# imsg

Use `imsg` to read and send iMessage/SMS via macOS Messages.app.

## When to Use

Use when:

- User explicitly asks to send iMessage or SMS
- Reading iMessage conversation history
- Checking recent Messages.app chats
- Sending to phone numbers or Apple IDs

## When NOT to Use

Do not use when:

- Telegram messages -> use `message` tool with `channel:telegram`
- Signal messages -> use Signal channel if configured
- WhatsApp messages -> use WhatsApp channel if configured
- Discord messages -> use `message` tool with `channel:discord`
- Slack messages -> use `slack` skill
- Group chat management (adding/removing members) -> not supported
- Bulk/mass messaging -> always confirm with user first
- Replying in current conversation -> just reply normally (OpenClaw routes automatically)

## Requirements

- macOS with Messages.app signed in
- Full Disk Access for terminal
- Automation permission for Messages.app (for sending)

## Common Commands

### List Chats

```bash
imsg chats --limit 10 --json
```

### View History

```bash
# By chat ID
imsg history --chat-id 1 --limit 20 --json

# With attachments info
imsg history --chat-id 1 --limit 20 --attachments --json
```

imsg watch --chat-id 1 --attachments
```
