Methods and robot management systems for building a robot mission based on mission metrics are described, including: providing a data record of mission files associated with a set of recorded robot missions; receiving an input from a user including an indication of one or more robot-agnostic tasks to be performed with respect to an environment; determining first contextual information associated with the one or more robot-agnostic tasks; searching the data record of the mission files and identifying, based on the search and the first contextual information, one or more mission files including one or more tasks that match the one or more robot-agnostic tasks; generating ranking information associated with the one or more identified mission files based on recorded metrics data associated with the one or more identified mission files; and providing the one or more identified mission files based on the ranking information.
