Permanently deletes a comment owned by the authenticated channel. This action is irreversible. Args - \
AI agents call youtube_delete_comment to permanently remove resources in Youtube — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data (a comment) and cannot be restored. While the blast radius is limited to a single comment rather than large-scale data, the permanent nature of deletion and the lack of recovery mechanisms places it in the Destructive category.
From the tool's definition Tool description explicitly states 'Permanently deletes a comment' and 'This action is irreversible.' The verb 'delete' combined with 'irreversible' indicates destructive action that cannot be undone.
