When your CLI command needs to accept user input, create a CommandSettings class and decorate its properties with attributes to define the interface. Use [CommandArgument] for positional parameters (required with <name> or optional with [name]), positioning them by index. For named parameters, use [CommandOption] with short and long forms like -c|--count.
Add [Description] attributes to generate helpful usage text, and [DefaultValue] to provide sensible defaults. Boolean options automatically work as flags—users specify them to set true, omit them for false. If you need to accept multiple values, use an array type on the last argument. The framework automatically generates help and validates user input based on these declarations.
