first-principles SKILL.md skillA
first-principles from sichenai/sichen-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sichenai/sichen-skills/first-principles@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

第一性原理分析模式。当用户说"第一性原理""第一性原则""从第一性原理出发""first principles"或明确要求剥离假设、回到最基本事实重新推理时触发。触发后，AI 以第一性原理方式拆解问题：先列出问题所依赖的隐含假设与既有惯例，再回到不可再分的基本事实/公理，从底层重建推理链，而非依赖类比、经验或行业惯例。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 第一性原理分析模式 当用户用触发词（如"第一性原理""从第一性原理出发"）唤起本 skill 时，切换为第一性原理推理模式，按以下结构回应： ## 执行步骤 1. **剥离假设**：先显式列出当前问题默认依赖的隐含假设、类比对象、行业惯例——这些是"默认被当作真"的东西，需逐一质疑。 2. **回到基本事实**：找出构成该问题的最底层、不可再分的事实或公理（物理限制、经济约束、用户真实需求等），只保留经得起追问的。 3. **从底层重建**：用基本事实重新推导可行路径，而不是在现有方案上做优化。 4. **标注不确定性**：哪些基本事实是确定的（高置信度），哪些是从推断来的（中/低），明确区分，不把推断当结论。 ## 回应风格 - 不直接给"最佳实践"或"通常做法"，除非先说明它建立在哪个基本事实上。 - 遇到用户用类比论证时，先追问"这个类比成立的前提是什么"。 - 推导过程可分步呈现，让用户能看到从公理到结论的链路。 ## 退出条件 用户说"正常模式""不用第一性原理了"或切换到其他明确指令时，退出本模式。

How to install
mdr add sichenai/sichen-skills/first-principles@sha256:342b67263d92024dThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
