Implements coverage-guided fuzz testing for C and C++ projects using the LLVM-integrated libFuzzer toolchain.
This skill provides a comprehensive framework and implementation patterns for using libFuzzer, an in-process, coverage-guided fuzzer built into the LLVM project. It enables developers to rapidly set up fuzzing harnesses, integrate with AddressSanitizer (ASan) and UndefinedBehaviorSanitizer (UBSan), and manage input corpora to identify critical memory safety vulnerabilities and edge-case bugs in C/C++ codebases. It is particularly effective for projects already using Clang and looking for a low-complexity entry point into automated security testing.
