The prompt
The exact prompt that built this app. Give it to your agent to build the app from scratch with Elements, or use it to compare what other tools make from the same ask.
Build a planning poker app named sizingdeck for sprint estimation. - Create a room and share its link. Join with just a name. - The facilitator adds stories to estimate (title and a link). - Everyone picks a card (1, 2, 3, 5, 8, 13, 21, ?, coffee) face down; you see who has voted but not what. - The facilitator reveals: cards flip, with the average and the spread, and the room agrees on a final estimate. - A list of estimated stories, exportable as CSV. Seed one room with five named participants and a few stories already estimated. Joining, voting and reveals happen in real time for everyone in the room.
