Agentic Engineering: The Complete Practical Guide

Coding with AI agents is easy to demo and hard to do well. This book is about doing it well. Agentic Engineering: The Complete Practical Guide lays out a repeatable discipline for building real software with AI agents — not vibe-coding your way to a prototype, but shipping systems you can maintain.

At its core are three practices you'll use on every project: a six-stage SOP (Spec, Plan, and the stages that carry work from idea to shipped feature), a three-layer documentation model that keeps humans and agents aligned, and an agent division of labour that assigns the right work to the right agent. The book builds these up from foundations, then runs a real project end to end so you see the whole loop in practice — including validation, rollback, and honest retrospectives.

The later parts tackle what it takes to scale: running agents on real codebases, keeping quality high, and where the discipline is heading. It closes with copy-ready templates, a six-stage SOP checklist, a glossary, and further reading.

You will learn to: - Move from ad-hoc "vibe coding" to a repeatable agentic engineering process - Run the six-stage SOP from spec to shipped feature - Structure three-layer documentation that keeps agents on track - Divide work across agents deliberately - Validate, roll back, and retrospect like a real engineering team - Scale agentic development on real software
