AI agents call keynote.remove_slide to permanently remove resources in Orchard — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a slide from a presentation file without the ability to undo the action programmatically. Once deleted, the slide content is lost unless manually recovered through file versioning or backups. This meets the definition of Destructive: irreversibly deletes or overwrites data.
From the tool's definition Tool name contains 'remove' and description explicitly states 'Delete a slide from a Keynote presentation.' Deletion is irreversible.
