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. This should trigger for requests such as Verify performance fix; Verify the performance; Verify the memory; Verify the threading. Part of cursor-rules-java project

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 strong skill description that clearly defines its niche in Java performance profiling verification. It excels at listing concrete actions, providing natural trigger terms users would say, and explicitly stating both what the skill does and when to use it. The description is well-structured and distinctive enough to avoid conflicts with other skills.
| 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, and creating specific documentation types. | 3 / 3 |
Completeness | Clearly answers both 'what' (verify Java performance optimizations by comparing profiling results, generating reports, flamegraph analysis, regression detection) and 'when' (explicit 'Use when' clause at the start plus 'This should trigger for requests such as...' with concrete examples). | 3 / 3 |
Trigger Term Quality | Includes strong natural trigger terms users would say: 'verify performance fix', 'verify the performance', 'verify the memory', 'verify the threading', plus domain terms like 'profiling', 'flamegraph', 'regression detection', and 'refactoring'. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche: Java performance profiling verification with before/after comparison. The specific focus on profiling comparison, flamegraph analysis, and regression detection makes it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
20%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill suffers from significant redundancy—the same concepts (identical test conditions, validate reports, document findings) are repeated across multiple sections without adding new information. The content is entirely abstract with no concrete commands, code examples, or tool invocations, deferring all actionable detail to a reference file. While the workflow sequence is logical, the lack of executable guidance and excessive repetition significantly reduce its effectiveness.
Suggestions
Remove redundant sections ('What is covered' largely duplicates the opening paragraph and workflow) and consolidate constraints into the workflow steps where they apply.
Add concrete, executable commands for each workflow step—e.g., the actual profiler command to run, specific file paths to check, and example comparison output.
Add explicit validation checkpoints in the workflow, such as 'Verify post-refactoring reports are non-empty before proceeding to comparison' with a specific check command.
Remove the 'When to use this skill' section as it duplicates frontmatter trigger information and wastes tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Significant redundancy throughout: the opening paragraph, 'What is covered' section, 'Constraints' section, and 'Workflow' section all repeat the same information (identical test conditions, document findings, validate reports). The 'When to use this skill' list is also redundant with frontmatter triggers. Much of this content explains things Claude can infer. | 1 / 3 |
Actionability | No concrete commands, code snippets, or executable examples are provided. The workflow steps are abstract descriptions ('Run profiling with identical load/test conditions') rather than specific commands or tool invocations. All actual guidance is deferred to the reference file. | 1 / 3 |
Workflow Clarity | The four workflow steps provide a reasonable sequence, and there is mention of validating that baseline artifacts exist before proceeding. However, there are no explicit validation checkpoints between steps (e.g., verify post-refactoring reports before comparison), no error recovery/feedback loops, and the steps lack specificity about what tools to run or what constitutes a valid result. | 2 / 3 |
Progressive Disclosure | There is a single reference file clearly linked at the bottom, which is good one-level-deep disclosure. However, the SKILL.md itself contains too much redundant inline content that could be trimmed, and without the bundle file available to verify, we can only confirm the reference path exists. The structure is reasonable but the inline content bloat undermines the disclosure pattern. | 2 / 3 |
