Annotation Interface SystemMessage

@Target({TYPE,METHOD}) @Retention(RUNTIME) public @interface SystemMessage
Specifies either a complete system message (prompt) or a system message template to be used each time an AI service is invoked.
An example: 
interface Assistant {

    @SystemMessage("You are a helpful assistant")
    String chat(String userMessage);
}
The system message can contain template variables, which will be resolved with values from method parameters annotated with @V.
An example: 
interface Assistant {

    @SystemMessage("You are a {{characteristic}} assistant")
    String chat(@UserMessage String userMessage, @V("characteristic") String characteristic);
}
When both @SystemMessage and AiServices.systemMessageProvider(Function) are configured, @SystemMessage takes precedence.
