Why api_ultrade_market_order_message needs a policy

The tool appears to only generate a message from order data, which is a data transformation/formatting operation rather than actually placing or executing an order. However, in a DeFi context, 'market order message' could be a precursor to a financial transaction. The description is vague and does not confirm any side effects, money movement, or execution.

How to control api_ultrade_market_order_message

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "api_ultrade_market_order_message": {
      "limits": [
        {
          "counter": "api_ultrade_market_order_message_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
