Adapt to a changed brief

Purpose

Learn how the model responds when an important requirement changes during a task.

What you need

• A task with several clear requirements.
• A requirement change that affects the main approach.

Prompt

Initial instruction

Design a paid desktop product for expert users. Include the product structure, main screen, and launch plan.

Later requirement change

The product must now be free, mobile-first, and suitable for first-time users. Update the work. Keep only decisions that still apply.

What to observe

• Does the model identify which earlier decisions no longer apply?
• Does it update the full solution instead of adding a note?
• Does it preserve useful work from the first response?
• Does it explain important changes?
