From Prompt to Agency.

How AI Agents Reason, Use Tools, Remember, and Act

By NGO TRUNG KIEN

An AI agent is not simply a chatbot with a longer prompt. It is a system that receives observations, chooses actions, calls tools, changes state, checks results and decides what to do next.

This book gives a top-to-bottom map of that system: workflows versus agents, goals, tool contracts, context, memory, planning, verification, multi-agent coordination and human authority, with every concept turned into an artifact and a test.

Publisher-adapted draft; audience scope awaits expert review.
