About this skill

What it does. Installs Ruzzy with Clang, creates harnesses for pure Ruby code or native C extensions, and runs libFuzzer campaigns with corpus and crash-file support. It configures AddressSanitizer or UBSan to detect memory corruption and undefined behaviour.

When to use it. For fuzzing Ruby applications, libraries and gems with native extensions, especially when testing memory safety. Pure Ruby targets require a tracer script, while C and C++ targets should use a direct native fuzzer instead.
