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: tool.rb
    path of file: ./repos/massa/lib/massa
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Massa
  class Tool
    attr_reader :name, :description, :gem, :command, :required

    def initialize(name, attribu
    
      def custom_tools
        # Returns an empty hash if config file is empty
        @custom_tools ||= YAML.load_file(config_file_from_project) || {}

      # When there is no config file in the project
      rescue Errno::ENOENT
        {}
      end
