Objective

Implement a Spec-Driven Development Pipeline that automates the software development lifecycle from issue creation through deployment, using 5 specialized AI agents coordinated by GitLab CI/CD and the Spec-Kit methodology.


Key Components:

  • Claude Code CLI with 5 specialized agents (PM, Architect, Security, Developer, QA)
  • GitLab CI/CD pipeline with 11 stages
  • Spec-Kit methodology for structured specifications
  • Kanban board with scoped labels for visibility

Five-Layer Architecture
