oh-my-openagent

Oh My OpenAgent (OMO) is an enhancement layer for coding agents like Claude Code, OpenCode, and Cursor. Instead of one agent doing everything, it splits work across specialized sub-agents, a planner, a builder, an orchestrator, that run in parallel and hand off to each other. One command turns the whole crew loose on a task until it's done. It's free to use, but the license is the Sustainable Use License, which limits you to internal business or non-commercial use. That is not open source.

The pitch is that orchestrating several models beats betting on one. It adds parallel team mode with tmux panes so you can watch agents work, content-anchored edits to avoid stale-line mistakes, and built-in web search and docs lookup. Setup is light: it's config files dropped into your project, not a service to run.

It works best if you already live in an agent harness and want more horsepower. Solo developers and small teams get the most out of it. Larger teams should test it on throwaway work first, because autonomous multi-agent runs can rack up API spend and make sweeping changes fast.

The catch: this is young, opinionated software under a custom license, not a battle-tested standard. The marketing leans hard on grand claims. Treat it as a promising experiment, not infrastructure, and read what it's doing before you let it run unattended on code you care about.
