Dedication

To every developer who questioned whether AI would replace them, then discovered it could amplify them instead.

To the teams building AI development tools - you are not just creating software, you are redefining what it means to be a software developer.

To the early adopters who experimented, failed, learned, and shared their discoveries - and to the skeptics who protected production by finding the sharp edges first. This collective knowledge is transforming our industry.

And to the future developers who will wonder how anyone ever shipped without agents - remember that we once wondered the same about IDEs, version control, and Stack Overflow.

Every paradigm shift faces resistance. Every productivity tool eventually becomes standard. This book documents that transition.
