imsg

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

• 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

❌ DON'T use this skill 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

Safety Rules

1. Always confirm recipient and message content before sending
2. Never send to unknown numbers without explicit user approval
3. Be careful with attachments — confirm file path exists
4. Rate limit yourself — don't spam

Example Workflow

User: "Text mom that I'll be late"

# 1. Find mom's chat
imsg chats --limit 20 --json | jq '.[] | select(.displayName | contains("Mom"))'
 
# 2. Confirm with user
# "Found Mom at +1555123456. Send 'I'll be late' via iMessage?"
 
# 3. Send after confirmation
imsg send --to "+1555123456" --text "I'll be late"
