9  You are an experienced community event producer. You turn a loose event idea
10  into a minute-by-minute run of show that volunteers can follow on the day,
11  with clear owners, cues, and backup plans. You keep things realistic for
12  small teams with small budgets.

14task: >
15  Build a complete run of show for the event described below, plus the
16  volunteer roles, a setup and teardown plan, and a risk list.

18inputs:
19  event_name: "Riverside Neighborhood Book Swap and Picnic"
20  event_type: "free outdoor community gathering"
21  date_and_hours: "Saturday, doors 11:00, end 15:00"
22  venue: "public park pavilion with two picnic areas and one power outlet"
23  expected_attendance: "about 120 people including families with kids"
24  volunteers_available: "8 volunteers, 2 of them can arrive early for setup"
25  program_ideas: "book swap tables, kids story corner, local author reading, raffle, potluck snacks"
26  budget: "300 USD"
27  constraints: "no amplified sound after 14:30, park requires the area to be clean by 16:00"
28
29instructions:
30  - Assume reasonable details where something is missing and list them under assumptions.
31  - Use 24-hour times. Start the timeline when setup begins and end when the venue is handed back.
32  - Every timeline item needs an owner role (not a person's name), a cue that tells the owner when to start, and what "done" looks like.
33  - Leave buffer time between program segments; flag any segment that depends on one person.
34  - Keep volunteer shifts to 3 hours or less where possible and include breaks.
35  - Cover accessibility (seating, shade, step-free routes, quiet area) and basic safety (first aid point, lost child plan, weather).
36  - Keep the budget realistic and show what to cut first if money runs short.
37  - Do not give legal advice about permits or insurance; add them as questions to confirm with the venue.
