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 a specific niche (Java performance optimization verification via profiling comparison), lists concrete actions, provides explicit trigger guidance with natural user phrases, and is highly distinctive. The description is well-structured with both a 'Use when' clause and explicit trigger examples, making it easy for Claude to select appropriately.
| 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 verification through profiling comparison before/after refactoring. The specific focus on profiling-comparison-analysis documentation, flamegraph analysis, and regression detection makes it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill provides reasonable structure and workflow sequencing for a verification task, but critically lacks actionable, executable guidance — no commands, no code, no concrete tool invocations. It relies almost entirely on a reference file for actual instructions while repeating high-level concepts (identical test conditions, documentation requirements) across multiple sections. The content would benefit significantly from including at least minimal concrete commands and validation criteria inline.
Suggestions
Add concrete, executable commands for each workflow step (e.g., specific profiler invocation commands, file validation checks like `test -s profiler/reports/baseline-*.json`)
Include a concrete example of what a comparison output or metrics table should look like, so Claude knows the expected output format
Consolidate the redundant descriptions of constraints — the intro paragraph, 'What is covered', and 'Constraints' sections all repeat identical test conditions and documentation requirements
Add explicit pass/fail criteria and a feedback loop (e.g., 'If regression detected >5% in any metric, flag as failure and document root cause before proceeding')
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill has some redundancy — the introductory paragraph, 'What is covered' section, and 'Constraints' section repeat similar information (identical test conditions, documentation, validation). The 'When to use this skill' section lists near-duplicate triggers. However, it's not excessively verbose and doesn't explain concepts Claude already knows. | 2 / 3 |
Actionability | The skill provides no concrete commands, code snippets, or executable examples. Workflow steps are abstract directions like 'Run profiling with identical load/test conditions' without specifying actual tools, commands, or scripts to execute. Nearly all actionable detail is deferred to the reference file. | 1 / 3 |
Workflow Clarity | The four workflow steps are logically sequenced and include a validation concept (verify baseline exists, compare metrics), but lack explicit validation checkpoints with concrete commands, feedback loops for error recovery, or specific criteria for pass/fail. The instruction to 'verify baseline artifacts exist and are non-empty' is mentioned but not operationalized. | 2 / 3 |
Progressive Disclosure | The skill references a single deeper file (references/164-java-profiling-verify.md) which is appropriate one-level-deep disclosure. However, since no bundle files were provided, we can't verify the reference exists. The main issue is that the SKILL.md itself contains too little actionable content — it's almost entirely an overview with nearly all substance deferred to the reference, making the skill body itself insufficient to act on. | 2 / 3 |
