+            Event Formatting Agent allows you to format your events in any way you prefer.
+            For example if you have an event like 
+
+                {
+                  :content => {
+                    :text => "Lorem ipsum dolor sit amet"
+                            },
+                  :fields => "consectetur adipisicing elit",
+                  :data   => "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."
+                }
+
+
+            And other agents which are receiving this event, say, Twilio Agent  expects `message` key , and Digest Email Agent which expects a `subject` key, then you can reformat this event by filling `Options` in the following way.
+
+                 message => $.content.text
+                 subject => $.fields
+
+            Values must be provided in JSONPath. You can add as many keys as you like.
+
+            Then, event generated by Event Formatting Agent will be like
+
+                {
+                  :message => "Lorem ipsum dolor sit amet"
+                  :subject => "consectetur adipisicing elit"
+                }

+            }
+        end
+
+        def working?
+            true
+        end
+
+        def receive(incoming_events)
+            incoming_events.each do |event|
+                formatted_event = {}
+                options.each_pair do |key,value|
+                    formatted_event[key] = Utils.values_at event.payload,value
+                end
+                formatted_event[:agent] = Agent.find(event.agent_id).type.slice! 8..-1
+                formatted_event[:created_at] = event.created_at
+                create_event :payload => formatted_event
+            end
+        end
+    end
