      What this check looks for
    Description, as the server wrote it
    Use this when the user wants a crossword puzzle (crossword maker, crossword puzzle maker, crossword for a class or a vocabulary list) built from answers and clues. Builds a valid interlocking grid with standard numbering and Across/Down clue lists, reports any answers that could not be placed, shows a playable crossword, and returns a printable PDF with an answer key. Needs 4-40 answer-and-clue pairs; if the user gives only words, write a short clue for each first. Answers are reduced to letters A-Z. Does not solve existing crosswords or answer single clues, and does not make symmetric newspaper-style grids.

    Description, as the server wrote it
    Use this when the user wants a new sudoku puzzle to play or print (sudoku generator, printable sudoku with answers, easy sudoku for kids, hard sudoku). Generates a classic 9x9 sudoku at easy, medium or hard difficulty, checked by a solver for a single solution, playable in the chat with pencil notes, plus a printable PDF with the answer key. Does not solve a sudoku the user already has, explain solving strategies, or make 4x4, 6x6 or variant sudoku.

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.
