What is the Fuzzing Obstacles skill?

It is a specialized capability for Claude that provides expert strategies to overcome common technical hurdles in software fuzzing, such as complex input validation and magic value checks.

Is this skill specific to a particular fuzzer?

No, the guidance is generally applicable across various engines including AFL++, LibFuzzer, Honggfuzz, and specialized tools like Echidna for smart contracts.

How does this skill improve code coverage?

It provides actionable implementation patterns and configuration tweaks to help fuzzers navigate past checksums and state-space bottlenecks that usually block deep code exploration.

When should I use the Fuzzing Obstacles skill?

Use this skill when your fuzzer is stuck on specific code paths, failing to find new coverage, or when you are setting up a harness for a target with complex input requirements.

Who developed this skill?

This skill was authored by Trail of Bits, a premier cybersecurity research firm, as part of their professional testing handbook collection.
