From the source SKILL.md

Use this skill when C++ code shares mutable state across threads using standard primitives (std::thread, std::jthread, std::mutex, std::atomic, std::condition_variable, std::once_flag, thread_local) and the question is whether the synchronization is correct, deadlock-free, and shut down deterministically.
