AI agents call get_staff_member to retrieve information from Smokeball without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The severity is low because retrieving staff member data poses minimal risk—it is informational metadata that law firms typically manage with standard access controls.
