About
This skill provides the LibAFL framework for building custom, advanced fuzzing campaigns to discover software vulnerabilities. It's designed for security testing scenarios where you need fine-grained control over fuzzer components like mutators, feedback, and schedulers. Use it when standard fuzzing tools are insufficient and you require a modular, library-based approach.
