剧中一共出现了7个协议，如下：
1： The mission comes first. 任务优先。
2： Never jeopardize your cover. 不要暴露身份。
3： Don't take a life; don't save a life, unless otherwise directed. Do not interfere. 除非另有指示，否则不要杀人，不要救人。不要干预。
4： Do not reproduce. 不要繁衍后代。
5： In the absence of direction, maintain your host's life. 没有任务时，维持宿主的既有生活。
6： Do not communicate with other known travelers outside of your team unless sanctioned by the Director. 除非Director批准，否则不能联系小组以外的穿越者。
Omega ： the Director is no longer intervening in this timeline as either the Traveler program succeeded in its mission or it has totally failed. Director不再介入此时间线：意味着穿越者计划已经成功或完全失败。
