BuiltWith connects to a Nagent workspace with an API key. Once it is connected, agents can call 11 BuiltWith actions, such as "Create Domain List File", "Datasets Lookup" and "Domain API Lookup". Nothing is enabled on connect: each action is allowed one at a time, and an action with side effects runs or waits for a person according to the agent's level.
