If the skill is required in order to route work to an individual or workbasket then the required checkbox must be checked otherwise it is considered a desired skill.

The two standard properties Assign-.pxSkillsDesired and Assign-.pxSkillsRequired can each hold an array of skill names relevant to an assignment. Standard functions in the Pega-ProCom Routing library use the values in these two properties to determine which operators are eligible, based on skills and proficiency, to receive an assignment.

To support efficient operation of routing activities, instances of the Index-OperatorSkills class support direct access to operators holding a specific skill. Review the standard Work-.ToSkilledGroup activity for an example routing activity that uses this index. 

You can find some additional information about routing from this previous post:  https://pdn.pega.com/forums/prpc/case-management-and-process/skill-based-routing
