Ralph TUI

AI Agent Loop Orchestrator - A terminal UI for orchestrating AI coding agents to work through task lists autonomously.

Ralph TUI connects your AI coding assistant (Claude Code, OpenCode, Factory Droid, Cursor CLI, Gemini CLI, Codex, Kiro CLI) to your task tracker and runs them in an autonomous loop, completing tasks one-by-one with intelligent selection, error handling, and full visibility.

See the Themes documentation for the full theme schema and creating custom themes.

Using Skills Directly in Your Agent

Install ralph-tui skills to your agent using add-skill:

# Install all skills to all detected agents globally
bunx add-skill subsy/ralph-tui --all

# Install to a specific agent
bunx add-skill subsy/ralph-tui -a claude-code -g -y
bunx add-skill subsy/ralph-tui -a kiro-cli -g -y

# Or use the ralph-tui wrapper (maps agent IDs automatically)
ralph-tui skills install
ralph-tui skills install --agent claude
ralph-tui skills install --agent kiro
# If symlinked installs are problematic, copy files instead:
ralph-tui skills install --copy

Use these slash commands in your agent:

/ralph-tui-prd           # Create a PRD interactively
/ralph-tui-create-json   # Convert PRD to prd.json
/ralph-tui-create-beads  # Convert PRD to Beads issues

This lets you create PRDs while referencing source files (@filename) and using your full conversation context—then use ralph-tui run for autonomous execution.

Custom Skills Directory

You can configure a custom skills_dir in your config file to use custom PRD skills:

# In .ralph-tui/config.toml or ~/.config/ralph-tui/config.toml
skills_dir = "/path/to/my-skills"

# Then use custom skills
ralph-tui create-prd --prd-skill my-custom-skill

Skills must be folders inside skills_dir containing a SKILL.md file.

Remote Instance Management

Control multiple ralph-tui instances running on different machines (VPS servers, CI/CD environments, development boxes) from a single TUI.

┌─────────────────────────────────────────────────────────────────┐
│  LOCAL [1]│ ● prod [2]│ ◐ staging [3]│ ○ dev [4]│      +       │
├─────────────────────────────────────────────────────────────────┤
│                                                                 │
│   Your local TUI can connect to and control remote instances    │
│                                                                 │
└─────────────────────────────────────────────────────────────────┘

Quick Start: Remote Control

On the remote machine (server):

# Start ralph with remote listener enabled
ralph-tui run --listen --prd ./prd.json

# First run generates a secure token - save it!
# ═══════════════════════════════════════════════════════════════
#                    Remote Listener Enabled
# ═══════════════════════════════════════════════════════════════
#   Port: 7890
#   New server token generated:
#   OGQwNTcxMjM0NTY3ODkwYWJjZGVmMDEyMzQ1Njc4OQ
#   ⚠️  Save this token securely - it won't be shown again!
# ═══════════════════════════════════════════════════════════════

On your local machine (client):

# Add the remote server
ralph-tui remote add prod server.example.com:7890 --token OGQwNTcxMjM0NTY3...

# Test the connection
ralph-tui remote test prod

# Launch TUI - you'll see tabs for local + remote instances
ralph-tui

Remote Listener Commands

Recommended: Use run --listen (runs engine with remote access):

# Start with remote listener on default port (7890)
ralph-tui run --listen --prd ./prd.json

# Start with custom port
ralph-tui run --listen --listen-port 8080 --epic my-epic

Token management:

# Rotate authentication token (invalidates old token immediately)
ralph-tui run --listen --rotate-token --prd ./prd.json

# View remote listener options
ralph-tui run --help

Remote Configuration Commands

# Add a remote server
ralph-tui remote add <alias> <host:port> --token <token>

# List all remotes with connection status
ralph-tui remote list

# Test connectivity to a specific remote
ralph-tui remote test <alias>

# Remove a remote
ralph-tui remote remove <alias>

# Push config to a remote (propagate your local settings)
ralph-tui remote push-config <alias>
ralph-tui remote push-config --all  # Push to all remotes

Push Configuration to Remotes

When managing multiple ralph-tui instances, you typically want them all to use the same configuration. The push-config command lets you propagate your local config to remote instances:

# Push config to a specific remote
ralph-tui remote push-config prod

# Preview what would be pushed (without applying)
ralph-tui remote push-config prod --preview

# Push to all configured remotes
ralph-tui remote push-config --all

# Force overwrite existing config without confirmation
ralph-tui remote push-config prod --force

# Push specific scope (global or project config)
ralph-tui remote push-config prod --scope global
ralph-tui remote push-config prod --scope project

How it works:

Reads your local config (~/.config/ralph-tui/config.toml or .ralph-tui/config.toml)
Connects to the remote instance
Checks what config exists on the remote
Creates a backup if overwriting (e.g., config.toml.backup.2026-01-19T12-30-00-000Z)
Writes the new config
Triggers auto-migration to install skills/templates

Scope selection:

--scope global: Push to ~/.config/ralph-tui/config.toml on remote
--scope project: Push to .ralph-tui/config.toml in remote's working directory
Without --scope: Auto-detects based on what exists locally and remotely

Security Model

Ralph uses a two-tier token system for secure remote access:

Token Type	Lifetime	Purpose
Server Token	90 days	Initial authentication, stored on disk
Connection Token	24 hours	Session authentication, auto-refreshed

Security features:

Without a token configured, the listener binds only to localhost (127.0.0.1)
With a token configured, the listener binds to all interfaces (0.0.0.0)
All connections require authentication
All remote actions are logged to ~/.config/ralph-tui/audit.log
Tokens are shown only once at generation time

Connection Resilience

Remote connections automatically handle network interruptions:

Auto-reconnect: Exponential backoff from 1s to 30s (max 10 retries)
Silent retries: First 3 retries are silent, then toast notifications appear
Status indicators: ● connected, ◐ connecting, ⟳ reconnecting, ○ disconnected
Metrics display: Latency (ms) and connection duration shown in tab bar

When connected to remote instances, a tab bar appears at the top of the TUI:

Key	Action
`1-9`	Jump directly to tab 1-9
`[`	Previous tab
`]`	Next tab
`Ctrl+Tab`	Next tab
`Ctrl+Shift+Tab`	Previous tab

The first tab is always "Local" (your current machine). Remote tabs show the alias you configured with connection status.

Managing Remotes from the TUI

You can add, edit, and delete remote servers directly from the TUI without leaving the interface:

Add Remote (a key):
Opens a form dialog to configure a new remote:

Alias: A short name for the remote (e.g., "prod", "dev-server")
Host: The server address (e.g., "192.168.1.100", "server.example.com")
Port: The listener port (default: 7890)
Token: The server token (displayed on the remote when you start with --listen)

Use Tab/Shift+Tab to move between fields, Enter to save, Esc to cancel.

Edit Remote (e key):
When viewing a remote tab, press e to edit its configuration. The form pre-fills with current values. You can change any field, including the alias.

Delete Remote (x key):
When viewing a remote tab, press x to delete it. A confirmation dialog shows the remote details before deletion.

Full Remote Control

When connected to a remote instance, you have full control:

View: Agent output, logs, progress, task list
Control: Pause, resume, cancel execution
Modify: Add/remove iterations, refresh tasks
Start: Begin new task execution

All operations work identically to local control with <100ms perceived latency.

Configuration Files

File	Purpose
`~/.config/ralph-tui/remote.json`	Server token storage
`~/.config/ralph-tui/remotes.toml`	Remote server configurations
`~/.config/ralph-tui/audit.log`	Audit log of all remote actions
`~/.config/ralph-tui/listen.pid`	Daemon PID file
