    Why it is in this group

    • 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
    Use this when the user wants to unscramble letters or find all words that can be made from a set of letters (word unscrambler, anagram solver, letter-tile word finder), optionally with blank tiles (? or *) and filters for length, starts with, ends with, or contains. Returns dictionary matches grouped by length with counts (every match is counted; up to 25 words are listed per length) and tile points (standard letter values, no board bonuses). Does not check board placement or define words. Do not use for crossword patterns with known letter positions (use solve_word_pattern).

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when the user plays a 5-letter word guessing game with green/yellow/gray feedback and wants the remaining possible answers or a strong next guess (word game solver, guess helper). Takes previous guesses with their color feedback (G/Y/-), applies the standard repeated-letter rules, counts the words still possible and lists up to 60 of them, and ranks next guesses by expected information. Supports 4-8 letter variants and hard mode. Does not know today's answer and does not play the game. Do not use for unscrambling letters or crossword patterns.

    • 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
    Use this when the user needs words that fit a pattern of known and unknown letters, such as a crossword answer (C?T, _A_E, 7 letters ending in ING), with optional letters that must or must not appear. Counts every matching dictionary word and lists up to 120 of them, common words first. Does not solve clues by meaning or look up definitions. Do not use for unscrambling a set of letters (use solve_anagram).

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.
