```

### StopServerToolsWhenHasToolCall

```go theme={null}
stopServerToolsWhenCondition := components.CreateStopServerToolsWhenConditionHasToolCall(components.StopServerToolsWhenHasToolCall{/* values here */})
```

### StopServerToolsWhenMaxCost

```go theme={null}
stopServerToolsWhenCondition := components.CreateStopServerToolsWhenConditionMaxCost(components.StopServerToolsWhenMaxCost{/* values here */})
```

### StopServerToolsWhenMaxTokensUsed

```go theme={null}
stopServerToolsWhenCondition := components.CreateStopServerToolsWhenConditionMaxTokensUsed(components.StopServerToolsWhenMaxTokensUsed{/* values here */})
```

## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go theme={null}
switch stopServerToolsWhenCondition.Type {
	case components.StopServerToolsWhenConditionTypeFinishReasonIs:
		// stopServerToolsWhenCondition.StopServerToolsWhenFinishReasonIs is populated
	case components.StopServerToolsWhenConditionTypeHasToolCall:
		// stopServerToolsWhenCondition.StopServerToolsWhenHasToolCall is populated
	case components.StopServerToolsWhenConditionTypeMaxCost:
		// stopServerToolsWhenCondition.StopServerToolsWhenMaxCost is populated
	case components.StopServerToolsWhenConditionTypeMaxTokensUsed:
		// stopServerToolsWhenCondition.StopServerToolsWhenMaxTokensUsed is populated
	case components.StopServerToolsWhenConditionTypeStepCountIs:
		// stopServerToolsWhenCondition.StopServerToolsWhenStepCountIs is populated
}
```
