CLI

The Lunos CLI by default starts the TUI when run without any arguments.

lunos

But it also accepts commands as documented on this page. This allows you to interact with Lunos programmatically.

lunos run "Explain how closures work in JavaScript"

---

tui

Start the Lunos terminal user interface.

lunos [project]

Flags

--model	-m	Model to use in the form of provider/model
--agent		Agent to use
--auto		Auto-approve permissions that are not explicitly denied
--port		Port to listen on

Commands

The Lunos CLI also has the following commands.

---

agent

Manage agents for Lunos.

lunos agent [command]

---

create

Create a new agent with custom configuration.

lunos agent create

This command will guide you through creating a new agent with a custom system prompt and permission configuration. Anything you don’t allow is denied in the generated agent’s frontmatter.

Flags

Flag	Short	Description
--path		Directory to write the agent file to (defaults to global or .opencode/agent based on the prompt)
--description		What the agent should do
--mode		Agent mode: all, primary, or subagent

--model	-m	Model to use, in provider/model format

Passing all of --path, --description, --mode, and --permissions runs the command non-interactively.

---

list

List all available agents.

lunos agent list

---

attach

Attach a terminal to an already running Lunos backend server started via serve or web commands.

lunos attach [url]

This allows using the TUI with a remote Lunos backend. For example:

# Start the backend server for web/mobile access
lunos web --port 4096 --hostname 0.0.0.0

# In another terminal, attach the TUI to the running backend
lunos attach http://10.20.30.40:4096

Flags

Flag	Short	Description

--username	-u	Basic auth username (defaults to OPENCODE_SERVER_USERNAME or lunos)

---

auth

Command to manage credentials and login for providers.

lunos auth [command]

login

Lunos is powered by the provider list at Models.dev, so you can use lunos auth login to configure API keys for any provider you’d like to use. This is stored in ~/.local/share/opencode/auth.json.

When Lunos starts up it loads the providers from the credentials file. And if there are any keys defined in your environments or a .env file in your project.

Flags

Flag	Short	Description
--provider	-p	Provider ID or name to log in to
--method	-m	Login method label to use, skipping method selection

---

list

Lists all the authenticated providers as stored in the credentials file.

lunos auth list

Or the short version.

lunos auth ls

---

logout

lunos models [provider]

This command displays all models available across your configured providers in the format provider/model.

This is useful for figuring out the exact model name to use in your config.

You can optionally pass a provider ID to filter models by that provider.

lunos models anthropic

Flags

Flag	Description
--refresh	Refresh the models cache from models.dev
--verbose	Use more verbose model output (includes metadata like costs)

Use the --refresh flag to update the cached model list. This is useful when new models have been added to a provider and you want to see them in Lunos.

---

run

Run Lunos in non-interactive mode by passing a prompt directly.

lunos run [message..]

This is useful for scripting, automation, or when you want a quick answer without launching the full TUI. For example.
