An agent or operative was a trusted person employed by a public or commercial entity to perform specific tasks on its behalf. The term was often used to denote a person so engaged in intelligence or security operations.
Identifiable agents Edit
Covert operations Edit
In 2268, Nilz Baris summoned the USS Enterprise to Deep Space Station K-7 because of his fears that Klingon agents would try to sabotage the triticale stored there. Later, he criticized James T. Kirk for allowing Cyrano Jones access to the station, accusing the latter of being the agent in question, to which Kirk replied that disruption of stations was not an offense exclusive to Klingon agents. Arne Darvin was later revealed by the tribbles to be the individual they were searching for. (TOS: "The Trouble with Tribbles")
In 2371, after discovering that Seska might actually be a Cardassian agent posing as a Maquis (later confirmed to be true), the exasperated Chakotay (her former leader) told Tuvok (who, was a Starfleet agent, posing as a Maquis under Chakotay), "You were working for her. Seska was working for them. Was anyone on board that ship working for me?" (VOY: "State of Flux")
That same year, Major Kira Nerys was abducted by the Obsidian Order, surgically transformed, and told that she was actually a long-term operative named Iliana Ghemor as part of a ploy to expose the activities of Tekeny Ghemor, of Cardassian Central Command, who was suspected, correctly, of fomenting dissent.
