Building AI Agents from Scratch: Designing and Implementing LLM-Powered Agent Systems
Co-authored by Yuhang Yao and Bosheng Ding, this book presents a systematic path from the foundations of intelligent agents to the engineering of production-ready, large-language-model-powered agent systems.
It develops a six-layer view of agent architecture and covers task planning, tool use, model routing, memory management, multimodal input, multi-agent collaboration, and safety and compliance. The emphasis is on durable design principles as well as reproducible implementation.
Hands-on case studies span RAG-based customer service, multimodal content creation, coding automation, personalized education, LangGraph-based game characters, financial decision-making and trading, healthcare, and legal services. Published by Electronic Industry Press in January 2026; 160 pages.
