The tool permanently removes data (a NeoWiki Subject) from the wiki, which cannot be undone. This matches the Destructive category definition. Severity is high because deletion of wiki content affects data integrity and can impact collaborative work, though the blast radius is somewhat limited by the requirement for edit rights and NeoWiki-specific dependencies.

From the tool's definition Tool name explicitly includes 'delete' and description states 'Deletes one NeoWiki Subject by ID from its page.' This is an irreversible deletion operation.

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "neowiki-delete-subject"
  ]
}
