Delete all WordPress transients (cached temporary data). Useful for clearing stale caches.
AI agents call wp_transient_delete_all to permanently remove resources in Wp Cli — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes all transient data across a WordPress installation. While transients are temporary by design, they often store important cached query results, API responses, and session data. Bulk deletion without recovery capability fits the Destructive category.
From the tool's definition Tool name explicitly states 'delete_all' and description confirms it 'Delete[s] all WordPress transients'. Transients are persistent cached data that cannot be easily recovered once deleted.
