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: benefits_claims_controller.rb
    path of file: ./repos/vets-api/app/controllers/v0
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'lighthous
    
    def index
      claims = service.get_claims

      check_for_birls_id
      check_for_file_number

      tap_claims(claims['data'])

      render json: claims
    end
