    Why it is in this group

    • The description's first verb is "run": a word for a change.
    Description, as the server wrote it
    Run a TrueSpin certified draw on NameWheel: the winner is sealed by NameWheel's server before it is revealed, randomness from this connection is added, and the result is published on a permanent public proof page (namewheel.org/v/CODE) that anyone can check, with a button that recomputes the draw. Use it when the result must be provable to other people: a class prize, a team decision, a draw announced to a group. IMPORTANT: the title, every entry and the winner become public on the proof page, so only use names the person is happy to publish, and tell them so. Needs a connected NameWheel account (free). To draw against a list locked earlier with freeze_list, pass frozen_code instead of entries.

    Why it is in this group

    Description, as the server wrote it
    Say what this NameWheel connection can do: without an account (spins, teams, wheel links, checking draws) or with a connected account (certified draws, frozen lists, the account's draws), and how many certified draws are left today. Use it when the person asks about limits, their account, or why a request was refused.

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • freeze_listLock a list of entries in public before a draw, at namewheel.org/f/CODE, with a fingerprint and the exact time.No findings

    Why it is in this group

    • The name "freeze_list" says "list": a word for reading.
    • The description's first verb is "lock": a word for a change.
    Description, as the server wrote it
    Lock a list of entries in public before a draw, at namewheel.org/f/CODE, with a fingerprint and the exact time. Nobody can add or remove a name after that, and when certified_draw later uses this list (frozen_code), the frozen page links to the result. Use it when entries close before the draw happens. The title and every entry are public. Needs a connected NameWheel account (free).

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Split a list of names into random teams or groups of even size, and show them as cards in the chat. Use it for class groups, project teams, game sides, rotations. Give either how many teams or how many people per team. Works without an account.

    Annotations the server declares

    • readOnlyHint: true

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Pick one or more winners at random from a list of names or options, and show the wheel spinning to the result in the chat. Use it whenever the person wants something chosen at random: a student to answer, who goes first, where to eat, a raffle winner among friends. Works without an account. The pick is fair (a cryptographic random number generator), but it is not a certified record; when other people need to be able to check the result later, use certified_draw instead.

      What this check looks for
    Description, as the server wrote it
    Check whether a NameWheel certified draw is genuine, from its code or its namewheel.org/v/ link: recomputes the winner from the published secret, the added randomness and the entries, checks the commitment made before the spin, and checks NameWheel's Ed25519 signature on the record. Also says how many draws the host ran on this exact list. Use it when someone asks whether a draw or a giveaway result was real. Works without an account.

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.
