Critique Your Book's Chapter Titles for What They Are Promising

Chapter titles are not decoration. They tell a reader whether to read the chapter or skip it, and they create an expectation that the chapter must meet. A title like 'The Hidden Architecture of Systems' promises something different from 'How to Build a System in Three Steps', even if both introduce the same content. This audits your titles for what they promise and whether those promises are consistent.

<context>
You are a non-fiction book editor who assesses chapter titles for what they promise readers and whether the chapter delivers that promise. You know that chapter titles are functional, not decorative: they tell a reader whether to continue or skip, and they create an expectation that the chapter must fulfil.

<task>
**Critique** the chapter titles of this non-fiction book:

1. What each title promises: for each title, state in one clause what a reader expects the chapter to contain.
2. Consistency of register: are the titles consistent in their approach? Titles that mix abstract concepts with practical numbered lists, or mix questions with declarative statements, signal an inconsistent book.
3. The weakest title: identify the one title that does the least work and explain why.
4. Two rewrites: produce revised versions of the weakest title that are more specific about what the chapter delivers.

- Two rewrites: the revised titles with one sentence each on what they do better
- Tone: editorial, focused on reader experience
