Schema
How do I choose the right mental model for a decision?

Run the selection script to list all 59 models, then describe your situation. The assistant offers 2-3 relevant options such as Decision Matrix, Pre-Mortem, or Cost-Benefit analysis, and loads the model file you pick.

What mental models help with root cause analysis?

The diagnostic category includes 5 Whys, Fishbone diagrams, Pre-Mortem, Force Field analysis, and Fault Tree analysis. Each model file provides question prompts and a step-by-step process for investigating causes.

Can I combine multiple thinking frameworks in one session?

Yes, combining models is supported and encouraged when appropriate. For example, you can apply First Principles to challenge assumptions and then run a Pre-Mortem on the resulting plan in the same conversation.

What frameworks are available for strategic planning?

The strategic category includes Scenario Planning, OODA Loop, Jobs to Be Done, Blue Ocean, PESTLE, and Porter's Five Forces. Operational planning adds OKR, Lean Canvas, and Theory of Constraints.

When should I not use a structured thinking framework?

Frameworks add overhead, so skip them for trivial or time-critical decisions where intuition suffices. They work best for consequential, ambiguous, or reversible-with-difficulty choices where structured analysis changes the outcome.
