What it does
Env Setup is an agent skill from wwwzhouhui/skills_collection. Checking and provisioning the machine's environment for the video-agent-kit plugin — probing for ffmpeg/ffprobe that actually carry the encoders and filters we render with (libx264/aac/libmp3lame, libass, libfreetype), python packages (mcp, cv2, numpy, PIL, jieba, fontTools, scenedetect) in the interpreter Claude Code really uses, a CJK font whose cmap truly covers Chinese, and which speech channel is in play (under ZCode the official channel needs no local key) — then installing what is missing (China mirrors by…
Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/env_doctor.py`).
It sits in Media & Creative, covering Transcription and Video production. It works with FFmpeg, Python, OpenCV and Model Context Protocol. The repository describes itself as: 本项目是个人开发的 Claude Code Skills 集合，提供实用的技能工具，助力提升开发效率和内容创作。 分享一些好用的 Claude Code Skills，自用、学习两相宜，适用于 Claude Code v2.0 及以上版本。
When your agent uses it
- Asked to 检查环境 / 装依赖 / 配国内源 / setup / doctor
- Tasks that involve Transcription

Example prompts
- “libx264”

Requirements

7 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit b98f166. 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 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pippython3apt-getbrewconda
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:
pypi.tuna.tsinghua.edu.cnmirrors.tuna.tsinghua.edu.cnmirrors.aliyun.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
VE_SPEECH_MCP_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Env Setup loads about 3.5k tokens when it runs. Until then it costs about 249 tokens; SKILL.md has 1,846 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:63
environment** (a project `.env` is untrusted for those; it could otherwise - NoteRuns commands with sudoSKILL.md:178
code change, and not `sudo cp` into `/usr/share/fonts`.
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 1,846 words (~3,486 tokens).
“Claude Code is a generic harness — it ships no ffmpeg, no CJK font, no python media stack. Everything this kit needs is per-machine, and provisioning it is this skill's job. A run started on a half-provisioned machine does not…”

Questions about Env Setup
What does Env Setup do?
Checking and provisioning the machine's environment for the video-agent-kit plugin — probing for ffmpeg/ffprobe that actually carry the encoders and filters we render with (libx264/aac/libmp3lame…. Env Setup is an agent skill from wwwzhouhui/skills_collection.
When should I use Env Setup?
Env Setup fits situations like: asked to 检查环境 / 装依赖 / 配国内源 / setup / doctor; tasks that involve Transcription; tasks that involve Video production.
How do I install Env Setup in Claude Code?
Run `npx skills add wwwzhouhui/skills_collection --skill env-setup -a claude-code`. Or copy the skill folder (video-agent-kit/skills/env-setup in wwwzhouhui/skills_collection) into .claude/skills/env-setup in your project. Claude Code loads it when a task matches its description.
How do I install Env Setup in Codex?
Run `npx skills add wwwzhouhui/skills_collection --skill env-setup -a codex`. Or copy the skill folder (video-agent-kit/skills/env-setup in wwwzhouhui/skills_collection) into .agents/skills/env-setup in your project. Codex loads it when a task matches its description.
Can I use Env Setup 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 wwwzhouhui/skills_collection --skill env-setup -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/env-setup, .gemini/skills/env-setup, .github/skills/env-setup and .opencode/skills/env-setup in your project.
What does Env Setup need to run?
Going by SKILL.md and its folder, Env Setup needs Python for the scripts in its folder, the command-line tools its instructions call (pip, python3, apt-get, brew and conda) and credentials named VE_SPEECH_MCP_TOKEN. Our summary lists: Python 3; A credential in VE_SPEECH_MCP_TOKEN.
Does Env Setup access the network?
SKILL.md names 3 domains. In commands or code: pypi.tuna.tsinghua.edu.cn, mirrors.tuna.tsinghua.edu.cn and mirrors.aliyun.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Is Env Setup safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file; runs commands with sudo), nothing it rates as a warning. 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 Env Setup use?
No licence was found for Env Setup or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Env Setup use?
About 3.5k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Env Setup?
Skills that share tags, products or a category with Env Setup: Cassette Video Edit (Cassette-Editor/oh-my-cassette, 157 stars), Kinocut (KyaniteLabs/kinocut, 192 stars), Kinocut Repurpose (KyaniteLabs/kinocut, 192 stars) and Ffmpeg Skill (kajisho5/ffmpeg-skill, 1.9k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
