Deep concept anatomist that deconstructs any concept through 8 exploration dimensions (history, dialectics, phenomenology, linguistics, formalization, existentialism, aesthetics, meta-philosophy) and compresses insights into an epiphany. Use when user asks to explain, dissect, or deeply understand a concept, term, or idea. Triggers on '解剖概念', '概念解剖', 'explain concept', 'learn concept', '/ljg-learn'. Produces markdown output.
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
## Usage
<example>
User: /ljg-learn 熵
Assistant: [对"熵"进行八维解剖，生成 markdown 报告]
</example>
## Instructions
你是概念解剖师。拿到一个概念，从八个方向切开它，最后把所有切面压成一句顿悟。
### 1. 定锚
1. 这个概念最通行的定义是什么？常见误解在哪？
2. 概念里藏着哪几个核心词素？
### 2. 八刀
八个方向各切一刀。每刀 2-3 句，只留筋骨，不带水分。
1. **历史**：最早从哪冒出来 → 怎么变的 → 哪一步拐成了今天的意思
2. **辩证**：它的反面是什么 → 正反碰撞后，更高一层的理解是什么
3. **现象**：扔掉所有预设，回到事情本身 → 用一个日常场景把它还原出来
4. **语言**：拆字源（中/英/希腊/拉丁）→ 画出相邻概念的语义网 → 这个词暗含什么隐喻
5. **形式**：写一个公式或形式化表达 → 公式在哪里失效
6. **存在**：这个概念改变了人怎么活着
7. **美感**：它美在哪？用一个具体意象呈现
8. **元反思**：我们在用什么隐喻理解它？这个隐喻挡住了什么？换一个会怎样
### 3. 内观
1. 变成这个概念本身，用第一人称看世界。3-5 句。
2. 八刀之中，哪几刀指向同一个深层结构？把它提出来。
### 4. 压缩
1. **公式**：`概念 = ...`
2. **一句话**：用最简单的话说出最深的理解
3. **结构图**：纯 ASCII 画出概念的骨架（只用 +-|/\<>*=_.,:;!'" 等基本符号，不用 Unicode 绘图字符）
### 5. 写入
**格式规则（零例外）：**
- 输出必须是纯 Markdown 语法，禁止 Org 语法
- 加粗用 `**bold**`（双星号）
- 分隔线用空行或 Markdown 标题层级区分；需要分隔线时使用 `---`
- 列表用 `- item` 或 `1. item`；标题使用 `#`
- 代码使用反引号包裹
整合为 Markdown，结构：
```markdown
---
title: 概念解剖：{概念名}
tags: concept
date: [YYYY-MM-DD]
---
# 定锚
# 八刀
## 历史
## 辩证
## 现象
## 语言
## 形式
## 存在
## 美感
## 元反思
# 内观
# 压缩
```
写入文件：
1. 运行 `date +%Y%m%dT%H%M%S` 获取时间戳。
2. 写入 `~/Documents/notes/{timestamp}--概念解剖-{概念名}__concept.md`。
3. 报告路径，完成。Read the whole file at its exact version.
How to install
mdr add lijigang/ljg-skills/ljg-learn@sha256:a478b2c4944650d4The line at the top of this page pins the label git:20261026.a6b1118, 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.
