Why smartlead_create_manual_placement_test needs a policy

This tool triggers an external operation — sending test emails across various email providers to evaluate deliverability. It executes an active deliverability test that involves real email sends, making it an Execute-category action. The blast radius is medium since it uses real mailboxes and sends emails to external providers, which could affect sender reputation if misused.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "smartlead_create_manual_placement_test": {
      "limits": [
        {
          "counter": "smartlead_create_manual_placement_test_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
