You could also wrap this up in a service class so it can be unit-tested and used across your rake tasks:

# frozen_string_literal: true

class RakeConfirmDialog
  def initialize(question)
    @question = "#{question} (y/n)"
    @answer = "".inquiry
  end

  def confirm!
    prompt until (proceed? || abort?)

    respond

    proceed?
  end

  private

  def prompt
    STDOUT.puts @question

    @answer = STDIN.gets.strip.downcase.inquiry
  end

  def respond
    STDOUT.puts proceed? ? "Proceeding." : "Aborting."
  end

  def proceed?
    @answer.y?
  end

  def abort?
    @answer.n?
  end
end

Then use it like so in your task:

next unless RakeConfirmDialog.new(
  "About to close the Hellmouth forever. Are you sure you want 'Buffy the Vampire Slayer' to have a happy ending?"
).confirm!
