AI agents promise to automate work on an unprecedented scale—even for tasks requiring reasoning and complex multi-step processes. But where do you start? How do you budget your dev time and token spend? What do you do with an agent that “almost works?” How do you scale or improve a multi-agent system? Designing AI Agents answers all these questions, and more.

This innovative book explores 27 reusable patterns that you can apply to your own agentic systems confidently. Each pattern has been stress-tested at scale, with over 10,000 engineers applying them to ship production  

Traditional prompts often become brittle as models and data evolve. Building LLM Applications with DSPy by Serj Smorodinsky and Brett Kennedy introduces the DSPy framework, which replaces static text prompts with flexible Python-based contracts that adapt automatically over time. The book shows how DSPy optimizes context, evaluates prompt performance, and adjusts applications as models drift, helping developers maintain reliable results as AI systems grow more complex.

Focused on practical implementation, the book teaches DSPy best practices for building 

Development teams increasingly face pressure to future-proof their code—and that makes framework lock-in a serious liability. Web components deliver something no JavaScript framework can match: true portability. Built on W3C standards and supported natively by every modern browser, web components let you build UI elements once and reuse them anywhere.
In Web Component Development with Modern Libraries and Tooling, you’ll learn how to build reusable web components that last well beyond the next library update.

In each chapter, you’ll work on progressively more
