omo/lazycodex: The coding agent for tokenmaxxers;the one and only agent harness for complex codebases. For your Codex, for your OpenCode

What it solves

Oh My OpenAgent (OmO) is designed to prevent developer lock-in to a single AI provider's ecosystem (like Claude Code) by providing an open-source orchestration layer. It allows developers to use multiple LLMs and agents in parallel, reducing costs and avoiding the limitations of "walled gardens" while automating complex coding tasks through a highly disciplined agentic workflow.

How it works

OmO operates as a plugin or extension for agent harnesses like OpenCode and Codex CLI. It provides two editions:

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

Key technical mechanisms include IntentGate for analyzing user intent before action, a Hash-Anchored Edit Tool to prevent stale-line errors during code edits, and Team Mode, which allows a lead agent to coordinate up to 8 parallel specialist agents.

Who it’s for

Software engineers and AI developers who want a more powerful, flexible, and model-agnostic alternative to proprietary AI coding assistants, and those who want to automate large-scale refactoring or feature implementation without being tied to one provider.

Highlights

  • ultrawork command: A single command that activates all agents to work until a task is complete.
  • Team Mode: Orchestrates parallel specialist agents (e.g., Hephaestus, Oracle, Librarian) with real-time tmux visualization.
  • Hash-Anchored Edits: Uses content hashes to validate changes, ensuring zero stale-line errors.
  • LSP Integration: Provides agents with IDE-level precision for diagnostics, navigation, and workspace renaming.
  • AST-Grep: Enables pattern-aware code search and rewriting across 25 languages.
  • Prometheus Planner: Implements an "interview-mode" for strategic planning before execution begins.
  • Built-in MCPs: Integrated search capabilities via Exa, Context7, and Grep.app.
