Names the domain (UX research) and some actions like 'user behavior analysis, usability testing, and data-driven design insights,' but these are more like category labels than concrete specific actions. It doesn't list discrete tasks like 'create usability test plans, analyze heatmaps, synthesize interview transcripts.'

Describes what it does at a high level but completely lacks any 'Use when...' clause or explicit trigger guidance. There is no indication of when Claude should select this skill. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and since the 'what' is also somewhat vague, this scores a 1.

Includes some relevant keywords like 'usability testing,' 'user behavior analysis,' and 'design insights,' but misses many natural user phrases such as 'user research,' 'UX audit,' 'user interviews,' 'survey analysis,' 'persona creation,' 'A/B testing,' or 'user journey mapping.'

The UX research domain is somewhat specific, but phrases like 'data-driven design insights' and 'improve product usability and user satisfaction' are broad enough to overlap with general product management, design, or analytics skills.

Extremely verbose at ~300+ lines. Extensively explains concepts Claude already knows (what UX research is, what personas are, what usability testing involves). Sections like 'Your Identity & Memory', 'Learning & Memory', 'Pattern Recognition', 'Success Metrics', and 'Advanced Capabilities' are largely filler that don't add actionable value. The personality/identity framing wastes significant tokens.

Provides structured templates (persona, usability testing protocol, research findings) which are somewhat actionable as fill-in-the-blank frameworks. However, there is no executable code, no concrete tool commands, and the workflow steps are vague (e.g., 'Define research questions and objectives' in a bash comment block). The templates are useful but are essentially structured placeholders rather than copy-paste ready artifacts.

The 4-step workflow (Planning → Collection → Analysis → Recommendations) provides a clear sequence, but steps are described at a high level without validation checkpoints or feedback loops. There's no guidance on what to do when research yields inconclusive results, insufficient sample sizes, or conflicting data. The usability testing protocol has better structure but still lacks explicit validation steps.

Monolithic wall of text with everything inline. Multiple large templates (study plan, persona, usability protocol, research findings) are all embedded in the main file, making it extremely long. No references to separate files for detailed templates or methodology guides. The final line references 'core training' which is vague and unhelpful. Content would benefit enormously from splitting templates into separate referenced files.
