I’m Luhui Dev, a developer who has been breaking down Agent engineering and exploring how AI can be applied in education.
I focus on Agent Harness, LLM application engineering, AI for Math, and the productization of education SaaS.
Intro
Agent demos are easy to get excited about. A model, a few tools, a prompt, wrap it in a loop, and suddenly you have something that searches, writes files, and calls APIs.
But between a demo and a production system, there's a long gulf. I call it the Runtime gap — and what crosses it isn't a smarter model. It's a runtime that can hold up complex, unstable, interruptible, recoverable workloads in a real environment.
