fuzzing-dictionary
The agent creates and manages fuzzing dictionaries containing domain-specific tokens, magic bytes, protocol keywords, and format-specific strings to guide mutation-based fuzzers past early validation checks. It generates dictionary entries from header files, binary strings, man pages, and LLM prompts, and passes them to libFuzzer via -dict=, AFL++ via -x, or cargo-fuzz. The agent applies this technique when fuzzing parsers (JSON, XML, config files), protocol handlers (HTTP, DNS), file format processors (PNG, PDF, media codecs), or when coverage plateaus indicate the fuzzer cannot discover keyword-guarded code paths without token hints.
