iMessage/SMS CLI for macOS

A command-line interface for interacting with macOS Messages.app using AppleScript/osascript. List conversations, view message history, monitor for new messages, and send iMessages or SMS.

Prerequisites

System Requirements

1. macOS - This skill only works on macOS (Messages.app is macOS-only)
2. Messages.app configured - Must be signed into iCloud or have carrier SMS set up
3. Automation permissions - Terminal/Claude must have permission to control Messages.app

Granting Permissions

When first running these commands, macOS will prompt for automation permission:

1. Go to System Preferences > Security & Privacy > Privacy > Automation
2. Enable Terminal (or your terminal app) to control Messages
3. If using Claude Code, ensure the parent process has automation permissions
