Oh My OpenAgent (omo, formerly oh-my-opencode) is an agent harness by code-yeongyu that turns OpenCode or the OpenAI Codex CLI into a multi-agent, multi-model coding system. It ships named orchestration agents (including Sisyphus, Prometheus, Oracle, and Librarian), a Team Mode for parallel agents, hash-anchored edits, built-in MCP servers, and loop modes (ralph-loop / ulw-loop). It comes in an Ultimate Edition for OpenCode and a Light Edition (lazycodex) for the Codex CLI. It is installed via bunx; the docs explicitly advise against global installation.
