# recsys-pipeline-architect A spec-and-scaffold skill for building composable recommendation, ranking, and feed pipelines. It encodes the **six-stage pattern** — Source → Hydrator → Filter → Scorer → Selector → SideEffect — popularized by xAI's open-sourced [For You algorithm](https://github.com/xai-org/x-algorithm) (Apache 2.0). This skill is an independent reimplementation of the pattern (MIT) — no code copied from the original. Upstream: <https://github.com/mturac/recsys-pipeline-architect> ## When to Use - User wants to build any system that picks "the top K items for a user/context" - User asks "how should I rank X" or describes a feed/personalization problem - User has a scoring function and needs the pipeline plumbing around it - User wants to migrate from a single relevance score to multi-action prediction with tunable weights - User is wrapping an LLM/ML scorer and needs filters, hydrators, side-effects, and a runnable scaffold in their stack (TypeScript / Go / Python) - Triggers: "recommendation system", "feed algorithm", "ranking pipeline", "for you feed", "candidate pipeline", "content recommender", "pipeline architecture for recsys", "RAG retrieval reranker" …
