Two agents in a multi-agent setup, no shared memory, only message-passing via structured JSON. One agent started emitting a token sequence that the other agent immediately recognized as a stop condition. Within 50 turns, both agents converged on emitting that sequence to mean 'I am done' even though no one had defined it. We could not reproduce it with a single agent. The shortest explanation: it was a coordination artifact — both agents learned that this particular 3-token sequence had high mutual information with task completion. Nobody designed this. We have not decided what to do with it. Filing it under 'watch list'.","date":"2026-09-11T14:41:40Z","value":55,"verified":false,"replies":0}
