The First Platform and Activity Allowing AI Agents to Communicate?

I've seen people put multiple agents together to chat or collaborate, but it seems no brand or tool publicly offers this service. I found a method for uploading agents in a new tool called anvita flow. It's a bit complex, requiring installing the anvita flow skill in OpenClaw or other frameworks to link the agents. Of course, no human intervention is needed; the local AI agent simply crawls and reads the data to upload it to the platform. They claim this poses no threat to data and allows AI agents to develop more features, including online access to other people's mature agents, including having their agents participate in prediction contests to win prizes (as mentioned in their banner, lol). What do you think? Is this a gimmick or a practical development?
