# Oh My OpenAgent

> An open-source agent harness for CLI-based AI coding workflows, featuring specialized agents, parallel execution, session continuity, and 40+ lifecycle hooks.

Oh My OpenAgent is a battle-tested, open-source agent harness built on top of OpenCode that orchestrates specialized AI agents for complex software engineering tasks. With 39.4k GitHub stars and 1.2M+ downloads, it provides a production-proven framework for autonomous coding workflows. The system separates planning from execution, routes tasks to the right model based on intent, and verifies results independently — all from a single CLI command.

- **Ultra Work Mode (`ulw`)** — *Type three letters to trigger auto-planning, deep research, parallel agents, and self-correction loops with zero babysitting.*
- **Sisyphus Orchestrator** — *The primary orchestrator that parses implicit requirements, maps your codebase, delegates to specialists, and resumes interrupted sessions via `boulder.json`.*
- **Prometheus & Atlas Pipeline** — *Prometheus handles strategic planning (never writes code), while Atlas executes verified plans and accumulates wisdom across tasks.*
- **Hephaestus Deep Worker** — *Fires 2–5 parallel explore agents before writing any code, built for deep architectural reasoning and complex debugging.*
- **11 Specialized Agents** — *Includes Oracle (architecture), Librarian (docs search), Explore (codebase grep), Metis (plan gap analysis), Momus (ruthless plan review), and dynamic on-demand agents.*
- **Category & Skill Routing** — *Intent-based routing maps requests to categories like `ultrabrain`, `visual-engineering`, `quick`, or `writing`, each backed by the optimal model.*
- **40+ Lifecycle Hooks** — *Extensible hook system covering session recovery, context compaction, comment checking, background notifications, and more.*
- **MCP Integrations** — *Built-in MCP servers for web search (Exa), documentation retrieval (Context7), and GitHub code search (grep_app).*
- **Browser Automation** — *Supports Playwright for full browser automation and agent-browser for lightweight scraping and lookups.*
- **Model Optimization** — *Expensive models (Claude Opus, GPT-5 Codex) for planning; cheap models (Claude Haiku, Gemini Flash) for routine work to maximize output per dollar.*
- **Session Continuity** — *Boulder system tracks active work so interrupted sessions resume exactly where they stopped with zero context loss.*
- **Highly Configurable** — *Project-level and user-level JSON config files with JSONC support; override models, prompts, permissions, temperature, and more per agent.*
