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 well-crafted skill description that clearly defines its capabilities, provides explicit trigger guidance, and occupies a distinct niche. It uses third person voice correctly, includes both a 'Use when' clause and explicit trigger phrases, and covers natural user language variations. The description is concise without being vague.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Calculate NFT rarity scores', 'rank tokens by trait uniqueness'. These are clear, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (calculate rarity scores, rank tokens by trait uniqueness) and 'when' (explicit 'Use when' clause plus a 'Trigger with phrases' section listing specific triggers). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms: 'check NFT rarity', 'analyze collection', 'rank tokens', 'compare NFTs', 'NFT collections', 'token rarity'. These are phrases users would naturally say. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche focused on NFT rarity scoring and token ranking. Unlikely to conflict with other skills given the specific domain of NFT trait analysis. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides strong actionability with concrete, executable commands and good progressive disclosure through external references. However, it lacks validation checkpoints in its workflow (e.g., verifying API responses, checking export integrity) and has some conciseness issues with sections that restate what the commands already convey. The algorithm table and supported collections section add useful but somewhat verbose context.
Suggestions
Add validation steps after key operations, e.g., verify the collection was fetched successfully before exporting, or check token count matches expectations after analysis.
Trim the Overview bullet list since the numbered command sections already demonstrate each capability, and condense the 'Supported Collections' section into a single line.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient with clear command examples, but includes some unnecessary sections like 'Supported Collections' criteria and the algorithm table descriptions that add moderate bloat. The overview bullet list restates what the commands already demonstrate. | 2 / 3 |
Actionability | Provides fully executable bash commands for every operation with concrete collection names and token IDs. Options are clearly enumerated with flags and descriptions. Commands are copy-paste ready. | 3 / 3 |
Workflow Clarity | Steps are clearly listed and sequenced, but there are no validation checkpoints or feedback loops. For operations involving API calls, caching, and data export, there's no guidance on verifying results, handling partial failures, or confirming output correctness. | 2 / 3 |
Progressive Disclosure | Well-structured with a concise overview, clear command sections, and appropriate references to external files (errors.md, examples.md) that are one level deep and clearly signaled with descriptive bullet points. | 3 / 3 |
Total | 10 / 12 Passed |
