# Prompt Before / After: Anonymized Real Run

This file shows representative prompt changes from the real office overtime tea-bar machine run. The examples are shortened and anonymized for public release.

## U1: Opening Pain And Product Introduction

| Before | After | Why it improved |
|---|---|---|
| Timeline includes sitting at desk, empty cup, turning to product, walking to product, picking up a glass, and waiting for water | Clip only establishes late-night office thirst and moves attention to the appliance; the user stops beside the product without starting the water action | Removes premature auto-fill behavior and avoids complex hand/cup action in the opening |
| Environment and product are described globally | Environment anchor controls office layout and product position; product images control appliance identity; person reference controls appearance only | Reduces reference contamination |
| Ending is a natural transition to the next Unit | `Stop when` the appliance is stable in the wall position and the user has arrived beside it | Makes the generated clip easier to evaluate and continue |
