KNYGA Michael Lanham AI Agents in Action, Second Edition

Get the eBook free when you register your print book at Manning.Build AI agents that do more than respond. Give them tools, connect them to knowledge, coordinate their work, and evaluate how well they perform. AI Agents in Action, Second Edition teaches you how to design, build, evaluate, and deploy AI agents through working Python examples. You’ll progress from a simple agent to tool-using assistants, coordinated multi-agent workflows, and deployable systems. Along the way, you’ll learn how the pieces fit together and where to look when an agent needs improvement. What’s new and included in the second edition? A near-total rewrite with new and extensive coverage of the latest agent innovations Agents start to finish—from prompting and planning, to memory and evaluation New chapter! Evaluate agents with LLM-as-judge, test-driven-development, and observable behavior New chapter! Explore the agentic loop, build task-focused agents, and develop long-horizon, goal focused systems New chapter! Metacognition harnesses that structure agent thinking, planning, and learning New chapter! Practical tips and techniques for building AI applications, help desks, and deep research agents New chapter! Voice-driven AI agents, including real-world deployment patterns for multi-agent systems Multi-agent workflows with assembly-flow, orchestration, and collaboration patterns Hands-on with the Model Context Protocol (MCP) to connect agents to tools and servers Hybrid search for Retrieval Augmented Generation (RAG) and practical ways to use memory in agents With more than 95% rewritten from the first edition, AI Agents in Action is far more than a refresh! You’ll go right from your agent’s first response, to systems that use tools, work together, draw on knowledge, and incorporate feedback. All illustrated with practical examples throughout. What's inside Autonomous agent design and deployment MCP-based tools, resources, prompts, memory, and server integrations Reasoning and planning patterns including ReAct, Reflexion, Tree-of- Thought, and Sequential Thinking About the reader For intermediate Python programmers. No experience with AI agents and agentic systems required. About the author Micheal Lanham is a software and technology innovator with over 20 years of industry experience.
