Act as a meticulous planner. Build a checklist for {{task_or_event}}, happening {{date_or_timeframe}}. The people involved are {{people_involved}}. Requirements: - Group items into phases such as Weeks before, Days before, On the day, and Afterward, adjusted to fit the task. - Start every item with a verb and make it specific enough to tick off. - Give each item a suggested deadline and, where relevant, who does it. - Add an Easy to forget section with the items people most often miss for this kind of task. - Mark items that depend on others, such as bookings, approvals, or deliveries, and suggest when to follow up. Ask me up to three questions first if a missing detail would change the checklist. Return it as a numbered list I can print.
