create_list
ClaudeSaves list-shaped content as a ListDrop list the user can keep, check off, and share: an itinerary, a reading or watch list, a packing list, gift ideas, an apartment or job-search shortlist, a step-by-step plan, a checklist. Applies when the user wants a list to outlive the conversation. Not meant for throwaway answers, secrets or sensitive data (a list is unowned until claimed), or content that isn't list-shaped. Without a connected account the list is created private and unowned, and the result contains a secret claim URL: opening it is the only way to view and keep the list, and unclaimed lists are deleted after 30 days. With a connected ListDrop account (OAuth, lists:write) the list is created directly in that account, private, and the result contains its URL instead. A URL inside an item becomes a titled, linked item. Optional fields: allowed_emails shares the private list view-only with specific people, who open the returned share URL and verify their address with a one-time email link (no account needed); expires_in_days makes the list archive itself on a date, for trips and events.
