A simpler way to understand where agentic architecture is goingThe current generation of agentic systems is already solving several difficult problems.Agents can call tools through the Model Context Protocol (MCP). They can communicate with other agents through the Agent2Agent Protocol (A2A). They can execute isolated workloads through sandboxes and increasingly portable WebAssembly components. They can propagate distributed traces, authenticate remote identities, and apply policies before or after tool execution.These are important advances.But there is a gap between all of these mechanisms.They tell us how agents communicate, how they discover capabilities, how they call tools, and how software is executed.They do not yet provide a sufficiently strong common semantic model for answering a more fundamental question:«What exactly is the thing being executed?»This article introduces that problem in a deliberately simple way before defining the technical foundations of a more formal arch...
