Context Engineering: An Interactive Tutorial
Published on
In my day-to-day work I spend quite a lot of time talking to engineers about AI coding agents. And one thing that keeps coming up is context engineering — people sort of know the term, but struggle to apply it in practice.
So I built a small interactive tutorial to help with exactly that: Context Engineering.
It’s a self-paced, browser-based walkthrough that covers the foundational ideas — what context is, how the agent loop works, why context degrades over time (yes, “context rot” is a real thing), and practical techniques for keeping it focused and effective. It also touches on memory, compaction, AGENTS.md, and observability.
No setup, no installs — just open the link and go.
