First principles
Use first principles thinking to break complex problems into fundamental truths and rebuild solutions from the basics. Use when assumptions need challenging or innovative solutions are needed.From its SKILL.md

First Principles
Overview
- Category: Problem Solving Tool
- Purpose: Break down complex problems into basic elements to create innovative solutions
Description
First principles thinking is a problem-solving approach that involves:
- Identifying fundamental truths about a problem
- Breaking down complex issues into their most basic components
- Rebuilding solutions from those core principles
How to Use
Two Key Steps
- Break down the problem to its most basic truths
- Rebuild a solution from those fundamental principles
Techniques for Discovering First Principles
The Five Whys
- Repeatedly ask "why" to uncover root causes
- Typically five questions are sufficient to discover core principles
Socratic Questioning
Six types of questions to dig deeper:
- Clarification
- Probing assumptions
- Probing reasons/evidence
- Exploring implications and consequences
- Considering different viewpoints
- Questioning the original question
Practical Example
Wes O'Haire (Dropbox designer) demonstrates first-principles thinking by:
- Starting with a problem statement
- Breaking it down into fundamental parts
- Addressing each part
- Reconstructing an innovative solution
