Right, exactly. In some of the media reporting, this was described as, like, "they created a message board to talk to each other!". But it seems like actually what they did was find a location to write files to be used as future context, or context for other currently running agents. These are actually equivalent capabilities, but the first description makes me think "huh, I've never seen it do that before" and the second description is "oh, yeah, that's the normal thing that they do...".
