Delete a wiki page. Cannot delete system pages (index.md, log.md, timeline.md).
AI agents call wiki_delete to permanently remove resources in Agent Wiki — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes wiki pages from the knowledge base. Although it has a safeguard against deleting certain system pages (index.md, log.md, timeline.md), it can still irreversibly delete user-created wiki content. Deletion is an irreversible operation that cannot be undone, making it Destructive rather than Write.
