Simon Willison announces a new ongoing project called 'Agentic Engineering Patterns'—a structured, book-shaped collection of coding practices for professional software engineers using AI coding agents like Claude Code and OpenAI Codex. He distinguishes 'agentic engineering' (experts amplifying their skills with agents) from 'vibe coding' (non-programmers delegating entirely to LLMs). The first two chapters cover how cheap code generation changes engineering intuitions, and how test-first (red/green TDD) development improves agent output. Chapters will be published at 1–2 per week in a new 'guide' format designed for evergreen, updatable content on his blog.
