Why apikeys_rotate_api_key is rated Critical
This tool irreversibly revokes an API key and replaces it. Although a new key is issued, the old one is destroyed and cannot be recovered, making this a destructive operation. The high severity reflects the blast radius: a misapplied rotation could lock out legitimate integrations relying on the revoked key, causing service disruption.
From the tool's definition 'Revoke the current API key' — the tool permanently invalidates the existing credential. 'DESTRUCTIVE — requires human confirmation' — the tool itself is labeled destructive.
