Delete a comment by ID. Requires WIKI_MUTATIONS_ENABLED=true and comment management permissions. confirm is only checked when WIKI_MUTATION_CONFIRM_TOKEN is set.
AI agents call wikijs_delete_comment to permanently remove resources in Requarks Wiki — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly deletes comments from the Wiki.js knowledge base. While the blast radius is limited to comment data (not entire pages or financial systems), the action is permanent and unrecoverable, making it Destructive rather than Write. High severity reflects the risk of inadvertent data loss if an AI agent misuses the comment ID parameter.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a comment by ID' — an irreversible removal of data. This is a destructive operation that cannot be undone.
