AI

Omarchy treats AI coding agents as first-class citizens, but it doesn't pick a favorite for you. Instead, every major coding-agent CLI comes pre-wired as a lazy-loaded launcher. The launchers are tiny mise-managed stubs in ~/.local/bin/, so nothing is downloaded until the first time you actually run one. Hermes is the exception: nothing is stubbed for it, and choosing it installs Hermes Desktop, as Desktop apps below explains. Invoke any of these and authenticate when prompted:

Command	Agent
claude	Claude Code
codex	OpenAI Codex
opencode	OpenCode
agy	Google Antigravity CLI
copilot	GitHub Copilot CLI
crush	Crush
grok	Grok CLI from xAI
pi	Mario Zechner's Pi
omp	Oh My Pi
ori	Ori, OpenRouter's harness
hermes	Hermes, Nous Research's agent
muse	Muse Code, Meta's coding agent
cursor-agent	Cursor CLI

ori is the odd one out: it runs the other harnesses against OpenRouter's whole model catalog, so ori claude, ori codex, or ori opencode start those agents on whichever model you point them at, and ori code is Ori's own agent.

To wrap an additional CLI the same way, run omarchy-mise-install <package> [command-name]. The stubs are kept current along with everything else mise manages when you run omarchy update (or the mup alias).

The default agent

Pick your default agent with omarchy default agent <name> or under Setup > Defaults > Agent in the Omarchy Menu (Super + Space). If the agent isn't installed yet, picking it installs it first. A fresh Omarchy will invite you to make this choice with a one-time notification.

Choosing Claude also attempts to set up its browser extension for Chromium, Chrome, Brave, Brave Origin, and Edge. The extension setup applies to all users and may ask for your system password; cancelling or a failed extension install still selects and launches Claude. Restart your browser, enable the extension if prompted, and sign in to Claude to finish connecting it. Run /chrome in Claude to check the connection. Firefox and Zen do not support this extension. If Claude was already your default before this setup was added, select it again to install the extension.

Muse Code — Meta's muse — uses a preinstalled mise stub like the other agents. Picking it as the default installs Meta's official launcher through mise's HTTP backend. The launcher verifies and updates the native binary for your machine.

Once you've chosen, Super + Shift + Ctrl + A launches the default agent in a dedicated terminal window (or brings up the picker if you haven't chosen yet). You can also launch it straight into a task with omarchy agent prompt "Review this project". Agents launched this way run unattended in their respective don't-stop-to-ask modes, so be ready for them to actually do things! And since agents refuse to remember trust for your home directory, launches from $HOME start in ~/Work instead.

There are terminal shortcuts too: a runs the default agent inline in the current terminal, while c, cx, and cy start OpenCode, Claude Code, and Codex directly (again in their auto-approving modes). Theme changes sync to the agents as well: Claude Code, Pi, OpenCode, and Hermes (once Omarchy has installed it) all follow along when you switch the Omarchy theme.

The agents panel

The top bar has an agents icon. Before you've set up an agent, its panel walks you through signing in to Claude, Codex, or Grok, and the first one becomes your default agent. After that, the panel puts every subscription on one page: each agent and account with its plan and the percentage used of its 5-hour session and weekly limits (or the remaining prepaid balance), under a line that rotates through what you've used across all of them, like tokens this week and your most used model. Under Make something it offers starter prompts for a new theme, plugin, or app that hand the task to your default agent. Apps are built the way Omarchy's own Hype, Monologue, and Omacut are, in C++ and Qt Quick, following the omarchy-app agent skill, and the compiler and Qt pieces they need come installed. Claude Code, Codex, and Fireworks are covered out of the box.

Left-click the bar icon for the panel, right-click to launch your default agent. The usage records behind it are regenerated every 15 minutes by omarchy agent usage-update, and the panel can even merge usage from your other machines via a synced folder. See the README under $OMARCHY_PATH/shell/plugins/agents/ for the full settings.

Several subscriptions

If you pay for more than one Claude or Codex plan — a personal Max and a work one, say — Omarchy can keep them all signed in and move between them. Add a subscription with the + in the agents panel, which walks you through it right there, or with omarchy agent account add claude Work (or codex). It installs the CLI if it's missing. The first account for a provider signs in through your normal browser, right where the CLI always looks. Every one after that signs in through a private window, so the account your browser is already signed in to doesn't get picked up by mistake; sign in there as the account you're adding, and close any private window you already had open first. Grok can be signed in the same way, but only one Grok account for now. Never log out of the CLI to do this: logging out revokes the saved sign-in, and that account would have to be added again.

One account per provider is active, and every new session starts as it: cx, cy, a plain claude or codex, and anything launched through omarchy agent. Switch with omarchy agent account use work (and back with omarchy agent account use main), or in the panel by pressing an account's number and then Enter (or clicking its Use button). Sessions that are already running stay on the account they started with. Conversation history, settings, skills, and plugins are shared across accounts, so claude --continue in the same folder picks up where you left off on the new account.

With more than one account, the panel shows each account's limits side by side, with the active one marked. By default Omarchy notifies you when the active account passes 95% of a limit, and clicking the notification switches to the account with the most headroom. Hover an account's line in the panel and click the Autoswitch that appears beside Use (or press m), or run omarchy agent account mode auto, to have it switch on its own instead; while it's on, Autoswitch takes Use's place, and clicking it again goes back to notifying. Add a number to change the threshold, as in omarchy agent account mode auto 90. If every account is over the threshold, you'll hear about it once, along with which account frees up first. While an active account is within 15 points of its threshold (80% at the default), its limits are checked every three minutes rather than every 15.

omarchy agent account list shows every account and its latest limits, omarchy agent account remove work forgets one, and omarchy agent account rename primary Hey renames one (or click an account's name in the panel). These commands work on your default agent's accounts; to reach the other provider, name it first, as in omarchy agent account use codex side. The login you already had in ~/.claude or ~/.codex is the Main account and stays where it is. An account left unused for more than about eight hours shows its last known limits until a session runs in it again. MCP servers you had when an account was added come along to it, but ones you add later with claude mcp add only reach the account you added them in. Claude Desktop and editors that start claude themselves don't follow the switch.

Crash diagnosis

Omarchy watches systemd-coredump for process crashes. When something segfaults, you'll get a "Process crashed" notification — click it, and the crash is handed to your default agent along with Omarchy's diagnose-crash skill, which walks the agent through establishing the facts from the core dump and deciding whether the crash is worth reporting upstream. You can also run it by hand against any PID from coredumpctl list with omarchy agent crash <pid>.

The watching is on by default. Turn it off under Trigger > Toggle > Crash Capture (or with omarchy toggle crash-capture) and the notifications stop; omarchy agent crash <pid> still works by hand.

Crashes can also be silenced one program at a time, which is what the diagnosis offers you at the end. omarchy crash mute hyprland stops the notifications for that program only, omarchy crash mute hyprland off brings them back, and omarchy crash mute on its own lists what you've muted. It takes the binary's path as happily as its name, so omarchy crash mute /usr/bin/hyprland does the same thing. Quote a name with a space in it, as in omarchy crash mute 'Some App'. Everything else still notifies, and the muted program still crashes — this hides the reminder, it doesn't fix anything.

Desktop apps

The Install > AI menu also carries a few graphical AI apps: the ChatGPT desktop app, the Claude desktop app (Anthropic's Linux beta, with Chat, Cowork, and Claude Code tabs), Grok Bot for chatting with xAI's models, Hermes Desktop, OpenClaw, and the Perplexity desktop app.

Hermes Desktop is the one to know about, because a machine has one Hermes, and it is the app's: Hermes is only ever installed through the app, and the hermes command the default agent runs is the app's. Choosing Hermes as the default agent installs the same thing the Install > AI entry does: the package, and a Hermes runtime under ~/.hermes set up by Hermes' own installer, which takes a few minutes the first time. That runtime is the one Hermes the terminal hermes command, the default agent and the app all use, and it updates itself with hermes update rather than waiting on an Omarchy release. Installing it also hands Hermes the Omarchy theme as a skin named omarchy, which every Hermes surface follows as you switch themes; pick another under Hermes' Appearance settings or with /skin if you'd rather it didn't, and Omarchy leaves that choice alone. Removing the app under Remove > AI closes Hermes first, gateway included, takes that runtime with it, and keeps your chats, memories, and the skills Hermes wrote for itself unless you tell it otherwise: it asks, defaulting to no, whether that data and your connection settings should go too.

OpenClaw's desktop experience is its Control UI, which opens as a web app backed by its own local gateway. OpenClaw updates arrive through Omarchy's package updates, so skip the Control UI's own "Update Gateway" button: it would try to write into the package-managed install and fail. Removing OpenClaw under Remove > AI takes the gateway service and the app with it and then asks whether ~/.openclaw should go too, since that holds your chats and credentials alongside the plugin runtimes OpenClaw downloads for itself; the default keeps it.

Local LLMs

Omarchy recommends two ways of running local LLM models: LM Studio and Ollama. LM Studio provides a GUI interface for finding open-weight models, installing them, and running them. It's a great way to get going easily. Ollama offers a CLI for doing so similarly. But if you're new to local models, I'd start with LM Studio. You can install either under Install > AI in the Omarchy Menu.

The Omarchy Skill

Agent skills help AI use specific tools in a specific way, and Omarchy ships with a default skill for tailoring the system. Like tweaking your Hyprland config, adjusting the bar, or even creating a new theme from scratch. It's symlinked into the skill directories for Claude Code (~/.claude/skills), Codex (~/.codex/skills), Pi (~/.pi/agent/skills), Antigravity (~/.gemini/config/skills), Hermes (~/.hermes/skills and each ~/.hermes/profiles/*/skills), and the generic ~/.agents/skills location, so most harnesses pick it up automatically.

But you should treat this skill as experimental. Different models will use it to different effect. It's best to run in plan mode first, so you have an idea of what the agent would like to change. And then be ready to rollback changes or even invoking omarchy reinstall configs, if the agent makes a mess of everything.
