Sub-Agents with Claude

As AI systems evolve, developers are no longer limited to working with a single, general-purpose assistant. With Claude, it is possible to design sub-agents, specialized AI units that can take on focused tasks, operate independently, and collaborate as part of larger workflows. This book is a hands-on guide for Python developers who want to move past simple prompts and start engineering real agentic systems with Claude.
You will learn how to integrate the Claude API into your projects, create targeted sub-agents that handle narrow responsibilities, and orchestrate them into reliable pipelines. Along the way, you'll explore practical techniques for prompt design, context management, and secure execution so your agents remain both effective and safe. Real coding examples and walkthroughs show you how sub-agents can implement features, refactor code, review pull requests, write tests, and automate repetitive developer tasks.
Rather than offering abstract theory, this book stays grounded in practice. Each chapter builds on concrete use cases, showing you how to expand Claude from a single assistant into a structured team of specialized AIs. By the end, you will understand how to design, deploy, and manage sub-agents that work as genuine coder helping you write cleaner code, ship faster, and push your projects further than before.
