Attachment Threads

Why Attachments Are Different

When a message includes a file attachment (image, document, etc.), Smithy handles it differently from a regular text message. The original message stays in the channel because it contains the uploaded file. Deleting it would remove the file for everyone.

How It Works

When someone posts a message with a file attachment in a Thread Mode channel:

1. The original message (with the file) stays in the channel
2. Smithy posts a control message as a reply to the original message
3. The control message contains the thread content, tags, and action buttons

No Authorization Needed

Since the original message is preserved (not deleted), Attachment Threads do not require user authorization for message cleanup. Smithy works entirely with its own bot permissions to manage the thread replies.
