Use when asked to build, run, or triage a coverage-guided C/C++ fuzz campaign on the libFuzzer or AFL++ engine. Not for harness design: use fuzz-harness-writing.
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
# libFuzzer and AFL++ ## Contract | Field | Bound contract | |---|---| | Trigger | User needs to build, run, tune, or triage a coverage-guided C/C++ fuzzing campaign or `LLVMFuzzerTestOneInput` harness on the libFuzzer engine (default) or the AFL++ engine (afl mode). | | Authority | Human-gated: in afl mode, request explicit user approval before a package installation or a Docker image pull; otherwise reversible local: writes only named fuzzing artifacts (binary, corpus and output directories, crash files, logs); rollback is deleting them and killing campaign processes. Kernel-tuning steps that need a reboot or degrade OS security are out of scope. No remote mutation. | | Side effect | Local write to a compiled fuzzing binary, its corpus or output directory, log files, and any crash artifacts written by the target; afl mode may run a short-lived Docker container. | | Done | The instrumented binary runs against its corpus and any crash artifact reproduces in the same target with identical sanitizer output or signal. | ## Inputs - Required: Engine: `libfuzzer` (default) or `afl`. - Required: Source or object files for the code under test. …

How to install
mdr add outlinedriven/odin-claude-plugin/libfuzzer@sha256:1a63b067a9643747The line at the top of this page pins the label git:20260905.d1af2c2, 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.
