Annotation Interface LoopAgent

@Retention(RUNTIME) @Target(METHOD) public @interface LoopAgent
Marks a method as a definition of a loop agent, used to orchestrate the agentic workflow by invoking a series of sub-agents in a loop until a certain condition is met or a maximum number of iterations is reached. Each sub-agent is defined using the SubAgent annotation, which specifies the sub-agent's type and its output variable name.

Example: 


    public interface StyleReviewLoopAgentWithCounter {

        @LoopAgent(
                description = "Review the given story to ensure it aligns with the specified style",
                outputName = "story", maxIterations = 5,
                subAgents = {
                    @SubAgent(type = StyleScorer.class, outputName = "score"),
                    @SubAgent(type = StyleEditor.class, outputName = "story")
            }
        )
        String write(@V("story") String story);
    }
