164-java-profiling-verify
Use when you need to verify Java performance optimizations by comparing profiling results before and after refactoring — including baseline validation, post-refactoring report generation, quantitative before/after metrics comparison, side-by-side flamegraph analysis, regression detection, or creating profiling-comparison-analysis and profiling-final-results documentation.

Discovery
85%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, well-crafted description that clearly defines a specific niche (Java performance profiling comparison) with explicit trigger conditions and detailed capabilities. The main weakness is the reliance on technical jargon that users may not naturally use when requesting help, though the domain is inherently technical.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'baseline validation, post-refactoring report generation, quantitative before/after metrics comparison, side-by-side flamegraph analysis, regression detection, creating profiling-comparison-analysis and profiling-final-results documentation.' | 3 / 3 |
Completeness | Clearly answers both what (verify Java performance optimizations, compare profiling results, generate reports, detect regressions) and when ('Use when you need to verify Java performance optimizations by comparing profiling results before and after refactoring'). | 3 / 3 |
Trigger Term Quality | Contains relevant technical terms like 'profiling', 'flamegraph', 'refactoring', 'Java performance', but these are somewhat specialized. Missing common user variations like 'benchmark', 'speed test', 'performance test', or simpler terms users might naturally say. | 2 / 3 |
Distinctiveness Conflict Risk | Highly specific niche: Java performance profiling comparison with explicit focus on before/after refactoring analysis, flamegraphs, and specific documentation types. Unlikely to conflict with general Java or generic profiling skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
42%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides a reasonable high-level overview of the verification workflow but lacks actionable, executable guidance. The content is organized well with appropriate progressive disclosure to a reference file, but the main skill body offers no concrete commands, scripts, or specific profiler invocations that Claude could execute directly.
Suggestions
Add concrete executable examples: specific profiler commands for generating baseline vs post-refactoring reports (e.g., async-profiler or JFR commands)
Include a numbered workflow with explicit validation checkpoints, such as 'Verify baseline reports exist before proceeding to refactoring'
Provide a concrete comparison script or command example for metrics comparison rather than just describing what to compare
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content has some redundancy - the constraints section repeats information from the scope and 'What is covered' sections. The bullet lists are reasonably efficient but could be tighter. | 2 / 3 |
Actionability | No concrete code, commands, or executable examples provided. The skill describes what to do conceptually but lacks specific profiler commands, comparison scripts, or copy-paste ready instructions. | 1 / 3 |
Workflow Clarity | The workflow steps are implied (baseline → refactor → post-refactoring → compare → document) but not explicitly sequenced with numbered steps or validation checkpoints. Missing explicit 'validate before proceeding' gates. | 2 / 3 |
Progressive Disclosure | Appropriately structured as an overview with a clear single-level reference to detailed guidance in references/164-java-profiling-verify.md. Content is well-organized with clear sections. | 3 / 3 |
Total | 8 / 12 Passed |
