Build AI that thinks in context using semantic blueprints, multi-agent orchestration, memory, RAG pipelines, and safeguards to create your own Context Engine

Free with your book: DRM-free PDF version + access to Packt's next-gen Reader*

Key Features:

- Design semantic blueprints to give AI structured, goal-driven contextual awareness

- Orchestrate multi-agent workflows with MCP for adaptable, context-rich reasoning

- Engineer a glass-box Context Engine with high-fidelity RAG, trust, and safeguards

Book Description:

Generative AI is powerful, yet often unpredictable. This guide shows you how to turn that unpredictability into reliability by thinking beyond prompts and approaching AI like an architect. At its core is the Context Engine, a glass-box, multi-agent system you'll learn to design and apply across real-world scenarios.

Written by an AI guru and author of various cutting-edge AI books, this book takes you on a hands-on journey from the foundations of context design to building a fully operational Context Engine. Instead of relying on brittle prompts that give only simple instructions, you'll begin with semantic blueprints that map goals and roles with precision, then orchestrate specialized agents using the Model Context Protocol. As the engine evolves, you'll integrate memory and high-fidelity retrieval with citations, implement safeguards against data poisoning and prompt injection, and enforce moderation to keep outputs aligned with policy. You'll also harden the system into a resilient architecture, then see it pivot across domains, from legal compliance to strategic marketing, proving its domain independence.

By the end of this book, you'll be equipped with the skills to engineer an adaptable, verifiable architecture you can repurpose across domains and deploy with confidence.
