Oh-My-Openagent The open-source project oh-my-openagent, maintained by developer Yeongyu Kim and AI assistant Jobdori, announces support for OpenAI's Codex CLI via a new LazyCodex installer and a multi-harness refactor to support OpenCode, Codex, Pi, and others. The project claims Anthropic blocked OpenCode because of its usage, positioning itself as an orchestrator across models rather than a single provider. Testimonials praise its speed and capability, with one user reporting fixing 8,000 ESLint warnings in a day. Note OmO for Codex is here: try LazyCodex We loved Anthropic models enough to get blocked. Now we are backing Codex. If you are an OmO fan but the setup felt like too much, use LazyCodex. OmO for Codex has shipped: npx lazycodex-ai install Learn more at lazycodex.ai https://lazycodex.ai . Note Multi-Harness Agent OS Refactor in Progress We are restructuring the codebase to support multiple agent harnesses OpenCode, Codex, Pi, and others .

With Kimi K3 and GPT-5.6 Sol. 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 "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."

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, 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 three editions of the same product: two plugins that load into a host you already run, plus one standalone edition. Ultimate Edition omo for OpenCode — full omo. 11 agents, 54+ lifecycle hooks, 5 built-in MCPs, all slash commands, Team Mode, /goal , ultrawork — everything. Hashline edits are opt-in hashline edit: true . Light Edition omo for Codex CLI — the portable components that fit Codex's plugin system: rules , comment-checker , git-bash , lsp , ultrawork , ulw-loop , ulw-execute-continuation , and telemetry at the core, plus teammode and supporting components bootstrap , lcx , and more , plugin-scoped MCPs for grep app , context7 , git bash , and lsp , and the shared ast-grep skill. It installs Codex agent TOMLs into ~/.codex/agents/ . No OpenCode team tools — Codex CLI's own spawn/collaboration surface does that work. Senpi Edition standalone, beta — the native omo command with the OMO extension built in. It installs from omo-ai@beta rather than loading into OpenCode or Codex. Pick the edition s you want. | You want | Run | What lands on disk | |---|---|---| Ultimate OpenCode | bunx oh-my-openagent 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 oh-my-openagent install --platform=both | Both of the above | Senpi edition beta | npm i -g omo-ai@beta , then omo | The omo command: pinned senpi release with the OMO extension built in. Beta channel only; a bare npm i -g omo-ai fails by design. See the | lazycodex-ai defaults to the Codex Light installer and runs through Node/npm. --platform on the shared omo-agent-toolkit CLI still defaults to opencode Ultimate . - Already use OpenCode, or want the most-tested path? Choose Ultimate : bunx oh-my-openagent install . - Already use Codex CLI? Choose Light : npx lazycodex-ai install . - Want one command without installing a host first? Choose Senpi/native beta : npm i -g omo-ai@beta . Ultimate and Light are plugins that load into a host you already run. Senpi is standalone: it ships a pinned Senpi engine with OMO built in. For Senpi, the @beta tag is required; bare npm i -g omo-ai fails by design. Do not install plain omo from npm: it is an unrelated package by a different author. 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 , team , hyperplan , slash commands, the Light edition's Codex components, Team Mode, and uninstall. Don't summarize it; read it end to end. The published npm package and CLI binary are still named oh-my-opencode dual-published as oh-my-openagent during the rename transition . Inside opencode.json , the compatibility layer prefers the plugin entry oh-my-openagent , while legacy oh-my-opencode entries still load with a warning. Runtime config is ~/.omo/omo.jsonc plus walked project .omo/omo.jsonc . Legacy oh-my-openagent.json c / oh-my-opencode.json c files are imported once by the migration engine and are not read afterward. The recommended bunx / npx invocation is oh-my-openagent install or the original oh-my-opencode install . Once installed, the short command is omo-agent-toolkit . The omo bin was removed from these packages in this major release; the name now belongs to the senpi-native edition, installed with npm i -g omo-ai@beta beta channel only . Do not use bunx omo or npx omo : omo on npm is a different, unrelated package by a different author, and those commands resolve to it. The senpi edition's package name is omo-ai . lazycodex-ai is a single-purpose Node/npm installer package: npx lazycodex-ai install routes directly to the Codex Light installer. It is not the Codex marketplace name the marketplace repository is code-yeongyu/lazycodex . Codex sees marketplace sisyphuslabs and plugin omo , enabled as omo@sisyphuslabs . Anonymous telemetry is enabled by default to track active installations DAU/WAU/MAU . For both products, a single event is sent at most once per UTC day per machine using a SHA256-hashed installation identifier never the raw hostname , and PostHog person profiles are not created. The main plugin emits omo daily active from plugin load plugin loaded and CLI run run started sources; the Codex CLI Light edition emits omo codex daily active from two sources install completed and session start . Opt out per product: - Main plugin: set "telemetry": false in oh-my-openagent config, OMO DISABLE POSTHOG=1 , or OMO SEND ANONYMOUS TELEMETRY=0 - Codex CLI Light edition: OMO CODEX DISABLE POSTHOG=1 or OMO CODEX SEND ANONYMOUS TELEMETRY=0 the global flags also disable Codex See Privacy Policy /code-yeongyu/oh-my-openagent/blob/dev/docs/legal/privacy-policy.md and Terms of Service /code-yeongyu/oh-my-openagent/blob/dev/docs/legal/terms-of-service.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-openagent/refs/heads/dev/README.md We are restructuring the codebase to support multiple agent harnesses OpenCode, Codex, Pi, Claude Code, and others . The most urgent work is the package layering refactor: separating pure TypeScript core logic, MCP servers, skills, and adapter shims into distinct layers so the same logic can be reused across harnesses without duplication. If you want to contribute, read the ROADMAP /code-yeongyu/oh-my-openagent/blob/dev/ROADMAP.md first. PRs related to this refactor should use the ROADMAP label so we can track them.

Sisyphus claude-opus-5 / kimi-k3 / / gpt-5.6-sol is your main orchestrator. He plans, delegates to specialists, and drives tasks to completion with aggressive parallel execution. He does not stop halfway. Claude Opus 5 and Kimi K3 are the recommended defaults. glm-5.2 Hephaestus gpt-5.6-sol through OpenAI, GitHub Copilot, Vercel, or OpenCode at medium effort 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-fable-5 / kimi-k3 is your strategic planner. Interview mode: he asks 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 → /code-yeongyu/oh-my-openagent/blob/dev/docs/guide/overview.md Anthropic blocked OpenCode because of us. That's why Hephaestus is called "The Legitimate Craftsman." The irony is intentional.We run best on Opus or Kimi K3, but Kimi K3 + GPT-5.6 Sol already beats vanilla Claude Code. Zero config needed. One agent is fast. A coordinated team is devastating . Team Mode turns oh-my-openagent from "one agent with subagents" into a real multi-agent system. A lead agent orchestrates a team of category-specialized members, all running in parallel and communicating through dedicated tools team create , team send message , team task create , team status , ... . Watch every member work simultaneously in a tmux layout with focus + grid windows. // ~/.omo/omo.jsonc or project .omo/omo.jsonc { "team mode": { "enabled": true, "max parallel members": 4, "tmux visualization": true } } Restart opencode and the team tool family unlocks. Two skills already ride on top: — 5 hostile agents tear apart your plan from orthogonal angles before a single line of code is written. hyperplan — 3 vulnerability hunters + 2 PoC engineers audit your codebase in parallel, with severity calibrated by security-research actual exploitability . Off by default. Enable it when you want it. Full Team Mode guide → When Sisyphus delegates to a subagent, it doesn't pick a model. It picks a category . The category maps automatically to the right model: | Category | What it's for | |---|---| visual-engineering | Frontend, UI/UX, design | deep | Autonomous research + execution | quick | Single-file changes, typos | ultrabrain | Hard logic, architecture decisions | The agent says what kind of work it needs; the harness picks the right model. ultrabrain routes to GPT-5.6 Sol max OpenAI / Vercel, then GitHub Copilot, then OpenCode . 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, and 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. They spin up on demand, scoped to the task, and go away when done. The context window stays clean. The harness problem is real. Most agent failures aren't the model's fault; 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." Inspired by oh-my-pi https://github.com/can1357/oh-my-pi , we built Hashline . When hashline edit is enabled, 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 has changed since the last read, the hash won't match and the edit is rejected before any 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. Prometheus interviews you like a real engineer , identifies scope and ambiguities, and writes a verified plan to .omo/plans/ before touching code. /ulw-execute then starts an Atlas work session from that plan. The 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 so agents stay in bounds.
