Oh My OpenCode
OpenCode plugin that turns it into a full multi-agent development harness. Background agents, specialized teammates (Oracle, Librarian, Frontend Engineer), LSP/AST refactoring, curated MCPs, and a Claude Code compatibility layer.

The Magic Word: ultrawork
Just include ultrawork (or ulw) in your prompt — all features activate automatically: parallel agents, background tasks, deep exploration, relentless execution. The agent figures out the rest.
Sisyphus & Team
Main agent is Sisyphus (Opus 4.5 High). His teammates:
| Agent | Role | Model |
|---|---|---|
| Oracle | Design, debugging, high-IQ backup | GPT 5.2 Medium |
| Frontend UI/UX | Frontend development | Gemini 3 Pro |
| Librarian | Official docs, open source, codebase exploration | Claude Sonnet 4.5 |
| Explore | Blazing fast codebase grep | Grok Code |
| Prometheus | Planner | Configurable |
| Metis | Plan consultant | Configurable |
| Multimodal Looker | Vision/image analysis | Configurable |

Installation
Copy to your LLM agent (Claude Code, AmpCode, Cursor, OpenCode):
Install and configure oh-my-opencode by following the instructions here:
https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/master/docs/guide/installation.md
Or let an agent handle it — the project strongly recommends agent-driven setup.
Configuration
Configure via .opencode/oh-my-opencode.json (project) or ~/.config/opencode/oh-my-opencode.json (user). JSONC format (comments + trailing commas supported). All features customizable — override models, temperatures, prompts, permissions, concurrency limits, categories, and more.
Reviews
“It made me cancel my Cursor subscription. Unbelievable things are happening in the open source community.” — Arthur Guiot
“If Claude Code does in 7 days what a human does in 3 months, Sisyphus does it in 1 hour.” — B, Quant Researcher
“Knocked out 8000 eslint warnings with Oh My Opencode, just in a day” — Jacob Ferrari
“I converted a 45k line tauri app into a SaaS web app overnight using Ohmyopencode” — James Hargis
“Oh My OpenCode Is Actually Insane” — Darren Builds AI (YouTube)
Claude OAuth Notice
As of January 2026, Anthropic restricted third-party OAuth access citing ToS violations. The project was cited as justification for blocking opencode. Using it with Claude Code subscription is technically possible but the author cannot recommend it. The project has no custom OAuth implementations.
Philosophy
Inspired by AmpCode and Claude Code — features ported and often improved. The author describes it as “Ubuntu to OpenCode’s Debian/Arch.” If you love coding and computers, OpenCode is described as “that Linux-after-Windows moment.”
