Jeffrey Emanuel reposts his fuzz-testing agent skill: most recent security exploits could have been caught by fuzzing

Amid a wave of security exploits, Jeffrey Emanuel reposted his fuzz-testing agent skill:
- Core claim: software parsing complex, diverse external data you don't control has no substitute for fuzzing—intelligently generating huge numbers of varied inputs to find parsing bugs fixed valid inputs won't surface
- The skill covers coverage-guided, structure-aware, differential, grammar-based, stateful, network-protocol and web-API fuzzing across Rust, Go, C/C++, Java, Python and TypeScript
- Applicable to parsers, protocols, serialization, cryptography, state machines and file formats; he notes memory-safe Rust is still better where possible
- The skill has 2,466 installs; full content requires a subscription to his Skills.md platform
