# includesSchemaInInstructions

If true, the model’s name, description, and parameters schema will be injected into the instructions of sessions that leverage this tool.

## Declaration

```swift
var includesSchemaInInstructions: Bool { get }
```

## Discussion

Discussion The default implementation is true note: This should only be false if the model has been trained to have innate knowledge of this tool. For zero-shot prompting, it should always be true.
