Why smartlead_update_email_account_tag needs a policy

This tool modifies email account tags/labels, which is a typical Write operation: it creates or updates data reversibly. The change is non-destructive (tags can be updated again), has no financial impact, and does not execute code or delete data. The low severity reflects the limited blast radius — worst case is organizational confusion or mistagged accounts, easily correctable.

From the tool's definition Tool name and description indicate it 'Update[s] the tag/label for an email account' — a reversible modification operation that changes metadata/organizational attributes without affecting core functionality or data integrity.

  "default": "deny",
  "tools": {
    "smartlead_update_email_account_tag": {
      "limits": [
        {
          "counter": "smartlead_update_email_account_tag_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
