Fragments: April 29

This article by Martin Fowler, part of his 'Fragments' series, covers Chris Parsons' updated guide on using AI for software development. It highlights the shift from vibe coding to agentic engineering, where verification is key. Fowler emphasizes that the game is now about how fast teams can verify correctness, not just build. He discusses the role of tools like Claude Code and Codex CLI, and the importance of building better review surfaces and automated gates. The article also references Birgitta Böckeler's work on harness engineering, focusing on computational sensors like static analysis and tests. It provides insights for senior engineers on adapting to AI-driven workflows.
