From the source SKILL.md

Use this skill when Apex code performs DML on both setup objects and non-setup objects in the same transaction. Salesforce enforces a hard runtime restriction that prevents this combination because setup object changes (permissions, roles, group membership) affect org-wide access calculations that must complete before non-setup record sharing can be evaluated. Violating this restriction throws the MIXED_DML_OPERATION runtime error.
