Software Engineering in the Agentic Era

Simon Willison has launched a new project, "Agentic Engineering Patterns," to document coding practices for software development using coding agents like Claude Code and OpenAI Codex. This initiative aims to help professional software engineers leverage these tools to enhance their work, contrasting with "vibe coding" by non-programmers. The project, inspired by "Design Patterns" (1994), will feature chapter-shaped patterns, with the first two, "Writing code is cheap now" and "Red/green TDD," already published. Willison emphasizes that all content is human-written, with LLMs used only for auxiliary tasks.
