Publish a Note with a link card
publish_note_with_linkPublish a Substack Note with an attached link that appears as a preview card. Requires explicit confirmation because the post goes live publicly immediately.
Instructions
Publish a Note with a link attached, which renders as a preview card rather than a bare URL. Live and public immediately, so it refuses to run without confirm: true.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The URL to attach as a card. | |
| text | Yes | The Note's text, shown above the card. | |
| confirm | No | Must be true for this to run. This action cannot be undone, so it is refused without an explicit confirmation. | |
| publication | No | Which connected publication to act on, matched loosely against its hostname (for example 'example.substack.com' or just 'example'). Defaults to the first connected publication. |
