The original title is "How AI shifts software engineering value toward specifications and architecture"

Short summary

AI made writing code nearly free, shifting engineering value toward specifications, architecture, and decision-making. The author proposes Spec Driven Development (features start with specs, not chat conversations) and FOCUS Architecture (View, Orchestrator, Use Cases, Repository) to reduce ambiguity, token waste, and rework. Both books synthesize established engineering principles for the AI era.

• •AI shifted engineering value from code production to specifications and architecture
• •Spec Driven Development replaces chat-based coding with spec-first workflows
• •FOCUS Architecture organizes code into four layers to reduce context and token costs

Generated with AI, which can make mistakes.
