' It explains that while vibe coding was about fast, prompt-driven prototyping, agentic engineering is about building autonomous systems that can manage the entire software lifecycle. The author argues that developers must now learn 'agentic system design,' focusing on context management and asynchronous feedback loops.
In 2025, 'vibe coding'—the art of intuition-led prompting—was the viral trend. By early 2026, the industry has pivoted to 'agentic engineering.' This post explores why the focus has shifted from snippet generation to long-horizon optimization and tool-aware reasoning. Using the launch of GLM-5 as a case study, we look at the new infrastructure required to support agents that explore codebases strategically rather than just waiting to be prompted.
