What problem does it solve? Interfaces often confuse users through unclear labels, hidden navigation, poor error messages, and manipulative patterns, and teams lack a structured method to find and prioritize these issues before users abandon tasks. ## Core Features & Use Cases - Heuristic Evaluation Framework: Audit interfaces against Krug's usability laws and Nielsen's 10 heuristics, with a 0-4 severity rating scale and a 10-point scoring diagnostic. - Structured Audit Template: Run per-screen evaluations with checklists for each heuristic, task-based testing, and the Trunk Test for navigation orientation. - Specialized References: Cover dark pattern recognition, WCAG 2.1 AA accessibility checks, cultural/RTL design considerations, and heuristic conflict resolution. - Use Case: When users report that a checkout flow is confusing, run a heuristic audit to identify that the form lacks inline validation and progress indicators, rate each issue by severity, and produce a prioritized fix list. ## Quick Start Audit this checkout page for usability issues using Nielsen's heuristics and give me a severity-rated list of fixes.
