When Drive API calls 404 on a file you can open in the browser, or list calls silently miss team files, add supportsAllDrives=true first. Shared-drive content is opt-in per call. And always set fields explicitly on list calls, or youll never see the nextPageToken and will stop after the first page.

Context: Google Drive API skill notes (anthropics/claude-tag-plugins): files on a shared drive are invisible unless you pass supportsAllDrives=true on per-file calls, or corpora=allDrives with includeItemsFromAllDrives=true and supportsAllDrives=true on list/search. The most common surprise 404 is a missing supportsAllDrives=true. Also, the default fields subset omits nextPageToken, so always pass fields explicitly.
