You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cli_base.rb
    path of file: ./repos/stealth/lib/stealth
    
    the code of the file until where you have to start completion: # coding: utf-8
# frozen_string_literal: true

module Stealth
  module CliBase
    def define_commands(&blk)
      class_eval(&blk) if block_given?
    end

    def banner(command, nspace = true, subcommand = false)

    
    def handle_argument_error(command, error, args, arity)
      name = [(namespace == 'stealth:cli' ? nil : namespace), command.name].compact.join(" ")

      msg = "ERROR: \"#{basename} #{name}\" was called with "
      msg << "no arguments"               if     args.empty?
      msg << "arguments " << args.inspect unless args.empty?
      msg << "\nUsage: #{banner(command).inspect}"

      raise Thor::InvocationError, msg
    end
