# Governance

> See how Gateway rules affect tools in an external Agent.

The SDK reports the Agent's tools to GroundForge. An administrator can then assign one action to each discovered tool: **Allow**, **Observe**, **Review**, or **Block**.

Using the demo Agent:

```text theme={null}
User asks: What is the weather in Ottawa?
Agent selects: get_weather(city="Ottawa")
GroundForge checks: the rule for get_weather
```

| Action  | What the user sees                                    | Does `get_weather` run?                       |
| ------- | ----------------------------------------------------- | --------------------------------------------- |
| Allow   | Normal Agent response                                 | Yes                                           |
| Observe | Normal Agent response                                 | Yes, with a highlighted decision in the Trace |
| Review  | A configured review message while an operator decides | Only after approval                           |
| Block   | A configured policy response                          | No                                            |

## How the SDK applies the decision

1. The Channel request reaches the running external Agent.
2. The Agent selects `get_weather`.
3. The SDK checks the Gateway decision before calling the original Python function.
4. Allow and Observe continue immediately. Review creates an Operator Task. Block stops the call.
5. The result and decision are included in the request Trace.

For Review, an operator opens **Operator Tasks** in GroundForge and approves or rejects the exact requested call. A rejection does not call the tool.

For a Block test, open the Trace and confirm that `get_weather` is marked as not executed and has no tool output.

## Example

Set `get_weather` to Review, send the same weather question, and verify the tool does not run until the Operator Task is approved. Follow [Request Review](/guides/request-review) for the exact steps.
