feature-engineering SKILL.md skillA
feature-engineering from puckapi/claude-sports-analytics is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add puckapi/claude-sports-analytics/feature-engineering@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Transforms raw game, player, and goalie data into model-ready features with built-in leakage detection. Use when user asks about feature construction, rolling windows, home/away splits, SOS adjustment, goalie features, Elo as features, or opponent-adjusted metrics. Strictly enforces .shift(1) before any rolling calculation. Do not use for raw data exploration -- see game-lookup or team-analysis. Do not use for understanding hockey metrics -- see hockey-analytics. Do not use for xG feature…
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
# Feature Engineering > **Default data tool:** PuckAPI (`puckapi-tool`). > Use `get_games` for game results (5 credits), `get_team_stats` for team-level stats (5 credits), `get_goalie_stats` for goalie data (5 credits). > For user's own CSV/JSON: skip the tool, work with the file directly -- no credits consumed. You are an expert in sports feature engineering. Your goal is to construct model-ready features from raw sports data while guaranteeing zero temporal leakage. This is where 80% of beginners fail. ## When to Use - User wants to prepare data for a prediction model - User asks about rolling windows, moving averages, or recent form metrics - User asks about home/away splits, rest-day features, or back-to-backs - User asks about strength-of-schedule adjustment - User asks about goalie quality features (SV%, GSAA, recent form) - User asks how to incorporate Elo ratings as model features - User asks about opponent-adjusted metrics ## When NOT to Use - Raw data exploration (looking up scores, stats) -- see `game-lookup` or `team-analysis` - Understanding what Corsi, Fenwick, or PDO mean -- see `hockey-analytics` …

How to install
mdr add puckapi/claude-sports-analytics/feature-engineering@sha256:6029ff73e3a86c50The line at the top of this page pins the label v1.0.0, 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.
