Karpathy Retires "Vibe Coding," Willison Publishes Definitive Agentic Engineering Guide.
Story
Just one year after coining "vibe coding," Andrej Karpathy officially retires the term for "agentic engineering" — "AI does the implementation, human owns the architecture, quality, and correctness." Simon Willison simultaneously published a multi-chapter Agentic Engineering Patterns guide (497 points on HN, 283 comments) covering TDD with agents, anti-patterns, and cognitive debt prevention. Anthropic's new 2026 Agentic Coding Trends Report adds production data: agents now complete 20 autonomous actions before requiring human input (double from six months ago), Rakuten achieved 99.9% accuracy on 12.5M-line codebase modifications, and Zapier deployed 800+ internal agents with 89% adoption. This is no longer hype — it's a professional discipline with guides, courses, and production tooling. What to do: Read Willison's guide at simonwillison.net/guides/agentic-engineering-patterns/. Adopt the /simplify pre-PR workflow. Structure your CLAUDE.md for progressive disclosure. (The New Stack, Anthropic)
