Send and receive iMessages/SMS via the imsg CLI on macOS.
This skill helps you read and send iMessage and SMS messages through macOS Messages.app. It uses the command-line tool imsg to retrieve recent chats, conversation history, and attachment information. You can also watch a selected conversation for new messages.
It supports sending text and files to phone numbers or Apple IDs. For delivery, you can choose iMessage, SMS, or automatic selection.
Use it to check recent exchanges or review an earlier conversation before contacting someone. It also supports short messages to family members and messages with attachments such as images.
You need macOS, imsg, and a signed-in Messages.app. Your terminal also needs Full Disk Access and Automation permission to control Messages.app. The workflow requires confirming the recipient and message content before sending. Adding or removing group members is unsupported, and bulk messaging requires prior confirmation.
