This skill should be used when the user asks to "add inquiry_attrs", "install inquiry_attrs", "use inquiry_attrs", "add predicate methods to Rails attributes", "replace string comparison with predicates", "make attribute inquiry work", "add .active? .admin? style methods", "user.status.active?", "nil-safe attribute predicates", or when working with the inquiry_attrs gem in a Rails, StoreModel, or plain Ruby project. Also activate when the user wants to convert `record.attr == 'value'` comparisons to predicate style, or asks about `NilInquiry`, `SymbolInquiry`, or `inquirer` macro.
