{"product_id":"build-your-own-ai-coding-anthony-x-9798257662386","title":"Build Your Own AI Coding Agent: Claude Code Architecture Patterns in C#","description":"You've used Claude Code, Cursor, or Copilot and wondered: how does this thing actually work? How does it read my files, decide what to do next, edit code, run tests, and fix its own mistakes - all from a single prompt?\u003cbr\u003eThis book answers that question by having you build one yourself.\u003cbr\u003eStarting from an empty directory, you create a working AI coding agent in C# and .NET that streams LLM responses in real time, calls tools to read and write your code, searches your codebase, runs shell commands, and remembers what it learned across sessions. A three-tier safety system asks permission before anything destructive happens. Multi-provider support means you can point it at Claude, GPT-4, Grok, or Gemini without changing a line of agent code.\u003cbr\u003eThe secret sauce? The agent loop - the think-act-observe cycle that turns a chatbot into something that can actually get work done. You'll build that loop in Chapter 4, and every chapter after that makes it smarter: tool calling, safety gates, project awareness, persistent memory, sub-agent orchestration.\u003cbr\u003eTwelve chapters. One AI concept and one piece of working code per chapter. Roughly 4,000 lines of clean, idiomatic C# when you're done. No machine learning background required - if you're comfortable with async\/await, interfaces, and LINQ, you have everything you need.\u003cbr\u003eThe architecture comes from real production patterns documented by the developer community through studying Claude Code's public APIs, official documentation, conference talks, and open-source reimplementations. We took those patterns - the same ones powering a tool used by hundreds of thousands of developers - and rebuilt them at a scale you can read and understand in an afternoon.\u003cbr\u003eWhat you build isn't a throwaway exercise. Want to add a new tool? Implement the interface. Want tighter safety rules? Adjust the approval gate. Want to swap LLM providers? Change one line. Your agent is yours to keep, extend, and ship.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Anthony X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798257662386\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/16\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 192\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.01lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.50w x 0.41d","brand":"Anthony X","offers":[{"title":"Paperback","offer_id":48997615010047,"sku":"9798257662386","price":29.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/build-your-own-ai-coding-anthony-x-9798257662386","provider":"WR Book House","version":"1.0","type":"link"}
