wdkns-skills
Turns a Bilibili or YouTube lecture or tutorial into a structured, figure-rich LaTeX course note and PDF, so you get study notes without rewatching the video. It also cleans up the video's subtitles and draws clear visuals for tensor and matrix formulas.

Skills 一览
youtube-render-pdf：将 YouTube 讲座、教程或技术分享整理为结构化、配图丰富的中文 LaTeX 讲义，并编译交付最终 PDF。bilibili-render-pdf：面向 Bilibili 视频生成中文 LaTeX 讲义和最终 PDF，并针对字幕缺失、登录高清与分 P 视频提供专门处理流程。
subtitle-refine：在保持时间轴同步和原意不变的前提下精修 ASR 生成的中文 SRT 字幕，并通过校验脚本产出可发布的完整字幕。tensor-formula-viz：把张量、矩阵或向量公式及其代码路径转换为形状对齐、语义清晰且适合演示的计算示意图。
video-render-pdf skills
这个仓库托管两个 Codex skill，用于将视频讲座转换为结构化的中文 LaTeX 讲义和最终 PDF。
| Skill | 平台 | 说明 |
|---|---|---|
youtube-render-pdf | YouTube | 原始版本，利用 YouTube CC 字幕和章节结构 |
bilibili-render-pdf | Bilibili (B站) | 适配 B 站的字幕缺失、登录高清、分P视频等特点 |
两个 skill 共享相同的写作规则、配图策略和 LaTeX 模板，但在素材获取阶段有平台特定的差异。
Bilibili 版的核心差异
- 字幕三级回退：CC 字幕 → Whisper 语音转写 → 纯视觉模式（B 站大量视频无 CC 字幕）
- 登录获取高清：1080P+ 需要 cookies（
yt-dlp --cookies-from-browser chrome） - 分P视频处理：自动检测多 P，询问用户处理范围
- 平台话术过滤：额外排除"一键三连"、"关注投币"等非教学内容
- 额外依赖：
whisper（openai-whisper）用于语音转写
共同特点
- 以视频真实教学内容为主，而不是只依赖字幕转写
- 优先使用原始视频封面作为首页封面图
- 按教学价值提取关键画面、图表、公式和代码片段
- 生成带
\section{}/\subsection{}结构的完整.tex - 最终必须落到可交付的 PDF
使用方式
如果你想在本地 Codex 环境中使用这些 skill，可以把对应目录放到你的技能目录中：
mkdir -p ~/.codex/skills
# YouTube 版
cp -R skills/youtube-render-pdf ~/.codex/skills/
# Bilibili 版
cp -R skills/bilibili-render-pdf ~/.codex/skills/
然后在 Codex 中使用对应 skill 处理视频链接，请求生成讲义 .tex 和最终 PDF。
外部依赖
| 工具 | 两个 skill 都需要 | 仅 Bilibili 版需要 |
|---|---|---|
yt-dlp | ✓ | |
ffmpeg | ✓ | |
xelatex (TeX Live + CTeX) | ✓ | |
magick (ImageMagick) | ✓ | |
whisper (openai-whisper) | ✓ |
此外，运行 skill 的 coding agent 必须具备一定的读图能力，否则很难选择关键帧，很难做到图文align（即至少是一个还不错的 vlm model，ps. MiniMax 2.7 只是一个纯文本模型）。
subagents 的触发
- codex 中对于
spwan_agent的触发，规定的比较死，"Only use spawn_agent if and only if the user explicitly asks for sub-agents, delegation, or parallel agent work."，即需要我们在 query 中显式地要求，才可以触发 subagents
$youtube-render-pdf https://www.youtube.com/watch?v=vXb2QYOUzl4 请 spwan 多 sub agents 执行，隔离上下文，避免 master agent 的“上下文焦虑”， 形成一个完整全面的 pdf：
- 1 个 outline agent：先定全局目录、术语、符号表、章节边界等
- 5 个 writer agents：各自直接写成完整章节草稿，落盘成 section_*.tex
- 1 个 figure agent：单独负责抽帧、筛图、crop、脚本生成新的示意图、图注和时间脚注等；
- 1 个 consistency agent：检查重复定义、前后术语不一致、章节衔接断裂
tips
- 强烈建议在 codex 基于这个 skill 给出第一版结果之后，增加一个follow up question：
spwan 一个独立的reviewer agent，基于原始字幕文件，check 是否有重要、细节及有趣等一切有意的信息的漏召回，仅反馈，不修改，不断交互，直至reviewer agent 觉得 tex 信息已完备。- 以缓解 ai extraction/summary 的共性问题，就是召回不足；

@zarazhangruiQuestions about wdkns-skills.
Install it with the command on its page. It includes bilibili-render-pdf, subtitle-refine, tensor-formula-viz. Its skills do not fire on their own yet. Free and open source.
- What is wdkns-skills?
- wdkns/wdkns-skills is a plugin of skills that turns video lectures into LaTeX PDF notes using speech-to-text, with refined subtitles and tensor formula visuals. Use it when working from Bilibili or YouTube lecture videos.
- How do I install wdkns-skills?
- Run these in Claude Code: npx -y skills add wdkns/wdkns-skills --agent claude-code. Then prompt normally.
- Does wdkns-skills auto-invoke its skills?
- Not yet. It is indexed on Flowy as a plain plugin.
- Is wdkns-skills free?
- Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.
- Which coding agents can use wdkns-skills's skills?
- wdkns-skills installs in Claude Code, and its skills also install in Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI. Each skill's page has the install command. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
