mobilevc-installer

Install and run MobileVC for the user. The user's dev machine becomes the Claude Code backend; the phone runs the official client app and connects to it over LAN or through the public Relay flow.

What you do

Run these steps in order. Stop and report to the user as soon as anything fails.

Step 1 — Preflight

Before installing, check the environment. Run these commands and confirm:

node --version    # require >= 18.0.0
npm --version

If node is missing or older than 18, STOP and tell the user how to install Node.js (brew install node, nvm install 20, or https://nodejs.org). Do NOT proceed.

Step 2 — Install the npm package

Try the global install first:

npm install -g @justprove/mobilevc

If it fails with EACCES or permission errors, do NOT use sudo. Instead suggest one of:

• npm config set prefix ~/.npm-global && export PATH=~/.npm-global/bin:$PATH then re-run install
• nvm use <version> if the user has nvm
• npm install --prefix ~/.local @justprove/mobilevc and add ~/.local/bin to PATH

Verify:

mobilevc --help

Step 3 — First-run setup (interactive)

Tell the user that mobilevc start will ask three questions on first run:

1. Language — zh or en
2. Port — default 8001. Pick something else if 8001 is busy.
3. Auth token — any string the user wants. The phone client will need this to connect.

If the user has not picked a token yet, suggest something memorable but non-trivial (e.g. mvc- plus 8 random chars).

Important: token input is hidden in the terminal. Tell the user to type the token normally and press Enter even though no characters are shown.

Step 4 — Start the backend

mobilevc start

This will:

• Run mobilevc setup if no config exists yet
• Spawn the prebuilt server binary in the background (logs in ~/.mobilevc/logs/)
• Print a LAN QR code in the terminal that encodes <host>:<port> + auth token

If start fails, run mobilevc logs and surface the relevant error to the user. Common issues:

• Port already in use → mobilevc stop then change port via mobilevc setup
• Binary missing → reinstall via npm install -g @justprove/mobilevc --force

Step 5 — Direct the user to install the phone client

Tell the user (verbatim, in the user's preferred language):

后端已启动。请在手机上：
1. 打开 MobileVC 官网首页：https://www.mobilevc.top
2. iOS 通过官网上的 TestFlight 链接安装
3. Android 通过官网上的 APK 下载入口安装
4. 如果官网打不开，先切换到国内网络环境后再试
5. 打开 MobileVC App，扫描终端里刚刚打印的二维码

(English variant if the user is using English.)

Step 6 — Done

Confirm the running state:

mobilevc status

Tell the user the helper commands they will need later:

• mobilevc status — check if backend is alive
• mobilevc logs -f — follow logs
• mobilevc stop — stop backend
• mobilevc restart — restart with same config
• mobilevc setup — reconfigure (port / token / language)
• mobilevc public --relay wss://relay.mobilevc.top:9443 — connect through the official Relay when the phone is not on the same WiFi

Important rules

• Do NOT clone the MobileVC source repo unless the user explicitly asks to develop on it. This skill is for end-users who only want to RUN MobileVC.
• Do NOT ask the user for APNS keys or any backend secrets. The npm-bundled binary is self-contained for LAN usage; APNS push is only required if the user is self-hosting a public deployment, which is out of scope here.
• Do check Node.js version first. Almost all install failures upstream of mobilevc start are Node version or PATH issues.
• Do keep the QR code output visible — that's the primary user-facing artifact.
