Agent skill that applies Andrej Karpathy's mental models and decision heuristics, with a Chinese README
Karpathy Skill is a persona-style agent skill that answers questions through mental models distilled from Andrej Karpathy's public writing and interviews. Its README lists Hermes Agent among the runtimes that can load it.
What Karpathy Skill does
Karpathy Skill packages a thinking framework rather than a collection of quotes. According to the README, it draws on more than 20 blog posts including Software 2.0, 16 long interviews, over 100 posts on X and project READMEs, and distills them into six core mental models, eight decision heuristics and a profile of his expression style. Models named in the examples include March of Nines, build to understand, and Iron Man suit versus robot.
The skill follows the open Agent Skills format, so it runs in skills-compatible runtimes. The README names Claude Code, Codex, Cursor, OpenClaw, Hermes Agent, CodeBuddy, Gemini CLI and OpenCode among more than 50. After installing, the user asks the agent to answer from Karpathy's perspective or to switch to him. The sample dialogues and the rest of the README are in Chinese, and full example conversations sit in an examples folder. For runtimes that cannot load skills, the README suggests pasting SKILL.md into a chat.
