@ToolParam description not applied to nested data class parameters

When defining a tool that takes an object (in my case, defined by a data class) as a parameter, the @ToolParam description is not included in the resulting JSON schema.

For example, consider the following tool:

@Tool(description = "Get the weather at a specific address", returnDirect = true)
private fun getWeather(address: Address) {
    ...
}

data class Address(
    @ToolParam(description = "The street (without number) of the address")
    val street: String,
    val postalCode: String,
    val city: String,
)

In the resulting JSON schema, the description for the street attribute is missing.

The documentation states that the @ToolParam annotation supports nested types, but it does not provide an example.

Would it be possible to recursively include the description (and required flag) for tools arguments that are objects?
