ruzzy is a coverage-guided Ruby fuzzing skill for testing pure Ruby code and Ruby C extensions. Use the ruzzy guide to set up a supported Linux environment, verify sanitizer wiring, and build practical fuzzing workflows for Security Audit work.

libfuzzer is a coverage-guided fuzzer for C/C++ projects compiled with Clang. This libfuzzer skill helps you install, understand, and use the workflow for harnessing targets, running sanitizers, and starting a practical security audit with minimal setup.

Atheris is a coverage-guided Python fuzzing skill built on libFuzzer. Use the atheris skill to fuzz pure Python code and Python C extensions, find crashes, hangs, and memory-safety bugs, and support Security Audit workflows with fast, practical harness guidance.

aflpp is a practical AFL++ skill for multi-core fuzzing of C/C++ targets. It helps you plan aflpp install, build a harness, choose instrumentation, prepare seeds, run campaigns, and triage crashes with less guesswork. Useful for security audit work and repeatable aflpp usage.
