Implementation
77%This is a solid, actionable skill with excellent executable code examples covering various utility testing scenarios. The main weakness is verbosity - it includes sections explaining concepts Claude already knows (when to use, best practices, common pitfalls) and could be more concise by moving detailed examples to separate files while keeping the core patterns in the main skill.
Suggestions
Remove or significantly trim the 'When to Use This Skill' section - Claude can infer appropriate usage from the skill title and examples
Consolidate 'Best Practices' and 'Common Pitfalls' into a brief checklist or remove entirely - these are standard testing knowledge
Consider moving detailed examples (Collection Utilities, String Transformations, Data Validation) to a separate EXAMPLES.md file, keeping only 2-3 core patterns in the main skill
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is moderately efficient but includes some unnecessary content like the 'When to Use This Skill' section that lists obvious use cases Claude would infer, and the Best Practices/Common Pitfalls sections contain guidance Claude already knows about testing. | 2 / 3 |
Actionability | Excellent executable code examples throughout - all Java test code is copy-paste ready with proper imports, annotations, and assertions. Covers multiple utility testing scenarios with concrete, working examples. | 3 / 3 |
Workflow Clarity | For a skill about unit testing utilities (which is inherently a single-step task per test), the workflow is clear. Tests are organized by category with clear patterns, and the structure guides from basic to advanced scenarios logically. | 3 / 3 |
Progressive Disclosure | Content is well-organized with clear section headers, but the skill is quite long (~300 lines) and could benefit from splitting detailed examples into separate reference files. The external references at the end are appropriate but the main content is somewhat monolithic. | 2 / 3 |

Activation
67%The description adequately covers both what the skill does and when to use it, with an explicit 'Use when' clause. However, it lacks specific concrete actions beyond 'test' and could benefit from more natural trigger terms that users would actually say. The domain is reasonably distinct but could be more precisely scoped to avoid overlap with other testing skills.
Suggestions
Add more specific concrete actions like 'validate input/output behavior', 'test edge cases', 'verify error handling' to improve specificity.
Include additional natural trigger terms users might say: 'utils', 'helpers', 'test my utility function', 'static method testing', or file patterns like '*Utils.java', '*Helper.ts'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (utility/helper classes, static methods, pure functions) and the general action (test), but doesn't list multiple specific concrete actions like 'mock dependencies', 'assert return values', or 'test edge cases'. | 2 / 3 |
Completeness | Clearly answers both what ('Unit tests for utility/helper classes and static methods. Test pure functions and helper logic') and when ('Use when validating utility code correctness') with an explicit trigger clause. | 3 / 3 |
Trigger Term Quality | Includes some relevant terms like 'utility', 'helper', 'static methods', 'pure functions', but misses common variations users might say like 'utils', 'helpers', 'unit test', 'test helpers', or specific file patterns. | 2 / 3 |
Distinctiveness Conflict Risk | Somewhat specific to utility/helper testing, but could overlap with general unit testing skills or other testing-related skills since 'utility code' and 'helper logic' are broad categories that might conflict with component or integration testing skills. | 2 / 3 |
Total | 9 / 12 Passed |
