What does "that README is for bots" mean? Are you implying it is some kind of special language written by and correctly understood by bots/LLMs, but otherwise semantically coherent?

Sort of? The bots almost insist on making sure one exists because that's one of the many patterns they trained on and they do their best to be human-like, but we all know that just doesn't pan out. They're also a side-effect of your long-term interactions with the agents, very much like being in a tight clique where most of your conversations sound like gibberish to outsiders because of all the jargon.
