  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by fancyboi999 on GitHub. Read the source before you install it.

Installation

Install the Check Understanding AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/fancyboi999/ai-engineering-from-scratch-zh/tree/main/.claude/skills/check-understanding
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/fancyboi999/ai-engineering-from-scratch-zh.git /tmp/ai-engineering-from-scratch-zh
mkdir -p .claude/skills
cp -r /tmp/ai-engineering-from-scratch-zh/.claude/skills/check-understanding .claude/skills/check-understanding
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Check Understanding in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Check Understanding on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Check Understanding is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

检查理解程度

测试学习者对 AI Engineering from Scratch 已完成阶段的掌握情况。

触发方式

当用户说出类似下面的话时启用此 skill:

  • /check-understanding 3 或 /check-understanding deep-learning
  • “测验一下我对第 2 阶段的掌握情况”
  • “测试第 1 阶段”
  • “检查我对 transformer 的理解”
  • “我掌握第 3 阶段了吗”
  • “我准备好进入下一阶段了吗”

输入

接受阶段编号(0-19)或阶段名称作为参数。如果没有参数,列出全部 20 个阶段,并询问用户希望测试哪一阶段。

流程

第 1 步:解析阶段

解析参数。若为数字,验证它是否在 0 到 19(含)之间。数字超出范围时,告诉用户:阶段 [N] 不存在。有效阶段为 0-19。然后展示完整列表供其选择。若为名称或关键词,在上方阶段映射中查找。关键词不匹配任何条目时,告诉用户:未知阶段“[keyword]”。请从下面列表中选择:,并展示全部 20 个阶段。未提供参数时,要求用户从完整列表中选择。

第 2 步:读取阶段内容

如果仓库已克隆(当前目录或其父目录存在 phases/),找出 phases/<phase-dir>/ 下全部课程目录并读取每课的 docs/zh.md。如果未克隆,从 README 的 Contents 部分获取该阶段课程列表(获取 https://raw.githubusercontent.com/fancyboi999/ai-engineering-from-scratch-zh/main/README.md),再从同一 raw base URL 获取每课的 docs/zh.md。这些文档就是出题依据。

读取足够多的课程文档,以覆盖该阶段的完整广度。阶段课程很多(15+)时,优先读取具有代表性的分布:开头几课、中段几课和最后几课。

第 3 步:生成 8 道题

基于刚读取的课程内容,恰好生成 8 道选择题:

第 1-4 题:概念题(是什么/为什么) 这些题测试想法、定义和推理的理解。例如:

  • “X 的目的是什么?”
  • “Z 存在时为什么会发生 Y?”
  • “哪项陈述最准确地描述了 A 与 B 的关系?”
  • “X 解决了什么问题?”

第 5-8 题:实践题(怎么做/构建) 这些题测试应用知识和实现意识。例如:

  • “你会如何实现 X?”
  • “哪种方法能正确解决 Y?”
  • “构建 Z 的正确步骤顺序是什么?”
  • “若训练中观察到 X,应当怎么做?”

每题必须恰有 4 个选项,标记为 A、B、C、D,且只有一个正确选项。错误选项应当可信,但对认真学过材料的人应当明显不对。

给每道题标记其来源课程(例如“第 03 课:矩阵变换”)。

第 4 步:逐题展示

使用 AskUserQuestion 工具(或等效交互式提示)一次展示一道题。格式:

text
第 1/8 题(概念题)——来自第 03 课:矩阵变换

特征值的几何解释是什么?

A) 矩阵施加的旋转角度
B) 特征向量在变换中被缩放的倍数
C) 变换矩阵的行列式
D) 变换后矩阵的秩

等待用户作答后,才进入下一题。

答案隔离

在学习者回答当前题目之前,正确选项和解释必须保持私密。回复格式提示中绝不使用真实答案字母、可能答案或生成的答案分布。若需要纯文本提示,必须严格使用:请只回复一个字母:<A|B|C|D>。

第 5 步:记录与评分

持续记录:

  • 8 题中的正确总数
  • 每道错题:题号、用户答案、正确答案及来源课程

第 6 步:展示结果

所有 8 题完成后,展示得分和评级:

答对 7-8 题:已掌握 若为第 19 阶段(综合项目):你已掌握第 19 阶段,也是最后一个阶段。只有能够确认整个课程其余部分均已完成时(当前目录中的 LEARNING.md 路径表显示阶段 0-18 都是 Done 或 Skip),才能再加上 恭喜,你已完成全部课程。单次阶段测验不能证明整个课程已完成。 否则:你对第 N 阶段掌握扎实,可以进入第 N+1 阶段:[下一阶段名称]。

答对 5-6 题:接近掌握 基础扎实。继续前请复习以下具体内容: 随后列出错题关联的课程。

答对 3-4 题:正在形成理解 你的理解正在建立,但还需回顾以下课程: 随后列出每道错题及需重读的课程。

答对 0-2 题:重新开始 这个阶段还需要更多时间。请从头重新学习课程,重点关注: 随后列出所有未掌握的主题。

第 7 步:错题拆解

对用户答错的每一题,展示:

text
第 N 题:[题目文本,缩写]
你的答案:B
正确答案:C —— [正确选项文本]
原因:[用 1-2 句解释 C 为什么正确]
复习:第 NN 课 —— [课程名称] (phases/<phase-dir>/NN-<lesson-slug>/docs/zh.md)

第 8 步:下一步做什么?

最后提供三个选择:

  1. 重做本测验 —— 从同一阶段生成一组新的 8 道题
  2. 测试另一阶段 —— 选择其他阶段测试
  3. 解释一个主题 —— 询问任意错题涉及的概念

等待用户选择后再执行。

规则

  • 重考时,在题库耗尽前避免重复题目。题库耗尽后,才可为后续重考重排或改写题目。
  • 题目必须直接基于课程文档,不能基于通用知识。
  • 用户回答之前,不展示正确答案。
  • 学习者回答格式示例中不得出现真实答案字母;使用 <A|B|C|D> 作为占位符。
  • 题目文本保持简洁,最多一两句话。
  • 错误选项必须可信,不要设置玩笑答案。
  • 若一个阶段的课程正文待发布(以 docs/zh.md 文件为准),告诉用户:第 N 阶段尚未提供课程内容。请选择已完成的阶段进行测验。

Frequently asked questions

What does the Check Understanding AI skill do?

AI Engineering from Scratch 的阶段测验。用于“给我测验一下”、“测试阶段”、“检查我的理解”、“我掌握第 3 阶段了吗”,也支持 "quiz me", "test phase", "check my understanding", "do I know phase 3" 或 `/check-understanding <phase>`。

Why use Check Understanding on TypingMind?

Because you install it once and use it with any model. Check Understanding is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Check Understanding in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/fancyboi999/ai-engineering-from-scratch-zh/tree/main/.claude/skills/check-understanding. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Check Understanding?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Check Understanding?

As many as you like. As long as a model supports skills, you can use Check Understanding with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Check Understanding AI skill free?

Yes. It is published on GitHub by fancyboi999 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
