What problem does it solve? Free technical events routinely see 40-60% of registrants never show up, leaving organizers guessing how many registrations to accept, how to run a waitlist, and what headcount to give catering. This Skill turns those guesses into a defensible capacity plan with sourced show-up rates and explicit arithmetic. ## Core Features & Use Cases - Overbooking ceilings: Sets a registration ceiling against the room's hard capacity using the sourced ~50% free-event show-up trendline (never above double aimed attendance), or your own measured rate from a prior edition. - Waitlist and walk-in design: Chooses FIFO versus proximity-prioritized waitlist ordering with a published rule and drain date, and wires a day-of walk-in lane with expected volume. - Catering handoff: Hands the expected-show-up number (never the registration count) to budget planning, with the overbooking buffer stated separately. - Use Case: You have 400 registrations for a free hackathon in a 250-seat room. The Skill shows the ceiling arithmetic, confirms whether to close the form, and gives catering the expected attendance figure with the buffer named. ## Quick Start Ask the Skill how many registrations to accept for your free event given your room capacity, and what headcount to send the caterer.
