Schedule a text to one contact for a date and time.

SimpleTexting API: https://cotlet.dev/docs/api/simpletexting.md

`POST https://cotlet.dev/api/v1/simpletexting/message/schedule`

Access: write. Confirm: waits for the user's OK before it runs.

Does what the Clock icon in the Inbox does: the text goes to one contact at the time you give. Returns the scheduled message id. SimpleTexting does not let you edit a scheduled message, so a change means deleting it in the app (three dots, delete) and scheduling a new one. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `contact_phone` | string | yes | Phone number of the contact, with country code. |
| `text` | string | yes | Message text. |
| `send_at` | datetime | yes | When to send, ISO 8601 with offset. |
