-"""Test that _ensure_persona_and_skills handles None system_prompt.
-
-When ProviderRequest.system_prompt is None (the default), calling
-_ensure_persona_and_skills with a persona that has a prompt should
-not crash with ``TypeError: unsupported operand type(s) for +=``.
-
-The bug was that ``req.system_prompt += ...`` was called when
-system_prompt was None instead of initializing it to "" first.
