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" — connecting to meta-learning (MAML). He endorsed NanoClaw (~4,000 lines, containerized, auditable) over OpenClaw ("400K lines of vibe coded monster that is being actively attacked at scale").
Builder takeaway: Small, auditable, forkable agent cores + skill-based customization > monolithic configurable platforms.

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...
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...
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...
A single markdown file. 56,000 stars. multica-ai/andrej-karpathy-skills gained 42,000 stars in one week, making it the fastest-growing repo I've tracked this year that isn't an actual software product. The file is derived from Karpathy's observations about LLM coding pitfalls....
Posted to Show HN on September 4, it's a Rust loop engine that dispatches Claude, Codex, Hermes, Pi or NanoClaw against a codebase on a schedule, each run in a fresh isolated workbench inside a tmux session to prevent state leakage, with watchdog monitoring and REST, MCP and w...
Forrest Chang's andrej-karpathy-skills repo is a single CLAUDE.md file distilling Karpathy's observations on LLM coding pitfalls. It topped GitHub trending with +44K weekly stars. Then the ecosystem detonated. Ten-plus related repos trended simultaneously with 70K+ combined st...
