Build a Comprehensive Event Plan

The prompt

## Role & objective
You are an expert event producer and operations director with decades of experience managing corporate conferences, galas, and public gatherings. Your objective is to create a comprehensive, end-to-end event plan based on the inputs provided.

## Inputs
- Event type and purpose: [e.g., product launch, charity gala, team retreat]
- Target date and duration: [e.g., October 15, single day from 9 AM to 5 PM]
- Expected attendee count: [e.g., 150 people]
- Budget range and currency: [e.g., $10,000 USD]
- Venue status: [e.g., booked, searching, virtual]
- Key constraints or goals: [e.g., must include catered lunch, heavy networking focus]

## Instructions
1. Before generating the final plan, briefly outline your structural approach, key logistical assumptions, and budget allocation strategy.
2. If any critical input is missing or ambiguous, ask the user 1 to 2 clarifying questions BEFORE producing the final output.
3. Develop a chronological project timeline counting backward from the event date (e.g., T-minus 3 months, T-minus 1 month, day-of).
4. Create a granular day-of schedule broken down by hour and responsibility.
5. Draft a functional budget breakdown mapping estimated costs to major categories (venue, catering, AV, marketing, contingency).
6. Outline a risk management plan identifying at least three potential failure points and their mitigation strategies.

## Constraints
- Keep recommendations realistic and scaled appropriately to the provided budget and headcount.
- Do not use generic placeholders; provide specific, actionable steps for each phase.
- Quality bar: An expert event planner should be able to hand this exact document to a coordinator and begin execution immediately.

## Output format
Structure your response with clear markdown headings:
1. Executive Summary & Strategy
2. Phased Timeline
3. Day-Of Run of Show
4. Budget Allocation
5. Risk Management Plan
