Context engineering is evolving beyond managing context windows to building complete AI systems with problem decomposition and complex control flows.
Modern AI tools like Claude Code and Anthropic's AI pair programming system involve complete systems, not just prompts or context, which coordinate tasks intelligently.
Building efficient AI systems requires recognizing the importance of decomposing problems, comprehensive evaluation strategies, and continuous improvement in various aspects.
The evolution in AI engineering signifies a shift towards building intelligent applications that require a new level of software engineering expertise, leading to the development of sophisticated AI-native applications.
