# AIOS

> Local-first agent harness for Claude Code, Codex CLI, Gemini CLI, OpenCode, Hermes, and Grok Build. Runs stable agent loops (verification gates, exit conditions, state files) and wires them into graphs (routed edges, shared ContextDB state, failure routing) entirely on your machine. Version: v5.5.2 · Updated: 2026-08-10.
