AIOS

One sentence. Any complex task. Done. AIOS makes your AI coding agent actually finish the job — memory, verification, and multi-agent collaboration, all from a single instruction. Works with codex, claude, gemini, opencode, hermes, and grok.

Why AIOS

One sentence. Any complex task. Done. That's the promise.

Your AI coding agent (Codex, Claude Code, Gemini CLI, OpenCode, Hermes, Grok) is smart — but it forgets everything between sessions, can't coordinate complex multi-step work, and has no way to verify its own output. AIOS fixes all of that:

| You say | AIOS does | | —- | --- | | "Refactor the auth module" | Remembers last week's decisions, picks the right approach, makes the change, and verifies it works | | "Review this PR and update tests" | Splits the work across parallel agents, keeps coupled changes in order, collects evidence | | "Finish the release handoff overnight" | Runs the full objective with checkpoints, resumes if interrupted, delivers verified results | | "Fix the login bug" | Recalls relevant context, routes to the simplest fix path, checks the fix before showing you |

Your data stays local. Everything — memory, logs, verification — runs on your machine. Nothing leaves.

You don't change how you work. Keep using the coding client you already have. AIOS adds what it's missing.

Install in 30 seconds

macOS / Linux:

curl -fsSL https://github.com/rexleimo/aios/releases/latest/download/aios-install.sh | bash
source ~/.zshrc   # or ~/.bashrc
aios init --all
aios doctor --native --verbose

Windows PowerShell:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
irm https://github.com/rexleimo/aios/releases/latest/download/aios-install.ps1 | iex
. $PROFILE
aios init --all
aios doctor --native --verbose

Run these from a project root when you want project-level guidance and memory.

Unattended install:

node scripts/aios.mjs init --all --yes-compression-tools --yes-headroom-mcp

How it fits together

Your coding client (codex / claude / gemini / opencode / hermes / grok)
        │
        ▼
  AIOS guidance + Workflow Policy
        │
        ├── ContextDB   local project memory (pull-based)
        ├── rex-harness software control plane (Fact → Capability → Evidence)
        ├── Team / Solo long-running or parallel work
        └── Doctor / Privacy / verification evidence

rex-harness is a required planning runtime for AIOS. Release installers already bundle the pinned submodule, so a normal release install does not need a second npm package or MCP service. From source:

git clone --recurse-submodules https://github.com/rexleimo/aios.git

If the clone skipped submodules, aios init / aios setup will try git submodule update --init --recursive -- rex-harness and stop with a clear fix if recovery fails.

Rex is the default workflow for new installs. Superpowers is retired as an AIOS workflow component. See the Rex Workflow Migration guide.

Quick tour

# Initialize project marker + detected client guidance
aios init --all

# Inspect install, native client sync, safety checks
aios doctor --native --verbose

# Save and search a durable project decision
aios memo add "Keep authentication tests strict"
aios memo search "authentication"

# Parallel work or a resumable objective
aios work "Review the auth module and update its tests"
aios team 3:codex "Review the auth module and update its tests"
aios harness run --objective "Finish the release handoff" --worktree

# Preview adaptive routing without creating a live plan
node scripts/aios.mjs plan auto-gate --task "Refactor the auth module" --dry-run --json

The project marker points clients at .aios/context-db/index.json. ContextDB is pull-based: agents search or recall relevant material instead of receiving the whole history on every prompt.

Supported clients

Native or compatibility integrations for:

codex · claude · gemini · opencode · hermes · grok (Grok Build)

Feature depth varies by client. Run aios doctor --native --verbose instead of assuming every route exists everywhere.
