Cpp Pro

This is a focused C++20 skill that leans into modern language features like concepts, modules, ranges, and coroutines. It's aimed at performance-critical work: game engines, embedded systems, system software, SIMD optimization, and the kind of low-level coding where memory safety and resource management actually matter. The skill also covers template metaprogramming and migrating legacy codebases to modern standards. With 122 installs and clean security audits across three platforms, it's got some traction. If you're doing serious C++ work beyond basic CRUD apps, this gives Claude the context to talk shop about cache optimization and lock-free programming instead of fumbling with outdated patterns.
