Context engineering, agent skills, sub-agents, and structured planning have become the vocabulary of modern AI development. But vocabulary alone doesn't produce reliable systems. After 1,000+ hours with coding agents in production repositories at Amazon, the "vibe coding" excitement meets reality. Prompting is easy — engineering is where things break down. Effective AI-assisted development is less about generating code and more about building systems using agents as engineered components: constraining context, separating deterministic execution from LLM reasoning, and treating specs as first-class artifacts. In this session, you'll learn 5 practical rules for production-grade AI-assisted engineering you can apply immediately.
