    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
    Looks up when a domain registration expires, over RDAP at the registry for its TLD. Subdomains are looked up by their registered domain (www.example.co.uk becomes example.co.uk).

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.
