A plugin system that orchestrates up to eleven specialized AI agents at once under Claude Code, Codex, or Cursor — each focused on its part of the task.

Oh My OpenAgent is a plugin system for AI coding agents — Claude Code, OpenAI Codex, and Cursor — that runs up to eleven specialized agents simultaneously from a single prompt. The project launched in December 2025 and reached over 69,000 GitHub stars in nine months. Author is developer code-yeongyu. Three editions: Ultimate with full capabilities (11 agents, 54+ lifecycle hooks), Light for CLI compatibility, and Senpi, a beta standalone runtime. In Team Mode all agents are visible in a split tmux terminal, each in its own pane with live status. Built-in MCP support, LSP integration, and AST-Grep let agents work with real code structure, not just raw text. This plugin system is designed around graph-based agent orchestration — each agent is a node in a task graph.

Why a vibe-coder should care

Running multiple agents in parallel directly cuts time on large tasks: one agent handles architecture while another writes tests. Visibility into all agents in one terminal removes the guesswork about what is happening at any moment. Multi-provider support lets you mix Claude Code and OpenAI Codex for different parts of the same task.

How to install

Copy this and send it to your agent — Claude Code, Codex, any of them:

Install oh-my-openagent: https://github.com/code-yeongyu/oh-my-openagent — follow the README, connect to Claude Code with the Ultimate edition, start a first parallel session and show me how to split a task across agents. Ask if you need any API keys.

Runs on a regular laptop — Node.js required.
