  • 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.

  • 7 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by LZheng0411 on GitHub. Read the source before you install it.

Installation

Install the Lzheng Video Lessons 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/LZheng0411/Lzheng-fitness/tree/main/skills/lzheng-video-lessons
  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.

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/LZheng0411/Lzheng-fitness.git /tmp/Lzheng-fitness
mkdir -p .claude/skills
cp -r /tmp/Lzheng-fitness/skills/lzheng-video-lessons .claude/skills/lzheng-video-lessons
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Lzheng Video Lessons 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 Lzheng Video Lessons 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 Lzheng Video Lessons 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.

Lzheng 分段视频教学

用户给链接或本地视频并要求“分段讲解、知识库教学、接入健身系统”时使用。沿用当前用户的素材、目标与发布授权,不要求重新确认已有决定。创建 Skill 本身不代表发布新课程。

1. 获取并核对来源

优先复用已核对的媒体、转写和时间戳;有 lzheng-video-learning 时用它的获取/转写工具,个人环境也可用已安装的 douyin-question-distiller。没有这些工具时接收用户本地视频和转写,保留同样数据契约。不要绕过登录、验证码、付费或访问限制;同一临时媒体地址失败最多重新获取一次,失败条目记录原因,继续可独立完成部分。

在用户 workspace 中保存来源 URL、作品 ID、讲者/上传者、时长、媒体哈希、转写和关键帧。运行材料不得进入 Skill 或公开仓库。逐段核对时间、数字、单位、动作版本与否定词;只做过机器转写/抽帧就如实写明,不声称逐字听校。

2. 编写章节

读取 讲解与数据契约。章节必须有精确 start/end、稳定 ID、目标、详细步骤与步骤时间点。分段按教学意义,不固定章节数、不等分时间。允许未收录片段,但要在 coverage_note 说明;章节不能重叠、越界。

正文直接讲“你怎么准备、怎么做、为什么、怎样判断、哪里容易错”,不用“作者演示了/他说了”代替解释。署名和证据放来源区。不要补造片中没有的组数、重量或通用结论;来源建议与额外解释分开标注,存疑处保留待核对。

3. 生成可试用课程

python scripts/lesson.py validate --input <lesson.json>

核对通过后:python scripts/lesson.py build --input <lesson.json> --out <新课程目录> [--media <mp4> --poster <jpg>]

工具只接受新输出目录,避免覆盖已有课程和学习笔记。更新使用同一 lesson.id/chapter.id 并生成新版本目录,验收后替换注册入口,保留旧版便于回退。默认只链接原视频;复制媒体需要 lesson.json 记录 media_rights_basis。开源包不附带原视频、截图、完整转写或私人资料。

播放器保持黑白、单列浮动目录、编号步骤、原片起止时间、到终点暂停、重播/循环、步骤跳转、按课程保存本机笔记。缺少媒体明确显示“仅原视频链接”,不留假播放器。真实媒体必须验证可解码、非黑屏、拖动与片段终点;浏览器后台限流时不承诺逐帧剪辑精度。需要独立片段文件时可由 ffmpeg 导出,但默认复用单原片的时间窗口,避免重复占用空间。

4. 接入与复用

python scripts/lesson.py integrate --html <工作台.html> --lesson <课程目录> --backup-dir <备份目录> [--apply]

先预检,已获接入授权再 apply。课程必须位于工作台目录树内。只按稳定 ID 更新 knowledge-lessons-data;支持现有个人工作台 UI,其他模板安装通用知识库对话框。保留 workbench-data、账号配置和已有知识;不自动匹配相似动作,精确动作联动交给现有适配器,需逐个核对变式。

5. 验收与发布

读取 接入与发布。先完成本地检查与可审阅页面。已授权发布就继续现有发布器;未授权仅给预览,不把“入库”推断成上传许可。媒体再分发范围与代码许可分别判断。

发布需包含课程 HTML、chapters.js 和授权媒体/海报;以依赖清单为准。不得让公开匿名工作台夹带私人课程。上线后逐文件 HTTP/哈希核验,并实际打开知识库、选段、播放/终点、返回。分别记录 source_verified、lesson_built、integrated、release_prepared、deployed、online_verified;脚本完成不等于用户已学会或练过。

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Why use Lzheng Video Lessons on TypingMind?

Because you install it once and use it with any model. Lzheng Video Lessons 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 Lzheng Video Lessons in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/LZheng0411/Lzheng-fitness/tree/main/skills/lzheng-video-lessons. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Lzheng Video Lessons?

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 Lzheng Video Lessons?

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

Is the Lzheng Video Lessons AI skill free?

Yes. It is published on GitHub by LZheng0411 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.
