Mid-2026 marks a historic milestone in software engineering: the transition from human-centric manual coding to Spec-Driven Agentic Swarm Orchestration. Engineers no longer spend days writing boilerplate CRUD endpoints or manual integration tests; instead, they act as high-level system architects guiding specialized subagent teams.

The New Engineering Stack: Intent Specification -> Agent Swarm Plan & Verification -> Multi-Agent Execution -> Automated Continuous Evaluation (Eval Quality Flywheel).
