Introduction
“Prompting is easy. Getting reliable behavior from an AI system is hard.”
If you’ve ever built or worked anything serious with LLMs, you’ve already discovered the truth:
hallucinations, drifting answers, and inconsistent behavior are not bugs — they are symptoms of bad context.
Here’s a number that should change how you think about this: developers in 2026 can fully delegate only 0–20% of tasks to AI agents — even though those agents are completing an average of 20 autonomous actions per run. The bottleneck isn’t model intelligence. It’s context quality.
In 2026, the most important AI skill for developers is no longer prompt engineering.
It is context engineering.
This post explains what that really means, and how developers can build AI systems that are predictable, grounded, and production-grade.
