Names the domain (EARS methodology, requirements) and the general action (transform vague prompts into specifications), but doesn't list multiple concrete actions like 'parse requirements', 'generate EARS templates', or 'validate syntax'.

Clearly answers both what (transform vague prompts into precise specifications using EARS) and when (explicit triggers listed including 'optimize my prompt', 'improve this requirement', and contextual conditions like 'raw requirements lack detail').

Includes excellent natural trigger phrases users would say: 'optimize my prompt', 'improve this requirement', 'make this more specific', plus contextual triggers like 'loose requirements' and 'ambiguous feature descriptions'.

The EARS methodology provides some distinctiveness, but 'improve this requirement' and 'make this more specific' could overlap with general writing improvement or editing skills. The prompt optimization angle could conflict with other prompt engineering skills.

The skill is reasonably efficient but includes some unnecessary explanation (e.g., the methodology attribution paragraph, some redundant framing). The overview could be tighter, and some sections like 'Quality criteria' repeat concepts already implied by the framework.

Provides concrete, executable guidance with specific EARS patterns, transformation checklists, structured output templates, and real before/after examples. The six-step workflow is clear with specific actions at each step.

The six-step workflow is clearly sequenced with explicit phases, checklists, and structured output format. Each step has clear inputs/outputs and the transformation checklist provides validation checkpoints.

Excellent structure with a clear overview, well-organized main content, and clearly signaled one-level-deep references to four specific reference files. The 'When to load references' section provides clear navigation guidance.
