AI agents call ebay_delete_ad to permanently remove resources in Ebay — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes advertising content from an active campaign. While not directly financial, deletion of ads cannot be undone and represents loss of seller marketing investments and campaign configuration. This is irreversible data destruction, making it Destructive rather than Write.
From the tool's definition Tool name explicitly uses 'delete' and description states 'Delete a specific ad from a campaign' — this is an irreversible removal of marketing assets.
