7%This description is severely underdeveloped, essentially serving as a placeholder rather than a functional skill description. It provides no information about what the skill actually does, relying entirely on the skill name to convey meaning. The redundant trigger terms and missing 'Use when' clause make it nearly useless for skill selection among multiple options.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Splits test suites across multiple workers, configures parallel execution strategies, and optimizes test distribution for faster CI/CD pipelines'
Include a 'Use when...' clause with natural trigger terms like 'run tests in parallel', 'speed up test suite', 'concurrent test execution', 'distribute tests', 'pytest-xdist', 'parallel CI'
Remove the redundant trigger term and replace with diverse variations users might actually say when needing this functionality
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the skill ('Test Parallelizer') and mentions 'Test Automation' but provides no concrete actions. There's no explanation of what the skill actually does - no verbs describing capabilities like 'splits tests', 'distributes workloads', or 'optimizes execution'. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name itself, and the 'when' guidance is essentially non-existent - just repeating the skill name as a trigger. There's no explicit 'Use when...' clause or meaningful trigger guidance. | 1 / 3 |
Trigger Term Quality | The trigger terms listed are just 'test parallelizer' repeated twice, which is redundant and unlikely to match natural user language. Missing common variations like 'parallel tests', 'run tests in parallel', 'speed up tests', 'concurrent testing', or 'distribute test execution'. | 1 / 3 |
Distinctiveness Conflict Risk | While 'Test Parallelizer' is a specific concept that wouldn't conflict with most skills, the lack of detail means it could overlap with other test automation skills. The category mention 'Test Automation' is too broad to provide clear differentiation. | 2 / 3 |

Implementation
7%This skill is essentially a placeholder with no actionable content. It describes what test parallelization assistance would look like but provides zero actual guidance on how to parallelize tests - no code examples, no tool configurations (Jest, pytest), no strategies for handling shared state or test isolation. The entire content could be replaced with actual implementation guidance.
Suggestions
Add concrete code examples showing test parallelization configuration for specific frameworks (e.g., Jest's `--maxWorkers`, pytest-xdist's `-n auto`)
Include a workflow for identifying parallelizable tests and handling shared state/database isolation
Provide specific guidance on common pitfalls like race conditions, port conflicts, and test interdependencies
Remove the generic 'Capabilities' and 'Example Triggers' sections and replace with actual technical content
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is padded with generic boilerplate that provides no actual value. Phrases like 'provides automated assistance' and 'follows industry best practices' are vague filler that Claude doesn't need. | 1 / 3 |
Actionability | No concrete code, commands, or specific guidance is provided. The skill describes what it does abstractly but never shows how to actually parallelize tests - no examples, no configuration snippets, no tool-specific instructions. | 1 / 3 |
Workflow Clarity | No workflow is defined at all. There are no steps, no sequence, and no validation checkpoints for implementing test parallelization. The content only describes when the skill activates, not how to accomplish anything. | 1 / 3 |
Progressive Disclosure | The content is organized into clear sections with headers, but there's no actual content to disclose. References to related skills exist but no links to detailed documentation or examples are provided. | 2 / 3 |
