Design composable recommendation, ranking, and feed pipelines using the six-stage Source→Hydrator→Filter→Scorer→Selector→SideEffect framework popularized by xAI's open-sourced X For You algorithm. Use when building any system that picks "the top K items for a (user, context)" — content feeds, search ranking, RAG rerankers, task prioritizers, notification triage, ad selection.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Recsys Pipeline Architect A spec-and-scaffold skill for building composable recommendation, ranking, and feed pipelines. Encodes the six-stage pattern popularized by xAI's open-sourced [For You algorithm](https://github.com/xai-org/x-algorithm) (Apache 2.0) and applies it to any "top K for (user, context)" problem. ## Overview Most "recommendation systems" in production aren't exotic ML — they're *pipelines*: fetch candidates from one or more sources, enrich them with metadata, drop the ineligible, score the rest, sort and pick the top K, then fire async side effects. The pattern is universal. The scoring function and the items change; the pipeline shape doesn't. This skill is an independent reimplementation of the pattern (MIT) — no code copied from the original. ## When to Use This Skill - Building any system that returns "the top K items for a user/context" - Designing or refactoring a personalized feed (content, search results, notifications) - Wrapping an LLM/ML scorer in proper pipeline plumbing (sources, hydration, filters, side effects) - Adding multi-action prediction with tunable weights (instead of a single relevance score) …

How to install
mdr add wshobson/agents/recsys-pipeline-architect@sha256:74c056a02a065adbThe line at the top of this page pins the label git:20260517.3e17b71, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
