Why it matters

Architect and scaffold production-ready recommendation systems using the six-stage Source → Hydrator → Filter → Scorer → Selector → SideEffect framework to deliver personalized feeds, search results, and ranked content for any "top K items" use case.

Outcomes

What it gets done

01

Generate pipeline scaffolding for social feeds, content CMS, and notification triage systems

02

Implement multi-stage filtering and scoring logic for RAG rerankers and search results

03

Build composable ranking components following the xAI For You algorithm pattern

04

Configure selectors and side-effects for ad ranking, task prioritizers, and personalized recommendations

Install

Add it to your toolbox

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.

Run in your project directory:

curl -fsSL https://spark.entire.vc/get/ag-recsys-pipeline-architect | bash

After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview

Recsys Pipeline Architect

A spec-and-scaffold skill for building composable recommendation, ranking, and feed pipelines. It encodes the six-stage Source-Hydrator-Filter-Scorer-Selector-SideEffect framework popularized by xAI's open-sourced For You algorithm. This is an independent reimplementation of the pattern under MIT license for building "top K items for a (user, context)" systems across social feeds, content CMSs, RAG rerankers, task prioritizers, notification triage, search reranking, and ad ranking. Use this when you need the six-stage Source-Hydrator-Filter-Scorer-Selector-SideEffect framework for social feeds, content CMSs, RAG rerankers, task prioritizers, notification triage, search reranking, or ad ranking. It's a spec-and-scaffold skill that encodes the pattern from xAI's For You algorithm as an independent reimplementation.

What it does

This is a spec-and-scaffold skill for building composable recommendation, ranking, and feed pipelines. It encodes the six-stage Source → Hydrator → Filter → Scorer → Selector → SideEffect framework popularized by xAI's open-sourced For You algorithm. This skill is an independent reimplementation of the pattern under MIT license. Use it whenever you need "the top K items for a (user, context)" across social feeds, content CMSs, RAG rerankers, task prioritizers, notification triage, search reranking, or ad ranking.

When to use - and when NOT to

Use this skill when you need the six-stage Source-Hydrator-Filter-Scorer-Selector-SideEffect framework for building recommendation, ranking, and feed pipelines. It's designed for use cases that fit the "top K items for a (user, context)" pattern: social feeds, content CMSs, RAG rerankers, task prioritizers, notification triage, search reranking, and ad ranking.

Do NOT use this when you need a pre-built, production-ready recommendation system out of the box - this is a spec-and-scaffold tool. Avoid this skill if your use case doesn't fit the "top K items for a context" pattern, such as simple filtering or single-item lookups without ranking.

Who it's for

This skill is for anyone building recommendation, ranking, and feed pipelines who wants to use the six-stage framework pattern from xAI's For You algorithm. It's an independent reimplementation of the pattern (no code copied from the original) under MIT license.
