What Flaim Fantasy does

Flaim connects ChatGPT to a user's ESPN, Yahoo, and Sleeper fantasy leagues so ChatGPT can answer questions about current leagues, standings, rosters, matchups, drafts and draft-pick ownership, available players, player search, recent league moves, league info, and past seasons using the user's actual league context. Ten of its eleven tools are read-only. The eleventh, refresh_leagues, is a bounded write that re-discovers leagues through the user's connected accounts and updates only Flaim's own connected-league registry. Flaim never makes trades, adds or drops players, edits lineups, or modifies league data on ESPN, Yahoo, or Sleeper. This application uses fantasy data provided by Yahoo Fantasy.
