The Sample Query field (optional) should contain an example of a request message formatted to be understandable by your agent. Given the sample query, a programmer should be able to construct valid request messages to send to your agent.
Ex:

(ask-one
   :ontology weather
   :content (objective :name "getInformation"
		       :parameters (listof
			            (pval "primary-keys""(ParisTX)")))
