FunctionTool

@Serializable

class FunctionTool(val name: String, val description: String? = null, val parameters: JsonObject? = null) : ResponseTool

A function the model may call, described by its JSON Schema.

The model answers with a FunctionCallItem; run the function and feed the result back as a FunctionCallOutputItem carrying the same call_id.

Example:

val weather = FunctionTool(
    name = "get_weather",
    description = "Get the current weather for a city",
    parameters = buildJsonObject {
        put("type", "object")
        putJsonObject("properties") { putJsonObject("city") { put("type", "string") } }
        putJsonArray("required") { add("city") }
    },
)
