create_signup_sheet — Create sign-up sheet
Open-world
Creates a live online sign-up sheet on SignUpSheet.page where people claim slots from one shared link without an account, and returns the share link and the private organizer link. Use it when the user wants people to sign up for things: dishes for a potluck or class party, volunteer shifts, snack or carpool days, meal train dates, appointment or conference time slots, supplies to bring, classroom helpers. Each slot has a label, an optional date and start/end time, and how many people it needs; full slots get a waitlist and people get a reminder the day before. Not for voting on dates, group cards, ticket sales or paid registration.

Open-world
Creates a group scheduling poll on SignUpSheet.page: people open one link and answer yes, maybe or no for each date or time option, and the option that works for most people is highlighted. Returns the share link and the private organizer link, where the organizer can pick the final time and notify everyone who left an email. Use it when the user wants to find a date or time that works for a group, such as a meeting, dinner, reunion, parent night or study session. Not for sign-up slots or opinion polls without dates.

}create_group_card — Create group card
Open-world
Creates an online group card on SignUpSheet.page for one person: everyone opens one shared link and writes a message, and the organizer delivers the finished card later by email, on screen or printed. Use it for a farewell, birthday, retirement, thank-you, new baby, get well, sympathy, welcome, wedding, graduation, work anniversary or congratulations card from a team, class or family. It can also collect money for a gift (chip_in): signers pledge an amount and pay the organizer directly. Returns the share link (for signers, not for the recipient) and the private organizer link.

Reads the current public status of a SignUpSheet.page sign-up sheet, date poll or group card from its share link: which slots are open or full, poll answers per option, or how many people have signed a card. Use it when the user asks how their sheet, poll or card is going. Takes the public share link (signupsheet.page/s/…); it never returns email addresses or other private details.
