## Why unlink_items is rated Critical

An AI agent that decides to call unlink_items doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Grabblist is gone. There is no undo for destructive operations.

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Grabblist:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "unlink_items"
  ]
}
```
