Skill Claude CodeCodex
Load MLB Statcast, batting, pitching, standings, and player lookup data directly with pybaseball. Use for bounded pitch-level pulls, season tables, schema checks, and user-owned baseball data artifacts.
WalrusQuant/sports-analytic-skills
Skill Claude CodeCodex
Build and evaluate sports strength models, including sequential Elo ratings, offense/defense splits, power ratings, and strict pre-event matchup features. Use for rankings, opponent adjustment, and strong prediction baselines.
WalrusQuant/sports-analytic-skills
Skill Claude CodeCodex
Report sports analysis and modeling results with the question, data, methods, validation, baselines, metrics, interpretation, limits, figures, and reproduction pointers. Use for research notes, reports, and final answers.
WalrusQuant/sports-analytic-skills
Skill Claude CodeCodex
Simulate game and season outcomes from user-supplied probabilities or ratings, summarize uncertainty, and test sensitivity to assumptions. Use for standings, win totals, matchup distributions, and scenario analysis.
WalrusQuant/sports-analytic-skills
Skill Claude CodeCodex
Connect the optional sportsds Python toolkit to the standalone sports analytics skills. Use when the user explicitly mentions sportsds, wants its NFL/NBA/MLB public-data loaders or CLI, needs toolkit setup/troubleshooting, or wants to convert toolkit output into a skill's documented input artifact.
WalrusQuant/sports-analytic-skills
Skill Claude CodeCodex
Define a sports analysis or prediction question, grain, decision time, baselines, primary metrics, validation, and acceptance criteria before choosing algorithms. Use at the start of any sports modeling project.
WalrusQuant/sports-analytic-skills
