Evidence version design-critique-strict-v2 · Agent compose-1.0.0 · Evaluated
Landing-page hierarchy
A responsive product landing page has a vague headline, competing calls to action, and weak visual hierarchy.
What a strong result needed- Finds the highest-impact hierarchy issue
- Connects critique to user comprehension
- Proposes one feasible revision
Cross-channel consistency
A launch set uses inconsistent color, type, and tone across web, email, and social assets.
What a strong result needed- Separates system issues from isolated taste
- Prioritizes corrections by visible impact
- Preserves the recognizable brand signal
Accessible interaction state
An important selected state relies on color alone and becomes unclear at narrow browser widths.
What a strong result needed- Identifies the accessibility failure
- Provides a non-color state cue
- Keeps the narrow layout usable
