Annotation Interface UserMessageProviderSupplier

@Retention(RUNTIME)
@Target(METHOD)
public @interface UserMessageProviderSupplier

Marks a method as a user message provider for an agent. The annotated method must be static, accept an Object parameter (the memoryId), and return a String (the user message).

This provides a declarative alternative to programmatically calling AgentBuilder.userMessageProvider(java.util.function.Function), and is useful when the user message needs to be dynamically computed at runtime.

Example:

    public interface DynamicAgent {

        @Agent("An agent with a dynamic user message")
        String chat(@V("request") String request);

        @UserMessageProviderSupplier
        static String userMessageProvider(Object memoryId) {
            return "Process the request for session " + memoryId;
        }
    }
