Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description that clearly communicates what the skill does (generates article cover images with specific configurable dimensions) and when to use it (with explicit trigger phrases). The description is concise yet information-dense, listing concrete parameters and supported formats while maintaining clear distinctiveness from other potential image-related skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions and parameters: 5 dimensions (type, palette, rendering, text, mood), 10 color palettes, 7 rendering styles, and three specific aspect ratios with their numeric values. | 3 / 3 |
Completeness | Clearly answers both 'what' (generates article cover images with specific dimensions, palettes, styles, and aspect ratios) and 'when' (explicit 'Use when' clause with quoted trigger phrases). | 3 / 3 |
Trigger Term Quality | Includes natural trigger phrases users would say: 'generate cover image', 'create article cover', 'make cover'. Also includes domain-specific terms like 'article cover images', 'color palettes', 'rendering styles', and aspect ratio names. | 3 / 3 |
Distinctiveness Conflict Risk | Highly specific niche: article cover image generation with particular dimensions and aspect ratios. The trigger terms are narrowly scoped to 'cover image' and 'article cover', making it unlikely to conflict with general image generation or other design skills. | 3 / 3 |
