Architecting Agentic AI Fundamentals & Core Patterns: A Comprehensive Hands-On Guide to Agentic AI Frameworks, Multi-Agent Reasoning, and Scalable Aut (Hardcover) (ISBN-13: 9798906040329)

Volume 1 of The Agentic AI Handbook. As the industry shifts from reactive prompts to goal-seeking autonomous systems, software architects, AI engineers, and technical leaders need a rigorous foundation in agentic design. This volume explores the anatomy of an agent and the complete lifecycle from sensing and planning to acting and reflecting. Readers will discover exactly why agentic AI is necessary now, how to evaluate the 2026 landscape of reasoning models, and when to deploy agents versus classic machine learning approaches. Moving beyond basic models, this book details the fundamental patterns required to build robust systems. You will learn to design single-task chains, instruction trees, and tree-of-thought workflows while implementing critical safety guardrails and human-in-the-loop controls. The text provides deep dives into tool invocation, function calling, and API integration, emphasizing transactional safety, retries, and rollback mechanisms. It also tackles the complexities of long-horizon task continuity, breaking down the differences between episodic and semantic memory, profile stores, and checkpointing strategies. Finally, the volume addresses the critical challenge of context engineering and retrieval. Engineers will master the tradeoffs between long-context models and retrieval systems, exploring RAG, GraphRAG, and hybrid approaches. By mastering vector stores, context compression, and prompt caching, you will be equipped to architect self-repairing, highly grounded agentic systems.
