Specification-Driven Development

Large Language Models (LLMs) are changing how we write software. Their ability to generate code at incredible speeds is a game-changer, but this power comes with a critical challenge: unpredictability. Because LLMs are probabilistic by nature, we can't always guarantee their output is reliable or correct. The solution

The Context Layer: Why It’s the Missing Architecture Pattern in AI Systems

Defining the Context Layer The context layer is the architectural component responsible for acquiring, organizing, maintaining, and delivering relevant information to AI systems at the appropriate time and granularity. Just as we have data layers that abstract database complexity and service layers that encapsulate business logic, the context layer manages
