Builds fuzzing dictionaries of keywords, magic bytes and tokens and wires them into libFuzzer, AFL++ or cargo-fuzz so fuzzers get past input validation.

trailofbits/skills

Patches checksums, hash checks, time-based seeds and other non-deterministic state out of fuzzing builds so the fuzzer reaches deeper code, with production behavior intact.

trailofbits/skills

Sets up and runs libFuzzer, the coverage-guided fuzzer built into LLVM, on C/C++ code that compiles with Clang.

trailofbits/skills

Understand a codebase before looking for bugs in it - what each function assumes, what it guarantees, and what it depends on elsewhere.

trailofbits/skills

Analyzes DWARF debug information in compiled binaries. An agent skill from trailofbits/skills.

trailofbits/skills

Performs comprehensive Rust security review for safe/unsafe boundary issues, memory safety in unsafe blocks, concurrency hazards, panic-induced DoS, FFI safety, and async runtime mistakes.

trailofbits/skills

Check code against the documentation that specifies it - which requirements hold, which the code contradicts, which are absent, and what the code does that no document mentions.

trailofbits/skills
