CLI

ReignCode CLI options and commands.

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

reigncode

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

reigncode run "Explain how closures work in JavaScript"

tui

Start the ReignCode terminal user interface.

reigncode [project]

Flags

Flag	Short	Description
`--continue`	`-c`	Continue the last session
`--session`	`-s`	Session ID to continue
`--fork`		Fork the session when continuing (use with `--continue` or `--session`)
`--prompt`		Prompt to use
`--model`	`-m`	Model to use in the form of provider/model
`--agent`		Agent to use
`--port`		Port to listen on
`--hostname`		Hostname to listen on

Commands

The ReignCode CLI also has the following commands.

agent

Manage agents for ReignCode.

reigncode agent [command]

attach

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

reigncode attach [url]

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

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

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

Flags

Flag	Short	Description
`--dir`		Working directory to start TUI in
`--session`	`-s`	Session ID to continue

create

Create a new agent with custom configuration.

reigncode agent create

This command will guide you through creating a new agent with a custom system prompt and tool configuration.

list

List all available agents.

reigncode agent list

auth

Command to manage credentials and login for providers.

reigncode auth [command]

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

reigncode auth login

When ReignCode 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.

list

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

reigncode auth list

Or the short version.

reigncode auth ls

logout

Logs you out of a provider by clearing it from the credentials file.

reigncode auth logout

github

Manage the GitHub agent for repository automation.

reigncode github [command]

install

Install the GitHub agent in your repository.

reigncode github install

This sets up the necessary GitHub Actions workflow and guides you through the configuration process. Learn more.

run

Run the GitHub agent. This is typically used in GitHub Actions.

reigncode github run

Flags

Flag	Description
`--event`	GitHub mock event to run the agent for
`--token`	GitHub personal access token

mcp

Manage Model Context Protocol servers.

reigncode mcp [command]

add

Add an MCP server to your configuration.

reigncode mcp add

This command will guide you through adding either a local or remote MCP server.

list

List all configured MCP servers and their connection status.

reigncode mcp list

Or use the short version.

reigncode mcp ls

auth

Authenticate with an OAuth-enabled MCP server.

reigncode mcp auth [name]

If you don’t provide a server name, you’ll be prompted to select from available OAuth-capable servers.

You can also list OAuth-capable servers and their authentication status.

reigncode mcp auth list

Or use the short version.

reigncode mcp auth ls

logout

Remove OAuth credentials for an MCP server.

reigncode mcp logout [name]

debug

Debug OAuth connection issues for an MCP server.

reigncode mcp debug <name>

models

List all available models from configured providers.

reigncode 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.

run

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

reigncode run [message..]

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

reigncode run Explain the use of context in Go

You can also attach to a running reigncode serve instance to avoid MCP server cold boot times on every run:

# Start a headless server in one terminal
reigncode serve

# In another terminal, run commands that attach to it
reigncode run --attach http://localhost:4096 "Explain async/await in JavaScript"
