Loop Engineering + 4 D's: upgraded mental model. Outer Loop = Orchestrator Inner Loop = Maker (executes the beat) 10-80-10: First 10%: Delegation + Description (you direct) 80%: Maker executes Last 10%: Checker, then Human review Key insight most people miss: The Checker must ALWAYS be a separate model. The Maker built the output. It will approve its own work every time. Separate model. No attachment. Objective gate. That's an engineered system. Not a vibe. 🔄 #AgenticAI #AIEngineering #BuildInPublic
