So far he's using Values somewhat similar to Smallville's, but with
Stylin's and Refinements which act a little like Leverage's Roles and
Specialties but are unique and perfect for the setting. He discusses
how his design decisions fit the theme and tone of the setting and
show as he goes along, which should prove very insightful for any
Cortex Plus hacker. Check it out.
