Delete all comments from a Jira ticket
AI agents call delete_all_comments to permanently remove resources in Jira — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes all comments associated with a ticket, which cannot be undone. This is an irreversible destructive action affecting potentially important discussion history and audit trails. The blast radius is high if an agent misuses it on critical tickets, though limited to a single ticket's comment data rather than the ticket itself or broader system data.
From the tool's definition Tool name contains 'delete_all_comments' and description states 'Delete all comments from a Jira ticket' — irreversibly removes data without individual confirmation or undo capability.
