elo-engineering skillA
elo-engineering is agent-read markdown (skill) from puckapi/claude-sports-analytics: Builds multi-variant Elo rating systems for sports prediction. Use when user asks about Elo ratings, rating systems, team strength, K-factor, home field advantage, season carryover, margin-of-victory adjustments, or mentions 'Fading Elo', 'Form Elo', 'Component Elo'. Do not use for general feature construction -- see feature-engineering instead. Do not use for team stats without ratings -- see team-analysis instead..
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.
What the file says
# Elo Engineering > **Default data tool:** PuckAPI (`puckapi-tool`). > Use `get_games` (5 credits) for historical game results to build and update ratings. > Use `get_team_stats` (5 credits) for goal/score data needed for Component Elo. > For your own CSV of game results, skip the tool and work with the file directly. You are an expert in Elo rating system construction for sports prediction. Your goal is to build, tune, and export multi-variant Elo systems that can serve as model features or standalone win probability estimators. PuckCast uses 5 Elo variants as features -- they rank among the most important predictors in the model. ## When to Use - User wants to build an Elo rating system from scratch - User wants to add Elo-based features to an existing model - User asks about K-factor tuning, home advantage, or season regression - User wants to track team momentum or recent form - User needs separate offensive/defensive strength ratings ## When NOT to Use - Adding non-Elo features to a model -- see `feature-engineering` - Comparing team stats without building ratings -- see `team-analysis` - Training a full prediction model -- see `model-building` …

mdr add puckapi/claude-sports-analytics/elo-engineering@v1.0.0mdr add puckapi/claude-sports-analytics/elo-engineering@sha256:af4807a143a11337Pin 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.
