{"product_id":"langchain-agent-engineering-lax-solace-9798187280902","title":"LangChain Agent Engineering: Build Production-Ready AI Agents, Agentic RAG, and Multi-Agent Systems with Python and LangGraph","description":"AI agents are easy to demonstrate. Engineering them to operate reliably in real-world applications is far more challenging.\u003cbr\u003eLangChain Agent Engineering is a practical guide to designing, building, testing, and deploying production-ready AI agents with Python, LangChain, and LangGraph. Rather than focusing on basic chatbot demonstrations, this book shows you how to create dependable agent systems that can use tools, manage state, retrieve trustworthy information, coordinate specialized agents, recover from failures, and operate within clearly defined security boundaries.\u003cbr\u003eYou will begin by understanding how modern AI agents work and how they differ from language models, chains, and deterministic workflows. From there, you will learn how to design reliable tools, manage conversation context, implement short-term and long-term memory, and build stateful workflows with LangGraph.\u003cbr\u003eThe book provides detailed coverage of Retrieval-Augmented Generation, including document preparation, chunking, embeddings, vector stores, retriever evaluation, query rewriting, document grading, reranking, contextual compression, corrective RAG, evidence verification, and source-aware responses.\u003cbr\u003eYou will also explore multi-agent architecture, including supervisor-and-worker systems, agent handoffs, shared state, communication patterns, and methods for preventing delegation loops and conflicting outputs.\u003cbr\u003eInside this book, you will learn how to: \u003cbr\u003eBuild tool-calling AI agents with Python and LangChain\u003cbr\u003eDesign stateful and recoverable workflows with LangGraph\u003cbr\u003eImplement short-term and long-term agent memory\u003cbr\u003eCreate agentic RAG systems grounded in external knowledge\u003cbr\u003eImprove retrieval with query rewriting, reranking, and corrective RAG\u003cbr\u003eBuild supervisor, worker, and handoff-based multi-agent systems\u003cbr\u003eAdd human approval to sensitive agent actions\u003cbr\u003eTest agents, tools, routes, state, and structured outputs\u003cbr\u003eTrace and evaluate applications with LangSmith\u003cbr\u003eDefend against prompt injection and unsafe tool execution\u003cbr\u003eControl latency, token usage, reliability, and operating costs\u003cbr\u003ePackage and prepare agent applications for production deployment\u003cbr\u003eThroughout the book, you will work with professional architecture patterns, complete Python examples, practical troubleshooting guidance, production checklists, and progressive projects. The final capstone brings the major concepts together in a production-ready agentic knowledge platform that combines retrieval, memory, orchestration, security, evaluation, and human oversight.\u003cbr\u003eWhether you are a Python developer, AI engineer, software professional, technical founder, or advanced learner, LangChain Agent Engineering will help you move beyond experimental AI demos and build agent systems that are observable, secure, maintainable, and ready for real-world use.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Lax Solace\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798187280902\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/14\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 388\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.48lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 10.00h x 7.00w x 0.80d","brand":"Lax Solace","offers":[{"title":"Paperback","offer_id":48997939773695,"sku":"9798187280902","price":24.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/langchain-agent-engineering-lax-solace-9798187280902","provider":"WR Book House","version":"1.0","type":"link"}
