Anthropic blocked OpenCode because of us. Yes this is true. They want you locked in. Claude Code's a nice prison, but it's still a prison.

We don't do lock-in here. We ride every model. Claude / Kimi / GLM for orchestration. GPT for reasoning. Minimax for speed. Gemini for creativity. The future isn't picking one winner—it's orchestrating them all. Models get cheaper every month. Smarter every month. No single provider will dominate. We're building for that open market, not their walled gardens.

"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. It just works until the task is done. It is a discipline agent."
- 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 and ralph loop. Started with interview me prompt, asked it for ratings and recommendations on the questions. It was amazing to watch it work and to wake up this morning to a mostly working website!" - James Hargis

"use oh-my-opencode, you will never go back"
- d0t3ch

"I haven't really been able to articulate exactly what makes it so great yet, but the development experience has reached a completely different dimension." - 苔硯:こけすずり

"Experimenting with open code, oh my opencode and supermemory this weekend to build some minecraft/souls-like abomination." "Asking it to add crouch animations while I go take my post-lunch walk. [Video]" - MagiMetal

"You guys should pull this into core and recruit him. Seriously. It's really, really, really good."
- Henning Kilset

"Hire @yeon_gyu_kim if you can convince him, this dude has revolutionized opencode."
- mysticaltech

"Oh My OpenCode Is Actually Insane" - YouTube - Darren Builds AI

You're juggling Claude Code, Codex, random OSS models. Configuring workflows. Debugging agents.

We did the work. Tested everything. Kept what actually shipped.

Install OmO. Type ultrawork. Done.

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, but seriously, let an agent do it. Humans fat-finger configs.

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

We're past the era of reading docs. Just paste this into your agent:

Read this and tell me why it's not just another boilerplate: https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/dev/README.md

You're actually reading this? Wild.

Install. Type ultrawork (or ulw). Done.

Everything below, every feature, every optimization, you don't need to know it. It just works.

Even only with following subscriptions, ultrawork will work well (this project is not affiliated, this is just personal recommendation):

• ChatGPT Subscription ($20)
• Kimi Code Subscription ($0.99) (*only this month)
• GLM Coding Plan ($10)
• If you are eligible for pay-per-token, using kimi and gemini models won't cost you that much.

Sisyphus (claude-opus-4-6 / kimi-k2.5 / glm-5 ) is your main orchestrator. He plans, delegates to specialists, and drives tasks to completion with aggressive parallel execution. He does not stop halfway.

Hephaestus (gpt-5.3-codex) is your autonomous deep worker. Give him a goal, not a recipe. He explores the codebase, researches patterns, and executes end-to-end without hand-holding. The Legitimate Craftsman.

Prometheus (claude-opus-4-6 / kimi-k2.5 / glm-5 ) is your strategic planner. Interview mode: it questions, identifies scope, and builds a detailed plan before a single line of code is touched.

Every agent is tuned to its model's specific strengths. No manual model-juggling. Learn more →

Anthropic blocked OpenCode because of us. That's why Hephaestus is called "The Legitimate Craftsman." The irony is intentional.

We run best on Opus, but Kimi K2.5 + GPT-5.3 Codex already beats vanilla Claude Code. Zero config needed.

When Sisyphus delegates to a subagent, it doesn't pick a model. It picks a category. The category maps automatically to the right model:

Agent says what kind of work. Harness picks the right model. You touch nothing.

You dialed in your Claude Code setup. Good.

Every hook, command, skill, MCP, plugin works here unchanged. Full compatibility, including plugins.

LSP, AST-Grep, Tmux, MCP actually integrated, not duct-taped together.

• LSP: lsp_rename, lsp_goto_definition, lsp_find_references, lsp_diagnostics. IDE precision for every agent
• AST-Grep: Pattern-aware code search and rewriting across 25 languages
• Tmux: Full interactive terminal. REPLs, debuggers, TUI apps. Your agent stays in session
• MCP: Web search, official docs, GitHub code search. All baked in

MCP servers eat your context budget. We fixed that.

Skills bring their own MCP servers. Spin up on-demand, scoped to task, gone when done. Context window stays clean.

The harness problem is real. Most agent failures aren't the model. It's the edit tool.

"None of these tools give the model a stable, verifiable identifier for the lines it wants to change... They all rely on the model reproducing content it already saw. When it can't - and it often can't - the user blames the model."

- Can Bölük, The Harness Problem

Inspired by oh-my-pi, we implemented Hashline. Every line the agent reads comes back tagged with a content hash:

11#VK: function hello() {
22#XJ:   return "world";
33#MB: }

The agent edits by referencing those tags. If the file changed since the last read, the hash won't match and the edit is rejected before corruption. No whitespace reproduction. No stale-line errors.

Grok Code Fast 1: 6.7% → 68.3% success rate. Just from changing the edit tool.

Run /init-deep. It generates hierarchical AGENTS.md files:

project/
├── AGENTS.md              ← project-wide context
├── src/
│   ├── AGENTS.md          ← src-specific context
│   └── components/
│       └── AGENTS.md      ← component-specific context

Agents auto-read relevant context. Zero manual management.

Complex task? Don't prompt and pray.

/start-work calls Prometheus. Interviews you like a real engineer, identifies scope and ambiguities, builds a verified plan before touching code. Agent knows what it's building before it starts.

Skills aren't just prompts. Each brings:

• Domain-tuned system instructions
• Embedded MCP servers, on-demand
• Scoped permissions. Agents stay in bounds

Built-ins: playwright (browser automation), git-master (atomic commits, rebase surgery), frontend-ui-ux (design-first UI).

Add your own: .opencode/skills/*/SKILL.md or ~/.config/opencode/skills/*/SKILL.md.

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

3. Verify removal

   opencode --version
   # Plugin should no longer be loaded

Features you'll think should've always existed. Once you use them, you can't go back.

Want the philosophy? Read the Ultrawork Manifesto.

I burned through $24K in LLM tokens on personal projects. Tried every tool. Configured everything to death. OpenCode won.

Every problem I hit, the fix is baked into this plugin. Install and go.

If OpenCode is Debian/Arch, OmO is Ubuntu/Omarchy.

Heavy influence from AmpCode and Claude Code. Features ported, often improved. Still building. It's OpenCode.

Other harnesses promise multi-model orchestration. We ship it. Stability too. And features that actually work.

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?
• What's fastest for daily driving?
• What are competitors shipping?

This plugin is the distillation. Take the best. Got improvements? PRs welcome.

Stop agonizing over harness choices. I'll research, steal the best, and ship it here.

Sounds arrogant? Have a better way? Contribute. You're welcome.

No affiliation with any project/model mentioned. Just personal experimentation.

99% of this project was built with OpenCode. I don't really know TypeScript. But I personally reviewed and largely rewrote this doc.
