Afl

A comprehensive guide for writing effective fuzzing harnesses in C++, Rust, and Go. Covers harness patterns, input structuring with FuzzedDataProvider, tool-specific guidance for libFuzzer, AFL++, cargo-fuzz, and go-fuzz, plus troubleshooting tips.

This skill provides comprehensive guidance on creating fuzzing dictionaries - specialized files containing domain-specific tokens that help fuzzers discover bugs in parsers, protocols, and file format handlers. It covers dictionary format syntax, generation methods from various sources (LLM, headers, binaries), and integration with popular fuzzers like libFuzzer, AFL++, and cargo-fuzz.

AFL++ is a documentation skill that teaches how to use the AFL++ fuzzer for finding bugs in C/C++ code. It covers installation, harness writing, compilation, multi-core fuzzing campaigns, sanitizer integration, and coverage analysis with practical examples.
