TrimStream/mod-the-agents ? reverse-engineered prompt

Build me a real time debate web app where a user can paste in some text, or upload an image, and four different AI personas argue over it at the same time.

I want one agent to be practical, one skeptical, one optimistic, and one to play devil’s advocate. Show their responses as they stream in, then let me jump into the middle of the debate with a short message or a suggested challenge, and have that injection change the next round. After that, the app should produce a final synthesis that pulls the whole discussion together and gives a clear verdict.

Make it feel polished and fast, with a simple modern interface. Use the Cerebras Gemma 4 model for the agents, and keep the conversation updates live without refreshing the page. If you need to look up current docs online, go for it.
