SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit UX usability issues by auditing a project's user experience against established laws and Nielsen's heuristics. It focuses on behavioral outcomes — does the flow work? is the user confused? does the system communicate well?

Core Features & Use Cases

Category-based evaluation against classic UX laws (Hick's, Miller's, Tesler, Occam, Pareto) and Nielsen's heuristics, with severity tagging.
Actionable fixes: for each finding, provide recommended remedies and prioritization for the primary funnel.
Structured reporting: compile findings with file references to inform design decisions before launch or after UI changes.

Use Case: After designing a new flow, run ux-audit to surface friction points and improve usability.

Quick Start

Run /ux-audit to scan the project and surface UX issues with actionable fixes.

FAQPage Schema

How do I audit UX usability issues against established design principles?▼

Run a heuristic evaluation to surface UX usability issues by checking your project against established laws and Nielsen's heuristics. This identifies behavioral friction across navigation, cognition, feedback, and error handling to inform design decisions before launch or after UI changes.

What is a heuristic evaluation and when do I need it for my UI?▼

A heuristic evaluation is a behavioral assessment of a user interface against established UX laws and Nielsen's heuristics. You need this UX audit to surface friction points and improve usability after designing a new flow or making UI changes.

How do I prioritize actionable fixes for my primary user funnel?▼

You can prioritize actionable fixes for your primary funnel by using severity tagging from a UX audit. The evaluation scores usability issues and provides recommended remedies to inform design decisions and streamline the primary user flow.

Can I evaluate user experience without running live user testing?▼

Yes, you can evaluate user experience without live user testing by conducting a heuristic evaluation. This UX audit applies cognitive principles and laws of UX to identify usability issues and generate structured reporting with actionable fixes.

What UX laws and principles are used to evaluate interface usability?▼

Interface usability is evaluated using classic UX laws like Hick's, Miller's, Tesler, Occam, and Pareto, alongside Nielsen's heuristics. These cognitive principles assess navigation, feedback, and error handling to identify usability issues.

What format does a UX audit report use to document usability findings?▼

A UX audit report uses structured reporting to compile usability findings with file references and severity scores. This documentation provides actionable fixes and recommended remedies to inform design decisions before launch.
