What is infersports-skill?

InferSports Skill is a plugin for AI coding agents that gives them access to live football and basketball odds, scores, and probability estimates. Once installed, you can ask your agent plain-English questions like "anything worth watching today?" or "is this Polymarket price good value?" and get back a single concise line rather than a wall of JSON. It works with Claude Code, Codex, OpenClaw, and any agent that can run shell scripts. The skill pulls data from Asian bookmaker markets, which the README describes as sharper reference points than most Western odds. It covers Asian handicap, totals (over/under), and 1x2 (home/draw/away) markets for both full-time and half-time outcomes. One key feature is de-vigging: the skill strips out the bookmaker's built-in margin and reports a "fair" probability you can compare against other prices. If you see a prediction market offering 52% on a team the books imply is 55.6%, the compare command tells you that directly. The plugin exposes 12 commands. A few examples: today lists live and upcoming matches for the day, match returns the current score and favorite for a named game, fair gives the stripped-margin probability for any market, scan finds spots where a bookmaker's price beats the fair line by a set threshold, and convert translates between odds formats (decimal, Hong Kong, Malay, American, implied probability). Every command returns one line per item by default, with caps on how many results come back, which keeps the agent's context window from filling up. Installation requires no account and no API key. The one-line install uses a Claude Code plugin command or a single claude mcp add line for MCP users. Alternatively, a shell script is provided for other agents. The underlying API is a public service at api.infersports.dev. The README states the tool is read-only and never places, recommends, or sizes bets, and instructs the agent not to do so either.
