    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 you want to explain a five-field cron expression, find its next runs in an IANA timezone, or inspect daylight-saving transitions. Supports numeric *, lists, ascending ranges, and steps. Requires an explicit timestamp reference. Searches up to 1,830 days and returns up to 20 runs strictly after it. Does not execute jobs or support names, macros, seconds, years, ?, L, W, or #.

    Annotations the server declares

    • title: Explore cron schedule
    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

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.
