What problem does it solve? Reviewing screens for usability problems is often ad hoc and inconsistent, causing teams to miss critical issues like poor error handling, weak feedback states, or dark patterns before release. ## Core Features & Use Cases - Heuristic Evaluation: Systematically checks screens against Nielsen's 10 usability heuristics, from system status visibility to error recovery. - Mobile UX Checks: Verifies touch target sizes, safe-area handling, skeleton loading, and gesture affordances specific to mobile interfaces. - Dark Pattern Detection: Flags manipulative patterns such as forced modals, exit-prevention dialogs, and unclear CTA labels. - Use Case: Before shipping a new checkout screen, run the audit to receive a graded score (A+ to F) with critical, major, and minor issues plus concrete code-level recommendations. ## Quick Start Ask the assistant to run a UX audit on a specific screen or page, for example by saying: audit the checkout screen for usability issues.
