CROSS-CATEGORY: Agent Infrastructure Wars Erupt — Google (Antigravity SDK + WebMCP), CopilotKit (AG-UI), and Camunda (ProcessOS) All Ship Agent Platforms in Same 2-Week Window

Three distinct layers of agent infrastructure shipped simultaneously in May 2026: Google's Antigravity SDK + WebMCP (agent runtime + browser tool standard), CopilotKit's AG-UI (agent-to-UI protocol adopted by Google/Microsoft/Amazon/Oracle), and Camunda's ProcessOS (agent-driven business process automation). This is the infrastructure layer race for the agentic era — the equivalent of the cloud platform wars (AWS/Azure/GCP) but for AI agents. The convergence on open standards (WebMCP, AG-UI, MCP) signals that agent interoperability, not model capability, is becoming the competitive battleground.
