Signal Integration

Complete Signal messenger integration with security-first contact management.

Feature Overview

Text & voice messaging — Send and receive text messages, voice notes, images, and attachments
Role-based permissions — Three-tier contact system (owner/trusted/untrusted) controls who can instruct your agent to execute commands, modify files, or access private information
New contact triage — Unknown senders are flagged for owner approval before the agent engages; prevents prompt injection via unsolicited messages
Voice transcription — Incoming voice messages transcribed via Whisper (or any STT engine) for processing
Voice replies — Generate spoken responses via TTS and send as audio attachments
Conversation history — Per-contact message logs with timestamps for context continuity
Typing indicators — Shows "typing..." in the recipient's Signal app before sending
Read & viewed receipts — Marks messages as read; sends "viewed" receipt for voice messages
UUID contact support — Handles both phone number and UUID-based Signal contacts
Instant wake — Triggers OpenClaw's /hooks/wake API on new messages for immediate response (no waiting for next heartbeat)
Auto-logging — All sent and received messages logged to conversation files
