What it does
Video Sync is an agent skill from itwanger/toBeBetterJavaer. 把「王二讲Agent」的 B 站视频链接同步到 docs/src/ai/video/readme.md，把抖音视频 ID 同步到 docs/src/.vuepress/agentInterview.ts 的 douyinVideoIds 映射表（页面会渲染成播放器）。当用户说 B 站更新了、抖音更新了、同步视频链接、把视频地址放进脚本、更新 readme 视频时使用。
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/douyin_extract.js` and `scripts/video_sync.py`).
It sits in Development, covering AI video generation and Technical documentation. It works with Python. The repository describes itself as: 一份通俗易懂、风趣幽默的Java学习指南，内容涵盖Java基础、Java并发编程、Java虚拟机、Java企业级开发、Java面试等核心知识点。学Java，就认准二哥的Java进阶之路😄.
When your agent uses it
- Tasks that involve AI video generation
- Tasks that involve Technical documentation
Example prompts
- “/video-sync”
Requirements
- Python 3
- Node.js
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 拉 B 站列表：python3 .claude/skills/video-sync/scripts/video_sync.py bili。接口无需登录，NEW 标记的就是 readme 还没引用的视频。
- 拉抖音列表：抖音必须登录，curl 和内置浏览器拿不到数据。用 Claude in Chrome 打开抖音主页，关掉登录弹窗，滚到底部出现「暂时没有更多了」，再用 javascript_tool 执行…
- 看缺口：python3 .claude/skills/video-sync/scripts/video_sync.py status，输出 readme 里缺 B 站链接的题目和映射表里缺抖音 ID 的脚本，缺 meta 的会单独标出来。
- 人工配对：按视频标题和简介对到脚本文件名，写成两个 TSV 映射文件，每行 脚本名BV号 或 脚本名抖音视频ID。只配缺口里的条目。
- 写入：python3 .claude/skills/video-sync/scripts/video_sync.py apply --bili B站映射.tsv --douyin 抖音映射.tsv。脚本幂等，重复跑不会重复追加；缺 meta 的脚本会被跳过并提示。
- 汇报三类剩余：readme 有题但两边都没视频的、视频有但没脚本的、两边有视频但 readme 没题的。这三类由用户决定要不要补。
What it can do on your machine
Read from SKILL.md and the folder at commit b1b66b5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (JavaScript and Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
bilibili.com
Also links to:
douyin.comspace.bilibili.comjavabetter.cn
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Video Sync loads about 445 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 102 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 102 words (~445 tokens).
- name
- video-sync
Files
SKILL.md and 2 other files (scripts) in .claude/skills/video-sync of itwanger/toBeBetterJavaer.
- SKILL.md
- scripts/douyin_extract.js

When should I use Video Sync?
Video Sync fits situations like: tasks that involve AI video generation; tasks that involve Technical documentation.
How do I install Video Sync in Claude Code?
Run `npx skills add itwanger/toBeBetterJavaer --skill video-sync -a claude-code`. Or copy the skill folder (.claude/skills/video-sync in itwanger/toBeBetterJavaer) into .claude/skills/video-sync in your project. Claude Code loads it when a task matches its description.

Can I use Video Sync in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add itwanger/toBeBetterJavaer --skill video-sync -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/video-sync, .gemini/skills/video-sync, .github/skills/video-sync and .opencode/skills/video-sync in your project.
What does Video Sync need to run?
Going by SKILL.md and its folder, Video Sync needs JavaScript and Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3; Node.js.
Does Video Sync access the network?
SKILL.md names 4 domains. In commands or code: bilibili.com; the agent is likely to contact it when it follows the instructions. As links in the text: douyin.com, space.bilibili.com and javabetter.cn. This is read from the text; nothing was executed.
Is Video Sync safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Video Sync use?
No licence was found for Video Sync or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Video Sync use?
About 445 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
