EXAMPLES:
    cc-switch add my-config sk-ant-xxx https://api.anthropic.com
    cc-switch add my-config -t sk-ant-xxx -u https://api.anthropic.com
    cc-switch add my-config -t sk-ant-xxx -u https://api.anthropic.com -m claude-3-5-sonnet-20241022
    cc-switch add my-config -t sk-ant-xxx -u https://api.anthropic.com --small-fast-model claude-3-haiku-20240307
    cc-switch add my-config -t sk-ant-xxx -u https://api.anthropic.com --max-thinking-tokens 8192
    cc-switch add my-config -i  # Interactive mode
    cc-switch add my-config --force  # Overwrite existing config
    cc-switch list
    cc-switch remove config1 config2 config3
    cc-switch current  # Interactive mode to view and switch configurations
    cc-switch  # Enter interactive mode (same as 'current' without arguments)

SHELL COMPLETION AND ALIASES:
    cc-switch completion fish  # Generates shell completions
    cc-switch alias fish       # Generates aliases for eval

    These aliases are available:
    - cs='cc-switch'                              # Quick access to cc-switch
    - ccd='claude --dangerously-skip-permissions' # Quick Claude launch

    To use aliases immediately:
    eval \"$(cc-switch alias fish)\"    # Add aliases to current session

    Or add them permanently:
    cc-switch completion fish > ~/.config/fish/completions/cc-switch.fish
    echo \"alias cs='cc-switch'\" >> ~/.config/fish/config.fish
    echo \"alias ccd='claude --dangerously-skip-permissions'\" >> ~/.config/fish/config.fish

    Then use:
    cs current    # Instead of cc-switch current
    ccd           # Quick Claude launch"
