SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Complex, data-dense interfaces like Carbon ACX can overwhelm users, leading to frustration and inefficiency. This skill provides expert UX evaluation, identifying usability issues and offering actionable recommendations to simplify interfaces and improve user experience.

Core Features & Use Cases

Heuristic Evaluation: Assesses interfaces against established usability principles (e.g., Nielsen's 10 heuristics).
Cognitive Walkthroughs: Simulates user tasks to identify learnability issues for new users.
User Journey Mapping: Visualizes the end-to-end user experience, highlighting pain points and opportunities.
Use Case: A product manager feels the "activity browser" is too cluttered. They ask, "Evaluate the UX of the activity browser," and receive a detailed report with prioritized findings and specific recommendations to reduce cognitive load and improve navigation, so "AI works, you rest."

Quick Start

Example: Activity Browser Heuristic Evaluation

User Request: "Evaluate the activity browser - it feels overwhelming"

Output:

# Activity Browser UX Evaluation

Date: 2025-10-22

Methodology: Heuristic Evaluation (Nielsen + Domain Heuristics)

Evaluator: Claude (acx.ux.evaluator)

## Executive Summary

The activity browser violates progressive disclosure principles by showing all 50+ parameters simultaneously. Users report feeling overwhelmed and unable to find basic actions.

FAQPage Schema

How do I evaluate usability issues in a data-dense interface?▼

Usability evaluation identifies friction points through heuristic analysis, cognitive walkthroughs, and user journey mapping. This Skill applies established principles like Nielsen's heuristics and progressive disclosure to assess interfaces—such as activity browsers or data-entry forms—surface pain points, and deliver prioritized recommendations with specific remedies to reduce cognitive load.

What's the difference between heuristic evaluation and cognitive walkthroughs?▼

Heuristic evaluation assesses an interface against usability principles to spot violations; cognitive walkthrough simulates how new users learn a task to find learnability barriers. This Skill uses both: heuristics catch design violations quickly, walkthroughs reveal where users get stuck during onboarding or complex workflows.

Can I get a UX evaluation report with severity ratings and specific file references?▼

Yes. This Skill delivers Markdown reports with executive summaries, detailed findings tagged by severity, exact file:line references for implementation, and prioritized recommendations. Output includes methodology, actionable next steps, and guidance for both quick wins and long-term interface improvements.

Does this work for React web apps, dashboards, and static sites?▼

Yes. This Skill evaluates UX across multiple Carbon ACX interface types: React web applications, Dash analytics dashboards, and static sites. It covers heuristic analysis, information architecture, progressive disclosure, and navigation workflows across onboarding, data entry, reporting, and emission features.

When should I use user journey mapping instead of heuristic evaluation?▼

Use user journey mapping to visualize end-to-end experiences and pinpoint pain points across workflows; use heuristic evaluation for rapid interface compliance checks. This Skill applies journey mapping when you need to understand how users navigate complex multi-step processes like emissions workflows or reporting pipelines.

What does the skill output tell me about information architecture problems?▼

Information architecture analysis within this Skill identifies structural issues—unclear navigation, poor categorization, or cognitive overload from too many simultaneous options. The report surfaces these problems with severity ratings and recommends reorganization, progressive disclosure, or hierarchical restructuring to improve discoverability and task flow.
