+    Executes the `Garak <https://github.com/NVIDIA/garak>`_ adversarial probe suite
+    against a local or remote LLM proxy. The module writes a Garak REST config,
+    launches the ``python -m garak`` subprocess, and streams results into the
+    shared :data:`tools_inbox`` queue.
+
+    The module requires ``garak`` to be installed (``pip install garak``) and
+    an LLM proxy running at the address configured via the ``port`` option
+    (default: ``8718``).
