fuzzing SKILL.md skillA

fuzzing from outlinedriven/odin-claude-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add outlinedriven/odin-claude-plugin/fuzzing@git:20260905.f3a3f04

Pins git:20260905.f3a3f04 in mdr.lock. Pin the fingerprint instead.

Use when planning an end-to-end fuzzing program for a project: engine and target selection, corpus management, and CI or nightly wiring. Not for harness design: use fuzz-harness-writing. Not for engine operation or triage: use libfuzzer. Not for sanitizer flag reference: use sanitizers.

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

# Fuzzing

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Coverage-guided fuzz testing for a parser, deserializer, codec, or API boundary: harness writing, libFuzzer or AFL++ setup, corpus management, crash reproduction, or CI runs. |
| Authority | Reversible local. Writes are limited to fuzz binaries, corpora, dictionaries, findings, and logs under the project tree; rollback is deleting those directories. No remote mutation. |
| Side effect | Built fuzz targets, corpus directories, crash artifacts, and coverage measurements. |
| Done | A fuzz target runs against a seeded corpus, the crash or clean verdict is reproduced on demand, and the CI or nightly plan is written down. |

## Inputs

1. Target code (required): the library or entry point to fuzz, ideally a parse or I/O boundary.
2. Seeds (required when they exist): known-good inputs from tests or real traffic.
3. Toolchain (required): Clang for libFuzzer; AFL++ installed for fork-mode fuzzing. Grounded channels: Clang 23.1.0, AFL++ v5.03c (AGPL 3.0+ since v5.00c, mixed licensing in the repo).
4. Time budget (optional): seconds for CI regression runs, hours for nightly.

How to install

The exact contents, by fingerprint
mdr add outlinedriven/odin-claude-plugin/fuzzing@sha256:727569d720eee243

The line at the top of this page pins the label git:20260905.f3a3f04, 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.
