I Built My Portfolio with Three Agent Protocols

Three new protocols are defining how AI agents communicate with frontends, tools, and each other: AG-UI for agent-to-user streaming, A2A for agent-to-agent coordination, and A2UI for generative UI. Instead of just explaining them, I built a live demo that uses all three.

Below, three agents collaborate to analyze your browsing context, build a visitor persona, and generate personalized portfolio recommendations - with every protocol event visible in real-time.
