Install the Andrej Karpathy Skills skill

A community skill: it installs from its own repository and your agent runs the project's instructions locally with your own model. SkillGild lists it and credits the author; nothing runs on SkillGild.

  1. With the SkillGild CLI (needs git). It clones multica-ai/andrej-karpathy-skills and copies the skill folder into the right place for your agent; use --agent codex, cursor or gemini-cli for other clients.

    Terminal
    skillgild install karpathy-guidelines --agent claude-code
  2. Claude Code plugin marketplace.

    Terminal
    /plugin marketplace add forrestchang/andrej-karpathy-skills
    /plugin install andrej-karpathy-skills@karpathy-skills
  3. Any agent, with the skills CLI.

    Terminal
    npx skills add multica-ai/andrej-karpathy-skills
  4. Manual copy.

    Terminal
    curl -o CLAUDE.md https://raw.githubusercontent.com/forrestchang/andrej-karpathy-skills/main/CLAUDE.md
  5. Or copy the folder yourself from multica-ai/andrej-karpathy-skills (folder skills/karpathy-guidelines) into ~/.claude/skills/karpathy-guidelines/ for Claude Code, ~/.agents/skills/ for Codex, ~/.cursor/skills/ for Cursor or ~/.gemini/skills/ for Gemini CLI, then start a new session.
