# First Principles Thinking Skill A Claude Code skill that provides systematic first principles thinking methodology for evaluating designs, challenging assumptions, and building solutions from fundamental truths. ## What is This? This is a **skill** for [Claude Code](https://claude.ai/code) that enhances Claude's ability to analyze problems from first principles rather than relying on analogies or conventions. ## Installation ### Option 1: Copy to your skills directory ```bash # Clone the repo git clone https://github.com/tt-a1i/first-principles-skill.git # Copy to Claude Code skills directory cp -r first-principles-skill ~/.claude/plugins/superclaude/skills/first-principles ``` ### Option 2: Symlink ```bash git clone https://github.com/tt-a1i/first-principles-skill.git ~/skills/first-principles-skill ln -s ~/skills/first-principles-skill ~/.claude/plugins/superclaude/skills/first-principles ``` ## Usage The skill triggers automatically when you use phrases like: | Language | Trigger Phrases | |----------|-----------------| | English | "analyze from first principles", "think from scratch", "question this design", "is this the right approach", "challenge assumptions" | | Chinese | "第一性原理", "从根本分析", "从零开始思考", "这个设计合理吗", "为什么要这样做", "有没有更好的方案" | ### Example ``` User: 用第一性原理分析一下我们是否应该采用微服务架构 Claude: [Applies first principles thinking methodology] ## First Principles Analysis: Microservices Architecture ### 1. Problem Essence **Core problem:** Enable faster development and independent scaling **Success criteria:** Deploy without full regression, scale components independently ### 2. Assumptions Challenged | Assumption | Challenge | Verdict | |------------|-----------|---------| | Need microservices for modern apps | Do we have the team size? | Investigate | ... ``` ## Structure ``` first-principles-skill/ ├── SKILL.md # Main skill definition ├── README.md # This file ├── LICENSE # MIT License ├── references/ │ ├── software-examples.md # Software engineering case studies │ └── elon-musk-examples.md # SpaceX/Tesla examples └── examples/ └── architecture-review.md # Complete microservices analysis example ``` ## Core Methodology The skill follows a 5-phase process: 1. **Identify Problem Essence** - Strip away details to find the core problem 2. **Challenge Assumptions** - Question every assumption systematically 3. **Establish Ground Truths** - Identify irreducible facts 4. **Reason Upward** - Build solutions from fundamentals 5. **Validate Reasoning** - Ensure every decision traces to ground truths ## Output Format The skill produces structured analysis: ```markdown ## First Principles Analysis: [Topic] ### 1. Problem Essence ### 2. Assumptions Challenged (table) ### 3. Ground Truths ### 4. Reasoning Chain ### 5. Conclusion ``` ## Complementary Skills This skill works well with: - **5-Whys** - Dig deeper when assumptions surface - **Trade-off Analysis** - Evaluate options against fundamentals - **Pre-mortem** - Stress-test reasoning before implementation ## Contributing Contributions welcome! Please feel free to submit issues or pull requests. ## License MIT License - see [LICENSE](LICENSE) file. ## Author Created for use with Claude Code's skill system.
