67%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 description excels at specificity and distinctiveness by listing concrete HPC techniques and targeting a clear C++20 niche. However, it lacks explicit trigger guidance ('Use when...') and could benefit from more natural user-facing keywords beyond technical jargon to help Claude recognize when users need this skill.
Suggestions
Add a 'Use when...' clause with trigger scenarios like 'Use when optimizing C++ performance, improving execution speed, or when user mentions vectorization, parallelism, or memory optimization'
Include natural language variations users might say: 'optimize', 'speed up', 'performance issues', 'slow code', 'make faster'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'cache-friendly data structures, SIMD vectorization, memory management, thread parallelism, lock-free data structures, and NUMA-aware allocation' - these are all concrete, specific HPC techniques. | 3 / 3 |
Completeness | Clearly answers 'what' with specific HPC patterns and techniques, but lacks an explicit 'Use when...' clause or trigger guidance. The 'when' is only implied by the domain context. | 2 / 3 |
Trigger Term Quality | Contains good technical keywords like 'SIMD', 'cache-friendly', 'lock-free', 'NUMA', 'C++20', but missing common user variations like 'performance optimization', 'fast code', 'optimize', 'speed up', or file extensions like '.cpp'. | 2 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche combining C++20 with specific HPC concepts (SIMD, NUMA, lock-free). Unlikely to conflict with general C++ skills or other language performance skills due to the specific technical focus. | 3 / 3 |
Total | 10 / 12 Passed |
Implementation
79%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a high-quality HPC reference skill with excellent, executable C++20 code examples covering cache optimization, SIMD, threading, and memory management. The content is appropriately concise and highly actionable. However, it functions more as a pattern catalog than a guided workflow, and the length could benefit from progressive disclosure into separate files for advanced topics.
Suggestions
Add a brief workflow section at the top outlining the optimization sequence (profile → identify bottleneck → select pattern → verify) with explicit validation steps
Consider splitting into SKILL.md (overview + cache/basic patterns) with links to SIMD.md, THREADING.md, LOCK_FREE.md, and NUMA.md for advanced topics
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, presenting code patterns directly without explaining basic C++ concepts or HPC fundamentals that Claude already knows. Every section jumps straight to executable examples. | 3 / 3 |
Actionability | All code examples are complete, executable C++20 with proper includes, templates, and memory management. The patterns are copy-paste ready with clear BAD/GOOD comparisons and practical usage examples. | 3 / 3 |
Workflow Clarity | The skill presents patterns as reference material rather than workflows. The 'Key Principles' section at the end provides a high-level sequence but lacks explicit validation checkpoints or feedback loops for verifying optimizations work correctly. | 2 / 3 |
Progressive Disclosure | Content is well-organized with clear section headers, but it's a monolithic document (~400 lines) that could benefit from splitting advanced topics (NUMA, lock-free structures) into separate reference files with links from a shorter overview. | 2 / 3 |
