This is oh-my-openagent, running Team Mode. With Kimi K2.6 and GPT-5.5.
Anthropic blocked OpenCode because of us. Yes, this is true. They want you locked in. Claude Code is a nice prison, but it's still a prison.
You don't need to pay $200 for 2 hours of work. 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

You're juggling Claude Code, Codex, and random OSS models. Configuring workflows. Debugging agents.
We did the work. Tested everything. Kept what actually shipped.
Install oh-my-openagent. Type ultrawork. Done.
oh-my-openagent ships in two editions of the same product:
rules, comment-checker, lsp, ultrawork, ulw-loop, start-work-continuation, and telemetry. No agent orchestration, no team_* tools, no built-in MCPs beyond LSP — Codex CLI's own surface does that work.Pick the edition(s) you want.
| You want | Run | What lands on disk |
|---|---|---|
| Ultimate (OpenCode) | bunx omo install (TUI walks you through it) |
Plugin registered in opencode.json + agent/model config + provider auth prompts |
| Light (Codex CLI) | npx lazycodex-ai install |
~/.codex/plugins/cache/sisyphuslabs/omo/ + local Codex marketplace cache + ~/.codex/config.toml marketplace/plugin/agent blocks + optional autonomous permissions + component CLIs in ~/.local/bin |
| Both | bunx omo install --platform=both |
Both of the above |
lazycodex-ai defaults to the Codex Light installer and runs through Node/npm. --platform on the shared omo CLI still defaults to opencode (Ultimate).
Strongly recommended: let an LLM agent install this for you. The Ultimate edition setup involves subscription detection, model selection across 11 agents, and per-provider authentication — humans fat-finger these. An LLM agent reads the full guide and walks every step correctly.
Paste this prompt into Claude Code, AmpCode, Cursor, or any agent:
Install and configure oh-my-openagent by following the instructions here:
https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/refs/heads/dev/docs/guide/installation.md
If you only want the Light edition (Codex CLI), the installer asks whether to configure Codex for autonomous full-permissions mode. You can run it yourself in one line:
npx lazycodex-ai install
# non-interactive recommended mode:
npx lazycodex-ai install --no-tui --codex-autonomous
For the Light edition, Bun is not required. Use npx lazycodex-ai install from a Node/npm environment. Global installation is not officially supported; the installer writes the Codex plugin into ~/.codex/.
Fetch the full guide and follow it step by step:
curl -fsSL https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/refs/heads/dev/docs/guide/installation.md
The guide covers: platform selection, the subscription interview, provider authentication (Anthropic / Gemini / Copilot / Z.ai / OpenCode Zen), the agent-to-model matching matrix, modes (ultrawork, search, analyze, team, hyperplan), slash commands, the Light edition's 5 Codex components, Team Mode, and uninstall. Don't summarize it; read it end to end.
