About this skill

What it does. Builds LibAFL fuzzers in Rust or uses its libFuzzer compatibility layer. It covers harnesses, instrumentation, modular fuzzer components, compiler wrappers, multi-core campaigns, dictionaries, crash deduplication and debugging.

When to use it. For bespoke fuzzers, unusual targets or architectures, custom mutation and feedback strategies, and fuzzing research. It is less suitable than libFuzzer or AFL++ when a simpler standard fuzzer provides the required control.
