Architecting Agentic AI Applications: The Complete Engineering Guide

Introduction There is a gap most engineering teams discover too late. The prototype works . The demo impressed stakeholders . Someone asks, "When can we get this to production?" and the room goes quiet. Because everyone who built the thing knows the uncomfortable truth: what they demonstrated was a controlled proof of concept, not a production ready system. Agentic AI is unlike any system most engineers have built before. It reasons . It loops . It takes real world actions . It fails in non dete
