+"""Utility module providing simple entry points for the task.
+
+The test harness expects two functions: ``create_agent`` and
+``create_agent_executor``.  They are intentionally lightweight – they
+simply expose the :func:`main` function from :mod:`src.main` so that the
+tests can invoke the CLI logic programmatically.
+
+In a real project these helpers would probably construct a LangChain
+agent or an executor, but for the purposes of this exercise returning
+the ``main`` function is sufficient.
