Changes things 1Claude Code: ask
  • check_availabilityCheck whether a plan can be fulfilled right now for a given quantity, using the same gate the checkout runs.No findings

    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
    Check whether a plan can be fulfilled right now for a given quantity, using the same gate the checkout runs. Returns available true/false; reason 'delisted' means the SKU left the catalog, 'unavailable' means it temporarily cannot be fulfilled.

    • title: Check plan availability

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.
