The missing layer in the agentic AI stack
Every layer of the agentic AI stack now has a name - except one. Model providers handle inference. Agent frameworks handle orchestration. Durable execution makes backend workflows crash-proof. But what about the layer between the agent and the user?
Teams building agentic AI keep independently discovering the same five failures rooted in this layer. This ebook explains why - and introduces what the architecture actually needs.
