Use when asked to set up and run coverage-guided fuzzing of Ruby code or C extensions with Ruzzy, producing crash reports or clean campaign summaries. Not for C/C++ fuzzing: use libfuzzer or libfuzzer.
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
# Ruzzy fuzzing campaign ## Contract | Field | Bound contract | |---|---| | Trigger | User needs Ruzzy to run coverage-guided fuzzing on Ruby code or a Ruby native extension. | | Authority | Reversible local: writes harness, tracer, sanitizer preload, corpus, and installed gem files to the working directory or the local Ruby gem path. Record the installed-gem list before install; rollback is file deletion plus uninstalling exactly the gem version this campaign added. No remote mutation. | | Side effect | Write Ruzzy harness scripts, tracer scripts, sanitizer LD_PRELOAD paths, corpus files, and install the target gem with clang and sanitizer flags. | | Done | Ruzzy executes the intended Ruby target with the correct tracer or extension setup and reproduces saved failures. | ## Inputs Required: Ruby target path or gem name, sanitizer selection (ASan or UBSan). Optional: corpus directory path, libFuzzer arguments (e.g., `-max_len=1024`), crash file to reproduce. ## Procedure 1. Confirm target: pure Ruby (requires tracer) or C extension (single harness). Done when: the target kind is confirmed as pure Ruby or C extension. …

How to install
mdr add outlinedriven/odin-claude-plugin/ruzzy@sha256:c841ea863676bc5bThe line at the top of this page pins the label git:20260912.6e06ed3, 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.
