Chapter 14: Spec-Kit Plus Hands-On

Welcome to hands-on specification-driven development. This chapter transforms understanding (from Chapter 14) into practice. You won't read about specifications-you'll write them. You won't learn about AI collaboration - you'll build project with your AI companion from specifications to implementation. Chapter 14 gave you the map. Chapter 35 teaches you to drive.

🎯 Before You Begin​

What You'll Learn​

By completing this chapter, you'll master:

  1. Spec-Kit Plus Foundation - Understand WHAT Spec-Kit Plus is, WHY this book uses it, and HOW it implements SDD-RI concepts
  2. Spec-Kit Plus Architecture - Recognize Horizontal Intelligence (ADRs + PHRs) and Vertical Intelligence (orchestrator + subagents)
  3. Installation & Configuration - Install Spec-Kit Plus, configure your AI tool, initialize projects
  4. Evals-First Collaboration - How to explore problem space with AI BEFORE writing formal specifications
  5. Constitution Creation - Setting project-wide quality standards that cascade to all features
  6. Specification Writing - Creating clear, testable requirements using SMART criteria
  7. Iterative Refinement - Using /sp.clarify to identify and resolve specification gaps
  8. Architecture Planning - Generating implementation plans and documenting decisions with ADRs
  9. Task Decomposition - Breaking plans into atomic work units with checkpoint-driven execution
  10. AI-Driven Implementation - Orchestrating code generation with systematic validation protocols
  11. Reusable Intelligence Design - Transforming workflow patterns into skills and subagents that compound across projects
  12. Independent Workflow - Applying all skills end-to-end without guidance

Most importantly, you'll build the muscle memory for specification-first thinking AND intelligence accumulation that makes you dramatically faster in Chapters 32 and beyond. Let's build something real.
