Three steps, about
four minutes.

There is no installer and no account. You clone a repo, open it in Claude Code, and run /setup once. Everything after that stays in a folder on your machine.

  1. I

    Clone the repo

    Anywhere you like — your home folder is fine. The whole system is markdown, so it is small.

    git clone https://github.com/NuminaContinuum/NuminaClaudeOS.git
  2. II

    Open it in Claude Code

    Claude Code reads the project's CLAUDE.md and loads every skill in .claude/skills/ on the way in.

    cd NuminaClaudeOS && claude
  3. III

    Run /setup

    A four-question onboarding ritual. It writes your profile.md, which every other skill reads before it speaks to you — so do this one first.

    ~/NuminaClaudeOS — claude
    ❯ /setup
    Four questions — your traditions, your language, what you are working with…
    ✓ context-library/profile.md written
    You are set up. Try /journal when you are ready.

What you need first

  • Claude Code, installed and workingNumina OS runs inside it. If you have never used it, install it first and come back.
  • A Claude subscription or an Anthropic API keyWhichever you already use with Claude Code. Numina OS adds no cost of its own.
  • Comfort with a terminal and markdown filesEverything Numina OS writes is a file you can open, edit and delete yourself.

The source lives on GitHub. It is MIT licensed, so fork it and rewrite any prompt that is not yours. If a skill feels too cold, too clinical, or wrong for your tradition, open an issue — that is the point of it being readable.
