Trail of Bits8k
Builds custom fuzzers with LibAFL, the modular Rust fuzzing library. Covers composing observers, feedbacks, mutators, schedulers, and executors into a fuzzer for targets the standard tools do not fit. Use when writing a bespoke fuzzer or mutator, fuzzing a non-standard target or architecture, implementing a fuzzing research idea, or when libFuzzer and AFL++ lack the control you need.
Install
Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.
$ npx skills add trailofbits/skills --skill libaflNeeds Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.
How to use Libafl
Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /libafl.
It contains no scripts, only instructions and reference files, so it can't run code on its own.
