Only reads 1Claude Code: allow
  • get_standingsThe current table (rank, wins, losses, set percentage) plus the single most useful match to play next.No findings

    Why it is in this group

    • The name "get_standings" says "get": a word for reading.
    Description, as the server wrote it
    The current table (rank, wins, losses, set percentage) plus the single most useful match to play next. Standings are computed with a fixed rule order, so the same results always give the same table.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
