## Why kb_delete_document is rated Critical

Deletion of documents cannot be undone and permanently removes information from the knowledge base. This is a destructive operation that warrants the highest severity category. While blast radius depends on the document's importance and scope, unauthorized deletion could cause significant harm to the organization's knowledge management system.

From the tool's own definition: "Tool name 'kb_delete_document' with description 'Delete a knowledge-base document'—the verb 'Delete' combined with operation on persistent data (knowledge-base document) indicates irreversible data destruction."

## Use case

AI agents call kb_delete_document to permanently remove resources in Munin, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
