Overview

Detects ‘definition :method_name` DSL calls inside runner modules where no corresponding `def method_name` exists. A mismatched definition means the framework advertises a runner function that doesn’t exist, causing a NoMethodError at dispatch time.

Examples:

# bad
module Runners
  module Foo
    definition :do_work
    # missing: def do_work
  end
end

# good
module Runners
  module Foo
    definition :do_work

    def do_work
      { success: true }
    end
  end
end
