WHAT IT DOES

What group-delete-event does on Nostr Bray

AI agents call group-delete-event to permanently remove resources in Nostr Bray, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why group-delete-event is rated Critical

This tool permanently removes an event from a group, which cannot be undone. Although it requires a confirm flag (a safeguard), the core function is destructive — deletion with no recovery path. In a multi-agent system, accidental or malicious invocation could remove group content irreversibly. This is more severe than Write (which is reversible) and warrants Destructive classification.

From the tool's definition Tool name contains 'delete' and description states 'Administratively delete one event' — this is irreversible removal of data. Operates on a Nostr group (NIP-29) with administrative privilege.

RECOMMENDED RULE

The rule that runs group-delete-event safely

group-delete-event Hidden

group-delete-event is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
