# Fuzzing Dictionary

Give your fuzzer the vocabulary of the format it is attacking

## What this does

A fuzzer throwing random bytes at a parser rarely gets far, because it does not know the words the format uses. A dictionary gives it those words. Reach for this when you are fuzzing a parser, a protocol, or code that expects a specific format.

### Top 3 things it does for you

- Build a dictionary for fuzzing a parser
- Get domain-specific tokens for a protocol fuzzer

## Questions

### Is Fuzzing Dictionary safe to install?

AIR scanned this exact version of Fuzzing Dictionary and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit d5fe2e6a7896, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/fuzzing-dictionary.

### How do I install Fuzzing Dictionary?

Open https://airmarket.ai/app/fuzzing-dictionary on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
