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 defines its purpose, provides explicit trigger guidance with natural user phrases, and occupies a distinct niche. It names specific sources, concrete actions, and includes both 'Use when' and 'Trigger with' clauses, making it easy for Claude to select appropriately. The third-person voice is used correctly throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists concrete actions: aggregate breaking news, monitor market news, track announcements, find coin-specific updates. Specifies 50+ sources and names specific ones (CoinDesk, CoinTelegraph, The Block, Decrypt). | 3 / 3 |
Completeness | Clearly answers both 'what' (aggregate breaking cryptocurrency news from 50+ sources) and 'when' (explicit 'Use when' clause for monitoring, tracking, finding updates, plus explicit trigger phrases). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural user phrases: 'get crypto news', 'latest Bitcoin headlines', 'DeFi announcements', 'scan for breaking news', 'check crypto updates', plus terms like 'crypto market news', 'coin-specific updates', and 'announcements'. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche focused specifically on cryptocurrency news aggregation. The domain-specific terms (crypto, Bitcoin, DeFi, CoinDesk) and the specific use case make it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill with strong actionability — concrete CLI commands, clear output format, and good reference organization. Its main weaknesses are some content redundancy between the Instructions and Examples sections, and a lack of validation checkpoints in the workflow (e.g., checking script execution success before presenting results). The progressive disclosure is well done with clear pointers to supporting files.
Suggestions
Remove or consolidate the Examples section since most commands duplicate those already in the Instructions section — keep only the unique ones (--min-score, --coins) as additional examples inline.
Add a validation step after running the aggregator, e.g., checking exit code or verifying output before presenting results to the user.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Generally efficient but has some redundancy — the Examples section largely duplicates the commands already shown in the Instructions section. The output example with the 2026 date comment is slightly noisy. The error handling table is useful but could be more compact. | 2 / 3 |
Actionability | Provides fully concrete, copy-paste ready CLI commands with clear flag combinations for different use cases. The output format is explicitly shown, and the step-by-step instructions clearly tell Claude what to do at each stage. | 3 / 3 |
Workflow Clarity | The four-step workflow (assess intent → run aggregator → export → present) is clearly sequenced, but there are no validation checkpoints between steps. There's no feedback loop for verifying the script ran successfully before presenting results, and no explicit check that the output file was created before downstream processing. | 2 / 3 |
Progressive Disclosure | The SKILL.md serves as a clear overview with well-signaled one-level-deep references to implementation details, error handling, examples, and config files. The main content is appropriately concise with deeper material delegated to reference files. | 3 / 3 |
