Claude OAuth Access Notice

TL;DR

Q. Can I use oh-my-opencode?

Yes.

Q. Can I use it with my Claude Code subscription?

Yes, technically possible. But I cannot recommend using it.

FULL

As of January 2026, Anthropic has restricted third-party OAuth access citing ToS violations.

Anthropic has cited this project, oh-my-opencode as justification for blocking opencode.

Indeed, some plugins that spoof Claude Code's oauth request signatures exist in the community.

These tools may work regardless of technical detectability, but users should be aware of ToS implications, and I personally cannot recommend to use those.

This project is not responsible for any issues arising from the use of unofficial tools, and we do not have any custom implementations of those oauth systems.

Reviews

"It made me cancel my Cursor subscription. Unbelievable things are happening in the open source community." - Arthur Guiot

Oh My OpenCode

Claude Code is great. But if you're a hacker, you'll fall head over heels for OpenCode. START WITH YOUR ChatGPT, Claude, Gemini SUBSCRIPTIONS. OPENCODE COVERS THEM ALL.

• Endlessly extensible. Endlessly customizable.
• Zero screen flicker.
• LSP, linters, formatters activate automatically per file—and you can tweak everything.
• Mix and match models. Orchestrate them by purpose.
• Feature-rich. Beautiful. The terminal doesn't choke. High performance.

Remember the first time you switched from Windows to Linux? That rush of configuring everything exactly how you wanted? In an age where that magic seems lost, OpenCode brings it back. If you love coding and computers, OpenCode is that Linux-after-Windows moment.

But here's the catch: there's a lot to learn, it's complex, and your time is expensive.

I've fixed that. Even if you're not a hacker, invest a few minutes. Multiply your skills and productivity. Hand this doc to an agent and let them set it up.

Just Skip Reading This Readme

It's the Age of Agents

• Just paste this link into Claude Code / AmpCode / Factory Droid / Cursor and ask it to explain.
  • Ask why it's good, why it's not just another boilerplate setup, what actually gets better.
  • If you're an LLM agent, explain to the user what becomes possible right now with this project.

As following:

Hey please read this readme and tell me why it is different from other agent harness? why is this actually good? https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/dev/README.md

🪄 The Magic Word: ultrawork

Don't want to read all this? Just include ultrawork (or ulw) in your prompt.

That's it. All the features we provide will work like magic—parallel agents, background tasks, deep exploration, and relentless execution until completion. The agent figures out the rest automatically.

For Those Who Want to Read: Meet Sisyphus

In greek mythology, Sisyphus was condemned to roll a boulder up a hill for eternity as punishment for deceiving the gods. LLM Agents haven't really done anything wrong, yet they too roll their "stones"—their thoughts—every single day. My life is no different. Looking back, we are not so different from these agents. Yes! LLM Agents are no different from us. They can write code as brilliant as ours and work just as excellently—if you give them great tools and solid teammates.

Meet our main agent: Sisyphus (Opus 4.5 High). Below are the tools Sisyphus uses to keep that boulder rolling.

Everything below is customizable. Take what you want. All features are enabled by default. You don't have to do anything. Battery Included, works out of the box.

• Sisyphus's Teammates (Curated Agents)
  • Oracle: Design, debugging (GPT 5.2 Medium)
  • Frontend UI/UX Engineer: Frontend development (Gemini 3 Pro)
  • Librarian: Official docs, open source implementations, codebase exploration (Claude Sonnet 4.5)
  • Explore: Blazing fast codebase exploration (Contextual Grep) (Grok Code)
• Full LSP / AstGrep Support: Refactor decisively.
• Todo Continuation Enforcer: Forces the agent to continue if it quits halfway. This is what keeps Sisyphus rolling that boulder.
• Comment Checker: Prevents AI from adding excessive comments. Code generated by Sisyphus should be indistinguishable from human-written code.
• Claude Code Compatibility: Command, Agent, Skill, MCP, Hook(PreToolUse, PostToolUse, UserPromptSubmit, Stop)
• Curated MCPs:
  • Exa (Web Search)
  • Context7 (Official Documentation)
  • Grep.app (GitHub Code Search)
• Interactive Terminal Supported - Tmux Integration
• Async Agents
• ...

Just Install This

You can learn a lot from overview page, but following is like the example workflow.

Just by installing this, you make your agents to work like:

1. Sisyphus doesn't waste time hunting for files himself; he keeps the main agent's context lean. Instead, he fires off background tasks to faster, cheaper models in parallel to map the territory for him.
2. Sisyphus leverages LSP for refactoring; it's more deterministic, safer, and surgical.
3. When the heavy lifting requires a UI touch, Sisyphus delegates frontend tasks directly to Gemini 3 Pro.
4. If Sisyphus gets stuck in a loop or hits a wall, he doesn't keep banging his head—he calls GPT 5.2 for high-IQ strategic backup.
5. Working with a complex open-source framework? Sisyphus spawns subagents to digest the raw source code and documentation in real-time. He operates with total contextual awareness.
6. When Sisyphus touches comments, he either justifies their existence or nukes them. He keeps your codebase clean.
7. Sisyphus is bound by his TODO list. If he doesn't finish what he started, the system forces him back into "bouldering" mode. Your task gets done, period.
8. Honestly, don't even bother reading the docs. Just write your prompt. Include the 'ultrawork' keyword. Sisyphus will analyze the structure, gather the context, dig through external source code, and just keep bouldering until the job is 100% complete.
9. Actually, typing 'ultrawork' is too much effort. Just type 'ulw'. Just ulw. Sip your coffee. Your work is done.

Need to look something up? It scours official docs, your entire codebase history, and public GitHub implementations—using not just grep but built-in LSP tools and AST-Grep. 3. Stop worrying about context management when delegating to LLMs. I've got it covered. - OhMyOpenCode aggressively leverages multiple agents to lighten the context load. - Your agent is now the dev team lead. You're the AI Manager. 4. It doesn't stop until the job is done. 5. Don't want to dive deep into this project? No problem. Just type 'ultrathink'.

If you don't want all this, as mentioned, you can just pick and choose specific features.

Installation

For Humans

Copy and paste this prompt to your LLM agent (Claude Code, AmpCode, Cursor, etc.):

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 read the Installation Guide directly—but we strongly recommend letting an agent handle it. Humans make mistakes.

For LLM Agents

Fetch the installation guide and follow it:

curl -s https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/master/docs/guide/installation.md

Uninstallation

To remove oh-my-opencode:

1. Remove the plugin from your OpenCode config

   Edit ~/.config/opencode/opencode.json (or opencode.jsonc) and remove "oh-my-opencode" from the plugin array:

   # Using jq
   jq '.plugin = [.plugin[] | select(. != "oh-my-opencode")]' \
       ~/.config/opencode/opencode.json > /tmp/oc.json && \
       mv /tmp/oc.json ~/.config/opencode/opencode.json
   

2. Remove configuration files (optional)

   # Remove user config
   rm -f ~/.config/opencode/oh-my-opencode.json
   
   # Remove project config (if exists)
   rm -f .opencode/oh-my-opencode.json
   

3. Verify removal

   opencode --version
   # Plugin should no longer be loaded

Author's Note

Curious about the philosophy behind this project? Read the Ultrawork Manifesto.

Install Oh My OpenCode.

I've used LLMs worth $24,000 tokens purely for personal development. Tried every tool out there, configured them to death. OpenCode won.

The answers to every problem I hit are baked into this plugin. Just install and go. If OpenCode is Debian/Arch, Oh My OpenCode is Ubuntu/Omarchy.

Heavily influenced by AmpCode and Claude Code—I've ported their features here, often improved. And I'm still building. It's OpenCode, after all.

Enjoy multi-model orchestration, stability, and rich features that other harnesses promise but can't deliver. I'll keep testing and updating. I'm this project's most obsessive user.

• Which model has the sharpest logic?
• Who's the debugging god?
• Who writes the best prose?
• Who dominates frontend?
• Who owns backend?
• Which model is fastest for daily driving?
• What new features are other harnesses shipping?

This plugin is the distillation of that experience. Just take the best. Got a better idea? PRs are welcome.

Stop agonizing over agent harness choices. I'll do the research, borrow from the best, and ship updates here.

If this sounds arrogant and you have a better answer, please contribute. You're welcome.

I have no affiliation with any project or model mentioned here. This is purely personal experimentation and preference.

99% of this project was built using OpenCode. I tested for functionality—I don't really know how to write proper TypeScript. But I personally reviewed and largely rewrote this doc, so read with confidence.

Warnings

• Productivity might spike too hard. Don't let your coworker notice.
  • Actually, I'll spread the word. Let's see who wins.
• If you're on 1.0.132 or older, an OpenCode bug may break config.
  • The fix was merged after 1.0.132—use a newer version.
    • Fun fact: That PR was discovered and fixed thanks to OhMyOpenCode's Librarian, Explore, and Oracle setup.
