The description uses vague, abstract language like 'principles' and 'requirements' without listing any concrete actions. It doesn't specify what Claude actually does - no verbs describing capabilities.

The 'what' is extremely weak (just topic areas, not actions), and there is no 'when' clause or explicit trigger guidance. Missing any 'Use when...' statement entirely.

Contains relevant domain keywords 'VR/AR' that users might naturally say, but lacks common variations like 'virtual reality', 'augmented reality', 'XR', 'Oculus', 'Unity VR', or specific task-related terms.

VR/AR is a reasonably specific domain that wouldn't conflict with most skills, but the vague terms 'principles', 'interaction', and 'performance' could overlap with general game development or UI/UX skills.

Extremely lean and efficient use of tables to convey information. No unnecessary explanations of what VR/AR is or how it works - assumes Claude's competence and delivers only actionable specifications.

Provides concrete specifications (FPS targets, resolutions, frame budgets) and clear do/don't guidance, but lacks executable code examples. For a development skill, missing code snippets for implementing teleportation, hand tracking, or comfort settings reduces actionability.

Content is well-organized into logical sections but lacks explicit workflow sequences. No step-by-step process for implementing VR/AR features, no validation checkpoints for testing comfort or performance requirements.

Good internal organization with clear sections and tables, but no references to external files for deeper topics like platform-specific implementation guides, performance optimization techniques, or interaction pattern examples that would benefit from separate detailed documentation.
