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 excels across all dimensions. It provides specific implementation methods (URL paths, headers, query parameters), includes natural developer terminology, and has an explicit 'Use when' clause with clear trigger scenarios. The description is concise yet comprehensive, making it easy for Claude to select this skill appropriately.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Implements API versioning using URL paths, headers, or query parameters' and includes 'backward compatibility and deprecation strategies' - these are concrete, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what (implements API versioning with specific methods and strategies) AND when (explicit 'Use when' clause covering 'managing multiple API versions, planning breaking changes, or designing migration paths'). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'API versioning', 'URL paths', 'headers', 'query parameters', 'breaking changes', 'migration paths', 'multiple API versions' - good coverage of terms developers naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on API versioning with distinct triggers like 'versioning', 'breaking changes', 'migration paths' - unlikely to conflict with general API design or other development skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
79%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-crafted skill that efficiently covers API versioning strategies with concrete, executable code examples and useful comparison tables. The deprecation timeline and safe/breaking changes sections provide valuable guidance. However, it could benefit from explicit validation steps for testing version compatibility and better progressive disclosure for detailed migration guides.
Suggestions
Add a validation/testing section with steps to verify version compatibility (e.g., 'Test both versions with same request, compare responses')
Link to separate files for detailed migration guides and extended code examples mentioned in best practices
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Content is lean and efficient with well-organized tables, minimal prose, and code examples that demonstrate concepts without unnecessary explanation. No padding or concepts Claude already knows. | 3 / 3 |
Actionability | Provides fully executable JavaScript code for routing, version adapters, and deprecation headers. The comparison table and safe/breaking changes list give concrete, actionable guidance. | 3 / 3 |
Workflow Clarity | The deprecation timeline table provides a clear sequence, but lacks explicit validation checkpoints or feedback loops for the versioning implementation process itself. No guidance on testing version compatibility. | 2 / 3 |
Progressive Disclosure | Content is well-structured with clear sections and tables, but everything is inline. Migration guides and code examples mentioned in best practices could be linked to separate files for complex implementations. | 2 / 3 |
Total | 10 / 12 Passed |
