Capabilities

Tools 3

create_signup_sheet

Use this when the user wants people to claim slots: potluck dishes, volunteer shifts, carpool seats, snack turns. It publishes a shared page where each person enters a first name and picks slots; each slot has a capacity and a full slot cannot be taken. Returns a public link to share and a private organizer link. Slots may have dates and times (then give an IANA time_zone). Does not send emails or reminders and does not take payments.

Discovered
show_signup_results

Use this when the user asks who signed up, what is still open, or how many spots are left on a sheet made with create_signup_sheet. Takes the private organizer link and returns each slot with its capacity, spots taken, open spots and names, plus people's notes. Does not work with the public link and does not change the sheet.

Discovered
update_signup_sheet

Use this when the organizer wants to change a sheet made with create_signup_sheet: add slots, change a slot's label or capacity, remove an empty slot, change the per-person limit, show or hide names, edit the note, or close and reopen sign-ups. Takes the organizer link and only the changes. A capacity cannot go below the people already signed up, and a slot with sign-ups cannot be removed. Does not notify participants.
