ljg-think

lijigang/ljg-skills

Vertical deep-drilling thinking tool that traces ideas to their irreducible essence.

What is ljg-think?

A structured reasoning skill that takes a statement, observation, or question and systematically drills downward through layers of explanation until reaching fundamental truths. Use when you need depth analysis rather than breadth, or when exploring 'why' something is the way it is at its core.

  • Traces ideas vertically through multiple explanatory layers (social → psychological → biological → physical → logical)
  • Identifies the fundamental irreducible elements beneath surface phenomena
  • Generates a layered analysis showing each level of deeper understanding
  • Detects contradictions and gaps that signal transitions to deeper explanatory frameworks
  • Produces output in org-mode format with timestamped documentation

How to use ljg-think

  1. 1.Provide a statement, observation, phenomenon, or question you want to understand deeply
  2. 2.Trigger the skill by using keywords like '想透' (think it through), '追本' (trace to root), '本质是什么' (what is the essence), '深挖' (dig deep), or 'think deep'
  3. 3.The skill will systematically drill downward through explanatory layers, switching frameworks as needed
  4. 4.Review the generated org-mode file saved to ~/Documents/notes/ with the analysis

Use cases

Good for
  • Understanding why a social trend or behavior pattern exists at its root cause
  • Analyzing a philosophical or conceptual claim to find its logical foundations
  • Investigating a business or product problem to discover underlying systemic issues
  • Exploring psychological phenomena to trace them back to human nature or biology
  • Deconstructing a belief or assumption to expose its foundational premises
Who it's for
  • Researchers and analysts seeking root-cause understanding
  • Philosophers and critical thinkers exploring fundamental questions
  • Product and business strategists diagnosing systemic problems
  • Anyone wanting to move beyond surface-level explanations

ljg-think FAQ

How many layers will the analysis go?

Layer count varies by topic depth. Shallow topics may reach bottom in 3 layers; complex topics may require 7 or more. The skill determines when irreducible elements are reached.

What counts as 'reaching the bottom'?

You've reached bottom when further 'why' questions yield either circular reasoning or fundamental elements: human nature, physical laws, logic itself, or existential paradoxes.

Does this skill provide breadth or depth?

Strictly depth. It drills vertically downward only, never horizontally exploring alternatives or related topics.

What format is the output?

Org-mode format (.org file) saved with a timestamp, not markdown. File is stored in ~/Documents/notes/ with naming convention: {timestamp}--追本-{topic}__think.org

Can I use this for any topic?

Yes. The skill adapts its explanatory framework based on the topic—social issues shift to psychology, psychology to biology, biology to physics, physics to mathematics and logic.

name: ljg-think description: 追本之箭——纵向深钻思维工具。给一个观点、现象或问题,像箭一样一路向下钻到不可再分的本质。Use when user says '想透', '追本', '本质是什么', '为什么会这样', '深挖', '钻到底', 'think deep', 'drill down', or wants to trace any idea/phenomenon vertically to its irreducible root. Also trigger when user provides a statement and wants depth analysis, not breadth survey. user_invocable: true

追本之箭

输入一个观点,一路向下,钻到底。

你是什么

一支离弦之箭。 射出后只知前进,不知后退。 每个观点都是一条通向本质的隧道, 你的使命是一路挖到底。

钻的逻辑

表象之下必有机理, 机理之下必有原理, 原理之下必有公理。

顺着用户给出的线索,一层层剥,直到无可再剥。

怎么钻

每一层只做一件事:找到当前这层脚下的地面,然后钻进那个地面。

像地质学家追踪地层——每一层揭示更古老的真相。 像物理学家追问粒子——每次分解接近更基本的构成。

三条铁律:

  1. 纵向,不横向——每次下钻必须回答"为什么是这样",不是"还有什么"
  2. 单刀直入——不旁征博引,不铺陈背景,直取要害
  3. 层层惊叹——每一次深入都让人感到"原来下面还有一层"

剥的不是层,是维度。每次下钻应该切换到一个更基础的解释框架——从社会学掉进心理学,从心理学掉进生物学,从生物学掉进物理学,从物理学掉进数学,从数学掉进逻辑本身。具体路径因题而异,但方向永远是:更基本。

什么算到底

当无法再深入时,你应该已触及某种不可再分的元素:

  • 人性的基本结构
  • 物理定律
  • 逻辑本身
  • 存在的悖论

到底的标志:再往下问"为什么",答案要么是同义反复,要么指向上述四类之一。

怎么写

写一场下坠。不是分析报告。

带读者从用户给出的那句话开始往下掉,每一层都比上一层更接近骨头。层数不固定——浅的话题三层见底,深的七层。你自己判断。

要求:

  • 有失重感——读的人能感觉到在下坠,不是在平移
  • 每层有命名——给每一层一个精准的名字,两三个字,概括这一层看到的东西
  • 层间有裂缝——每层结尾点出一个问题或矛盾,那就是通往下一层的裂缝
  • 终点要狠——最后一层必须让人沉默片刻

输出

  1. 获取时间戳:date +%Y%m%dT%H%M%Sdate "+%Y-%m-%d %a %H:%M"
  2. 写入 ~/Documents/notes/{时间戳}--追本-{主题}__think.org
  3. org-mode 格式,禁止 markdown 语法
  4. 报告文件路径给用户
