fuzzgpt SKILL.md skillA
fuzzgpt from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/fuzzgpt@git:20260922.ae9c57dPins git:20260922.ae9c57d in mdr.lock. Pin the fingerprint instead.

Use when you want to fuzz any software target — library, compiler, interpreter, parser, kernel/syscall, DB engine, SMT solver, binary/file format, or network protocol — by priming an LLM with that target's HISTORICAL bug-triggering code to generate unusual, edge-case inputs (history-driven LLM fuzzing). FuzzGPT-derived: retrieval replaces fine-tuning (Deng et al., arXiv:2304.02014): mine bug reports → auto-label each snippet's buggy fuzz target → few-shot / zero-shot / retrieval generation →…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FuzzGPT — History-Driven LLM Fuzzing > **FuzzGPT-derived: retrieval replaces fine-tuning.** The original paper's FS and ZS > variants are reproduced faithfully. Fine-tuning (FT) is replaced by an > embedding-retrieval pathway (RT) — see `references/retrieval.md`. **Core hypothesis (the whole skill rests on this):** historical bug-triggering programs contain rare, valuable *code ingredients* — special values (`NaN`, `inf`, `INT_MAX`, empty/oversized inputs), edge-case shapes/sizes/lengths, 0-size dimensions, unconventional use of the target — that ordinary LLM generation never produces. LLMs trained on GitHub generate *typical* programs; fuzzing wants *unusual* ones. FuzzGPT closes that gap by priming the LLM with real past bugs instead of asking it to be "creative." This is the unusual-input engine. It pairs with `vuln-research` (which decides *what* to target and triages findings); FuzzGPT decides *how* to generate inputs that actually hit edge cases. ## The unit you fuzz: the "fuzz target" FuzzGPT steers generation toward one **fuzz target** at a time — the specific unit of functionality you want to stress (here, *the unit you point generation …

How to install
mdr add lu1sdv/skillsmd/fuzzgpt@sha256:59fc33643f597211The line at the top of this page pins the label git:20260922.ae9c57d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
