Part I: The Gap

A sentence to an assistant now returns an application. Whether the application is good enough for other people to rely on is a different question, and this book is about that difference. Part I describes vibe coding fairly, describes what developers do besides typing, and defines the method of twelve steps, four tiers and a takeover test.

Chapters in this part:

• Chapter 1, Introduction, states the promise and its limits and introduces the two builders.
• Chapter 2, What Vibe Coding Is, and What It Does Well, describes vibe coding and what the evidence says about it.
• Chapter 3, What Developers Do, describes the gap as twelve disciplines.
• Chapter 4, The Method, defines the twelve steps, four tiers, the takeover test and the builder's mandate.

Functions in this part. Part I frames all five developer functions and all twelve steps.

The thread from the series. The tiers, the stewardship principle and the delegation ladder are those of AI Developer, Chapters 4 and 19; the labels observable, expected and speculation are those of AI Governance, Chapter 22.

What you will learn in this part:

• What vibe coding is and what it does well
• What developers do besides writing code
• The twelve steps, four tiers and the takeover test

Part II turns to the first three steps.
