AI agents call noteplan_manage_note to permanently remove resources in Noteplan — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool supports delete operations on notes, which is irreversible data loss. Per the severity rules, Destructive takes precedence over Write/Execute. Misuse by an AI agent could result in permanent deletion of notes/tasks. Severity is high given the blast radius across potentially many notes in a note management system.
From the tool's definition Manage notes: create, update, delete, move, restore, rename, or manage frontmatter properties — explicitly includes 'delete' action
