Quality
Discovery
82%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 description excels at specificity and trigger terms, naming concrete technologies (Supertest, httpx, pytest) and specific testing domains (REST, GraphQL, authentication). The main weakness is the absence of an explicit 'Use when...' clause, which would help Claude know exactly when to select this skill over others.
Suggestions
Add a 'Use when...' clause with trigger phrases like 'Use when testing HTTP endpoints, writing API tests, or when the user mentions Supertest, httpx, or API validation.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Test REST APIs, GraphQL, request/response validation, authentication, and error handling' along with specific tools (Supertest, httpx, pytest). | 3 / 3 |
Completeness | Clearly answers 'what' (HTTP API testing with specific tools and capabilities) but lacks an explicit 'Use when...' clause or equivalent trigger guidance, capping this at 2 per rubric guidelines. | 2 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'HTTP', 'API testing', 'REST APIs', 'GraphQL', 'authentication', 'TypeScript', 'Python', plus specific library names that developers would mention. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on HTTP API testing with named frameworks (Supertest, httpx, pytest); unlikely to conflict with general testing or other API skills due to specific technology stack mentions. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, actionable skill with excellent code examples covering both TypeScript/Supertest and Python/httpx patterns. The content is concise and well-organized, though it could benefit from explicit workflow guidance around test suite setup and database reset patterns that are mentioned but not demonstrated.
Suggestions
Add a brief workflow section showing the sequence: setup fixtures → run tests → validate results → cleanup, especially for database-dependent tests
Expand the 'Reset database between tests' best practice with a concrete example showing beforeEach/afterEach or pytest fixture patterns
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, jumping directly into installation and executable code examples without explaining what APIs are or how HTTP works. Every section provides actionable code without unnecessary preamble. | 3 / 3 |
Actionability | All code examples are complete, executable, and copy-paste ready. The TypeScript and Python examples include proper imports, realistic test scenarios, and cover common patterns like authentication, file uploads, and error handling. | 3 / 3 |
Workflow Clarity | While individual test patterns are clear, there's no explicit workflow for setting up a test suite from scratch, no validation checkpoints for test execution, and no guidance on test ordering or database reset sequences mentioned in best practices but not demonstrated. | 2 / 3 |
Progressive Disclosure | Content is well-organized with clear section headers, appropriate inline examples, and 'See Also' references to related skills. The structure allows quick navigation between TypeScript and Python approaches without requiring external files for this scope. | 3 / 3 |
