What problem does it solve? Identifying usability problems in apps, websites, and digital interfaces before user testing is time-consuming and often unsystematic. This Skill provides a structured expert evaluation framework based on Jakob Nielsen's 10 usability heuristics, producing prioritized, actionable findings without requiring a UX specialist on staff. ## Core Features & Use Cases - Systematic Heuristic Evaluation: Walks through all 10 Nielsen heuristics (visibility of system status, error prevention, consistency, and more) with concrete checklists and common violation patterns for each. - Severity-Rated Findings: Scores every issue on a 0-4 severity scale (cosmetic to catastrophic) and prioritizes fixes by impact on critical user tasks. - Structured Audit Report: Generates a complete report with executive summary, per-heuristic findings, quick wins, long-term improvements, and phased recommendations. - Use Case: Before launching a redesigned checkout flow, run this audit to catch issues like missing loading indicators, unclear error messages, or destructive actions without confirmation, then hand the prioritized fix list to your design and engineering teams. ## Quick Start Audit my app's onboarding flow using the Nielsen heuristics and produce a severity-rated report with prioritized recommendations.
