[!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

This is oh-my-openagent, running Team Mode. 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.

Reviews

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

Oh My OpenAgent

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.

Installation

oh-my-openagent ships in two editions of the same product:

• Ultimate Edition (omo for OpenCode) — full omo. 11 agents, 54+ lifecycle hooks, 5 built-in MCPs, all slash commands, Team Mode, ulw-loop, ultrawork, hashline edits — everything.
• Light Edition (omo for Codex CLI) — the portable components that fit Codex's plugin system: rules, comment-checker, git-bash, lsp, ultrawork, ulw-loop, start-work-continuation, and telemetry, plus plugin-scoped MCPs for grep_app, context7, codegraph, git_bash, and lsp, and the shared ast-grep skill. No agent orchestration and no team_* tools — Codex CLI's own surface does that work.

Pick the edition(s) you want.

TL;DR

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

lazycodex-ai defaults to the Codex Light installer and runs through Node/npm. --platform on the shared omo CLI still defaults to opencode (Ultimate).

For Humans

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/.

For LLM Agents

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 8 Codex components, Team Mode, and uninstall. Don't summarize it; read it end to end.

Note on package and command names

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. Plugin config files still commonly use oh-my-opencode.json[c]; both legacy and renamed basenames are recognized.

The recommended bunx/npx invocation is oh-my-openagent install (or the original oh-my-opencode install). The package also ships omo as a bin alias, but do not use bunx omo or npx omo — omo is a different, unrelated npm package by a different author, and the package manager may resolve the wrong one. 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.

Telemetry

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)

Skip This README

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

ROADMAP

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 first. PRs related to this refactor should use the ROADMAP label so we can track them.

Highlights

🪄 ultrawork

You're actually reading this? Wild.

Install. Type ultrawork (or ulw). Done.

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

Even with only the following subscriptions, ultrawork works well (this project is not affiliated; these are personal recommendations):

• ChatGPT Subscription ($20)
• Kimi Code Subscription ($19)
• GLM Coding Plan ($10)
• If you're eligible for pay-per-token, using Kimi and Gemini models won't cost much.

	Feature	Edition	What it does
🤖	Discipline Agents	Ultimate	Sisyphus orchestrates Hephaestus, Oracle, Librarian, Explore. A full AI dev team in parallel.
🧩	Codex CLI Light Edition	Light	Portable OMO components (rules, comment-checker, git-bash, LSP, ultrawork, ulw-loop, start-work continuation, telemetry) running inside OpenAI Codex CLI. Install via npx lazycodex-ai install.
👥	Team Mode (v4.0, opt-in)	Ultimate	Lead agent + up to 8 parallel members, real-time tmux visualization, dedicated team_* tools. Powers hyperplan (5 hostile critics) and security-research (3 hunters + 2 PoC engineers). Docs →
⚡	ultrawork / ulw	Both	One word. Every agent activates. Doesn't stop until done.
🚪	IntentGate	Ultimate	Analyzes true user intent before classifying or acting. No more literal misinterpretations. (Light edition only recognises the ultrawork/ulw keyword.)
🔗	Hash-Anchored Edit Tool	Ultimate	LINE#ID content hash validates every change. Zero stale-line errors. Inspired by oh-my-pi. The Harness Problem →
🛠️	LSP integration	Both	Diagnostics, navigation, symbols, workspace rename. IDE precision for agents. Same LSP MCP server in both editions.

Edition legend. Ultimate = OpenCode-only (bunx oh-my-openagent install). Light = Codex CLI-only (npx lazycodex-ai install). Both = shipped in both editions, often with slightly different implementations under the hood.

Discipline Agents

Sisyphus (claude-opus-5 / kimi-k3 / 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. Claude Opus 5 and Kimi K3 are the recommended defaults.

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 →

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.

Team Mode (v4.0)

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.

// .opencode/oh-my-openagent.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:

• hyperplan — 5 hostile agents tear apart your plan from orthogonal angles before a single line of code is written.
• security-research — 3 vulnerability hunters + 2 PoC engineers audit your codebase in parallel, with severity calibrated by actual exploitability.

Off by default. Enable it when you want it. Full Team Mode guide →

Agent Orchestration

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 now routes to GPT-5.6 Sol xhigh through OpenAI or Vercel when available, then GPT-5.6 Sol xhigh. You touch nothing.

Claude Code Compatibility

You dialed in your Claude Code setup. Good.

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

World-Class Tools for Your Agents

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.

Skill-Embedded MCPs

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.

Codes Better. Hash-Anchored Edits

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."

- Can Bölük, The Harness Problem

Inspired by oh-my-pi, we built 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 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.

Deep Initialization. /init-deep

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.

Planning. Prometheus

Complex task? Don't prompt and pray.

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

Skills

Skills aren't just prompts. Each brings:

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

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

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

Uninstallation

To remove oh-my-openagent:

1. Remove the plugin from your OpenCode config

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

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

2. Remove configuration files (optional)

   # Remove plugin config files recognized during the compatibility window
   rm -f ~/.config/opencode/oh-my-openagent.jsonc ~/.config/opencode/oh-my-openagent.json \
         ~/.config/opencode/oh-my-opencode.jsonc ~/.config/opencode/oh-my-opencode.json
   
   # Remove project config (if exists)
   rm -f .opencode/oh-my-openagent.jsonc .opencode/oh-my-openagent.json \
         .opencode/oh-my-opencode.jsonc .opencode/oh-my-opencode.json
   

3. Verify removal

   opencode --version
   # Plugin should no longer be loaded
   

4. Remove omo-codex (Codex CLI Light edition)

   npx lazycodex-ai uninstall
   # backward-compatible alias:
   npx lazycodex-ai cleanup
   
   omo uninstall --platform=codex
   # backward-compatible alias:
   omo cleanup --platform=codex
   

   The uninstall command removes managed sisyphuslabs Codex cache/marketplace state, strips omo@sisyphuslabs plugin and hook-state blocks from ~/.codex/config.toml after writing a backup, and removes agent TOML links listed in the install manifest. If a specific project still has old project-local Codex plugin state, run the command from that project or pass --project <path>; it repairs known project-local .codex/config.toml conflicts and reports project-local .codex artifacts without deleting project-owned files.

Features

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

See full Features Documentation.

Quick Overview:

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, oh-my-openagent is Ubuntu/Omarchy.

Heavily influenced by 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 or model mentioned. Just personal experimentation.

Credit: The LazyCodex name idea is inspired by LazyVim. The Ultragoal and UltraQA ideas are inspired by oh-my-codex, reimplemented from concept for OmO.

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