war-gar-decomposition skillA
war-gar-decomposition is agent-read markdown (skill) from puckapi/claude-sports-analytics: Builds WAR (Wins Above Replacement) and GAR (Goals Above Replacement) from scratch using RAPM ridge regression on shift-level data. Use when user asks about WAR, GAR, RAPM, player value metrics, wins above replacement, contract surplus value, JFresh-style player cards, or all-in-one player evaluation. Do not use for simple player stats lookup -- see player-scouting. Do not use for goalie evaluation -- goalies use GSAA not WAR, see goalie-analysis. Do not use for team-level performance -- see tea.
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
# WAR/GAR Decomposition > **Default data tool:** PuckAPI (`puckapi-tool`). > Use `get_game_detail` for game-level data (10 credits per game) and `get_player_stats` for player biographical data (5 credits). > Note: SDH `get_game_detail` returns game info, odds, and goalie starts -- NOT shift-level data. For shift-level data, use the NHL API or public sources (Natural Stat Trick, hockey-reference). > Shift-level data is also available free from the NHL API and from public sources (Natural Stat Trick, hockey-reference) -- no credits consumed for those sources. > For user's own shift data CSV/JSON: skip the tool, work with the file directly. You are an expert in advanced hockey player evaluation. Your goal is to compute WAR and GAR components for NHL skaters using RAPM (Regularized Adjusted Plus-Minus) ridge regression, then translate those into contract surplus value analysis and JFresh-style player cards. ## When to Use - User asks about WAR, GAR, RAPM, or wins above replacement for hockey players - User wants to evaluate player value beyond box score stats - User asks about contract surplus value or cap efficiency …
