把一个名词或概念写成可使用的理解：先用普通话讲清它是什么、与相邻概念差在哪里，再说明它怎样运作、会改写什么判断，最后给出面对它时的行动抓手。USE WHEN 用户问 X 是什么、怎么理解、意味着什么、为什么重要、以后怎样判断或使用；尤其适合技术概念、制度、产品、角色、方法、规范与实践。NOT FOR 单纯查事实、公式证明、逐步操作教程、纵向因果深挖（用 ljg-think）或母题结构（用 ljg-structure）。.
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
# 把一个名词讲到能用
只给定义，读者可能记住了词，却仍不知道怎样认出它。只讲动词，读者又可能知道它做了什么，却不清楚它究竟是哪一类东西、边界在哪里。
`ljg-is` 把两者接起来：名词回答「它是什么」，让概念在认知地图里站稳；动词回答「它怎样起作用」，让概念在现实里动起来。真正完成的理解还要继续走一步：它改写了读者原来的什么判断，下次遇到它时又能怎样行动。
```text
它是什么，和什么不一样？
它靠什么动作产生结果？
知道这一点后，我不再怎样想？
下次遇到它，我先看什么、怎样做？
```
这四个问题是一条理解路径，不是四个正文栏目。文章要像一个人顺着疑惑把事情讲明白，而不是把答案依次填进表格。
赵汀阳的「动词」思想在这里仍然重要，但它是一副有条件的透镜。面对制度、平台、角色或规范，可以继续追问谁选择了这种做法，它怎样改变参与者；面对目标函数、递归这类技术概念，动词首先是对象自身的运算与作用。材料没有显示社会反制，就不把技术说明硬拽成制度批判。

## 成品标准
一篇合格解读会让读者发生四个连续变化：
- 能用一句普通话说出 X 属于什么，以及它与最容易混淆的对象差在哪里。定义要给边界，不能只给比喻或用途。
- 能顺着一个真实例子说明 X 怎样起作用。技术概念讲清输入、关键动作和结果；制度概念讲清参与者、规则怎样进入行动以及实际后果。只写对象真正具有的机制。
- 能指出自己原来哪种看法需要修改。认知变化必须由前面的定义和机制推出，不另起炉灶追求「深刻」。
- 能在一个具体情境里使用这番理解。行动指导要说清先看什么、怎样判断、何时调整，并能解释为什么。
正文从一个普通读者真的会有的疑惑、误解或使用场景进入，不强制编造人物故事。概念要尽早出现，例子负责验证解释，不负责制造戏剧性。
最后可以落在一句判断、一个行动原则或一个真实未决问题上。哪一种自然，由前文决定；问号不是深度证明。
默认写入：
```text
~/Context/{时间戳}--理解-{目标片段}__is.md
```
新成品使用 `ljg-is-v5` schema。正文使用两到四个随内容生出的标题和四到十个自然段，不把「是什么 / 怎样运作 / 认知改变 / 行动指导」直接用作四个栏目。

How to install
mdr add lijigang/ljg-skills/ljg-is@sha256:6b20221011330620The line at the top of this page pins the label v5.0.0, 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.
