oh-my-openagent: an AI agent orchestration layer that transforms coding assistants into a parallel development team

What it solves

Oh My OpenAgent (OmO) solves the complexity of managing multiple AI coding agents and workflows. Instead of manually configuring separate tools like Claude Code or Codex, OmO provides a unified orchestration layer that allows users to deploy a full AI development team in parallel, reducing the time spent on setup and manual debugging of agents.

How it works

OmO operates as a plugin or extension for agent harnesses (primarily OpenCode and Codex CLI). It offers two editions:

• Ultimate Edition: A full-featured orchestration layer for OpenCode, featuring 11 agents, 54+ lifecycle hooks, and built-in MCPs (Model Context Protocol) for web, documentation, and code search.
• Light Edition: A portable set of components (rules, LSP, git-bash) that integrate directly into the OpenAI Codex CLI plugin system.

Key mechanisms include ultrawork (a single command to activate all agents), Team Mode for parallel execution with a lead agent and up to 8 members, and a Hash-Anchored Edit Tool to prevent stale-line errors during code modifications.
