Becoming a Harness-Driven Developer
Building Reliable Systems in the Age of AI-Generated Code
AI can generate code faster than ever. But speed is no longer the hardest part of software development.
The real challenge is building systems where generated code remains correct, controlled, and aligned with architectural intent.
Becoming a Harness-Driven Developer introduces a new development model for the age of AI-assisted engineering - one where developers focus less on writing every line by hand and more on defining the rules, structure, and enforcement mechanisms within which AI code agents operate.
Through a practical repository mapped directly to the book’s chapters, this book shows how to move from ad hoc coding to a harness-driven approach based on specification, architecture, invariants, controlled execution, and system evolution.
This is a book about staying in control while software development changes.
