After installing shell integration, you get these automated features:

1. Auto-apply Environment Variables

   ccenv use work      # Direct command mode
   ccenv list -i       # Interactive mode
   # Both automatically set environment variables, no manual eval needed!

2. Persistent Environment

   # New terminals automatically restore last environment
   echo $ANTHROPIC_BASE_URL  # Auto-loaded

3. Project-level Environment

   # Create .ccenv file in project directory
   echo "work" > .ccenv
   cd project  # Automatically switches to work environment

If you prefer not to install automatic integration:

# Manually apply to current shell
eval "$(ccenv current --export)"

# Or load specific environment
eval "$(ccenv use work --source)"

ccenv manages these environment variables for Claude Code:

• ANTHROPIC_BASE_URL - Anthropic API base URL
• ANTHROPIC_API_KEY - Anthropic API key

• ~/.ccenv/config.json - Environment configurations
• ~/.ccenv/current_env - Current environment persistence file
• .ccenv - Project-level environment configuration file

# Set up multiple environments
ccenv add work
ccenv add personal
ccenv add mirror

# Install automation
ccenv install

# 🎯 Interactive mode - navigate with arrow keys
ccenv list -i
# Select environment with Enter key
# ✓ Switched to environment: work
# 🎉 Environment variables automatically applied!

# Or direct command mode
ccenv use work
echo $ANTHROPIC_BASE_URL  # https://api.work.com

# New terminals automatically restore environment
# Projects with .ccenv files auto-switch environments
