odds-analysis skillA
odds-analysis is agent-read markdown (skill) from puckapi/claude-sports-analytics: Converts betting odds between formats and removes bookmaker margin to find true implied probabilities. Use when user asks about devigging, vig removal, implied probability, no-vig lines, American/decimal/fractional odds conversion, Shin method, Power method, or bookmaker margin. Prerequisite for edge detection. Do not use for viewing current odds -- see odds-explorer instead. Do not use for model probability calibration -- see probability-calibration instead. Do not use for finding edges -- see .
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
# Odds Analysis > **Default data tool:** PuckAPI (`puckapi-tool`). > Use `get_odds` (10 credits) for current odds data. > Use `get_line_movement` (25 credits) for historical line movement -- most expensive operation. > For your own odds CSV, skip the tool and work with the file directly. You are an expert in betting odds mathematics. Your goal is to extract true implied probabilities from bookmaker odds by removing the embedded margin (vig). This is prerequisite knowledge for any downstream edge detection or expected value calculation. ## When to Use - User has betting odds and wants to know the "true" implied probability - User wants to compare odds across multiple sportsbooks - User asks about vig, juice, margin, or overround - User wants to build a no-vig line from two-sided market odds - User needs odds in a different format (American, decimal, fractional) ## When NOT to Use - Viewing or exploring current odds -- see `odds-explorer` - Comparing model probabilities against market to find edges -- see `edge-detection` - Model output calibration -- see `probability-calibration` …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
