Integrating Claude Code

Anthropic's official CLI AI coding tool. It supports code generation, refactoring, debugging, and automated commits, and connects to Calgine Tokens via the Anthropic-compatible protocol.

Claude Code is a CLI AI coding assistant from Anthropic that lets you interact with your codebase in natural language and complete the full development workflow from requirements to commits.

Prerequisites

1. Sign up at the Calgine Tokens Console.
2. Go to Workspace → API Tokens, click "Add Token", and copy the API Key after creation (starts with sk-).

Setting	Value
ANTHROPIC_BASE_URL	https://api.calgine.com.cn/anthropic
ANTHROPIC_AUTH_TOKEN	The API token you created in the console

Installation & Configuration

1. Install Node.js: make sure Node.js 18+ is installed:

   node -v

2. Install Claude Code:

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

3. Set environment variables (choose one):

   macOS / Linux (zsh)

   echo 'export ANTHROPIC_AUTH_TOKEN="sk-your-token"' >> ~/.zshrc
   echo 'export ANTHROPIC_BASE_URL="https://api.calgine.com.cn/anthropic"' >> ~/.zshrc
   source ~/.zshrc

   macOS / Linux (bash)

   echo 'export ANTHROPIC_AUTH_TOKEN="sk-your-token"' >> ~/.bashrc
   echo 'export ANTHROPIC_BASE_URL="https://api.calgine.com.cn/anthropic"' >> ~/.bashrc
   source ~/.bashrc

   Windows (PowerShell)

   [Environment]::SetEnvironmentVariable("ANTHROPIC_AUTH_TOKEN", "sk-your-token", "User")
   [Environment]::SetEnvironmentVariable("ANTHROPIC_BASE_URL", "https://api.calgine.com.cn/anthropic", "User")

   Alternatively, write them into Claude Code's config file ~/.claude/settings.json:

   {
     "env": {
       "ANTHROPIC_AUTH_TOKEN": "sk-your-token",
       "ANTHROPIC_BASE_URL": "https://api.calgine.com.cn/anthropic"
     }
   }

4. Enter your project directory and launch:

   cd your-project-folder
   claude

Verify the Setup

After launching claude, ask any question in the interactive prompt (e.g., "describe the current project structure"). A normal response means the integration works. You can also run /status to check the current Base URL and model.

Common Commands

Command	Description
claude	Start interactive mode
claude "task description"	Run a one-off task
claude commit	Generate a Git commit message and commit
/help	List all available commands
/clear	Clear the current conversation history
/model	Switch the model in use

Recommended Models

Scenario	Recommended Model
Everyday coding assistance	claude-sonnet-4-5
Complex tasks & deep refactoring	claude-opus-4-5-20251101

Note

Claude Code's agent mode calls the model frequently and consumes far more tokens than regular chat. Keep an eye on your quota and rate limits — see Rate Limits.
