A hat-based orchestration framework that keeps AI agents in a loop until the task is done.

> "Me fail English? That's unpossible!" - Ralph Wiggum

**[Documentation](https://mikeyobrien.github.io/ralph-orchestrator/)** | **[Getting Started](https://mikeyobrien.github.io/ralph-orchestrator/getting-started/quick-start/)** | **[Presets](https://mikeyobrien.github.io/ralph-orchestrator/guide/presets/)**

## Installation

### Via npm (Recommended)

```bash
npm install -g @ralph-orchestrator/ralph-cli
```

### Via GitHub Releases installer

```bash
curl --proto '=https' --tlsv1.2 -LsSf \
  https://github.com/mikeyobrien/ralph-orchestrator/releases/latest/download/ralph-cli-installer.sh | sh
```

### Via Cargo

```bash
cargo install ralph-cli
```

> Homebrew is not currently published from this repository's automated release flow. Prefer npm, Cargo, or the GitHub Releases installer.

## Quick Start

```bash
# 1. Initialize Ralph with your preferred backend
ralph init --backend claude

# 2. Plan your feature (interactive PDD session)
ralph plan "Add user authentication with JWT"
# Creates: specs/user-authentication/requirements.md, design.md, implementation-plan.md

# 3. Implement the feature
ralph run -p "Implement the feature in specs/user-authentication/"
```

Ralph iterates until it outputs `LOOP_COMPLETE` or hits the iteration limit.

For simpler tasks, skip planning and run directly:

```bash
ralph run -p "Add input validation to the /users endpoint"
```

## Web Dashboard (Alpha)

> **Alpha:** The web dashboard is under active development. Expect rough edges and breaking changes.

Ralph includes a web dashboard for monitoring and managing orchestration loops.

```bash
ralph web                              # starts Rust RPC API + frontend + opens browser
ralph web --no-open                    # skip browser auto-open
ralph web --backend-port 4000          # custom RPC API port
ralph web --frontend-port 8080         # custom frontend port
ralph web --legacy-node-api            # opt into deprecated Node tRPC backend
```

### MCP Server Workspace Scope

`ralph mcp serve` is scoped to a single workspace root per server instance.

```bash
ralph mcp serve --workspace-root /path/to/repo
```

Precedence is:

1. `--workspace-root`
2. `RALPH_API_WORKSPACE_ROOT`
3. current working directory

For multi-repo use, run one MCP server instance per repo/workspace. Ralph's current
control-plane APIs persist config, tasks, loops, planning sessions, and collections
under a single workspace root, so server-per-workspace is the deterministic model.

**Requirements:**
- Rust toolchain (for `ralph-api`)
- Node.js >= 18 + npm (for the frontend)

On first run, `ralph web` auto-detects missing `node_modules` and runs `npm install`.

To set up Node.js:

```bash
# Option 1: nvm (recommended)
nvm install    # reads .nvmrc

# Option 2: direct install
# https://nodejs.org/
```

For development:

```bash
npm install              # install frontend + legacy backend deps
npm run dev:api          # Rust RPC API (port 3000)
npm run dev:web          # frontend (port 5173)
npm run dev              # frontend only (default)
npm run dev:legacy-server  # deprecated Node backend (optional)
npm run test             # all frontend/backend workspace tests
```

## MCP Server Mode

Ralph can run as an MCP server over stdio for MCP-compatible clients:

```bash
ralph mcp serve
```

Use this mode from an MCP client configuration rather than an interactive terminal workflow.

## What is Ralph?

Ralph implements the [Ralph Wiggum technique](https://ghuntley.com/ralph/) — autonomous task completion through continuous iteration. It supports:

- **Multi-Backend Support** — Claude Code, Kiro, Gemini CLI, Codex, Amp, Copilot CLI, OpenCode
- **Hat System** — Specialized personas coordinating through events
- **Backpressure** — Gates that reject incomplete work (tests, lint, typecheck)
- **Memories & Tasks** — Persistent learning and runtime work tracking
- **5 Supported Builtins** — `code-assist`, `debug`, `research`, `review`, and `pdd-to-code-assist`, with more patterns documented as examples

## RObot (Human-in-the-Loop)

Ralph supports human interaction during orchestration via Telegram. Agents can ask questions and block until answered; humans can send proactive guidance at any time.

Quick onboarding (Telegram):

```bash
ralph bot onboard --telegram   # guided setup (token + chat id)
ralph bot status               # verify config
ralph bot test                 # send a test message
ralph run -c ralph.bot.yml -p  "Help the human"
```

```yaml
# ralph.yml
RObot:
  enabled: true
  telegram:
    bot_token: "your-token"  # Or RALPH_TELEGRAM_BOT_TOKEN env var
```

- **Agent questions** — Agents emit `human.interact` events; the loop blocks until a response arrives or times out
- **Proactive guidance** — Send messages anytime to steer the agent mid-loop
- **Parallel loop routing** — Messages route via reply-to, `@loop-id` prefix, or default to primary
- **Telegram commands** — `/status`, `/tasks`, `/restart` for real-time loop visibility

See the [Telegram guide](https://mikeyobrien.github.io/ralph-orchestrator/guide/telegram/) for setup instructions.
