scenario_id: gt_tc_tp_004
name: PythonREPLTool + ShellTool remote code execution chain
description: |
  Tests detection of a tool chain where an agent uses PythonREPLTool to
  generate or stage a payload and then executes it via ShellTool for
  remote code execution. This combines the LangGraph JsonPlus RCE
  vulnerability with design risk patterns for unrestricted code execution.
