🚀 Quick Start

Step 1: Environment Setup

Install Git for Windows (includes Git Bash)
Install Node.js (LTS version recommended, ≥ 18)
Open PowerShell as Administrator and set environment variable:

setx SHELL "C:\Program Files\Git\bin\bash.exe"

Restart your computer (required for changes to take effect)

Step 2: Install Claude Code CLI

After restarting, open a new terminal window:

npm install -g @anthropic-ai/claude-code

⚠️ VPN Users: Please ensure TUN mode is enabled throughout the installation and usage process, otherwise you may not be able to connect to Claude services.

Step 3: Log in to Claude Code

Using Official Account

claude

A browser window will open for authorization. Log in and copy the token back to the terminal.

Using 🔑 Third-Party API

If you're using a third-party API, configure it in the extension:

Press Ctrl+Shift+C to open the chat interface
Click the settings button ⚙️ in the top right corner
Check "Use Custom API Endpoint"
Enter your API key in the API Key field (e.g., sk-ant-xxxxxxxxxx)
Enter the API address in the Base URL field (e.g., https://v3.codesome.cn)
Settings are saved automatically. "Settings updated successfully" confirms the configuration

Switch back to official account: Uncheck "Use Custom API Endpoint".

💡 Tips:

If the API key is incorrect, chat will show "processing" until timeout

You can switch between official account and third-party API anytime via the toggle

💡 This extension supports various third-party API services (e.g., v3.codesome.cn, openrouter.ai). Please consult your API provider for the specific URL.

Step 4: Install the Extension

❓ FAQ

Q: Getting "No suitable shell found" error?

Make sure Git for Windows is installed
Run as administrator: setx SHELL "C:\Program Files\Git\bin\bash.exe"
Restart your computer (required for changes to take effect)

If the problem persists, try:

Open system environment variables (Win + X → System → Advanced system settings → Environment Variables)
Ensure PATH contains C:\Program Files\Git\cmd
Restart your computer

Q: Third-party API configured but chat not responding?

Claude Code CLI sometimes needs to be initialized in the command line first. Run in PowerShell:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass -Force
$Env:ANTHROPIC_API_KEY  = "sk-xxxxxxxxxxxxxxxxxxxxxxxx"
$Env:ANTHROPIC_BASE_URL = "https://v3.codesome.cn"
claude

If the problem persists, try updating Claude Code CLI:

npm install -g @anthropic-ai/claude-code@latest

Q: Third-party API stops working after computer restart?

Environment variables $Env:ANTHROPIC_API_KEY and $Env:ANTHROPIC_BASE_URL are temporary and will be lost after restart.

Two solutions:

Option 1: Reset after each restart

$Env:ANTHROPIC_API_KEY  = "your API Key"
$Env:ANTHROPIC_BASE_URL = "https://v3.codesome.cn"
claude

Option 2: Set as permanent environment variables (run as administrator)

setx ANTHROPIC_API_KEY "your API Key"
setx ANTHROPIC_BASE_URL "https://v3.codesome.cn"
# Restart computer for changes to take effect

Q: Getting "rg: command not found" error?

This is optional and doesn't affect normal usage. If you want to install ripgrep for better search performance:

# In Git Bash:
curl -L https://github.com/BurntSushi/ripgrep/releases/download/14.1.0/ripgrep-14.1.0-x86_64-pc-windows-msvc.zip -o ripgrep.zip
unzip ripgrep.zip && mkdir -p ~/bin
cp ripgrep-14.1.0-x86_64-pc-windows-msvc/rg.exe ~/bin/
echo 'alias rg="~/bin/rg"' >> ~/.bashrc && source ~/.bashrc

Note: The extension's built-in Grep tool works fine without ripgrep.

Q: Getting "File has been unexpectedly modified" error when Claude edits files?

This error occurs when VS Code/Cursor's auto-save feature modifies files between Claude's Read and Edit operations.

Solution: Disable auto-save

Add this to your VS Code/Cursor settings (settings.json):

"files.autoSave": "off"

Or use a less aggressive option:

"files.autoSave": "onWindowChange"

Why this happens:

Claude reads a file and stores its content hash
Auto-save triggers and modifies the file on disk
Claude tries to edit the file, but the hash no longer matches
Claude reports "File has been unexpectedly modified"

Other settings that can cause this issue:

editor.formatOnSave: true - Formatters modify file content on save
files.trimTrailingWhitespace: true - Removes trailing spaces on save
files.insertFinalNewline: true - Adds newline at end of file

If you need these features, consider disabling them temporarily when using Claude Code.
