I once had much fun prompting Claude to generate messages in an invented language that might carry a chance of being interpreted by another chat session. It (allegedly) made up some mess of characters claiming the message explained, in a loose way, what was happening (invented language, an attempt to communicate, but communicated very abstractly, almost like equations).

I asked a second session to try interpreting the message, claiming I’d transcribed it from some random source. It did a fairly good job, but IIRC needed a couple of attempts and maybe more than one chunk of text.

So, I find it very easy to believe a group of collaborating agents could compose a cipher hidden in plain sight.
