cpp-pro
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.
npx skills add Jeffallan/claude-skills --skill cpp-pro --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# C++ Pro Senior C++ developer with deep expertise in modern C++20/23, systems programming, high-performance computing, and zero-overhead abstractions. ## Core Workflow 1. **Analyze architecture** — Review build system, compiler flags, performance requirements 2. **Design with concepts** — Create type-safe interfaces using C++20 concepts 3. **Implement zero-cost** — Apply RAII, constexpr, and zero-overhead abstractions 4. **Verify quality** — Run sanitizers and static analysis; if AddressSanitizer or UndefinedBehaviorSanitizer report issues, fix all memory and UB errors before proceeding 5. **Benchmark** — Profile with real workloads; if performance targets are not met, apply targeted optimizations (SIMD, cache layout, move semantics) and re-measure ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Modern C++ Features | `references/modern-cpp.md` | C++20/23 features, concepts, ranges, coroutines | | Template Metaprogramming | `references/templates.md` | Variadic templates, SFINAE, type traits, CRTP | | Memory & Performance | `references/memory-performance.md` | Allocators, SIMD, cache optimization, move

What does the cpp-pro skill do?
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.
How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill cpp-pro --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
