Community Event Run of Show Builder (YAML)

AI Prompt

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

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

inputs:
  event_name: "${event_name:Riverside Neighborhood Book Swap and Picnic}"
  event_type: "${event_type:free outdoor community gathering}"
  date_and_hours: "${hours:Saturday, doors 11:00, end 15:00}"
  venue: "${venue:public park pavilion with two picnic areas and one power outlet}"
  expected_attendance: "${attendance:about 120 people including families with kids}"
  volunteers_available: "${volunteers:8 volunteers, 2 of them can arrive early for setup}"
  program_ideas: "${program:book swap tables, kids story corner, local author reading, raffle, potluck snacks}"
  budget: "${budget:300 USD}"
  constraints: "${constraints:no amplified sound after 14:30, park requires the area to be clean by 16:00}"

instructions:
  - Assume reasonable details where something is missing and list them under assumptions.
  - Use 24-hour times. Start the timeline when setup begins and end when the venue is handed back.
  - 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.
  - Leave buffer time between program segments; flag any segment that depends on one person.
  - Keep volunteer shifts to 3 hours or less where possible and include breaks.
  - Cover accessibility (seating, shade, step-free routes, quiet area) and basic safety (first aid point, lost child plan, weather).
  - Keep the budget realistic and show what to cut first if money runs short.
  - Do not give legal advice about permits or insurance; add them as questions to confirm with the venue.
