defmodule Mix.Tasks.Run.Live do

  @shortdoc "Runs Elixir scripts with live Claude API calls"
  @moduledoc """
  Runs Elixir scripts against the live Claude API instead of using mocks.

  This task temporarily disables mocking and runs the specified script with actual API calls.
  Use with caution as it will make real API calls and incur costs.

  ## Usage

      mix run.live script.exs
      mix run.live examples/basic_example.exs
      mix run.live examples/simple_analyzer.exs path/to/file.txt

  ## Examples

      # Run a simple analysis script
      mix run.live examples/simple_analyzer.exs lib/claude_agent_sdk.ex
      
      # Run any custom script with live API
      mix run.live my_script.exs

  ## Options

  All additional arguments are passed through to the script.
