What problem does it solve? Manually auditing UI designs for usability issues is time-consuming and inconsistent, often missing common heuristic violations. This Skill provides a structured, checklist-driven review of any UI file, URL, or screenshot against Nielsen's 10 heuristics and a practical usability checklist. ## Core Features & Use Cases - Heuristic-Based Audit: Evaluates interfaces across 10 categories including system status visibility, error prevention, consistency, and accessibility contrast. - Prioritized Findings: Outputs issues classified as Critical, Warning, or Info, each paired with a concrete improvement suggestion, plus a Good section highlighting strengths. - Use Case: A designer shares a screenshot of a new checkout form. The Skill checks validation timing, button labeling, tap target spacing, and contrast ratios, then returns a prioritized fix list. ## Quick Start Ask the AI to run a design review on your UI screenshot or URL using the design-review checklist and return prioritized usability findings.
