recommendation-algorithm-design skillA

recommendation-algorithm-design is agent-read markdown (skill) from nirholas/three.ws: Complete mastery guide for designing social media recommendation algorithms — understanding candidate generation, ranking models, engagement prediction, content graph modeling, collaborative filtering, embedding spaces, real-time personalization, exploration vs exploitation tradeoffs, feedback loops, filter bubble mitigation, and building recommendation systems from scratch. Based on analysis of production systems like Twitter/X's open-source algorithm, with applications to crypto community feed.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add nirholas/three.ws/recommendation-algorithm-design@git:20260501.87cefc9
Exact content
mdr add nirholas/three.ws/recommendation-algorithm-design@sha256:d02f10d9edbe8055

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
