Pre-Reading Briefing - **Core Question**: How can software stay easy to change as it grows, without making a small change hard to locate or risky to make? - **Key Points to Watch For**: - What the author's “F12 test” measures when navigating an unfamiliar codebase. - How the two project stories show different ways the cost of change can rise. - Which measure the author uses to judge an architecture, beyond its apparent simplicity. - How the author moves from those experiences to the proposed four-piece structure; what evidence would make that proposal convincing? - Why locating a rule may matter more when code can be generated quickly. - **Context & Thread from Prior Chapters**: This is the first chapter. In *Context Engineering*, the reader is currently examining the claim that information available to a model shapes its output. Watch for whether code organization affects what a human or model can find; keep the question open while reading. --- ## 2. Reading Review & Reflections - **Status**: Awaiting reader completion and active-recall responses. --- ## 3. Chapter Synthesis - **Status**: Pending post-reading discussion.
