Skill UI

This skill provides a structured framework for designing and implementing composable recommendation, ranking, and feed pipelines. It models the industry-standard six-stage pattern: Source, Hydrator, Filter, Scorer, Selector, and SideEffect. Use it for any system that selects "the top K items for a (user, context)", such as social feeds, ad ranking, RAG rerankers, or content recommendation engines, ensuring a robust and scalable architecture.

This guide helps researchers refine their academic work to meet the rigorous standards of top economics journals like JPE. It teaches users to move beyond simple correlation by structuring their research around clear economic mechanisms, linking evidence to established theory, ensuring generality, and properly considering equilibrium effects. Use this when developing a paper pitch or deciding the overall scope of a manuscript.
