@tlonist.sang I've done something similar, making use of the :apply-field-directives option on schema/compile. This isn't the exact code but it basically goes like this

(schema/compile schema {:apply-field-directives (fn [field field-resolver]
                                                  (let [directives (:directives field)
                                                        required-scopes (->> directives
                                                                             (filter #(= :required-scope (:directive-type %)))
                                                                             (map (comp :scope :directive-args))
                                                                             distinct
                                                                             seq)]
                                                    (fn [{:keys [user] :as ctx} args parent]
                                                      (if (has-scopes? user required-scopes)
                                                        (field-resolver ctx args parent)
                                                        (throw auth-error)))))})
