ravi-system

The daemon that gives Claude a life

---

Ravi is a multi-agent messaging daemon built on the Claude Agent SDK. It connects Claude to WhatsApp, Telegram, and Discord via omni, with session routing, message queuing, and automation — all running locally with embedded NATS JetStream.

Architecture

ravi daemon start
  ├── nats-server :4222 (JetStream)
  ├── omni API    :8882 (child process)
  │     ├── WhatsApp (Baileys)
  │     ├── Telegram
  │     └── Discord
  └── ravi bot
        ├── OmniConsumer  → JetStream pull consumer
        ├── Claude Agent SDK (sessions, tools)
        ├── OmniSender    → HTTP POST /api/v2/messages/send
        └── Runners (cron, heartbeat, triggers, outbound)

Features

Core

• Multi-Channel — WhatsApp, Telegram, Discord via omni
• Multi-Agent — Multiple agents with different models, modes, and capabilities
• Session Routing — Per-peer, per-group, per-thread session isolation
• Message Queue — Smart interrupt handling with debounce support
• REBAC Permissions — Fine-grained relation-based access control

Automation

• Heartbeat — Proactive agent runs on schedule to check pending tasks
• Cron Jobs — Schedule prompts with cron expressions, intervals, or one-shot times
• Event Triggers — Subscribe to NATS topics and fire agent prompts on events
• Outbound Queues — Automated outreach campaigns with follow-ups and qualification
• Cross-Session Messaging — Agents can send, ask, answer, and execute across sessions

Media & AI

• Audio Transcription — Voice messages via OpenAI Whisper
• Video Analysis — YouTube and local videos via Gemini
• Image Generation — Via Gemini Imagen
• Media Sending — Images, videos, documents, stickers via any channel

Operations

• Daemon Mode — Run as system service (launchd/systemd)
• Live Event Stream — Real-time colored view of all NATS events
• Contact Management — Tags, notes, identities, opt-out, per-group tags
• Spec Mode — Collaborative specification before implementation

Quick Start

# Install
git clone https://github.com/filipexyz/ravi.git
cd ravi
bun install && bun run build && bun link

# Setup (downloads nats-server, configures auth, creates agent)
ravi setup

# Configure omni in ~/.ravi/.env
#   OMNI_DIR=/path/to/omni-v2
#   DATABASE_URL=postgresql://postgres:[email protected]:5432/omni

# Start everything
ravi daemon start

# Connect WhatsApp
ravi whatsapp connect

How It Works

[WhatsApp / Telegram / Discord]
    → omni API
    → NATS JetStream (stream: MESSAGE)
    → OmniConsumer (pull consumer, ACK explicit)
    → ravi.{sessionKey}.prompt
    → RaviBot (Claude SDK)
    → ravi.{sessionKey}.response
    → Gateway → OmniSender (HTTP)
    → omni API
    → [WhatsApp / Telegram / Discord]

When messages arrive while an agent is processing:

• Tool running — message queues, waits for tool to finish, then interrupts
• No tool — interrupts immediately
• Debounce active — groups messages within time window
