Writes, optimizes, and debugs C++ applications using modern C++20/23 features, template metaprogramming, and high-performance systems techniques. Use when building or refactoring C++ code requiring concepts, ranges, coroutines, SIMD optimization, or careful memory management — or when addressing performance bottlenecks, concurrency issues, and build system configuration with CMake.

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 an excellent skill description that hits all the key criteria. It uses third person voice, provides specific concrete actions, includes comprehensive trigger terms that developers would naturally use, and has an explicit 'Use when' clause with detailed scenarios. The description clearly carves out a distinct niche for modern C++ development.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Writes, optimizes, and debugs C++ applications' with detailed technical capabilities including 'template metaprogramming', 'SIMD optimization', 'memory management', 'concurrency issues', and 'CMake' configuration. | 3 / 3 |
Completeness | Clearly answers both what ('Writes, optimizes, and debugs C++ applications using modern features...') AND when ('Use when building or refactoring C++ code requiring concepts, ranges, coroutines...'). Includes explicit 'Use when' clause with specific trigger scenarios. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'C++', 'C++20/23', 'concepts', 'ranges', 'coroutines', 'SIMD', 'memory management', 'performance bottlenecks', 'concurrency', 'CMake'. These are terms developers naturally use when seeking C++ help. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear C++ focus and specific modern C++ features (C++20/23, concepts, ranges, coroutines). The combination of language-specific terms and advanced techniques creates a clear niche unlikely to conflict with general programming or other language skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that demonstrates excellent token efficiency while providing comprehensive, actionable guidance for C++ development. The workflow includes proper validation checkpoints with explicit feedback loops, and the progressive disclosure through the reference table is exemplary. The code examples are executable and demonstrate real patterns rather than pseudocode.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, avoiding explanations of concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context about what C++ is or how compilers work. | 3 / 3 |
Actionability | Provides fully executable code examples for concepts, RAII wrappers, and smart pointers. The constraints are specific and actionable (exact compiler flags, specific tools to run), and code is copy-paste ready. | 3 / 3 |
Workflow Clarity | The 5-step core workflow includes explicit validation checkpoints with feedback loops: 'if AddressSanitizer or UndefinedBehaviorSanitizer report issues, fix all memory and UB errors before proceeding' and 'if performance targets are not met... re-measure.' This properly gates progression on validation. | 3 / 3 |
Progressive Disclosure | Excellent structure with a clear overview, reference table pointing to one-level-deep topic files with 'Load When' guidance, and well-organized sections. The reference guide table makes navigation intuitive and context-aware. | 3 / 3 |
Total | 12 / 12 Passed |
