In its own words

Aboutalirezarezvani/gaios

Fork it for any role or domain.

README.md

Clone it, run /setup, and it becomes yours in Claude Code or Codex — a second brain + Chief of Staff that holds your context, structures your work, drafts in your voice, and runs reliable workflows.

Open-source and opinionated — complete out of the box, not a blank slate. Fork it and make it yours for any role, company, or domain.

Quick start

  • Clone this folder to your machine.
  • Open it in Claude Code or Codex and run **/setup** (in Codex: invoke the setup skill or just ask it to "run setup").
  • Answer the guided interview (identity, voice, priorities, stack, team, guardrails). It fills CLAUDE.md, context/, references/voice.md, and connections.md.
  • Try the first prompt: "what should I focus on this week?"

Not sure what to write? Skim examples/ first — directional guides by role (founder, ops, regulated medtech, creator, sales) that show the shape of a filled gAIOS. They're direction, not data — you won't copy them.

Runtime compatibility (Claude Code · Codex · others) is summarized in Compatibility below.

What's inside (the architecture)

The Four Cs — Context (knows your business) · Connections (reaches your stuff) · Capabilities (knows how to do the work) · Cadence (runs without being asked).

The Three Ms — Mindset · Method · Machine (references/3ms-framework.md). *Both frameworks inspired by Nate Herk's work — see NOTICE.*
