RECOMMENDED RULE

The rule that runs preview_deletion safely

preview_deletion Allowed

preview_deletion is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "tools": {
    "preview_deletion": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every preview_deletion call is checked against it from then on.
