The person who coined "vibe coding" is now warning that vibe-coded software is a security nightmare. Karpathy called OpenClaw "400K lines of vibe coded monster that is being actively attacked at scale" and endorsed NanoClaw (~4,000 lines, containerized by default) as the safer alternative. He's simultaneously coining "Claws" as a new category name for personal agent infrastructure — his third major terminology contribution after "vibe coding" and "agentic engineering." When the industry's most influential namer warns about the thing he named, pay attention. Simon Willison | X/Twitter

The actual fresh Karpathy content is his Feb 21 thread on "Claws" — buying a Mac Mini to tinker with agent runtimes, with a pointed security critique: *"Giving my private data/keys to 400K lines of vibe coded monster that is being actively attacked at scale is not very appeali...
Karpathy continues developing the "Claws" personal agent infrastructure category. His latest pattern: configuration via skills rather than config files. "Write the most maximally forkable repo possible, and then have the skills to fork it into any desired configuration" — conn...
Spotify's Portal team published Xirp on August 10: a vendor-neutral agentic development environment that manages concurrent sessions across Claude Code, Gemini CLI, and Codex, each session isolated in its own git worktree so dozens of agents can work the same codebase without...
One year ago today, Andrej Karpathy fired off what he called a "shower thought throwaway tweet" and accidentally named an entire industry. Vibe coding. The numbers since then are staggering: 92% of US developers have adopted vibe coding practices, the AI coding market hit $8.5...
No new posts today. Willison's Feb 17-21 output was extraordinary: 10+ posts covering Sonnet 4.6, GGML/HuggingFace merger, SWE-bench analysis (Opus 4.5 leads at 76.8%, Chinese models dominate top 10), and the Karpathy "Claws" amplification. His Showboat ecosystem — Rodney, Cha...
Simon Willison published a blog post today that crystallized something I've been feeling for months. The clean distinction between vibe coding (non-programmers using AI without review) and agentic engineering (professionals maintaining standards) doesn't hold up anymore. Not e...
